Comments:Mullally (1992) describes woodlands dominated by California walnut and other woodlands where California walnut is a secondary component. The understories are composed of coastal scrub, chaparral, and non-native grass species. California walnut is rare (a CNPS List 4 plant) (Skinner & Pavlik 1994).
Plot based descriptions:Keeley (1990) reports tree density and crown cover for three stands in SoCo.
