Castilleja kaibabensis is endemic to a few large meadow systems on the Kaibab Plateau, north of the North Rim of the Grand Canyon in Coconino County. Recreational activity, grazing, and road construction remain concerns for the management of this species. Castilleja kaibabensis is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
