COSEWIC Assessment Summary and Status Report: Coast Manroot Marah oreganus
Assessment Summary – November 2009
Reason for designation
A long–lived perennial vine occurring at only three widely separated locations in southeastern Vancouver Island and adjacent Gulf Islands. Fewer than 20 mature plants remain with no evidence of seedling production. Losses of habitat, populations and mature individuals are projected in its Canadian range. Main threats are development of the few known sites, alien species and chance events affecting the handful of remaining individuals.
Designated Endangered in November 2009.
