Rank Reasons
Douglasia conservatorum occurs in the western United States, where it is endemic to the Coeur d’Alene Mountains along the Idaho and Montana border. There is a single known occurrence with a population size of 500 plants. The species occurs on Forest Service Land. Threats include climate change and off road vehicle.
Range Extent Comments
Douglasia conservatorum is endemic to the western United States where it is endemic to the Coeur d’Alene Mountains along the Idaho (Shoshone County) and Montana (Sanders County) border (Björk 2010).
Occurrences Comments
The only known occurrence is on Bloom Peak(Björk 2010).
Threat Impact Comments
Although the habitat is remote, this species is threatened by off-road vehicles, which was recorded as damaging about 5% of the plants in 2008 (Björk 2010). Climate change is likely a threat, as this is a subalpine species occurring at the peak of the mountain.
Ecology & Habitat

Habitat

This species grows in gravelly substrates (Precambrian siltite) amongst other other short-statured subalpine vegetation along a ridgeline that is exposed to high winds and intense sunlight (Böjrk 2010).
