Purshia mexicana var. There are conflicting reports on fire's effect on Stansbury cliffrose. Stansbury cliffrose appears to be a weak sprouter that is generally killed by severe fire.
Cool fires promote some resprouting, especially if green foliage remains.
Spring burning with high fuel moisture and soil moisture conditions increase the likelihood of sprouting. Thirteen to fifteen years after a crown fire in pinyon-juniper in Grand Canyon National Park, Stansbury cliffrose was observed in unburned areas, but few plants were present in burned areas. In Death Valley National Monument, Stansbury cliffrose density following a lightning-ignited fire in creosotebush ranged from five to eight plants per square meter. Since Stansbury cliffrose's sprouting ability is apparently variable, fire probably should not be used on this species unless postfire sprouting ability of the population under consideration has been confirmed. Fire used on sprouting Stansbury cliffrose should be low severity surface fire since the dormant buds of Stansbury cliffrose root crowns are apparently killed by severe, and possibly moderate-severity, fire.
