Abstract
Native tallgrass prairie and wetland habitat in the Prairie Pothole
Region of the United States have declined over the past two centuries.
Bird communities using these habitats have also experienced widespread
declines that are often attributed to severe habitat loss and
fragmentation. We estimated the change, or turnover, in bird populations
in the Eagle Lake Wetland Complex, Iowa, with ongoing grassland
and wetland restoration by linking geographic information system
data and bird surveys in different land cover types (hayland,
pasture, restored grassland, restored wetland and rowcrop agriculture)
during the 1999-2001 breeding seasons. Habitat restoration efforts
primarily converted rowcrop agriculture and pastures into grassland
and wetland habitat. Based on land conversion, abundances of most
species have likely increased in the area, including many species
of management concern. Yet a few species, such as killdeer (Charadrius
vociferus), have probably decreased in abundance. This estimation
approach and these estimates provided a critical first step for
evaluating restoration efforts; however, information on demographic
parameters, such as nesting success, in restored areas is needed
for understanding how restoration ultimately affects bird populations.
