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.
