Foxtail Muhly - Muhlenbergia andina
State Rank Reason (see State Rank above)
Muhlenbergia andina occurs widely scattered in western and south-central Montana. It grows in damp places, but often with well-drained soils. It can be found along streams, in wet meadows and seeps, and around hot springs. The low number of collections in combination with limited habitat and/or specific micro-habitat characteristics indicates it is either rare, declining, or over-looked in floristic surveys. Current data on locations, population sizes, habitat, and threats is greatly needed to better assess its status in Montana.
