NORTH FORK FIRE SALVAGE PROJECT, BASS LAKE RANGER DISTRICT, SIERRA
NATIONAL FOREST, MADERA COUNTY, CALIFORNIA.
EPA number: 030159F, 194 pages, April 4, 2003 PURPOSE: The
implementation of a timber salvage plan in the North Fork Fire Salvage
Project Area of the Bass Lake Ranger District, Sierra National Forest,
Madera County, California is proposed. The area was affected by a wildland
fire the burned during August 2001. As a result of the fire, there are more
dead trees per acre that are required to allow restoration of ecological
sustainability, recreation of old forest structure and function, and
provision of snags and down woody material for wildlife requiring such
habitat. Key issues identified during scoping include those related to the
lack of any stipulation within the forest management plan directing timber
harvest in the area; socioeconomics and government revenues; the economic
viability of two saw mills in the area; potential damage to soils caused by
salvage damage; the removal of trees that would not otherwise fall; and the
generation of high fuel "jack-strawed" dead trees ad tree/brush
regeneration that could cause future wildfires. The proposed action and a
No Action Alternative are considered in this final EIS. The proposed action
would result in the harvest of dead timber on approximately 530 acres via
helicopter logging, using eight existing landings. The plan would include
minor hand/jackpot pile and burn to allow for the planting of native
ponderosa pine and followup hand release for the seedlings across 270 to
350 acres. Felling of small dead trees with trunk diameters of less than 16
inches at breast height would be conducted on 80 acres. Four of the largest
snags per acre, on a 10-acre basis, would be retained. POSITIVE IMPACTS:
Plan implementation would reduce fuel loadings in the area significantly in
the near-term, thereby reducing the risk of wildland fire. In general,
forest health and diversity would be enhanced, and the forest would
progress toward a condition more closely resembling the historical
ecosystem. Timber generated by harvest would contribute to the local
economy and provide wood products for regional consumption. Harvest and
other activities would employ local workers. NEGATIVE IMPACTS: Fuel
loadings and fuel hazard would increase over time as trees that are
retained fall and become ground fuels with high resistance to control.
Prescribed burning would generate smoke and exhaust from harvest machinery
would add to the air pollutants generated by plan implementation. LEGAL
MANDATES: National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

QUARTZITE WATERSHED MANAGEMENT PROJECT, THREE RIVERS RANGER DISTRICT,
COLVILLE NATIONAL FOREST, WASHINGTON.
EPA number: 030170F, 331 pages, April 10, 2003 PURPOSE: The
implementation of watershed management activities in the
Thomason-Sherwood-Cottonwood Creek area of the Three Rivers Ranger
District, Colville National Forest, Washington is proposed. The 23,311-acre
area, known as the Quartzite Watershed, is located just east of Chewelah.
Management activities in the project area would include activities to
address vegetation enhancement, riparian /wetland management, and roads.
Management issues identified in the forest plan include those associated
with road management, the Betts Meadows Wetland Preserve, and forest
health. Seven alternatives, including a No Action Alternative (Alternative
A), are considered in this draft EIS. The proposed action (Alternative B)
would involve 4,446 acres of timber sale activities, 6,342 acres of
non-commercial thinning and prescribed fire, construction of 10.83 miles of
new road, and reconstruction of 35.52 miles of existing road. Approximately
1.8 miles of open road would be closed, and road drainage would be improved
at six stream crossings. Stream channel improvements would be implemented,
and riparian species would be planted within 100 acres at Woodward Meadows.
Mitigation measures would address water quality, soils, air quality,
noxious weeds and competing vegetation, heritage sites, visual resources,
fish and wildlife habitat, and mineral resource extraction. Monitoring
provisions would address snag retention, visual quality objectives, soils,
insect infestation and plant disease control, and water quality. The
preferred alternative (Alternative J) would provide for 1,748 acres of
commercial timber harvest, yielding 16.3 million board-feet, and 3,479
acres of non-commercial thinning and prescribed fire. Riparian/wetland
management activities would take place in the Woodward Meadows riparian
area. The plan would involve construction of 2.33 miles of road,
reconstruction of 35.05 miles of road, and closure of two roads extending a
total of two miles. Six stream crossings would be improved. Present net
value of the preferred alternative is estimated at just over $1.5 million.
Cost of implementing the plan is estimated at $4.1 million. POSITIVE
IMPACTS: Vegetation management activities would improve ecosystem integrity
by moving vegetation toward the natural range of variation; by developing
forest matrix, patches, and corridors that would be consistent with fire
landscapes; and by improving the landscape patterns of habitats for native
and desired non-native species. Riparian and wetland management activities
would improve stream channels and increase the diversity of native
vegetation. In-stream fish habitat would also be enhanced. Road management
activities would improve stream crossings and upgrade and maintain roads
necessary for long-term land management and public access. The plan would
generate $12.6 million in revenue. NEGATIVE IMPACTS: Timber harvest, road
reconstruction, and prescribed burning would result in disturbance of
vegetation, erosion, and sedimentation of receiving waters in the
short-term. Wildlife habitat, including big game habitat, and fish habitat
would be affected by these measures. Visual and other recreational
resources would also be affected. LEGAL MANDATES: National Forest
Management Act of 1976 (16 U.S.C. 1600 et seq.). PRIOR REFERENCES: For the
abstract of the draft EIS, see 02-0456D, Volume 26, Number 4.

MISSIONARY RIDGE BURNED AREA TIMBER SALVAGE PROJECT, COLUMBINE RANGER
DISTRICT, SAN JUAN NATIONAL FOREST, LA PLATA COUNTY, COLORADO.
EPA number: 030098D, 446 pages and maps, March 10, 2003 PURPOSE: The
salvaging of timber and related activities in the Missionary Ridge burned
area of the Columbine Ranger District, San Juan National Forest, La Plata
County, Colorado are proposed. The 70,480-acre area suffered a fire that
burned from June 9 to July 17, 2002. Key issues identified during scoping
include those related to forest health, recovery of timber values, roads
and the transportation system in general, and soils, erosion, and flooding.
Four alternatives, including a No Action Alternative (Alternative 1), are
considered in this draft EIS. The preferred alternative (Alternative 4)
would involve salvage harvest on 4,136 acres, Approximately 760 acres would
be salvage harvested in the roaded portion of the Florida Roadless area. No
permanent road would be constructed for the salvage operation, though
approximately 3.5 miles of temporary road would be required. Timber harvest
would generate 13.8 million board-feet of conifer saw timber and 2,512
cunits of aspen products. Trees would be harvested using standard
ground-baed?, cable (skyline), and helicopter logging systems. Ground-based
system would be utilized over 3,161 acres, skylogging over 332 acres, and
helicopter logging over 643 acres. Ground-based logging would be employed
on slopes of less than 40 percent, while helicopter and skyline logging
would occur on slopes of up to 75 percent. Some 31 miles of existing forest
road used to implement harvest would need little or no maintenance. The
remaining 55 miles of existing road would need some type of pre-haul
maintenance or reconstruction to make them suitable for log hauling. The
bulk of timber harvest activities would be probably be completed by the
fall or early winter of 2003. Present net value of the preferred
alternative is estimated at $245,542. POSITIVE IMPACTS: Plan implementation
would meet forest plan goals for vegetation and timber management in the
analysis area; more specifically, the plan would provide for appropriate
wood fiber production and utilization in the portion of the analysis area
suited for timber production. Salvage of dead and dying trees would help
meet the local and national demands for timber products. The plan would
also reduce potential fuel loading due to the large quantity of heavy fuels
that would become part of the fuel profile as fire-killed timber falls to
the ground. NEGATIVE IMPACTS: Harvest and road construction activities
would result in the generation of fugitive dust, the loss of vegetation and
the associated wildlife habitat, and increase in traffic and noise levels
during operations. Disturbance of soils would result in a short-term
increase in sediment levels in receiving surface waters. Harvest in the
Florida Roadless Area would decrease its wilderness values. LEGAL MANDATES:
National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

LAND AND RESOURCE MANAGEMENT PLAN FOR THE CHEROKEE NATIONAL FOREST,
TENNESSEE.
EPA number: 030104D, Summary--29 pages, Draft EIS--562 pages, Management
Plan--419 pages, Map Supplement, CD-ROM Appendices--389 pages, March 12,
2003 PURPOSE: The revision of the land and resource management plan for
the Cherokee National Forest (CNF) of Tennessee is proposed. The national
forests in the Southern Appalachian area have applied several efforts to
begin their revisions. A key part of that analysis, for significant
portions of each forest, has been the Southern Appalachian Assessment. The
640,000-acre CNF is the largest wildlife management area and single largest
tract of public land in Tennessee. The forest is within a day's drive of 20
million people. Each of the forests four ranger districts encompasses
approximately 160,000 acres. Approximately 90 developed recreation sites
and more than 600 miles of trails are scattered throughout the CNF. The
forest also includes 66,389 acres of designated wilderness in 11 different
tracts. Nine alternatives, including a No Action Alternative (Alternative
F), which would perpetuate the current management regime, are considered in
this draft EIS. Seven alternatives are considered in detail. The preferred
alternative (Alternative I) would respond to extensive public input to
address issues related to watershed health, recreation, sustainable
ecosystem management, the forest road system, watershed health and water
quality, habitat for wide-ranging species, habitat for threatened and
endangered species, old-growth forest, semiprimitive /remote recreation
opportunities, roadless areas, lands suitable for timber harvest, and the
President's Health Forest Initiative. The new management plan would differ
from the existing plan in the areas of forest allocations, old-growth
management, watershed management, wilderness management, timber harvest,
and management of roadless areas. The preferred plan would allow for 21.98
million board-feet of timber harvest. POSITIVE IMPACTS: The plan would
emphasize the restoration and maintenance of forest ecosystems to provide
high-quality water and diverse, resilient, self-reproducing aquatic
populations in damaged and undamaged streams. Riparian areas would be
managed to retain, restore, and/or enhance the inherent ecological
processes and functions of the associated aquatic, riparian, and upland
components within riparian corridors. The plan would promote the
sustainability of diverse ecosystems that support viable plant, wildlife,
and fish populations, including habitats for those species needing large
contiguous forested landscapes. A variety of old-growth communities would
help meet biological and social needs. Forest health measures would help
prevent insect infestations and disease outbreaks. High-quality
recreational opportunities would be available, including outstandingly
remarkable river values and scenic areas. Fuel loading would decrease
significantly in some areas, reducing the possibility of wildland fire.
NEGATIVE IMPACTS: Timber harvest, use of prescribed fire, recreational
facility development, and trail and road construction and maintenance would
result in disturbance of soils and destruction of vegetation and the
associated wildlife habitat and the sedimentation of receiving surface
waters in the short-term in the vicinity of sites affected by these
measures. Management activities would also alter the landscape and could
degrade the value of inventoried roadless areas. Habitat loss and increased
recreational visitation would reduce wildlife populations in some areas.
Both the extent and distribution of mature forest stands would be
decreased. Fire hazard ad resistance to control would increase subsequent
to the designation of more areas as either wilderness or allocations that
would not be favorable to management activities; these designations would
result in increased accumulation of forest residues. LEGAL MANDATES:
National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

LAND AND RESOURCE MANAGEMENT PLAN, JEFFERSON NATIONAL FOREST,
VIRGINIA.
EPA number: 030106D, Summary--32 pages, Draft EIS--497 pages, Management
Plan--507 pages, Appendices--495 pages, March 12, 2003 PURPOSE: The
revision of the 1985 land and resource management plan for the 723,000-acre
Jefferson National Forest of Virginia is proposed. The new plan would be in
effect for 10 years. The revised management direction would be coordinated
with that of the national forests in Alabama, the Cherokee National Forest
in Tennessee, Chattahoochee-Onconee National Forest in Georgia, and Sumter
National Forest in South Carolina. Key issues identified during scoping
include those related to terrestrial plants and wildlife and their
associated habitats, threatened an endangered and sensitive species,
old-growth forest, riparian area management, water quality and aquatic
habitat, wood products, visual aesthetics, recreation opportunities,
roadless areas and wilderness management, forest health, special areas and
rare communities, wild and scenic rivers, access and road management,
minerals, special uses, fire management, impacts on local communities,
subsurface property rights, the Mount Rogers National Recreation Area, air
quality, and land acquisition, deposition, and exchange. Seven alternatives
developed in detail, including a No Action Alternative (Alternative F) are
considered in this draft EIS. The preferred alternative (Alternative I)
would emphasize management of forest ecosystems through restoration and
maintenance. Garden Mountain and Hunting Camp/Little Wolf Creek would be
recommended to Congress for wilderness consideration, and 11 wilderness
additions would be recommended. Three new areas, not inventoried as
roadless would also be recommended for wilderness protection. The plan
would also include recommendations for wild and scenic and recreational
rivers and the Appalachian Trail corridor within the forest. Forest health
improvement activities would include replacement of off-site species,
thinning of overstocked stands, and restoration of fire-dependent and
fire-associated communities. Timber management would generate 21.7 million
board-feet of wood products. POSITIVE IMPACTS: The preferred alternative
would provide for sustainable and diverse ecosystems that support viable
vegetation, wildlife, and fish populations; allow for high-quality,
nature-based recreation opportunities, particularly in non-motorized
settings with high quality landscapes; maintain or increase habitat for
species needing large, contiguous forested landscapes and species needing
openings; and help to conserve and recover threatened, endangered,
sensitive, and locally rare species. A spectrum of high-quality,
nature-based recreation settings would be provided. All existing
inventoried old-growth forest would be protected as well as future
old-growth patches NEGATIVE IMPACTS: Road construction, timber management,
recreation facility development, and other management activities would
displace vegetation and the associated wildlife habitat temporarily and, in
some cases, permanently. Management activities and increased disturbance
due to increased numbers of recreations also affect vegetation and soils
and result in increased sedimentation of receiving surface waters. LEGAL
MANDATES: National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

