Maps & Data

2014 Bighorn Sheep Occupied Habitat and updated 2016 Domestic Sheep Grazing Allotments GIS Layers

The maps provided below reflect occupied bighorn sheep habitat and domestic sheep grazing allotments within Forest Service (FS), Bureau of Land Management (BLM). Bighorn sheep habitat information was provided by individual state wildlife management agencies. Each state defined and delineated their bighorn sheep habitat differently.  Each state's bighorn sheep habitat definition, is located on each respective State map.  The grazing layers were supplied by the associated federal land management agency.  Please note: Bighorn sheep habitat definitions differ between states.

The mapping project was accomplished through the cooperative efforts of the FS, BLM and WSWG.
