BD of tree components as a function of their corresponding diameter (i.e., diameter of each sample) for each tree species (for bark component the stem diameter was used): knot-free stem wood (stem w/o knots; purple), bark (blue), knots (yellow), branch insertions (Br ins; orange), branches without insertion (Br w/o ins; green). The horizontal line is the mean BD measured at breast height while the dotted line represents the Global Wood Density Database value
