The Goal of the Montana Native Plant Society’s Important Plant Areas Program is to identify the most important sites for plant conservation across Montana using consistent criteria. An Important Plant Area supports an exceptional population of one or more globally rare plants or an exceptional assemblage of plants rare or threatened in Montana.
Documents linked here include instructions for nominating an area as an important plant area and other completed documents for nominated areas.
Designated Important Plant Areas (Note that the links open nomination forms for these approved areas):
