I studied mechanisms and implications of land use impacts on raptors on the Missouri Coteau of northwestern North Dakota by (1) tracing change during the past century in raptor species composition and habitat on the 108-km2 Lostwood National Wildlife Refuge (LNWR), (2) assessing current (1981-90) population stability, annual reproductive success, and habitat relationships of raptors on LNWR and comparative species' nesting densities on an adjacent area of different land use, and (3) determining prey needs of common, large (>700 g)raptor species on LNWR and prey use in relation to habitat on an area of contemporary la
