Diameter at breast height (DBH; n = 4127 individuals) for A different levels of forest-use intensity and for B eight sites along the elevation gradient. Vertical axis shows tree diameter at breast height (DBH) on a logarithmic scale. Forest-use intensity levels are old-growth forest (OF), degraded forest (DF) and secondary forest (SF). Boxes are second and third quartile, whiskers upper and lower quartile and horizontal lines indicate mean values.
