Fig. 4

Mean tree height in mixed stands observed in the ORPHEE experiment (right panels) and simulated by ForCEEPS (left panels), at the high (upper panels: 1500 or 1250 stems/ha) and low (lower panels: 750 or 833 stems/ha) density. For each year, each density, and each species, the difference was not significant between observations and simulations, except for pines at the last year
