Seedlings and crown sprouted plants of Adenostoma fasciculatum H. and A. were studied at various times after fires in the chaparral near the Newhall-Castaic area in California. In contrast to certain reports in which it was stated that chamise seedlings seldom contribute to mature chaparral cover, eighty-six percent of all chamise plants were seedlings, fourteen percent crown sprouts. Mean seedling height was significantly shorter than the crown sprout height six years after fire but not at eight or nine years postfire. Another area which burned twice in four years had two types of crown sprouted plants but no seedlings following the second fire. Differences in numbers of taxa in certain genera are discussed in relation to reproductive strategies following fire.
