This accessible field guide identifies and describes native California tree species and most common shrubs in text complemented by more than 200 line drawings, 300 range maps, and 40 color photos.

Southern California, with its valleys, high mountains and deserts, is exceptionally rich in native shrubs. Within this richly diversified area grow approximately 400 kinds of shrubs, and the great majority of them are mentioned in this book, which includes both color and black and white illustrations.

A two-stage shelterwood cutting, at 12 trees per acre, with site preparation, enhanced seedfall, regeneration, and residual growth at the Challenge Experimental Forest, north central California. Shelterwood trees produced 9.2 times more seed than trees in the control. Ponderosa pine regeneration numbered about 3700 seedlings per acre (9139 per ha) and tolerant conifers 600 seedlings (1482 per ha) after 5 years. Hardwood seedlings and sprouts also were abundant. Basal area growth rates for all species in nearly all diameter classes were greater in the shelterwood than in the control. The shelterwood cutting method is recommended for use in young-growth, mixed-conifer stands.