NATIONAL FORESTS IN ALABAMA.
EPA number: 030136D, Draft EIS--651 pages, Management Plan--401 pages,
Appendices--421 pages, March 26, 2003 PURPOSE: The revision of the land
and resource management plan for the national forests in Alabama is
proposed. The forests extend over four different eco-regions. The Bankhead
National Forest in the northwest portion of the state is part of the
Cumberland Plateau eco-region. The Talladega Division of the Talladega
National Forest falls within the Ridge and Valley eco-region in the eastern
portion of the state. The Oakmulgee Division of the Talladega National
Forest and the Tuskegee National Forest are part of the Upper Coastal Plain
eco-region in central Alabama. The Conecuh National forest lies within the
Lower Coastal Plain eco-region in southern Alabama. Taken together, the
forests encompass approximately 665,000 acres of federal lands. The
management direction would be coordinated with other national forests in
the southern Appalachians. Key issues related to all of the affected
forests include those associated to terrestrial plants and wildlife and
their associated habitats; threatened and endangered and sensitive /locally
rare species; old growth; riparian area management, water quality, and
aquatic habitats; wood products; aesthetics/scenery management; recreation
opportunities; roadless areas and wilderness management; forest health;
special areas and rare communities; wild and scenic rivers; and access/road
management. Issues unique to the Alabama forests include those related to
the role of fire and associated air quality impacts; fixed communication
sites; the status of the Tuskegee National Forest as a Demonstration
Forest; the status of the Bankhead National Forest as a National Recreation
Area; red-cockaded woodpecker habitat; land exchange and land acquisition;
and mineral resource exploitation. Eight alternatives, including a No
Action Alternative (Alternative F), are considered in detail in this draft
EIS. The preferred alternative (Alternative I) would address each of these
issues. The plan would remain in effect for 10 to 15 years. POSITIVE
IMPACTS: While providing for a variety of recreational experiences and
multiple-use, sustainable economic exploitation of the forests resources,
the preferred alternative would protect the forests' natural and cultural
resources. NEGATIVE IMPACTS: Allocation decisions that would not allow for
the production or use of most of the available renewable resources for
relatively long periods of time would include those that provide for
wilderness areas, roadless areas, scenic areas, wild and scenic rivers,
recreation sites, and the construction of new roads. By contrast, areas not
allocated to these uses could be degraded by exploitative uses. LEGAL
MANDATES: National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.)
and National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

NORTH KENNEDY-COTTONWOOD STEWARDSHIP PROJECT, EMMETT RANGER DISTRICT,
BOISE NATIONAL FOREST, GEM AND VALLEY COUNTIES, IDAHO.
EPA number: 030137FS, 167 pages, March 26, 2003 PURPOSE: The
implementation of the North Kennedy-Cottonwood Stewardship Project within
the Emmett Ranger District of the Boise National Forest, Gem and Valley
counties, Idaho is proposed. The 8,600-acre area under consideration lies
approximately seven miles northeast of Ola. Key issues identified during
scoping include those related to open roads and related impacts to wildlife
and road construction/closure versus decommissioning. The plan would modify
the existing road system in a manner that is responsive to the diversity of
public and forest management needs identified for this specific area. Elk
vulnerability would be reduced and security habitat improved through a mix
of seasonal and year-round road closure restrictions placed on
approximately 31 miles of road and the decommissioning of six miles of
road. Seven miles of road would be reconstructed to reduce erosion and
sediment delivery to nearby streams. Three culverts that constitute
mitigation barriers hampering fish access to usable habitat would be
replaced or renovated. Commercial and noncommercial timber management
methods would be applied on 3,646 acres to improve forest health. Tractor,
skyline, and helicopter yarding would be employed in timber harvesting.
Silvicultural activities would include harvesting softwood from 3,434 acres
through commercial thinning and shelterwood entries as well as improvement,
liberation, and saitatin cuts; 45 acres of precommercial thinning; and 167
acres of tree planting. A shaded fuel break would be created on 117 acres
of activity fueled treated via low-intensity burning. Post-harvest,
non-commercial thinning and thinning from below of sub-merchantable trees
would occur on 3,480 acres of previously harvested stands. Ponderosa pine
trees would be planted on 1,275 acres following mechanical site
preparation. Three alternatives, including a No Action Alternative
(Alternative 1), are considered. The preferred alternative, outlined above,
is Alternative 2. POSITIVE IMPACTS: The plan would reduce big game
vulnerability and generally increase wildlife security, reduce road-related
sediment contributed to streams, improve fish habitat connectivity,
improvement management of motorized access, reduce forest susceptibility to
severe wildfire and western spruce budworm, and increase long-term forest
productivity. NEGATIVE IMPACTS: Management actions, particularly prescribed
burning and timber harvesting, would destroy vegetation and cause erosion
and the associated sedimentation of receiving surface flows in the
short-term, affecting terrestrial and aquatic habitat. Prescribed burning
would degrade air quality as well in the short-term. Motorized access would
be limited during harvest operations for three to five years during timber
harvest activities. In the long-term, the extent of the road system open to
motor vehicles would decline in the summer and fall. LEGAL MANDATES:
National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

CROATAN NATIONAL FOREST REVISED LAND AND RESOURCE MANAGEMENT PLAN,
CRAVEN, CARTERET, AND JONES COUNTIES, NORTH CAROLINA.
EPA number: 030067F, Final EIS--531 pages; Land and Resource Management
Plan--142 pages, Appendices--121 pages, Record of Decision--27 pages, Map,
CD-ROM, February 19, 2003 PURPOSE: The implementation of a revised land
and resource management plan for the Croatan National Forest of Craven,
Carteret, and Jones counties, North Carolina is proposed. The management
plan would provide guidelines through the year 2012. The 161,000-acre
national forest is located on the eastern coastal plain of North Carolina.
Perhaps the most interesting topographic features of the forest are its
pocosins, which occur at the upper, rather than lower end, of its
drainages. The plan would include new management areas and management
prescriptions. New management direction would be provided for recovering
the red-cockaded woodpecker (RCW) population, recreational site
developments, restoration of longleaf pine, fire management, and access
management. Issues identified during scoping include those related to
biological diversity, recreational opportunities, special land allocations,
forest products and forest health, fire management, access, and local human
communities. Five alternatives, including the No Action Alternative
(Alternative A), which would continue the current management regime, are
considered in this final EIS. The preferred alternative (Alternative E)
would address public concerns with respect to active longleaf pine
restoration, expansion of the RCW population, more habitat for black bears,
neotropical birds, and turkeys, and more intensive fuel management in
wildland-urban interfaces. Alternative E would provide for restoration of
natural communities using a two-aged silvicultural system.Emphasis would be
placed on restoring longleaf pine to sites currently occupied by loblolly
pine. Expansion of RCW populations would be actively pursued via a
long-term objective of maintaining RCW clusters within a 690,000-acre RCW
Habitat Management Area. RCW forage quality would be maintained by burning
upland pine types on 2,000 acres each year. Fuel loadings would be reduced
in wildland-urban interfaces and pocosins. Recreation would be primarily
nature-based, and further recreational development would emphasize the
Croatan as a unique natural setting for a variety of recreational
opportunities. Boundary adjustments would be proposed for recommendation as
wilderness, bringing the total wilderness within the forest to 31,912
acres. Segments of White Oak River and Brice Creek would be protected as
appropriate due their eligibility for inclusion in the National Wild and
Scenic Rivers System. Approximately 25,723 acres would be designated as
suitable for timber production, and 161,000 acres would be treated to
reduce fuel loading. Road closures would affect 15 ro 20 miles of road,
seasonal access would be restricted on 15 to 20 miles, and 20 to 30 miles
of off-highway-vehicle (OHV) trails would be designated for OHV use.
POSITIVE IMPACTS: Habitat for RCW populations would improve substantially.
Wilderness and wild and scenic river values would be preserved. The
potential for wildfire would decline substantially. Timber employment and
annual income would increase significantly. Annual recreation-related
employment and income would increase as well, NEGATIVE IMPACTS: Timber
harvest and prescribed burning would result in increased erosion and
sedimentation of receiving waters and would degrade visual aesthetics and
displace habitat for wildlife dependent on dense forest. OHV would also
contribute to erosion and sedimentation. LEGAL MANDATES: National Forest
Management Act of 1976 (16 U.S.C. 1600 et seq.). PRIOR REFERENCES: For the
abstract of the draft EIS, see 00-0080D, Volume 24, Number 1.

KACHINA VILLAGE FOREST HEALTH PROJECT, MORMON LAKE RANGER DISTRICT,
COCONINO NATIONAL FOREST, COCONINO COUNTY, ARIZONA.
EPA number: 030071F, 334 pages, February 20, 2003 PURPOSE: The
implementation of a plan to improve forest health and reduce wildfire
potential in the 10,417-acre Kachina Village area of the Mormon Lake Ranger
District, Coconino National Forest, Coconino County, Arizona is proposed.
The project area lies adjacent to the community of Flagstaff in northern
Arizona. Key issues identified during scoping include those relaetd to the
impacts of management activities on old growth, wildfire potential, and
impacts on soil, water quality, and wildlife habitat. Five alternatives,
including a No Action Alternative (Alternative B), are considered in this
final EIS. The preferred alternative (Alternative A) would thin trees and
implement broadcast burning as well as implementing improvements in
recreational areas and road management activities. Thinning would occur on
nearly 4,800 acres and broadcast burning would occur on 6,300 acres. In
addition, the plan would involve development of several new trails,
designation of dispersed camping areas, and closure of high fire risk areas
to camping. Alternatives C and D would place diameter limits on the size of
trees to be thinned. Alternative E would treat most of the project area
without the use of mechanical equipment and treat the areas immediately
adjacent to homes with a more intensive approach than the other
alternatives. All alternatives treat the same areas; however, the
alternatives vary by diameter limit and the intensity of treatments and the
use of mechanized equipment. Cost of the preferred alternative is estimated
at $981,210. POSITIVE IMPACTS: Timber harvest would generate $510,090 in
revenue. Thinning and prescribed burning would reduce fuel loading, thereby
reducing the potential for wildfire. Management activities would improve
forest health, wildlife habitat, and soil and watershed conditions in the
area over the long-term. The plan would reduce road density in the area.
NEGATIVE IMPACTS: Timber harvest and burning would result in disturbance of
vegetation and soils and the associated loss of wildlife habitat and
increased release of sediment into receiving surface waters. Prescribed
burning would also degrade air quality temporarily in localized areas. The
use of prescribed burning would present some danger of fire spreading to
adjacent areas, endangering public safety. Management activities would
degrade the visual quality and otherwise reduce the recreational value of
the area in the short-term. LEGAL MANDATES: National Forest Management Act
of 1976 (16 U.S.C. 1600 et seq.). PRIOR REFERENCES: For the abstract of the
draft EIS, see 02-0412D, Volume 26, Number 4.

