Mixed desert shrub is a plant community, or vegetation type, found in the Colorado Plateau and Canyonlands region of the southwestern United States. It is supported by a range of overlapping and intergrading soil types. Characteristic dominant plant species include rubber rabbitbrush (Chrysothamnus nauseosus), fourwinged saltbrush (Atriplex canescens), blackbrush (Coleogyne ramosissima), and dwarf mountain mahogany (Cercocarpus intricatus). It is generally located at the elevation belt (zone) above sand desert shrub and below cool desert shrub.
