Figure 4

Red–Green–Blue (RGB) colour composites of leaf mass per area (LMA, red), leaf carbon concentration (C, green) and leaf nitrogen concentration (N, blue) of Québec forests with a canopy cover above 30%. Zone A corresponds to the location of the Laurentide Wildlife Reserve, while zone B indicates Mont Mégantic. In the captions, from top left, clockwise: forest stand type³⁶, elevation⁴⁰, RGB composite of canopy traits, and dominant species⁴¹ over Mont Mégantic. In black, areas where canopy traits were not estimated due to low canopy cover or unavailable data.
