Topics covered for bitterbrush include description, distribution, habitat requirements, wildlife value, establishment, maintenance, and cautions and limitations. Antelope bitterbrush is a semievergreen native shrub that occurs predominantly on well drained hillsides and slopes in the West. It is considered one of the most important western browse species for big game, especially mule deer Odocoileus hemionus, and plants are also used for food and cover by a variety of other game and nongame wildlife. Diagnostic characteristics of bitterbrush are described, and ecotypic variation is discussed. Habitat requirements, including soil and moisture preferences, are described. Food and cover value is discussed for several big game animals, and wildlife species known to use bitterbrush are listed. Guidelines are provided for site selection, site preparation, propagule selection and treatment, planting methods, and maintenance of bitterbrush stands.
