Fig. 2: Altitude of the tree lines in China.
From: Substantial contribution of trees outside forests to above-ground carbon across China
The figure presents the altitudinal distribution of tree lines across China based on high-resolution canopy height maps. a shows the spatial distribution of tree line altitudes across China for elevation over 3000 m. Plots b–g provide examples of tree line distributions in various provinces: b Yunnan, c Sichuan, d Gansu, e Qinghai, f Xinjiang and g Tibet. Note that tree lines at elevations below 3000 m have been masked out.
