A classified Landsat 5 Thematic Mapper image of Hamilton County, Illinois was edited to include the actual location of all Conservation Reserve Program (CRP) fields as of 1990. We investigated the spatial relationship of CRP fields to other land-use types using geographic information system (GIS) software. We used computer simulation and habitat modeling to evaluate northern bobwhite (Colinus virginianus) habitat quality with and without CRP land. Contribution of CRP fields to habitat quality depended on (1) the amount of CRP land present, (2) its suitability for bobwhite use, (3) the suitability of replaced and remaining cropland for bobwhite use, (4) the luxtaposition of CRP fields with other habitat components, and (5) the composition and quality of existing bobwhite habitat, in particular, the limiting factors
