Abstract

The two native California oaks in the forest zone of California are California black oak (Quercus kelloggii Newb.) and tanoak (Lithocarpus densiflorus [Hook. and Arn.] Rehd.). Both are ancient species with many adaptations to withstand California's Mediterranean climate, but some weaknesses as well. Both sprout vigorously from the root crown and both produce copious amounts of acorns. Sprouting has been the primary reproduction mode of approximately 90 percent of trees in existing stands. Research on oak regeneration and seedling physiology has been limited and sporadic. No major research program has been active for the last decade, although some plantings have been attempted for wildlife and recreation purposes.
