Effect of harvesting intensity on stand production and heterogeneity at different time scales, in the case of individual selection cutting (group size = 0 m2). Here are presented nine indicators describing the results obtained for the harvesting intensity experiment in the case of individual selection cutting (Exp2). Each plot gives the relation between the Harvesting proportion parameter modalities (x axis) and one stand indicator (y axis), as observed after 50 years (squares), 100 years (circles), and 150 years (triangles), compared to initial values (dotted lines). a and b give information about living stock, c about regeneration, d to g about heterogeneity, and h and i about wood production. Each point represents the mean value calculated on the five simulations done for the given silvicultural modality, and error bars represents one standard deviation