CLANCY-UNIONVILLE VEGETATION MANIPULATION AND TRAVEL MANAGEMENT PROJECT,
HELENA RANGER DISTRICT, HELENA NATIONAL FOREST, LEWIS AND CLARK AND
JEFFERSON COUNTIES, MONTANA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL
IMPACT STATEMENT OF FEBRUARY 2000).
EPA number: 030073FS, 552 pages and maps, February 21, 2003 PURPOSE:
The harvesting of timber and other vegetative treatments and implementation
of a travel management plan within the 64,000-acre Clancy-Unionville
Implementation Area of the Helena Ranger District, Helena National Forest,
Montana are proposed. The project area includes portions of Oro Fino Gulch,
Dru Gulch, Grizzly Gulch, Nelson Gulch, Travis Creek, Whiteman Gulch,
Little Buffalo Gulch, Go Devil Gulch, Lump Gulch, Roe Gulch, Jackson Creek,
Kady Gulch, and Quartz Creek. Most treatments would occur in the
Grizzly/Oro Fino/Dry Gulch, Brooklyn Bridge,Sheep Mountain, Park Lake, and
Quartz Creek areas. Five alternatives, including a No Action Alternative
(Alternative B), were considered in the final EIS of February 2000. Two
additional action alternatives are considered in this final supplement to
the Final EIS. All action alternatives are designed to change vegetation
and travel patterns to more desired conditions. Alternative A, the proposed
action, was designed to improve overall forest health and sustainability
through a combination of silvicultural treatments and prescribed burning.
Alternative C was designed to respond to concerns expressed about risks
associated with prescribed burning, air quality, and noxious weeds.
Alternative D was designed to respond to concerns about wildlife and
wildlife habitat. Alternative E was developed by the Clancy-Unionville
Citizen Task Force. Alternative F is essentially the October 2000 Forest
Service division, which was subsequently remanded on repeal due to
insufficient analysis and disclosure of cumulative effects. The cumulative
effects and other impacts are addressed in this draft supplement, which
includes only changes that have occurred since the issuance of the final
EIS, most of which pertain to the newly considered Alternative F. Under
Alternative F, the Forest Service would implement prescribed burning on
1,301 acres of grasslands and 733 acres of savannah, 414 acres of forest
underburning, and 853 acres of mechanical treatments on savannah units. All
prescribed burn treatments would incorporate appropriate pre- and
post-herbicide treatment. Timber harvest activities would include 1,577
acres of commercial thinning, 176 acres of shelterwood treatment, 70 acres
of seedtree treatment, 31 acres of aspen treatment, and 109 acres of
clear-cut. The alternative would require construction of five miles of new
temporary road and reconstruction of nine miles of existing road.
Approximately 15 miles of existing road would be closed but left in place
to allow administrative access for weed management. The Spruce Hills,
Brooklyn Bridge, and Lump Gulch areas would be closed to timber harvest
activities from October 15th to December 1st to avert possible conflicts
with big game hunters. Watershed improvement projects would include road
rehabilitation, road stabilization, construction of erosion control
features, culvert removal, installation of larger diameter culverts, and
revegetation of cut and fill slopes. A non-motorized access system trail
would link the Brooklyn Bridge, Whiteman, and Jack Mountain areas, and the
Brooklyn Bridge Road would be converted to a non-motorized trail. Another
non-motorized trail would be established in the Little Corral Gulch area.
The Spruce Hills Road would be open to snowmobiles from December 2nd to May
14th. The present net value of Alternative F is estimated to result in a
deficit of $648,000. The benefit-coat ratio is estimated at 0.62. POSITIVE
IMPACTS: Plan implementation would provide for healthy native forest and
grassland plant communities with a wide variety of native plant species,
minimize the threat of large-scale wildfire, insure a variety of wildlife
habitats, provide a system of roads and trails to serve the needs of a
variety of forest users, produce an array of wood products on a sustainable
basis, and maintain or improve water quality and watershed conditions over
the short- and long-term. Elk habitat effectiveness and security would be
enhanced, as would old-growth forest. NEGATIVE IMPACTS: New timber harvest
would occur within wildlife corridors. Some old-growth forest would be
eliminated, as would certain areas of closed-forest habitat would be
converted to open-forest habitat. Potential for spreading of weeds would
increase. The potential for impacts to cultural resources sites would
increase. Prescribed burning would degrade air quality and aesthetics
temporarily. LEGAL MANDATES: National Forest Management Act of 1976 (16
U.S.C. 1600 et seq.). PRIOR REFERENCES: For the abstracts of the draft and
final EISs, see 99-0029D, Volume 23, Number 1, and 00-0192F, Volume 24,

EPA number: 030080D, Draft EIS--832 pages, Summary--39 pages, Land and
Resource Management Plan--227 pages, February 27, 2003 PURPOSE: The
revision of the general land and resource management plan for the
362,000-acre Sumter National Forest of Oconee, Chester, Fairfield, Laurens,
Newberry, Union, Abbeville, Edgefield, Greenwood, McCormick, and Saluda
counties, South Carolina is proposed. The forest is divided into three
ranger districts. Key issues identified during scoping include those
associated with terrestrial plants and animals and their associated
habitats; threatened, endangered, and sensitive species; old-growth
habitat; riparian area management, water quality, and aquatic habitat; wood
products exploitation; aesthetics and scenery management; recreational
opportunities; roadless areas and wilderness management; forest health;
special areas and rare communities; wild and scenic rivers; access and road
management; the Chattooga River watershed; and mineral resources
exploitation. Nine alternatives, including a No Action Alternative
(Alternative F), are considered in this draft EIS. The preferred
alternative (Alternative I) would emphasize management of forest ecosystems
through restoration and maintenance to ensure healthy watersheds; provide
for sustainable and diverse ecosystems that support viable plant, wildlife,
and fish populations; and provide for high-quality, nature-based recreation
opportunities, particularly in non-motorized settings with high quality
landscapes. Habitat conditions that are suitable for maintaining viable
populations of all vertebrate species native to the planning area would be
emphasized. Early successional habitats would be treated and maintained by
a variety of events, conditions, treatments, and activities. All river
segments eligible for consideration for inclusion in the National System of
Wild and Scenic Rivers would be managed to protect their outstandingly
remarkable values. The Chattoga River watershed would be managed to
emphasize recreation in association with the Cattooga Wild and Scenic River
corridor; maintenance of roadless values; promotion of dispersed recreation
opportunities; and improved water quality. Boating would not be allowed on
the Chattoga River above Highway 28. POSITIVE IMPACTS: The preferred plan
would restore and maintain watersheds as associated values; diversify
ecosystems for all wildlife populations, and maintain the forest's famous
recreation resources, with particular emphasis on pristine resources
associated with wild and scenic rivers and their watersheds. Production of
wood and mineral products would contribute to the local and regional
economy without significantly damaging natural resources. NEGATIVE IMPACTS:
Use of prescribed fire would degrade air quality, damage soils, and destroy
vegetation, and the associated wildlife habitat, and result in erosion and
sedimentation of receiving surface waters. Other management activities,
particularly timber harvest, and recreational uses of the forest would
alter the landscape in some areas and disturb and displace fish and
wildlife habitat. Both the extent and distribution of mature stands would
be changed. Fire hazard and resistance to fire control would increase
subsequent to the designation of more areas as wilderness or due to other
land allocations that would not be favorable to management activities.
LEGAL MANDATES: Forest and Rangeland Renewable Resources Planning Act of
1960 (P.L. 93-738), National Forest Management Act of 1976 (16 U.S.C. 1600
et seq.), and Wild and Scenic Rivers Act of 1968 (16 U.S.C. 1271 et seq.).

Preliminary Response of Herbaceous Plants to Biennial Burning Cycles
Applied at Different Dates During the Growing Season
Rideout, S; Rickard, JK; Wade, DD Natural Areas Journal [Nat. Areas J.].
Vol. 23, no. 1, pp. 38-42. Jan 2003. The increase in acreage treated with
growing-season fire during the past decade indicates that there has been
increased interest in burning to enhance southern pine forest health and
diversity. Information on how burn dates within the growing season can be
manipulated to vary the mix of species is of practical importance. The
objective of this study was to determine the response of herbaceous and
woody plants to eight, 3-week treatment application windows during a
biennial growing-season burn cycle at the Piedmont National Wildlife Refuge
in Georgia, USA. Early results indicate other environmental factors,
particularly lack of precipitation, had a greater impact on vegetation than
prescribed burning.

TROUT - WEST HAZARDOUS FUELED REDUCTION PROJECT, PIKE-SAN ISABEL
NATIONAL FOREST, TELLER, EL PASO, AND DOUGLAS COUNTIES, COLORADO.
EPA number: 030002D, 277 pages, January 3, 2003 PURPOSE: The
implementation of a fuel reduction plan within the Trout and West Creek
watersheds in the Pike-San Isabel National Forest, Teller, El Paso, and
Douglas counties, Colorado is proposed. The watersheds lie within the Upper
South Platte River drainage. Overly dense forest stands in the project area
are subject to damaging crown wildfires that can threaten homes and
communities, mature forest stands, and the Denver municipal water supply.
Key issues identified during scoping include those associated with crown
fire hazard, vegetation conditions, forest pathogens, soil and water
resources, fish and wildlife habitat, noxious weeds and range resources and
special plant species, air quality, visual quality, recreation resources,
and socioeconomic impacts. Seven alternatives, including a No Action
Alternative, are considered in this draft EIS. The proposed action, which
is also the preferred alternative, would include thinning and prescribed
burning within approximately 20,170 acres of National Forest System lands
to implement the National Fire Plan and the Pike and San Isabel National
Forest Land and Resource Management Plan. The plan would implement heavy
thinning on over 18,000 acres, including 13,380 acres of tractor harvest,
3,890 acres of helicopter harvest, and 950 acres on which no yarding would
be implemented. Approximately 1,945 acres would undergo light thinning.
Prescribed burning activities would include 10,660 acres of pile burning
and 6,600 acres of broadcast burning. Approximately 68 miles of system road
would be maintained or reconstructed within the project area to facilitate
operations. Approximately 14 miles of temporary road would be constructed
and then obliterated and reclaimed when no longer needed. An additional 48
miles of existing non-system roads would be upgraded for use during project
implementation and obliterated and reclaimed afterwards. Cost of plan
implementation is estimated at $13.0 million. The present net value is
estimated to result in a loss of $80 million. POSITIVE IMPACTS: Plan
implementation would reduce the risk of wildland fire in the project area,
providing protection to forest resources, residents and visitors, and the
Denver municipal water supply; the latter would suffer significantly due to
erosion following a wildfire. The plan would prevent potential damages
estimated at $160 million due to wildfire. In general, the plan would
improve forest health and the associated fish and wildlife habitat.
NEGATIVE IMPACTS: Harvest activities, road construction, and prescribed
burning would destroy vegetation and the associated wildlife habitat and
result in erosion and sedimentation of receiving waters in the short-term.
Burning would also result in short-term degradation of air quality and
scorch soils, resulting in a reduction in soil nutrient productivity. LEGAL
MANDATES: National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

NORTH FORK FIRE SALVAGE PROJECT, BASS LAKE RANGER DISTRICT, SIERRA
NATIONAL FOREST, MADERA COUNTY, CALIFORNIA.
EPA number: 030011D, 147 pages, January 8, 2003 PURPOSE: The
implementation of a timber salvage plan in the North Fork Fire Salvage
Project Area of the Bass Lake Ranger District, Sierra National Forest,
Madera County, California is proposed. The area was affected by a wildland
fire that burned during August 2001. As a result of the fire, there are
more dead trees per acre that are required to allow restoration of
ecological sustainability, recreation of old forest structure and function,
and provision of snags and down woody material for wildlife requiring such
habitat. Key issues identified during scoping include those related to the
lack of any stipulation within the forest management plan directing timber
harvest in the area; socioeconomics and government revenues; the economic
viability of two saw mills in the area; potential damage to soils caused by
salvage damage; the removal of trees that would not otherwise fall; and the
generation of high fuel "jack-strawed" dead trees ad tree/brush
regeneration that could cause future wildfires. The proposed action and a
No Action Alternative are considered in this draft EIS. The proposed action
would result in the harvest of dead timber on approximately 530 acres via
helicopter logging, using eight existing landings. The plan would include
minor hand/jackpot pile and burn to allow for the planting of native
ponderosa pine and follow-up hand release for the seedlings across 270 to
350 acres. Felling of small dead trees with trunk diameters of less than 16
inches at breast height would be conducted on 80 acres. Four of the largest
snags per acre, on a 10-acre basis, would be retained. POSITIVE IMPACTS:
Plan implementation would reduce fuel loadings in the area significantly in
the near-term, thereby reducing the risk of wildland fire. In general,
forest health and diversity would be enhanced, and the forest would
progress toward a condition more closely resembling the historical
ecosystem. Timber generated by harvest would contribute to the local
economy and provide wood products for regional consumption. Harvest and
other activities would employ local workers. NEGATIVE IMPACTS: Fuel
loadings and fuel hazard would increase over time as trees that are
retained fall and become ground fuels with high resistance to control.
Prescribed burning would generate smoke and exhaust from harvest machinery
would add to the air pollutants generated by plan implementation. LEGAL
MANDATES: National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

Inter-hemispheric comparison of fire history: The Colorado Front Range,
U.S.A., and the Northern Patagonian Andes, Argentina
Veblen, TT; Kitzberger, T Plant Ecology [Plant Ecol.]. Vol. 163, no. 2,
pp. 187-207. Dec 2002. Fire history was compared between the Colorado
Front Range (U.S.A.) and northern Patagonia (Argentina) by dating
fire-scars on 525 Pinus ponderosa and 418 Austrocedrus chilensis,
respectively, and determining fire weather on the basis of instrumental and
tree-ring proxy records of climatic variation. Years of above average
moisture availability preceding fire years, rather than drought alone, is
conducive to years of widespread fire in the Colorado Front Range and the
northern Patagonian study areas. Above-average precipitation promotes fire
by enhancing the growth of herbaceous plants which increases the quantity
of fine fuels during the fire season a few years later. The short-term
variability in moisture availability that is conducive to widespread
burning is strongly related to El Nino Southern Oscillation (ENSO)
activity. The warm (El Nino) phase of ENSO is associated with greater
moisture availability during the spring in both regions which leads to
peaks in fire occurrence several years after El Nino events. The warmer and
drier springs associated with la Nina events exacerbate the drying of fuels
so that fire years commonly coincide with La Nina events. In both regions,
there was a dramatic decline in fire occurrence after the early 1900s due
to a decline in intentionally set fires by Native Americans and European
settlers, fuel reduction by livestock grazing, and increasingly effective
organized fire suppression activities after the 1920s. In both regions
there was a marked increase in fire frequency during the mid-and late-19th
centuries which coincides with increased ignitions by Native Americans
and/or European settlers. However, year-to-year variability in ring widths
of Pinus ponderosa and Austrocedrus chilensis also increased from
relatively low values in the late 1700s and early 1800s to peaks in the
1850s and 1860s. This implies frequent alternation of years of above and
below average moisture availability during the mid-19th century when the
frequencies of major fire years rise. The high correlation of tree-growth
variability betweem the two regions implies a strong inter-hemispheric
variation in climatic variability at a centennial time scale which closely
parallels a variety of proxy records of ENSO activity. Based on the
relationship of fire and ENSO events documented in the current study, this
long-term trend in ENSO activity probably contributed to the mid- and
late-19th century increase in fire spread in both regions. These similar
trends in fire occurrence have contributed to similar patterns of forest
structures, forest health, and current hazard of catastrophic wildfire in
the Colorado Front Range and northern Patagonia.

