Regrowth of two important chaparral shrubs (Adenostoma fasciculatum H. & A.—chamise, and Ceanothus crassifolius— buck brush) has been studied after five different fires in the vicinity of Newhall, California. It is clear that chamise seedlings are regularly important in regeneration of chamise populations after fire, even though preexisting chamise plants can resprout from their crowns. It is found, on the other hand, that populations of buck brush frequently do not regenerate after fire despite the great buck brush potential for seedling growth. This problem is briefly examined although no immediate explanation is apparent.
