Rank ReasonsErigeron flabellifolius occurs in the Absaroka and Beartooth Ranges in southwestern Montana and northwestern Wyoming. In Wyoming, the species is known from eighteen to twenty extant occurrences, nearly all of which are in wilderness areas or high elevation sites with few threats. A large colony is found along the Beartooth Highway in northern Wyoming, but it seems secure despite high human recreation and vehicle traffic. Populations of this plant may be locally abundant.
