Fig. 6

Simulated silver fir evolution from 2010 to 2050 and to 2090 on the northern slope of mount Ventoux (south-east of France). On these 3D-diagrams, Abies alba stand basal area is indicated by the shade level (white: no fir); other species are not shown. The larger white areas near the mountain crest represent stone fields where forest is unlikely to progress; they are not taken into account in the simulation. The whole scene covers ca. 8 km × 5 km
