Management

Stewardship Responsibility

Based on the Montana Natural Heritage Program's latest predicted habitat suitability model

Total species' range in Montana 381,165 km2 (100% of Montana)
Area predicted to have
some level of suitable habitat		 139,945 km2 (37% of Montana)

Stewardship responsibility for the predicted area of suitable habitat can be broken down as follows

  Total Suitable Optimal Suitability Moderate Suitability Low Suitability
Federal 20% <1% 8% 12%
State 7% <1% 2% 5%
Local <1% <1% <1% <1%
Conservation Lands/Easements 1% <1% <1% 1%
Private/Tribal/Unknown 71% <1% 15% 56%

See the Habitat Suitability for Biodiversity task in Map Viewer for a more detailed look at stewardship responsibilities within a variety of local jurisdictions.
