Abstract
At each of 1 8 sites, chosen to represent the range of subtropical tra nsitional thicket communities in the Cape, 30 plots, each 1 m2, were l aid out. Species occurrence in different strata was noted, as was the incidence of seedlings and sprouts. Almost all canopy species comprise d multi-stemmed individuals which reproduce vegetatively by the produc tion of rooted sprouts. Most individuals are apparently exceptionally long-lived. There is a relative absence of seedlings of most canopy sp ecies. Notable exceptions are arborescent succulents. There is no rela tion between canopy dominance and numbers of seedling regeneration in the woody taxa. These findings are discussed in terms of stability of thicket.
