Plagiobothrys hirtus, the rough popcornflower, is a plant species with only about a dozen reportedly extant occurrences, all within the Umpqua River watershed in Douglas County, Oregon. It is federally listed endangered in the United States of America. In fact P. hirtus is now considered to be one of the top three most endangered vascular plant species in the Northwest. The state of Oregon has ranked this plant as its number one recovery priority due to its high degree of threat as well as its high rating in recovery potential. Its recovery depends on conservation of existing populations as well as reintroduction of new populations in protected and species-appropriate areas.