METOLIUS BASIN FOREST MANAGEMENT PROJECT, SISTERS RANGER DISTRICT,
DESCHUTES NATIONAL FOREST, JEFFERSON COUNTY, OREGON.
EPA number: 020515D, 488 pages, December 13, 2002 PURPOSE: The
implementation of fuel reduction and forest health management activities in
the Metolius Basin on the Sisters Ranger District of the Deschutes National
Forest in Jefferson County, Oregon is proposed. The project area, which is
located in central Oregon, lies entirely within a late-successional reserve
and includes a portion of the Metolius Basin Wild and Scenic River. The
local community of Camp Sherman has voiced its concerns over the declining
health of their surrounding ponderosa pine forest lands and other forest
stands, the risk of wildfire in the area, and the degradation of water
quality in the Metolius Basin. During the past 10 years, there have been 14
large wildfires within the Sisters Ranger District. Eighty years of fire
exclusion practices have disrupted the historical fire regime, which
resulted in smaller fires every eight to 12 years. Overly dense stands have
also contributed to the area's vulnerability to insect infestation and
disease outbreaks. Key issues identified during scoping include those
related to management of vegetation in late-successional reserves,
determination of size limits for trees to be removed, fire and fuel
management; water quality and soil health, and road access. Five
alternatives, including a No Action Alternative (Alternative 1), are
considered in this draft EIS. Management actions to be undertaken would
include thinning of trees to reduce stand density, reduce stress on current
and future lace-successional forests, and reduce the risk of wildfire;
reduction of open road density to improve water quality, reduce soil
erosion and the spread of noxious weeds; and mowing of small vegetation and
prescribed burning to reduce the amount and arrangement of fuel that could
lead to wildfire. The proposed action (Alternative 4) would result in the
treatment of 12,648 acres within the area, primarily involving thinning
combined with burning and mowing. Approximately 7,332 acres would be
treated via ground-based logging systems, and 2,078 acres would be treated
by machine piling. Vegetation and fuel reduction actions would occur on
1,190 acres of riparian reserves; 80 percent of these reserves would be
treated by either hand thinning or underburning, 20 percent this area would
be treated by ground-based machine thinning, but this would only occur in
the drier, upland soils within the riparian reserves. Approximately 50
miles of road would be inactivated or decomissioned, leaving 83 miles of
open road and resulting in an average open road density of 3.1 miles per
square mile. The plan would be initiated in 2003. Present net value for the
preferred alternative is estimated to result in a loss of $4.2 million.
POSITIVE IMPACTS: The plan would significantly reduce the risk of wildfire
in the area; protect people, property, and tribal and natural values;
restore old-growth forest stands; and enhance water and soil quality.
Habitat for species associated with more open forest conditions, including
white-headed woodpecker, bald eagle, and goshawk, would be enhanced.
NEGATIVE IMPACTS: Over half of the project area would remain at risk for
mixed and high-severity wildfire. Management actions would result in
destruction of vegetation and the resulting disturbance of soil and
sedimentation of receiving waters in the short-term. LEGAL MANDATES:
National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

Ground Beetle (Coleoptera: Carabidae) Species Assemblage as an Indicator
of Forest Condition in Northern Arizona Ponderosa Pine Forests
Villa-Castillo, J; Wagner, MR Environmental Entomology [Environ.
Entomol.]. Vol. 31, no. 2, pp. 242-252. Apr 2002. Reintroduction of fire
and thinning have been suggested as the main practices to regain forest
health in northern Arizona ponderosa pine (Pinus ponderosa Dougl. ex
Lawson) forests. Criteria for assessing the impact of such management
practices in the forest are based on benchmark reconstructed conditions
resembling pre-European forest stand structure and on the enhancement of
tree vigor. A range of forest conditions currently exists including stands
that have been unmanaged, thinned only, thinned plus prescribed burned and
burned by wildfire. A surrogate taxon was used to assess forest condition
under criteria of maintaining habitat for native species operating at the
soil level. We assessed changes occurring in ground beetle assemblages at
the stand scale as related to changes that had occurred in forest stands
previously treated with the above treatments. A pitfall-trapping scheme was
deployed during the summer months of 1998, 1999, and 2000. A total of 4,452
specimens was caught representing 15 genera and 20 species of ground
beetles. We found that species diversity increased as the level of
disturbance increased. The indicator species assemblage found on the
wildfire treatment was represented by species in the genera Amara and
Harpalus that are characteristic of dry-open habitats. Unmanaged stands
generally had the lowest diversity and the assemblage was dominated by the
species Synuchus dubius (Leconte). The thinned only stands did not
significantly vary from unmanaged stands in species assemblage.
Cyclotrachelus constrictus (Say) was indicative of the thinning plus
broadcast burned stands. Stands that were thinned plus burned were richer
than both unmanaged and thinned only stands without a shift toward an
open-area dominant assemblage as occurred in the stands burned by wildfire.

Sampling coarse woody debris for multiple attributes in extensive
resource inventories
Waddell, KL Ecological Indicators [Ecol. Indicators]. Vol. 1, no. 3, pp.
139-153. Mar 2002. Information on the amount, distribution, and
characteristics of coarse woody debris (CWD) in forest ecosystems is in
high demand by wildlife biologists, fire specialists, and ecologists. In
its important role in wildlife habitat, fuel loading, forest productivity,
and carbon sequestration, CWD is an indicator of forest health. Because of
this, the USDA Forest Service Pacific Northwest Research Station's Forest
Inventory and Analysis (FIA) program recognized the need to collect data on
CWD in their extensive resource inventories. This paper describes a
sampling method, measurement protocols, and estimation procedures to
collect and compile data on CWD attributes within FIA's forest inventory.
The line-intersect method was used to sample CWD inside the boundaries of
the standard inventory field plot. Previously published equations were
customized to allow for easy calculation of per-unit-area values, such as
biomass and carbon per hectare, log density per hectare, or volume per
hectare, for each plot. These estimates are associated with all other
information recorded or calculated for an inventory plot. This allows for
indepth analysis of CWD data in relation to stand level characteristics.
The data on CWD can be used to address current, relevant issues such as
criteria no. 5 outlined in the 1994 Montreal process and the 1995 Santiago
declaration. This criteria assesses the contribution of forests to the
global carbon cycle by measuring such indicators as CWD, live plant
biomass, and soil carbon.

Using Forest Health Monitoring to assess aspen forest cover change in
the southern Rockies ecoregion
Rogers, P Forest Ecology and Management [For. Ecol. Manage.]. Vol. 155,
no. 1-3, pp. 223-236. 1 Jan 2002. Long-term qualitative observations
suggest a marked decline in quaking aspen (Populus tremuloides Michx.)
primarily due to advancing succession and fire suppression. This study
presents an ecoregional coarse-grid analysis of the current aspen situation
using Forest Health Monitoring (FHM) data from Idaho, Wyoming, and
Colorado. A unique feature of aspen forests in western North America is
regeneration primarily by asexual "suckering" although rare seeding events
do occur. The dominant clonal process provides the basis for this analysis.
In essence, the remaining aspen stems of previously large clones provide a
window to the past and possibly a view of the future. The author uses
baseline observations of aspen and associated tree species regeneration,
forest size and structure components, stand age, tree damage, and recent
disturbance to assess regional aspen conditions. Analysis of stands where
aspen is dominant (aspen forest type) and where aspen merely occurs (aspen
present) are presented. Basic groupings within the aspen forest type plots
were obtained by cluster analysis of 10 FHM variables derived from tree-
and plot-level measurements. Stable and unstable aspen forest types were
verified using principal component analysis. A further criterion of at
least 25% conifer species present was placed on the unstable group to
render a more conservative population estimate of instability.The unstable
aspen forest types, along with the plots having only the presence of aspen,
comprise the dynamic portion of the aspen community in this area. These
results support the hypothesis of an aspen decline within the past 100
years. However, additional regional plots and long-term remeasurements
should provide a clearer picture of the decline's extent. Altering current
and future management practices may significantly affect the rate of
change.

OAK DECLINE AND FOREST HEALTH, POTOSI AND SALEM RANGER DISTRICTS, MARK
TWAIN NATIONAL FOREST, CRAWFORD, DENT, IRON, SHANNON, AND WASHINGTON
COUNTIES, MISSOURI.
EPA number: 010528D, 256 pages, December 13, 2001 PURPOSE: The
implementation of a plan to minimize adverse impacts from insects and
disease damage within the Salem and Potosi ranger districts of the Mark
Twain National Forest in Crawford, Dent, Iron, Reynolds, Shannon, and
Washington counties, Missouri is proposed. The analysis area encompasses
192,638 areas. Large numbers of oaks are dying over thousands of acres
within the forest, especially in the two subject ranger districts. The
decline and mortality is affecting black and scarlet oak in particular.
More than 16,000 acres of mortality were mapped within the districts by
aerial survey in September 2000. Subsequent ground verification studies
showed red oak borer was associated with the damage, along with secondary
agents including Armillaria root disease, Hypoxylon cancer, and two-lined
chestnut borer. From 70 to 90 percent of the scarlet and black oaks are
affected by drought and insects, and approximately 20 percent of the
affected trees are dead. Issues identified during scoping include those
associated with visitor safety, results of area of influence environmental
analyses, insect infestation and disease affecting forest health, species
composition affecting forest health, hazardous fuels reduction, and
commercial logging. Five alternatives, including a No Action Alternative
(Alternative 1), are considered in this draft EIS. The preferred
alternative (Alternative 2) would involve a combination of commercial
harvesting and prescribed burning. A mix of commercial harvest,
non-commercial thinning, reforestation treatments, and prescribed burns
would be used to treat sites affected by declining oak stands. Prescribed
burning would be used for various primary objectives, including site
preparation for seedling development, restoration of open woodlands with
native ground cover, and reduction of hazardous fuel buildups.
Silvicultural methods would include 5,337 acres of seed tree harvest, 6,125
acres of shelterwood harvest, 4,125 acres of uneven-aged harvest, 5,758
acres of sanitation harvest and thinning, 77 acres of overstory removal,
and 500 acres of final harvest. Natural regeneration would be allowed on
16,235 acres. Timber stand improvement would consist of 6,476 acres of crop
tree release and 929 acres of pine release. Prescribed fire would be used
for 688 acres of site preparation and 947 acres of open woodland
development and for hazardous fuels reduction on 3,285 acres. The project
would require construction of 8.2 miles of road. An additional 15,599 acres
would be designated as old-growth habitat. Costs of harvesting timber are
estimated to total $5.4 million. Present net value of the plan is estimated
at $696,87. POSITIVE IMPACTS: Plan implementation would improve forest
health, treat diseased and insect-infested stands, recover valuable timber
products, promote public safety, and move the area toward the desired
future condition. Prescribed burning would improve wildlife habitat over
the short- and long-term. Timber sale receipts would amount to $6.09
million. Reduction of fuel loading would decrease the potential for large
wildland fires. NEGATIVE IMPACTS: Timber harvest, road construction, and
prescribed burning would result in short-term increases in erosion and
sedimentation of receiving waters, and prescribed burning would result in
temporary, localized degradation of air quality. LEGAL MANDATES: National
Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

