ICP Forests database structure and links with dataset presented in this paper. GPL, General Plot Location and information; DWD, dead material lying on the ground; THT, Tree Top and crown base Height; DBH, tree diameter, status, and composition; DWT, deadwood trees (standing dead material). DBH and THT have been used to calculate volume of standing trees, DWD to calculate volume of material lying on the ground. See the text for details
