Skinner and Pavlik (1997) say grazing is a threat, but USFWS (1995) indicated that grazing in the riparian habitat may reduce the competition from other species (this species is spiny and may not be grazed). Oil production is also considered a threat by the California Natural Diversity Database and USFWS (1995). In 2001 the California Native Plant Society indicate that developments, vehicles, groundwater pumping, non-native plants and possibly grazing (CNPS 2001).
