Habitat

Stewardship Responsibility

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

Total species' range in Montana	6,766 km²	(2% of Montana)
Area predicted to have some level of suitable habitat	2,031 km²	(<1% 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	88%	3%	36%	49%
State	<1%		<1%	<1%
Local
Conservation Lands/Easements	<1%		<1%	<1%
Private/Tribal/Unknown	10%	<1%	3%	7%

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