Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form a sparse to intermittent tree layer (5-36%, mean 20.3%) with hardwoods at 2-10 m tall, a sparse to intermittent shrub layer (5-47%, mean 28.2%) at 0-5 m tall, and a sparse to open herbaceous layer (0-30%, mean 7.5%) at 0-2 m tall. Total vegetation cover is 40-70%; mean cover is 53.5%. In this association, the tree layer is dominated by Juglans californica. Quercus agrifolia and Platanus racemosa are occasionally included in this layer. The shrub layer is sparse to intermittent and often includes Artemisia californica. Frequently, Salvia leucophylla, Toxicodendron diversilobum, and Malosma laurina are also included. A variety of other shrubs is also present at lower cover. The herbaceous layer is diverse and is dominated by Leymus condensatus. Other herbs include Centaurea melitensis, Hirschfeldia incana, and a variety of native and non-native grasses and forbs.
