Figure 1: (a) Evolution of spatial distributions of Fir tree densities (stems/ha) in the Mont Ventoux landscape. This multispecies site of about 1100 ha is called the reference landscape (only the Fir specie is displayed). Only year 2000 (observed), years 2050 and 2100 (simulated with the CAPSIS based process model) are shown, with the same coordinates and the same logarithmic colour scale. (b) The same landscape with hypothetical random tree densities is plotted for comparison and for visualizing patch boundaries.
