Abstract

The aim of this study is to scrutinise whether a dynamic equilibrium model based on sustainability of the demography is valid for pure beech plenter forests. Broad-leaved trees in general, and beech in particular react differently to individualisation and to shade than conifers, because of differences in space occupancy and their reaction to shade. Therefore application of the plenter system (or selection system) presents other constraints than for conifers forests. Sustainability must be assessed at stand level, because the plenter system functions without cover interruption and so needs continuous recruitment growing from the stand bottom up. The algorithm used for determination of demographic equilibrium depends on knowledge of the recru...
