HABITAT TYPES AND PLANT COMMUNITIES:


Desert bitterbrush is found in several semi-arid shrub types throughout its range, including blackbrush (Coleogyne ramosissima), Joshua tree (Yucca brevifolia), chaparral, and singleleaf pinyon (Pinus monophylla)-California juniper (Juniperus californica) woodlands [8,15,47].

In California, desert bitterbrush is commonly found with basin big sagebrush Artemisia tridentata ssp. tridentata), blackbrush, singleleaf pinyon, and California juniper. It also occurs with Joshua tree, creosote bush (Larrea tridentata), honey mesquite (Prosopis glandulosa), Stansbury cliffrose, and Great Basin bristlecone pine (Pinus longaeva). Shrubs often form more than 90% of the cover in desert bitterbrush stands. Perennial grasses are a minor element, and forbs are even less important [28].

In Nevada, desert bitterbrush is a component of the mountain brush community with snowberry (Symphoricarpos spp.), antelope bitterbrush, Stansbury cliffrose, mountain-mahogany (Cercocarpus spp.), Gambel oak (Quercus gambelii), juneberry (Amelanchier pallida), wild crab apple (Peraphyllum ramosissima), and chokecherry (P. virginiana).

In the San Gabriel Mountains of California, desert bitterbrush occurs in the sagebrush scrub community with basin big sagebrush, Joshua tree, single-leaf pinyon, rubber rabbitbrush (Chrysothamnus nauseosus), spiny horsebrush (Tetradymia spinosa), Nevada broomsage (Lepidospartum latisquamum), beavertail pricklypear (Opuntia basilaris), shadscale (Atriplex confertifolia), and fourwing saltbush (A. canescens) [14].
