Cliff paintbrush is currently listed as Threatened under the Species at Risk Act and is known in Canada to be restricted to 15 populations in southwestern British Columbia including two historic records ? one from the Coast Mountains and one from the Chilliwack River drainage of the Cascades Mountain Range. In 2005, the number of individuals in the province was estimated at fewer than 250 plants. Cliff paintbrush also occurs in Washington and Oregon, where it is more common and widespread. Cliff paintbrush is a short, herbaceous perennial that occurs in rock crevices; on rocky ridges and slopes, talus, and scree at high elevations in the subalpine to primarily alpine vegetation zones. The plant is likely a facultative parasite, and likely on different host species. Cliff paintbrush is believed to be pollinated by hummingbirds and bees. Reproduction is solely by seeds, which are likely dispersed by wind, birds, and small mammals. Potential threats to this species include resource extraction, recreational use, and climate change.
