Allometric biomass and dendrometric dataset for four subtropical tree taxa (Cunninghamia, Pinus, Populus, Quercus) in Hunan, China

This dataset contains destructive sampling data used to develop compatible biomass models and analyze allometric scaling strategies for four major tree taxa in Hunan Province, subtropical China. The dataset includes measurements of diameter at breast height (DBH), tree height, and the dry biomass of four aboveground components (stem wood, stem bark, branches, and leaves) for 498 individual trees.
