Assemblages of breeding birds as indicators of grassland condition Assemblages of breeding birds as indicators of grassland condition
We developed a measure of biological integrity for grasslands (GI) based on the most influential habitat types in the Prairie Pothole Region of North Dakota. GI is based on proportions of habitat types and the relationships of these habitat types to breeding birds. Habitat types were identified by digital aerial photography, verified on the ground, and quantified using GIS. We then...

Effects of management practices on grassland birds: Nelson's Sharp-tailed Sparrow Effects of management practices on grassland birds: Nelson's Sharp-tailed Sparrow
Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated...