WHITE PINE CREEK PROJECT RESTORATION PROJECT AND ASSOCIATED TIMBER
SALES, CABINET RANGER DISTRICT, KOOTENAI NATIONAL FOREST, SANDERA COUNTY,
MONTANA.
EPA number: 010535D, 423 pages and maps, December 18, 2001 PURPOSE:
The harvesting of timber and the implementation of associated prescribed
fire and watershed restoration treatments and related activities in the
White Pine Creek and Little Trout Creek drainages within the Cabinet Ranger
District of the Kootenai National Forest, Sanders County, Montana are
proposed. The 40,355-acre study area lies approximately five miles south of
Trout Creek. Key issues identified during scoping include those related to
transportation systems (access), scenic resources, watershed resources and
fish habitat, wildlife security, and old-growth habitat. Five alternatives,
including a No Action Alternative (Alternative 1), are considered in this
draft EIS. The preferred alternative (Alternative 4) represents a
modification of the proposed action (Alternative 2) developed to address
issues associated with the visual impacts of timber harvest and forest
health. Alternative 4 would also expand the opportunities to meet
vegetation restoration and big game forage needs. The plan would include
harvesting on approximately 3,087 acres to generate 23.2 million board-feet
of timber, implementation of prescribed burning on 7-3 acres, treatment of
larch mistletoe on 285 acres, obliteration of 34 miles of existing road to
improve watershed conditions, restoration of 6.7 miles of stream channel,
fish habitat improvements along four miles of stream, enlargement of two
trailheads, enhancement of lynx habitat by creating forage through
regeneration treatments on 262 acres, and restoration of aspen stands on
five acres. Alternative 4 would include reconstruction of approximately 58
miles of existing roads, construction of approximately seven miles of new
permanent system road, and construction of five miles of temporary road.
Implementation of Alternative 4 would require an approval from the regional
forester to exceed the 40-acre opening size constraint on timber harvest
and would require forest plan amendments to allow the harvest of commercial
timber in designated old-growth areas, a short-term reduction in snag
habitat in one management area (MA-10), and an allowance of additional open
road density in another management area (MA-12). Present net value of the
preferred alternative is estimated at $3.4 million, and the benefit-cost
ratio of the plan is estimated at 2.98. POSITIVE IMPACTS: The plan would
create early successional stages through regeneration in stands that are
highly infected by root disease and white pine blister rust; manage
selected mid-successional stands through silvicultural treatment to assist
these stands to develop into late successional stands, including old
growth; maintain existing old growth through management activities where
old-growth characteristics currently exist but are being affected or lost
due to the ingrowth of undesired species, mainly Douglas-fir and grand fir;
and reduce understory vegetation and fuel characteristics through
prescribed fire to maintain and enhance ponderosa pine communities, thereby
increasing the sustainability of these areas. NEGATIVE IMPACTS: Road
density in the affected area would increase during timber sale activities.
Timber harvesting, road construction, and prescribed burning would result
in erosion, destruction of vegetation, and sedimentation of receiving
waters in the short-term. Snag habitat would decline somewhat in the
short-term. LEGAL MANDATES: National Forest Management Act of 1976 (16
U.S.C. 1600 et seq.).

SHEEP FLATS DIVERSITY UNIT, GRAND MESA, UNCOMPAHGRE, AND GUNNISON
NATIONAL FORESTS, MESA COUNTY, COLORADO (FINAL SUPPLEMENT TO THE FINAL
ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1998).
EPA number: 010385FS, Final Supplemental EIS--42 pages, Record of
Decision--26 pages and map, October 10, 2001 PURPOSE: The harvesting of
timber and the implementation of ecosystem management activities in the
Sheep Flats project area of the Collbran Ranger District within the Grand
Mesa National Forest, located in Mesa County, Colorado, are proposed. The
14,467-acre project area is located on the north side of the national
forest and 12 miles south of the community of Collbran. Most of the spruce
/fir and aspen timber stands within the project area are in mature and
old-growth structural stages. The proposed action is to improve forest
health and habitat diversity by removing competing trees; removing
low-vigor, damaged trees that are susceptible to insects and disease;
encouraging the growth of Engelmann spruce within spruce/fir stands; and
increasing vertical and horizontal stand diversity. Five alternatives,
including a No Action Alternative (Alternative 1), were considered in the
June 1998 final EIS. The preferred alternative (Alternative 5) would
involve the harvesting of 14.5 million board feet (MMBF) of timber from
3,441 acres. Harvesting methods would include shelterwood (1,452 acres),
intermediate thinning (561 acres), group selection (834 acres), and
clearcutting (594 acres). A commercial firewood sale would be offered on 93
acres, and firewood for personal use would be offered on 220 acres.
Approximately 8.4 miles of new local intermittent roads and 14.6 miles of
temporary road would be constructed, 3.9 miles would be reconstructed, and
6.1 miles would be reconditioned. Road construction/reconstruction and road
closure/obliteration costs were estimated at $346, 918 and $14,379,
respectively, at the time of the final EIS. Present net value of the
preferred alternative was estimated at $547,274, and the benefit-cost ratio
is estimated at 1.43. This draft supplement to the final EIS provides
additional information on soils and water quality. POSITIVE IMPACTS: Timber
generated by the sale would boost the local and regional economies, and
harvest activities would employ local residents. Management prescriptions
would increase individual tree growth rates, reestablish Engelmann spruce
in the project area, replace mature and overmature tree stands with younger
stands, and increase vertical and horizontal stand diversity. NEGATIVE
IMPACTS: The proposed harvest activities would alter the wilderness
character of two roadless areas, would adversely affect 1,232 acres of old
growth, and could adversely affect habitat of the goshawk and other
sensitive species dependent on old growth. Wildlife habitats would be
fragmented by road construction and harvesting. Fire hazards would increase
in the short term after the timber harvesting as a result of ground-level
accumulation of harvest residues. LEGAL MANDATES: National Forest
Management Act of 1976 (16 U.S.C. 1600 et seq.). PRIOR REFERENCES: For the
abstracts of the draft and final EISs, see 97-0337D, Volume 21, Number 5,

BIG GAME WINTER RANGE AND BURNED AREA WEED MANAGEMENT ON THE LOLO
NATIONAL FOREST. MISSOULA, MINERAL, SANDERS, GRANITE, POWELL, LEWIS AND
CLARK, FLATHEAD, RAVALLI, AND LAKE COUNTIES, MONTANA.
EPA number: 010297F, Final EIS--278 pages, Record of Decision--51 pages,
August 3, 2001 PURPOSE: The implementation of a plan to control invasive
weed species in the Lolo National Forest, Missoula, Mineral, Sanders,
Granite, Powell, Lewis and Clark, Flathead, Ravalli, and Lake counties,
Montana is proposed. The plan would address weed invasion on big game
winter ranges and potential weed invasion in five areas that burned 67,300
acres in the summer of 2000. The study area encompasses 87,400 acres,
including 20,100 acres of big game winter range and 67,300 acres of burned
area. The analysis in this final EIS deals with weeds at the landscape
scale, integrates weed and fire management practices, and examines at
proposed wildlife, forest health, fire recovery, erosion control, and weed
management activities in a coordinated treatment sequence. Four
alternatives, including a No Action Alternative (Alternative A), are
considered. The preferred alternative (Alternative D) would involve use of
prescribed fire and an integrated pest management approach, which would
constitute part of the larger forest wide integrated pest management
approach Herbicides would be applied at the ground level and via aircraft.
Invasive weeds would be controlled on a maximum of 21,750 acres. Prescribed
burning would be conducted on approximately 17,400 acres of big game winter
range. Small trees would be cut and left on the ground to provided fuel for
prescribed burning on 2,385 acres. The plan would also include incidental
mechanical treatments, reseeding, public education, biological management,
and prevention components. First-year weed treatments would not be 100
percent effective, since dormant seeds in the soil can remain viable for a
decade or longer. Follow-up treatments would be necessary. Cost of the
initial treatment is estimated at $1.9 million. POSITIVE IMPACTS: The
preferred alternative would restore forage production on weed-infested elk,
deer, and bighorn sheep winter ranges and protect associated plants and
animals from weed invasion; prevent or discourage new invaders from
establishing on winter ranges and burned areas; restore historic forest
structural conditions by reintroducing fire into conifer stands on
weed-infested big game winter ranges and on ranges that are highly
vulnerable to invasive weeds; and allow for cooperation with county and
state agencies and private landowners interested in managing invasive
weeds. The susceptibility of the treated areas to insect infestation would
decline significantly. NEGATIVE IMPACTS: Non-target plant species, most
particularly wildflowers, would be destroyed in the short-term on 30
percent of the treated acreage under the preferred alternative, these
species would be lost almost entirely under the No Action Alternative.
Human health risks due to application of herbicides would be minimal. LEGAL
MANDATES: National Forest Management Act of 1976 (16 U.S.C. 1600 et seq.).

MILL CREEK TIMBER SALES AND RELATED ACTIVITIES, PROSPECT RANGER
DISTRICT, ROGUE RIVER NATIONAL FOREST. JACKSON COUNTY, OREGON.
EPA number: 010304F, 720 pages and maps, August 10, 2001 PURPOSE: The
implementation of ecosystem management activities, including one or more
commercial timber sales involving approximately 6,300 acreS of harvest
units, in the Mill Creek area of the Prospect Ranger District, Rogue River
National Forest, Jackson County, Oregon is proposed. The 49,000-acre study
area in the Barr Creek, Ginko Creek, Union Creek, Upper and Lower Mill
Creek, Castle Creek, and Natural Bridge watersheds, all of which drain into
the Upper Rogue River. Silvicultural prescriptions would include density
management of overstocked stands and treatment of mature stands via
small-group selection or even-aged management systems. Other associated
ecosystem components would include density management of non-commercial
stands for forest health and stand development, road decommissioning,
prescribed burning for wildlife habitat improvement and fuels reduction,
and other wildlife improvement projects. Six alternatives, including a No
Action Alternative (Alternative 1), are considered in this final EIS. The
preferred alternative (Alternative 6) would treat 5,198 acres within 110
units via a variety of silvicultural treatments, including 3,222 acres of
density management in overstocked stands, 539 acres of regeneration harvest
via shelterwood seed cut, 827 acres of shelterwood removal, 208 acres of
partial shelterwood removal, 14 acres of sanitation harvest to treat
disease pockets, and 1,903 acres of density management with respect to
small-diameter trees. These treatments would yield 42.8 million board-feet
(MMBF) of commercial timber to be offered via multiple timber sales.
Logging systems would include 438 acres of tractor harvest, 2,472 acres of
harvester/forwarder harvest, 1,413 acres of skyline harvest, a combination
of tractor and skyline systems on 1,51 acres, and helicopter logging on 724
acres. Approximately 2.55 miles of new road construction and 0.6 mile of
temporary road construction would be required to support timber harvest.
Approximately 45.7 miles of system road would be decommissioned. Timber
stand improvements would take place on 2,203 acres. Prescribed burning for
natural fuel reduction would take place on 105 acres, and underburning to
improve wildlife habitat would take place on 1,546 acres. The forest plan
would be amended with respect to soil quality requirements. Cost of plan
implementation is estimated at $13.99 million, and the benefit-cost ratio
is estimated at 1.53. {IV-114} POSITIVE IMPACTS: The proposed action would
improve overall forest health by stimulating natural processes that
encourage more stable and resilient vegetation conditions; improve stand
densities and species composition in currently overstocked sapling and pole
stands; maintain or restore soil and water quality conditions and big game
winter range conditions; maintain the forest road system; and provide a
sustainable yield of commercial timber and other forest commodities.
Removal of fuels through prescribed burning would decrease the likelihood
of wildfire ignition in some areas. Thermal cover for big game would
increase from 37 to 42.4 percent within the next 10 years. The plan would
generate $21.2 million in net economic benefits, including wages and
returns to the local government. NEGATIVE IMPACTS: Harvest, road
construction, and prescribed burning activities would disturb soils and
result in sedimentation of receiving waters in the near-term. Shelterwood
harvest would reduce summer range thermal cover substantially for over 50
years. Additional thermal cover would be lost through thinning, but this
cover would recover within 10 to 20 years. Harvesting would also affect the
Upper and Lower Mill Creek big game travel corridors. Thinning practices
would delay future development of late seral forest habitat, including
habitat for spotted owls. Activities within semiprimitive unroaded land
would reduce the wilderness value of the affected areas. LEGAL MANDATES:

BIG GAME WINTER RANGE AND BURNED AREA WEED MANAGEMENT, LOLO NATIONAL
FOREST; FLATHEAD, GRANITE, LAKE, LEWIS AND CLARK, MINERAL, MISSOULA,
POWELL, RAVALLI, AND SANDERS COUNTIES, MONTANA.
EPA number: 010106D, 391 pages, April 2, 2001 PURPOSE: The
implementation of a plan to control invasive weed species in the Lolo
National Forest, located in western Montana, is proposed. The plan would
address weed invasion on big game winter ranges and potential weed invasion
in five areas that burned 67,300 acres in the summer of 2000. The study
area encompasses 87,400 acres, including 20,100 acres of big game winter
range and 67,300 acres of burned area. Issues include weeds at the
landscape scale, integrates weed and fire management practices, and
wildlife, forest health, fire recovery, erosion control, and weed
management activities in a coordinated treatment sequence. Four
alternatives, including a No Action Alternative (Alternative A), are
considered in this draft EIS. The preferred alternative (Alternative D)
would involve the use of prescribed fire and an integrated pest management
approach, constituting part of the larger forestwide integrated pest
management approach. Herbicides would be applied at the ground level and
via aircraft. Invasive weeds would be controlled on a maximum of 21,750
acres. Prescribed burning would be conducted on approximately 17,400 acres
of big game winter range. Small trees would be cut and left on the ground
to provided fuel for prescribed burning on 2,385 acres. The plan would also
include incidental mechanical treatments, reseeding, public education,
biological management, and prevention components. First-year weed
treatments would not be 100 percent effective, since dormant seeds in the
soil can remain viable for a decade or longer. Follow-up treatments would
be necessary. The estimated cost of the initial treatment is $1.9 million.
POSITIVE IMPACTS: The preferred alternative would restore forage production
on weed-infested elk, deer, and bighorn sheep winter ranges and protect
associated plants and animals from weed invasion; prevent or discourage new
invaders from establishing on winter ranges and burned areas; restore
historic forest structural conditions by reintroducing fire into conifer
stands on weed-infested big game winter ranges and on ranges that are
highly vulnerable to invasive weeds; and allow for cooperation with county
and state agencies and private landowners interested in managing invasive
weeds. The susceptibility of the treated areas to insect infestation would
decline significantly. NEGATIVE IMPACTS: Non-target plant species, most
particularly wildflowers, would be destroyed in the short-term on 30
percent of the treated acreage under the preferred alternative, these
species would be lost almost entirely under the No Action Alternative. The
application of herbicides would result in some human health risks. LEGAL

