SPECIES: Purshia glandulosa | Desert Bitterbrush


Desert bitterbrush recovers from fire by sprouting from undamaged root crowns below the soil surface and by establishing from seeds cached by rodents [6,7,8,28,45].

Fire regimes of the California singleleaf pinyon-California juniper woodlands in which desert bitterbrush appears are dominated by long-interval canopy fires and slow recovery [44]. Fires in desert bitterbrush habitats probably were infrequent, since fuel in sagebrush-bitterbrush and juniper-bitterbrush communities tends to be light. In decadent stands, extremely dry and windy conditions can cause a severe fire [32].

To learn more about the fire regimes in communities in which desert bitterbrush appears, refer to the FEIS summary for associated species, such as big basin sagebrush, redberry juniper (Juniperus erythrocarpa), Gambel oak, Joshua tree, singleleaf pinyon, and California juniper, under "FIRE ECOLOGY OR ADAPTATIONS."


Tall shrub, adventitious-bud root crown
Small shrub, adventitious bud/root crown
Ground residual colonizer (on-site, initial community)
Initial-offsite colonizer (off-site, initial community)
