Protection Balsamorhiza deltoidea has been globally ranked by The Nature Conservancy of the United States as "G5," or "common to very common with an exis- tence that has been demonstrated to be secure and essentially ineradicable under present ; The British Columbia Conservation Data Centre has ranked this species as S2 and placed it on the Ministry of Environment, Lands and Parks Red list (Douglas et al 1998a). The S2 rank indicates that the plant is "imperiled because of rarity (typically 6-20 extant occurrences or few remaining individuals) or because of some factor(s) making it vulnerable to extirpation or extinction". Balsamorhiza deltoidea has a national rank in Canada of N2. There is no specific legislation for the protection of rare and endangered vascular plants in British Columbia. Some populations of Balsamorhiza del- toidea are protected to a certain extent by their loca- tion on public property. Of all the B. deltoidea sites known in British Columbia, those located on Mount Tzuhalem receive the greatest degree of protection. 51 N VANCOUVER ISLAND 50N •49n 128 W 127vy-' 126W 125 W 124,W / 123 W.
