Branched phacelia (Phacelia ramosissima var. ramosissima) is a robust perennial plant restricted to intermountain areas from the southern Okanagan Valley in south-central B.C., south through Washington and Oregon to Nevada and southern California. NatureServe has assigned a status of globally secure to the species. Branched phacelia is assessed as Endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). This designation was assigned because the Canadian populations are geographically restricted and known only from three1 small populations numbering fewer than 1000 plants. The species was listed on Schedule 1 of the federal Species at Risk Act in 2006 as endangered. The Canadian extent of occurrence covers about 5 km2 near Osoyoos, BC, and the three populations known from Canada occupy less than 1 km2. The populations occur on a mix of private and provincial Crown land. Within its range, branched phacelia is restricted to talus slopes in the Bunchgrass and Ponderosa Pine Biogeoclimatic zones. It appears to prefer steep (40-60%) slopes of various aspects, sparsely vegetated with shrubs, forbs, and grasses. Branched phacelia faces threats from habitat loss or degradation due to urban development, mining and mineral exploration, and potential threats of talus removal, recreational activities, and invasive species.