UPPER BLUE STEWARDSHIP PROJECT, DILLON RANGER DISTRICT, WHITE RIVER
NATIONAL FOREST, SUMMIT COUNTY, COLORADO.
EPA number: 010075F, Final EIS--420 pages, Record of Decision--37 pages
and maps, Map Supplement, March 8, 2001 PURPOSE: The implementation of a
stewardship project in the Upper Blue area of the Dillion Ranger District
within the White River National Forest, located in central Colorado, is
proposed. The approximately 14,000-acre area lies in the Tenmile Range
between Frisco to the north and Breckenridge to the south. The area is
bounded by Highway 9 to the east and the top of the Tenmile Range to the
west. Issues include the protection, maintenance, and enhancement of the
watershed within the project area; the improvement of long-tern forest
health and timber productivity in the project area in order to maintain
recreational values, and improve visual quality and fire resiliency; the
impact of management activities on wildlife and wildlife habitat within the
Wildlife Diversity Unit (WDU); the impact of management activities on
federally listed threatened, endangered, proposed, and sensitive wildlife
species within the WDU; and the impacts of varying levels and types of
recreational use and development in the project area, including the effects
on roads, trails, and recreation development. Six alternatives, including a
No Action Alternative (Alternative A), are considered in this final EIS.
The proposed action (Alternative B Modified) would use predominantly
uneven-aged management and prescribed fire on 2,737 acres. It would involve
the closure of 11 miles of non-system and system roads and 5.8 miles of
trails. The remainder of the travelways, including 10.3 miles of roads and
32.5 miles of trails, would be retained as part of the Forest Service
system. One overnight hut and the associated glading/trail would be
approved for winter and summer use at the Breckenridge Nordic Center.
Interpretive efforts would increase to six sites. Riparian habitat would be
improved by eliminating 12 dispersed campsites and building 19 designated
campsites in the Miners Creek drainage and by restoring the Iron Springs
meadow. The plan would include up to 450 acres of interface zone
treatments, 598 acres of broadcast burns, other fuel treatments on 2,167
acres, and 2,860 acres of timber logging, glading, and other vegetation
treatments. The estimated plan implementation cost is $2.39 million and the
present net value of the plan is a deficit of $1.9 million. POSITIVE
IMPACTS: Plan implementation would improve forest health, visual quality,
wildlife habitat, and fire resilience through the enhancement of species
and structural diversity; promote the responsible recreational use of the
area and improve watershed conditions; and implement a steward contract for
pilot testing an array of new authorities for giving national forest
managers greater administrative flexibility to improve forest conditions
and help the needs of local communities. Susceptibility of stands to
wildfire, disease, insect infestation, and dwarf-mistletoe effects would
decline. NEGATIVE IMPACTS: Habitat capacity for the pygmy nuthatch, red
squirrel, warbling vireo, northern three-toed woodpecker, and southern
red-backed vole, would decline slightly, and big game hiding cover would
decline by seven percent. Plan activities would disturb soils, and increase
the number of stream crossings. LEGAL MANDATES: National Forest Management

CLEARWATER ECOSYSTEM MANAGEMENT AND TIMBER SALE PROJECT, SEELEY LAKE
RANGER DISTRICT, LOLO NATIONAL FOREST, MISSOULA COUNTY, MONTANA.
EPA number: 010085F, 70 pages, March 13, 2001 PURPOSE: The
implementation of an ecosystem management plan and timber sale for
approximately 6,800 acres within the Clearwater Area of the Seeley Lake
Ranger District within the Lolo National Forest, located in western
Montana, is proposed. The project area is located approximately 12 miles
northeast of Seeley Lake in the Upper and East Fork Clearwater River
drainages. It lies east of Highway 83, south of the Lolo/Flathead Forest
boundary, west of the tow of the Swan Face, and north of the East Fork
Clearwater River. The area is relatively unfragmented by past harvest
activities. Crossing a valley, it provides a linkage zone between the Bob
Marshall and Mission Wildernesses for grizzly bear. Key issues identified
during scoping include those related with road management, water quality
and fisheries, vegetative condition and disturbance processes, wildlife
security and habitat, and recreational values. Seven alternatives,
including the No Action Alternative (Alternative 1), are considered in this
final EIS. The preferred alternative (Alternative 7A) would include the
logging of approximately 2.5 million board-feet of timber on 570 acres and
the prescribed burning of 310 acres. Logging activities would include 418
acres of intermediate cuts, and 152 acres of cuts designed to create
openings. The preferred alternative would include the construction of 1.6
miles of temporary road and the reconstruction of 12.1 miles of permanent
road. Approximately 12.8 miles of road would be obliterated. The estimated
costs of the projects related to the plan are $285,190. The present net
value of the plan is $126,320. POSITIVE IMPACTS: The plan would respond to
the need to reduce road densities and motorized access to protect grizzly
bear, reduce sources of sediment to protect water quality and bull trout
habitat, maintain forest health and disturbance processes to reduce the
susceptibility of lodgepole pine stands to mountain pine beetle mortality,
maintain the vigor and overall health of stands, improve wildlife habitat
by reintroducing low or moderate intensity fires and ecosystem burns,
create larger patch sizes and fire-killed stands on the landscape, treat
noxious weeds, and enhance scenic views along the Clearwater Loop Road.
NEGATIVE IMPACTS: Ground disturbing activity could adversely affect
undiscovered historic or prehistoric sites. Recreational visitors would
experience an adversely modified forest in the near foreground,
middle-ground, and background where logging and road work was implemented.
The logging and prescribed burning activities would also affect cover and
forage relationships in the area, though wildlife security objectives would
be met. Temporary seasonal degradation air quality would result from the
prescribed burning. LEGAL MANDATES: National Forest Management Act of 1976

Composition, structure and dynamics of Dysart Woods, an old-growth mixed
mesophytic forest of southeastern Ohio
McCarthy, BC*; Small, CJ; Rubino, DL Forest Ecology and Management [For.
Ecol. Manage.]. Vol. 140, no. 2-3, pp. 193-213. 15 Jan 2001. Dysart Woods
is a 23 ha old-growth remnant of mixed mesophytic vegetation located in
southeastern Ohio, USA. A designation of mixed mesophytic for this forest
has historically been difficult, in part due to the abundance of white oak
(Quercus alba); however, the dominance of a variety of other hardwoods
prevents a simple oak forest designation. Using two 0.35 ha plots on
opposing north- and south-facing slopes, we describe the structure and
composition of the overstory, understory, and soils, 30 years after their
first examination. In 1970, the woods was dominated by beech (Fagus
grandifolia), white oak, and sugar maple (Acer saccharum) -- historically,
the three most abundant species in this region. At that time, white oak was
only present in the largest size classes, was not regenerating, and was
predicted to decline in importance through succession. These patterns
continue today suggesting that inferences made via overstory-understory
relations in regards to forest succession are relatively robust over this
time period. Beech and maple have increased in importance; white oak has
decreased in importance due to mortality in the larger size classes and
decreasing density due to regeneration failure. Coarse woody debris
distributions correlated strongly with living stem species' composition and
structure implying an equilibrium balance. CWD volume and frequency were
dominated by Quercus spp. A detailed analysis of forest health showed that
all oak species were in severe decline. The oaks are in a disease decline
spiral affiliated with a variety of pre-disposing and inciting factors
which include their advanced age (>300 years), their large size (> 100 cm
DBH), topography, chronic air pollution, drought, and Armillaria root rot
fungus. Ca:Al molar ratios in the soil are also extremely low (<1.0) and
may be having an additional detrimental effect. All other canopy species
appear to be healthy. One of the unusual features of this woods is its
relatively diverse and high coverage (up to 90%) understory layer. The
herbaceous community was sampled throughout the growing season and found to
be markedly dissimilar among sample times and habitat productivity (aspect,
soil quality, and light). The role of these factors has not been as well
studied for herb communities as it has for tree communities. There appears
to be a relatively strong linkage between the overstory regeneration and
understory coverage. While a variety of woody seedlings were discovered,
most were of shade tolerant species. Only a few small seedlings of white
oak were discovered, with none advancing past 30 cm in height, indicating
strong competition in the understory. Furthermore, this small remnant
forest patch is surrounded by an agricultural and second-growth forest
matrix with many non-indigenous plants -- none of which have been able to
enter the woods, suggesting strong equilibrium stability of these
old-growth patches. The hardwood forests of the hills region has been
heavily impacted by various human cultures for thousands of years.
Dendrochronological analysis of a full basal slab cut from a wind-thrown
white oak revealed a fairly active period of fire following European
settlement. A lack of fire during the early 1600s to mid 1700s suggests
that pre-Anglo fire frequency may have been negligible. There is clearly a
continued role for the preservation and study of these old-growth remnants.
They remain integrally important as we attempt to understand and better
manage our remaining anthropogenically disturbed landscape.

Wildland Fire in Eastern Oregon and Washington
Ottmar, RD; Sandberg, DV Northwest Science [Northwest Sci.]. Vol. 75,
suppl., pp. 46-54. 2001. Wildland fire is a major disturbance agent that
shapes the forest health, productivity, and ecological diversity of eastern
Oregon and Washington. Fire behavior and the effects of fire on flora,
fauna, soils, air, and water are in large part driven by the availability
of fuels to consume and the meteorological influences during a fire.
Vegetation succession, disturbance processes, and management practices have
resulted in an increase of fuels and vulnerability to extreme fire behavior
and detrimental fire effects. Hazards of fire are further increased by
encroachment of dwellings into forests and rangelands. Prescribed fire,
selective logging, and mechanical fuel treatment are being used to reduce
fire hazard, but there is disagreement as to appropriate balance and
efficacy of these actions. New tools to (1) characterize fuelbeds; (2)
predict mesoscale meteorology, fire behavior, fire effects, smoke
production, and dispersal; and (3) demonstrate tradeoffs between prescribed
fire and other fuel treatment methods are continually being improved to
assist with wildland fire and prescribed fire decision making in eastern
Oregon and Washington.

Herbivory by Wild and Domestic Ungulates in the Intermountain
West
Kie, JG; Lehmkuhl, JF Northwest Science [Northwest Sci.]. Vol. 75,
suppl., pp. 55-61. 2001. Management of wild ungulates is seldom
undertaken with a focus on the effects on forest health and productivity
but rather focusing on populations of the ungulates and their habitat
needs. Consequently, only limited research has examined grazing and
browsing by ungulates in coniferous forests as a chronic disturbance factor
affecting nutrient turnovers, competitive interactions among plant species,
and rates and trajectories of successional pathways. Local effects are
quite variable and depend on ecosystem productivity. Grazing can have mixed
effects on species richness and the spread of exotic plants at the
landscape scale. Grazing also can affect nitrogen fixation and rate of
nitrogen mineralization. Ungulate density relative to carrying capacity of
the site largely determines the effects of herbivory. High population
densities of ungulates have been shown to change plant species composition,
growth of trees, and to damage regeneration. Grazing also reduces
accumulation of fine fuels on the forest floor, which formerly carried
low-intensity, high-frequency ground fires. Effects of wild ungulates can
be controlled by hunting regulations, and in some cases, by artificial
contraception. Effects of grazing by livestock can be controlled through
management actions such as changes in livestock numbers, changes in timing
and duration of grazing, altering livestock distribution with fencing and
placement of salt and supplemental feed, and specialized rotational grazing
systems such as deferred and rest rotation.

