A framework for conservation planning was developed to evaluate options for reducing development impacts on Greater Sage-Grouse (Centrocercus urophasianus) in Wyoming, Montana, Colorado, Utah, North Dakota, and South Dakota. Lek-count data (2,336 leks) were used to delineate high-abundance population centers, termed core regions, that contained 25%, 50%, 75%, and 100% of the known breeding population. Sage-grouse abundance varied by state. Wyoming contains 64% of the known sage-grouse population and more active leks than all the other states combined within the study area. Montana contains fewer sage-grouse (24%) than Wyoming, but actions that reduce sagebrush (Artemisia spp.) tillage by providing private landowners incentives to maintain sagebrush-dominated landscapes would provide lasting benefits because core regions in Montana are at comparatively low development risk. Habitat restoration in areas with low risk of development but containing fewer sage-grouse fit into the overall conservation strategy by targeting populations that promote connectivity of core regions.
