Effects of initial Basal Area (m2 per ha, left) and Richness (expressed as number of tree species per ha, right) on the production (average basal area increment, m2/ha/year) assessed during the period 1972 to 1997. The lines, calculated by a 0.99 nonlinear percentile regression, represent an estimate of the maximum production for different levels of richness and density
