Greater sage-grouse (Centrocercus urophasianus) is a candidate for listing under the Endangered Species Act because of population and habitat fragmentation coupled with inadequate regulatory mechanisms to control development in critical areas. In addition to the current threats to habitat, each 1 degree celsius increase due to climate change is expected to result in an additional 87,000 km2 of sagebrush (Artemisia spp.) that will be converted to unsuitable habitat for sage-grouse. Thus, the future distribution and composition of sagebrush landscapes is likely to differ greatly from today’s configuration. We conducted a large, multi-objective project to identify: (1) characteristics of habitats required by sage-grouse,...

Habitat and population fragmentation were among the primary factors contributing to the recent U.S. Fish and Wildlife Service decision that listing greater sage-grouse (Centrocercus urophasianus, hereafter sage-grouse) was warranted but currently precluded by higher priority actions. Increasingly, current management is focused on core or priority areas containing the highest densities of breeding birds with little regard to understanding connectivity within and among areas. The most fundamental objective of species conservation is to first identify and subsequently maintain a set of viable and connected populations. Therefore, if management emphasis on core areas is to be successful for long-term conservation, it...
