Management

Stewardship Responsibility

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

Total species' range in Montana 381,296 km2 (100% of Montana)
Area predicted to have
some level of suitable habitat		 154,550 km2 (41% 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 29% <1% 7% 22%
State 6% <1% 1% 5%
Local <1% <1% <1% <1%
Conservation Lands/Easements 4% <1% 1% 3%
Private/Tribal/Unknown 59% <1% 13% 46%

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