[fs.usda.gov] Threats: Threats Many populations exhibit severe damage from cattle grazing. Populations are threatened by road widening and grading. Other threats listed include trash dumping, erosion and trampling. Fire suppression or inappropriate timing of fires would also impact these plants by precluding growth, reproduction, and replenishment of its underground seed banks. (contributed by Mary Ann Machi)

[explorer.natureserve.org] Conservation status: Endemic to Santa Barbara, San Luis Obispo and San Bernardino counties, California. Currently known from only about 11 or fewer extant populations. There is one population with about 600 plants, but the rest have been reported as containing only 1-25 plants. Many populations exhibit severe damage from cattle grazing. Urbanization and associated road widening and road maintenance are also threats. No populations are currently in permanent protection. This is a fire follower and, after decades of fire prevention in southern California, this plant is declining. (contributed by Mary Ann Machi)
