D.J. Parsons P.W. Rundel T.J. Stohlgren 1984 In the low elevation chaparral areas of Sequoia National Park, California, pure stands of chamise (<i>Adenostoma fasciculatum</i>) are periodically rejuvenated by fire. Mature stands showed considerable variability in density and total biomass even though a positive correlation exists between the two. Mature stands showed a preponderance of individuals in the smaller size classes (inverse-J shape distribution). Dead shrubs found in mature stands also tended to be in the smaller size classes. This relatively high mortality of small individuals is important to post-fire stand development. In addition, resprout and seedling biomass one year after fire both showed inverse-J shaped size-class structures. A positive correlation existed between the preburn basal area of a shrub and its first year resprout biomass. Shrub biomass and distance to nearest neighbor were poorly correlated. A significant correlation existed between stand density and a stand's variance-to-mean ratio, indicating a trend toward more regular spacing as density increases. Pre-burn and fire-induced mortality tended to move the stand towards a more clumped distribution. Seedlings replaced dead individuals after a fire and thus restored regular spacing. application/pdf 10.1007/BF00377549 en Springer-Verlag Population structure of <i>Adenostoma fasciculatum</i> in mature stands of chamise chaparral in the southern Sierra Nevada, California article