Climatic Variability in Eastern Oregon and Washington
Ferguson, SA Northwest Science [Northwest Sci.]. Vol. 75, suppl., pp.
62-69. 2001. Climate is a driving factor in forest health and
productivity that limits species survival and affects disturbance
processes. Complex topography and mosaics of land cover compound the
variability of climate in eastern Oregon and Washington. The area is a
transition zone between marine, arctic, and continental influences with
associated extremes in weather. Such extremes affect insect populations,
animal migration, streamflow, flooding, and wildfire potential.
Additionally, human activities such as deforestation and atmospheric
pollution interact with climate, and may cause changes similar in magnitude
to the glacial-interglacial epoch in the next 50 to 100 years. Effects of
anthropogenic climate changes are ambiguous, however, and could
counter-balance each other. For example, tree populations may have more
difficulty reestablishing, but growth rates could accelerate. Conversely,
management actions can mitigate the effect of climate on fisheries, water
resources, wildfire, and floods. Also, management actions can affect
climate by modifying carbon exchange and water and energy exchange between
land and atmosphere. Models are increasingly able to predict climate
variability and trends in climate-related disturbances such as wildfire.

Vegetative Patterns, Disturbances, and Forest Health in Eastern Oregon
and Washington
Hemstrom, MA Northwest Science [Northwest Sci.]. Vol. 75, suppl., pp.
91-109. 2001. Vegetation patterns in eastern Oregon and Washington are
largely a result of environmental conditions, species distributions, plant
ecology, and disturbances operating at multiple scales and in different
environments. In turn, vegetative patterns strongly influence the amount,
severity, and distribution of disturbances generated by various agents.
This paper focuses on the latter--the relations between vegetation pattern,
disturbance, and forest health and productivity. At all scales,
vulnerability to disturbance appears to increase when vegetation condition
and pattern differs from the historical or expected range for a given
environment. Generally, forests that are older, composed of larger trees,
denser, more homogeneous, or more contiguous than would be expected under
natural or historical disturbance regimes are more vulnerable to mortality
from insects and disease. Factors related to vulnerability include site
potential, host abundance, canopy structure, host size, patch vigor, patch
density, patch connectivity, topography, and logging disturbance. Mortality
from insects and disease contributes to diverse habitat, but current levels
of tree mortality from insects and disease are often outside the historical
or expected range given site environment. High levels of mortality may
continue because many forests have become more homogeneous, contiguous, and
dominated by shade-tolerant species owing to fire suppression and
management. Uncharacteristically severe fires will likely increase in the
next 100 years even with restoration management because of changed
vegetation patterns and other factors. Information at stand or site scales
is relatively abundant in the scientific and management literature. Much
broad-scale information is based on models and expert opinion. Research at
broad scales is scanty and difficult.
-
Old-Growth Forest Structure in Eastern Oregon and Washington
Youngblood, A Northwest Science [Northwest Sci.]. Vol. 75, suppl., pp.
110-118. 2001. Old-growth forest structure is an important issue in
managing for forest health and productivity in eastern Oregon and
Washington. Old-growth forest structure is estimated to be as little as 3%
of presettlement levels; what remains is in isolated patches and is at risk
of loss from less frequent but more severe fires. Low-elevation ponderosa
pine and Douglas-fir stands are more densely stocked with increased fuel,
and often represent compositional shifts to more lodgepole pine and grand
fir. The changes are attributed to changes in natural disturbance regimes
as a result of management of fire, grazing, timber harvest, wildlife,
insects, and disease. Treatments that can accelerate development of
old-growth forest structure include thinning to accelerate growth on
residual stems, returning fire to fire-dependent ecosystems, and
maintaining large trees and snags. These methods have risks: prescribed
fire may not mimic frequency and severity of historical fire, thinning may
activate dormant stem decay, increased connectivity may increase
susceptibility to stand-replacement fire, insects, and pathogens. Models
for multiple species and interactions of treatments, insects, and disease
are not available.

Soil, Litter, and Coarse Woody Debris Habitats for Arthropods in Eastern
Oregon and Washington
Niwa, CG; Peck, RW; Torgersen, TR Northwest Science [Northwest Sci.].
Vol. 75, suppl., pp. 141-148. 2001. Arthropods within soil, litter, and
coarse woody debris play vital roles in maintaining soil fertility, health,
and productivity. Arthropods shred plant material, help mineralize
nutrients for plants, act as predators, and serve as food for other
wildlife. Some species or groups of species are potentially valuable for
monitoring forest health. Natural and human-caused disturbance may
immediately kill many arthropods, but changes to habitat structure are
likely to cause longer-term effects on their community compositions. Fire
effects on arthropods may be minimized if refugia of litter and coarse
woody debris are retained. Possible effects of timber harvesting on
arthropods include mechanical effects on soil and litter, microclimate
changes, and the addition of organic matter to the forest floor. Soil
compaction reduces pore size, which may result in loss of habitat and
decreased nutrient retention, and changes the microbial and nematode
communities, which can affect nutrient cycling and food resources for
microarthropods. Thresholds required for healthy ecosystem function, and
predictive and decision-support tools that include these components in
relation to disturbances are not available.
-
Rare Plants of Eastern Oregon and Washington
Croft, LK Northwest Science [Northwest Sci.]. Vol. 75, suppl., pp.
149-156. 2001. Rare plants are an important consideration for managing
forest health and productivity in eastern Oregon and Washington. The
floristic diversity of this area reflects the complex biophysical
environment. There are many endemic vascular plants whose ranges lie
entirely within this region; many are restricted to very small geographic
areas or highly specialized habitats. A common element is adaptation to
natural disturbance; non-natural threats include exotic plant invasion,
agricultural conversion, road construction, recreation, fire suppression
activities, livestock grazing, herbicide spray that reduces pollinators,
and altered fire and hydrological regimes. Because various species are
adapted to different successional stages, maintaining a diversity of stages
would provide for a variety of these species. Restoration of the natural
fire regime and reduction of grazing would benefit upland shrub
communities. Mitigation of activities for rare plants is site-specific and
may include altering the timing, level of intensity, or methods used.

Effects of Disturbance on Birds of Conservation Concern in Eastern
Oregon and Washington
Bull, EL; Wales, BC Northwest Science [Northwest Sci.]. Vol. 75, suppl.,
pp. 166-173. 2001. The effects on birds of forest insects, tree diseases,
wildfire, and management strategies designed to improve forest health
(e.g., thinning, prescribed burns, road removal, and spraying with
pesticides or biological microbial agents) are discussed. Those bird
species of concern that occur in forested habitats in eastern Oregon and
Washington include the bald eagle (Haliaeetus leucocephalus), peregrine
falcon (Falco peregrinus), harlequin duck (Histrionicus histrionicus),
upland sandpiper (Bartramia longicauda), northern goshawk (Accipiter
gentilis), ferruginous hawk (Buteo regalis), and black rosy finch
(Leucosticte arctoa). In addition, seven species of woodpeckers and
nuthatches were considered because of their rare status. Forest
disturbances that create dead trees and logs are critical to cavity-nesting
birds because the dead trees with their subsequent decay provide nesting
and roosting habitat. The insects associated with outbreaks or dead trees
provide prey for the woodpeckers and nuthatches. The loss of nest or roost
trees as a result of disturbance could be detrimental to bald eagles,
goshawks, or ferruginous hawks, while the loss of canopy cover could be
detrimental to harlequin ducks and goshawks or to prey of some of the
raptors. The more open canopies created by thinning may be beneficial to a
species like the black rosy finch, yet detrimental to some woodpeckers due
to a decrease in cover. Prescribed burning may be beneficial to those
woodpeckers primarily associated with ponderosa pine (Pinus ponderosa)
stands and detrimental to other woodpeckers because of the loss of coarse
woody debris. Removal of roads is likely to benefit most of these species
because of the subsequent decrease in human activity. Recovery plans for
bald eagles and peregrine falcons are available for managers to use in
managing habitat for these species.

Effects of Disturbance on Forest Carnivores of Conservation Concern in
Eastern Oregon and Washington
Bull, EL; Aubry, KB; Wales, BC Northwest Science [Northwest Sci.]. Vol.
75, suppl., pp. 180-184. 2001. The effects on forest carnivores of forest
insects, tree diseases, wildfire, and management strategies designed to
improve forest health (e.g., thinning, salvage operations, prescribed
burns, and road removal) are discussed. Forest carnivores of conservation
concern in eastern Oregon and Washington include the Canada lynx (Lynx
canadensis), wolverine (Gulo gulo), and fisher (Martes pennanti). All three
species depend to some degree on forest structures, stands, and landscapes
created by insects, disease, and fire. Wildfire and insect outbreaks
maintain a mosaic of structural stages across the landscape that are used
by lynx. Thinning of dense lodgepole pine (Pinus contorta) stands that
result largely from wildfire and insect outbreaks is detrimental to
snowshoe hares (Lepus americanus), which are the primary prey of lynx.
Fishers use large stands of mature forest and snags, hollow live trees,
logs, stumps, witches-brooms, and other structures for rest and den sites.
Salvage harvesting, thinning, and conversion from predominantly fir stands
to ponderosa pine (Pinus ponderosa) may adversely affect habitat conditions
for fishers. Use of roads is perhaps most detrimental to wolverines because
they are easily trapped and avoid humans.

Improving Forest Health and Productivity in Eastern Oregon and
Washington
Quigley, TM; Hayes, JL; Starr, L; Daterman, GE Northwest Science
[Northwest Sci.]. Vol. 75, suppl., pp. 234-251. 2001. Forest health and
productivity decline in eastern Oregon and Washington has resulted in risks
to products, economies, and amenities that are deemed unacceptable to many
residents and non-residents. Information and management tools exist that
will assist managers in improving conditions, but what is needed is a
framework for integrating the available models and information. Steps in
developing such a framework include: establishing goals consistent across
scales, assessing current conditions and risks, developing management
options, describing outcomes of options, selecting an option, establishing
priorities for action, implementing those priority activities, and
monitoring and evaluating the results of actions. Research projects
undertaken by the Forest Health and Productivity Initiative of the Pacific
Northwest Research Station include collaboration with managers to develop
options for managing insect, disease, and fire disturbances in order to
improve ecosystem integrity, to integrate biophysical and socioeconomic
considerations, to identify linkages across scales, and to fill significant
knowledge gaps at the mid or broad scale. Science can contribute basic
understanding of resource conditions and interactions, models to assess
risk and opportunities, models that predict future conditions, and options
regarding future management actions. The ability to implement actions to
achieve improved forest health and productivity depends on the availability
of resources to plan and implement actions, the financial feasibility of
individual practices on individual sites, the motivation of resource
specialists and the public to undertake the actions, and acceptance by the

Effects of Disturbance and Management of Forest Health on Fish and Fish
Habitat in Eastern Oregon and Washington
Howell, PJ Northwest Science [Northwest Sci.]. Vol. 75, suppl., pp.
157-164. 2001. Effects of fire, forest insects and diseases, grazing, and
forest health treatments on fish populations and habitat are reviewed.
Fire, insects, and disease affect fish habitat by their influence on the
rate and volume of woody debris recruitment to streams, canopy cover and
water temperature, stream flow, channel erosion, sedimentation, nutrients,
and residual vegetation. Physical effects from fire vary greatly depending
on fire severity and extent, geology, soil, topography, and orientation of
the site, and subsequent precipitation. Most effects moderate within a
decade. Post-fire erosion and wood recruitment are also influenced by fire
lines, road construction, and timber harvest. Although some disturbances,
such as severe fire and subsequent floods, appear catastrophic, and effects
may last decades or centuries, natural disturbances help create and
maintain diverse, productive aquatic habitats. Recolonization of fish
populations following wildfires can be rapid and is related to occurrence
of local refugia, life history patterns, access for migratory forms, and
distribution of the species. In most livestock studies, grazing negatively
affected fish habitat and populations, but results may vary depending on
sites and specific grazing management. Effective approaches to grazing
management similarly depend on the specific application and the commitment
of operators and managers. Restoration of the structure, function, and
processes of watersheds more similar to those with which native species
evolved may favor those species; however, there is little documentation of
the aquatic effects of those activities. Risk from vegetative treatments
may be minimized by experimenting outside of critical areas (i.e.,
conserving key habitats and populations, focusing intensive treatments on
upland sites). Use of more benign techniques (e.g., lower-impact logging
systems) and pulsed treatments consistent with characteristics of natural
disturbance regimes are other considerations for achieving both terrestrial
and aquatic objectives.

Effects of Disturbance on Amphibians of Conservation Concern in Eastern
Oregon and Washington
Bull, EL; Wales, BC Northwest Science [Northwest Sci.]. Vol. 75, suppl.,
pp. 174-179. 2001. The effects on amphibians of forest insects, tree
diseases, wildfire, and management strategies designed to improve forest
health (e.g., thinning, prescribed burns, road removal, and spraying with
pesticides or biological microbial agents) are discussed. Those species
that occur in forested habitats in eastern Oregon and Washington that are
considered of concern include the Oregon spotted frog (Rana pretiosa),
Columbia spotted frog (R. luteiventris), northern leopard frog (R.
pipiens), Cascades frog (R. cascadae), tailed frog (Ascaphus truei), Larch
Mountain salamander (Plethodon larselli), and Cope's giant salamander
(Dicamptodon copei). Little is known regarding the effects of forest health
on amphibians, although tree mortality resulting from insects and disease
is unlikely to dramatically affect these species, except for the tailed
frog and larch mountain salamander. Both these species depend on overstory
canopy to maintain temperature and moisture conditions; timber harvest in
their habitats has rendered them unsuitable. Wildfire and prescribed
burning to a lesser extent, may alter the abundance of prey, coarse woody
debris, and vegetation, which could influence movements and survival of
dispersing amphibians. Spraying with pesticides could negatively affect
these species if the abundance of their prey is decreased. Spraying with
biological microbial agents is unlikely to affect prey abundance.
Additional research is needed to determine if these disturbance agents are
contributing to the decline of many of these amphibians.

