Density-size Dynamics of Trees Simulated by a One-sided Competition Multi-species Model of Rain Forest Stands

Stand development processes from various initial densities were simulated employing a one-sided competition model of the size structure dynamics of trees in which the size growth rate and the probability of survival of a tree are linearly depressed by the cumulative basal area of trees in larger size classes. All model functions and parameters were derived from permanent plot censuses in a warm-temperate rain forest in southern Japan. The simulated tree density-mean tree size trajectories using species-averaged parameters were similar to those previously reported for even-aged monocultures
