A new method is proposed to compute the functional effects of competition for light in plant populations. It is based on the estimation of exposed green leaf area for each individual. For this purpose, each individual in the stand is assigned a disk-shaped zone SP representing its assumed crown projection and competitive neighbours are defined as plants having overlapping disks. We combine the foliage distribution functions of neighbours to compute the probabilities of dominance and thus the… CONTINUE READING