COLVILLE INDIAN RESERVATION INTEGRATED RESOURCE MANAGEMENT PLAN, FERRY
AND OKANOGAN COUNTIES, WASHINGTON.
EPA number: 000434F, Final EIS--402 pages, Summary--26 pages, December
7, 2000 PURPOSE: The implementation of a 15-year integrated resource
management plan for the 1.4-million-acre Colville Indian Reservation,
located in northwestern Washington, is proposed. The reservation is bounded
on the east and south by the Columbia River, on the west by the Okanogan
River, and on the north by the line separating townships 34 and 35 of the
Willamette Meridian. Major land uses include 24,500 acres of agricultural
land, 673,025 acres of commercial forest, 128,348 acres of non-productive
forest, 92,852 acres of non-operable forest, 8,397 acres of wilderness,
455,276 acres of rangeland, 1,195 acres of residential land, and 7,672
acres of surface waters. The reservation is home to the Lakes, Colville,
San Poil, Nespelem, southern Okanogan, Moses/Columbia, Palus, Nez Perce,
Methow, Chelan, Entiat, and Wenatchi bands. Just less than 50 percent of
the membership lives off-reservation. The tribes currently include over
8,500 members, with the majority being under 10 years of age or between the
ages of 30 and 39 years. Approximately 55 percent of the membership is of
working age; the unemployment level is near 45 percent. Timber revenues
have historically contributed 80 to 90 percent of the tribal budget. Gaming
revenue first became a source of tribal program funding in 1996. Key issues
addressed during scoping include those related to holistic resource
management, short- and long-term value of the tribal timber resources,
timber production practices, forest health, late successional forest,
habitat diversity, threatened and endangered species, special management
areas, visual resources, watershed health, recreational resources,
livestock use of rangeland, the organization of the tribal Natural Resource
Department, and tribal membership values, expectations, and awareness.
Seven alternatives, including a No Action Alternative (Alternative 1), are
considered in this final EIS. Under the proposed action (Alternative 2),
the plan would involve the logging of 953.1 million board-feet (MMBF) of
timber from 156,989 acres from the year 2000 to 2014, prescribed burning
for non-logging fuels management on 6,400 acres, non-logging stocking
control (thinning) on 3,100 acres, and the reduction in range forage use
from 60,924 animal unit months (AUMs) to 51,785 AUMs. The present net value
of the proposed plan is $92.7 million. POSITIVE IMPACTS: The plan would
allow the economic development of tribal lands while preserving ecosystem
values. Large areas of wilderness would remain untouched. Insect and
disease vulnerability of forested lands would be reduced. Air quality
within the reservation would improve significantly. Cultural resources
would be protected. Big game security habitat would increase slightly.
NEGATIVE IMPACTS: Wildfire potential would remain at a moderate level.
Management activities would disturb 13,086 acres. A reduction in the area
available for livestock use would place economic burdens on some ranchers.
Net revenues would decline from $221.5 million to $197.7 million. Big game
forage would decline slightly. The aesthetic value of visual resources
would be adversely affected. LEGAL MANDATES: Endangered Species Act of
1973, as amended (16 U.S.C. 1531 et seq.), and National Historic
Preservation Act of 1966, as amended (16 U.S.C. 470 et seq.). PRIOR

Softwood Forest Thinnings as a Biomass Source for Ethanol Production: A
Feasibility Study for California
Kadam, KL; Wooley, RJ; Aden, A; Nguyen, QA; Yancey, MA; Ferraro,
FM Biotechnology Progress [Biotechnol. Prog.]. Vol. 16, no. 6, pp.
947-957. Nov-Dec 2000. A plan has been put forth to strategically thin
northern California forests to reduce fire danger and improve forest
health. The resulting biomass residue, instead of being open burned, can be
converted into ethanol that can be used as a fuel oxygenate or an octane
enhancer. Economic potential for a biomass-to-ethanol facility using this
softwood biomass was evaluated for two cases: stand-alone and co-located.
The co-located case refers to a specific site with an existing biomass
power facility near Martell, California. A two-stage dilute acid hydrolysis
process is used for the production of ethanol from softwoods, and the
residual lignin is used to generate steam and electricity. For a plant
processing 800 dry tonnes per day of feedstock, the co-located case is an
economically attractive concept. Total estimated capital investment is
approximately $70 million for the co-located plant, and the resulting
internal rate of return (IRR) is about 24% using 25% equity financing. A
sensitivity analysis showed that ethanol selling price and fixed capital
investment have a substantial effect on the IRR. It can be concluded that
such a biomass-to-ethanol plant seems to be an appealing proposition for
California, if ethanol replaces methyl tert-butyl ether, which is slated
for a phaseout.

Assessing the Impacts of Deer Browsing, Prescribed Burns, Visitor Use,
and Trails on an Oak-Pine Forest: Pinery Provincial Park, Ontario,
Canada
Patel, A; Rapport, DJ Natural Areas Journal [Nat. Areas J.]. no. 3, pp.
250-260. Jul 2000. An effective approach to increase forest health is to
identify and validate a suite of indicators for monitoring forest
conditions. We sought indicators of impacts due to deer browsing,
prescribed burn, visitor use, and trails on understory plants beside trails
in an oak-pine savanna in Pinery Provincial Park, Ontario, Canada. Six
commonly used ecological indicators were studied in 216 1-m x 1-m quadrats
located 0, 3, and 15 m from nine trails: plant species richness, stem
density, species cover, proportion of native species, median height of
selected tree seedlings, and proportion of foliar damage (insect herbivory)
on leaves of neighboring trees. Three levels of visitor use, two of deer
densities, and two of prescribed burns were used in analysis. Plant stem
density and cover per quadrat were sensitive to the effects of deer
density, prescribed burn, and visitor use. The proportion of native species
per quadrat was affected by prescribed burn, distance from trail edge, and
visitor use. The number of nonnative species increased along trail edges,
but numbers of native species were similar throughout. Plant species
richness, median seedling height, and proportion of foliar herbivory per
quadrat were only sensitive to deer density. Higher deer densities led to
significant declines in species richness, stem density, cover, and median
seedling height. Prescribed burns proved to be beneficial to the forest,
with stem density and cover increasing in burned areas, although the
proportion of exotic species also increased in burned areas. Surprisingly,
high visitor use had a moderately positive impact on the forest, with
density and cover increasing on trails with high visitor use, and
proportion of native species highest on trails with moderate visitor use.
Of the indicators studied in the park, stem density, cover, and the
proportion of native species responded strongly to browsing, fire, visitor
use, and trail impacts. Similar studies at other parks would help managers
to focus long-term monitoring efforts on the most sensitive site-specific
indicators.

AIRPORT FOREST HEALTH PROJECT, PACIFIC RANGER DISTRICT, ELDORADO
NATIONAL FOREST, ELDORADO AND PLACER COUNTIES, CALIFORNIA.
EPA number: 000244D, 267 pages, July 12, 2000 PURPOSE: The
implementation of understory thinning and fuels reduction within the
Airport Project Area of the Pacific Ranger District within the Eldorado
National Forest, located in eastern California, is proposed. The area,
which lies approximately 20 miles northeast of the community of Pollock
Pines, has been identified as a moderate to high fire risk area containing
values in the form of improvements and intrinsic forest resources. Extreme
fire behavior affecting adjacent lands and the large, local wildland fires
emphasize the desirability and urgency of managing the vegetation to reduce
the likelihood that wildfire conflagrations will determine the future
landscape and threaten lives and property. The project area has a higher
than average incidence of wildfire starts compared to the rest of the
Eldorado National Forest. Current vegetation conditions in the area differ
markedly from the desired historic condition and the current stands exceed
the historical range of variability in terms of higher proportions of shade
tolerant white fir and incense cedar, increased densities of trees,
unusually high levels of insect-related tree mortality, and an accumulation
of ground and ladder fuels. Issues include the risk of developed camping
areas and area improvements being destroyed by wildfire, the risk of
high-quality recreational experiences for visitors in the Crystal Basin
from catastrophic fire as well as the selected treatments, the impact of
wildfire and selected treatments on watershed conditions, the effect of
catastrophic fire on the socioeconomic well-being and vitality of local
communities, the concern that the project may not generate sufficient
revenues to cover project costs, the effect of project activities and
wildfire on late seral (old-growth) habitat conditions, the deterioration
of air quality from smoke and project-generated dust, impacts to cultural
(heritage) resources from project activities or from wildfire, the effects
of herbicide use, the threats to meadows by lodgepole pine encroachment and
by wildfire, and the biological, physical, and socioeconomic effects of
constructing, maintaining, and decommissioning roads. Four alternatives,
including a No Action Alternative (Alternative 1), are considered in this
draft EIS. Alternative 2 would involve logging by understory thinning on
approximately 180 acres and follow-up fuels reduction immediately around
public use developments and public use areas using ground-based equipment.
Alternative 3 (the proposed action and the preferred alternative) would
involve logging by understory thinning on approximately 2,200 acres and
follow-up fuels reduction around public use developments and public use
areas and other selected areas using ground-based equipment. The logging
would involve tractor thinning of plantations on 267 acres to generate
410,000 board-feet of timber, helicopter thinning of 654 acres of natural
stands to generate 3.37 million board-feet (MMBF) of timber, and tractor
logging on 1,981 acres to generate 10.8 MMBF of timber, for a total of
2,902 acres of logging to generate 14.5 MMBF. Total biomass removed from
natural plantations would amount to 39,525 tons, representing 15 tons per
acre. The plan would require the construction of 2.2 miles of road and the
reconstruction of 18.2 miles of existing road. Post-logging activities
would include machine piling of slash on 449 acres, logging-related
prescribed burns on 2,453 acres, non-logging-related prescribed burns on
340 acres, planting on 180 acres, and herbicide application on 180 acres.
Alternative 4 would involve logging by understory thinning on approximately
2,900 acres and follow-up fuels reduction around public use developments
and public use areas and other selected areas using ground-based and
helicopter equipment. Plan implementation could begin in late 2000 or 2001.
The estimated cost of plan implementation is $1.88 million, while the
estimated receipts from the timber sale is $2.25 million. POSITIVE IMPACTS:
The plan would directly reduce the threat of stand-destroying fires,
protect improvements, decrease the susceptibility of timber stands to
insect and disease attack, and promote general forest health. Indirect
benefits to wildlife, watershed, recreation values, and commodity
production would also be achieved due to the reduced likelihood of
widespread tree mortality caused by wildfire or insects. NEGATIVE IMPACTS:
Road construction and timber logging activities would result in short-term
erosion and sedimentation of receiving waters. Incidental removal of
non-target vegetation would inevitably result. Losses of individuals of
three sensitive plant species could occur, but these losses would not
affect the status of any population. Smoke from prescribed burning and dust
from road construction would adversely affect air quality temporarily. The
use of ground-based logging equipment would involve some risk of accidental
forest fire. LEGAL MANDATES: National Forest Management Act of 1976 (16
U.S.C. 1600 et seq.).

Solution of forest health problems with prescribed fire: are forest
productivity and wildlife at risk?
Tiedemann, AR*; O. Klemmedson, J; Bull, EL Forest Ecology and Management
[For. Ecol. Manage.]. no. 1-3, pp. 1-18. 1 Mar 2000. Advanced forest
succession and associated accumulations of forest biomass in the Blue
Mountains of Oregon and Washington and Intermountain area have led to
increased vulnerability of these forests to insects, diseases, and
wildfire. One proposed solution is large-scale conversion of these forests
to seral conditions that emulate those assumed to exist before European
settlement: open-spaced stands (ca. 50 trees per ha), consisting primarily
of ponderosa pine (Pinus ponderosa Laws.) and western larch (Larix
occidentalis Nutt.). We question how well presettlement forest conditions
are understood and the feasibility and desirability of conversion to a
seral state that represents those conditions. Current and future
expectations of forest outputs and values are far different from those at
presettlement times. Emphasis on prescribed fire for achieving and
maintaining this conversion raises questions about how well we understand
fire effects on forest resources and values. We consider here potential
effects of prescribed fire on two key aspects of forest
management--productivity and wildlife. Use of large-scale prescribed fire
presents complex problems with potential long-term effects on forest
resources. Before implementing prescribed fire widely, we need to
understand the range of its effects on all resources and values. Rather
than attempting to convert forests to poorly described and understood
presettlement seral conditions, it would seem prudent to examine present
forest conditions and assess their potential to provide desired resource
outputs and values. Once this is achieved, the full complement of forest
management tools and strategies, including prescribed fire, should be used
to accomplish the desired objectives. We suggest a more conservative
approach until prescribed fire effects are better understood.
