It occurs at lower elevations in mountain ranges of Trans-Pecos Texas and in central and southern California, along sandy watercourses and dry arroyos.

Common (Translated Scientific) Name: Mule-fat Wet Shrubland Alliance

Colloquial Name: Mule-fat Wet Shrubland

Hierarchy Level:  Alliance

Type Concept: This alliance includes riparian shrublands dominated by Baccharis salicifolia. Salix gooddingii may be an emergent tree at low cover in some stands. Other associated species can include shrubs such as Artemisia californica, Baccharis emoryi, Baccharis neglecta, Baccharis pilularis, Malosma laurina, Nicotiana glauca, Pluchea sericea, Prosopis glandulosa var. glandulosa, Rubus spp., Salix exigua, Salix lasiolepis, and Sambucus nigra ssp. canadensis.
