Common (Translated Scientific) Name: Red Willow - Arroyo Willow / Mule-fat Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is only known from the Santa Monica Mountains region. This woodland association occurs on gentle to somewhat steep slopes with little influence of aspect (being flat to variable in nature) and at elevations between 73 and 303 m. It is dominated by Salix laevigata in the overstory tree layer and Salix lasiolepis in the understory tree layer. It has an open cover of Baccharis salicifolia in the understory shrub layer and an open cover of various grasses and forbs in the herbaceous layer.

Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form an open to intermittent tree layer (14-50%, mean 25.1%) with hardwoods at 5-10 m tall, a sparse to open shrub layer (4-28%, mean 14.3%) at 0-5 m tall, and a sparse to open herbaceous layer (2-18%, mean 9.9%) at 0-1 m tall. Total vegetation cover is 42-51%; mean cover is 47.3%. In this association, the overstory tree layer is dominated by Salix laevigata. Salix lasiolepis is dominant in the understory tree layer. The shrub layer is sparse to open and is dominated by Baccharis salicifolia. The herbaceous layer is diverse and often includes Hirschfeldia incana and Artemisia douglasiana. Other herbs occasionally include Typha sp., Piptatherum miliaceum, Carduus pycnocephalus, and Foeniculum vulgare.
