Idaho’s tracked herds include several cross-border elk populations shared with Nevada — the Bruneau-Diamond Desert and Owyhee Desert herds — that range across thousands of square miles of sagebrush country. This map shows every USGS-mapped big-game migration corridor in Idaho — 3 herd units, 0 GPS-collared animals, and 0 tracked migration segments, recorded between None and None.

Across the West, the biggest threats to big-game migrations are not the things that kill individual animals — they’re the things that fragment the corridor itself. Energy development, road crossings, fences and subdivision of winter range have all been documented as drivers of corridor loss in this dataset. State wildlife agencies, the USGS Corridor Mapping Team, and conservation NGOs are now using maps like this one to guide decisions about where to build wildlife crossings, where to replace woven-wire fences, and where to prioritise conservation easements on private winter range.
