Threats to sagebrush habitats are many, varied, and now manifesting over vast areas. This book describes methods and example applications to identify and map these threats to sagebrush habitats for benefit of wide array of associated species of conservation concern. Knowledge gained from this work provides an essential foundation for land-use planning and research in the sagebrush ecosystem of western North America. In that context, Habitat Threats in the Sagebrush Ecosystem is a "must-read" for scientists, land managers, and public users of the sagebrush ecosystem.
