Abstract

A description of stand development is presented which incorporates several ecological concepts, including: full-site occupancy; self-thinning; and the relation between the number and average size of plants in the population. Each of these concepts is integrated by a general size-density model. It is suggested that stands which are undergoing self-thinning are those which have achieved an upper limit in the amount of foliage supported. It is postulated that the predictable size-density relations in self-thinning populations can be explained on the basis of regulation and redistribution of a fixed amount of foliage among a declining number of larger individuals.
