a formula, namely, D is equal to D1- (K (130-H)), so as to evaluate the DBH (diameter at breast height) value of the cut timber, and then searches in the one-variable volume table of standing timber in each area based on the DBH value so as to evaluate the cut timber volume....
Tree measurements from field plots in China, Germany, Poland, Myanmar and South Africa were analyzed to evaluate the feasibility and usefulness of the structural diversity index. The species and diameter at breast height (DBH) of every tree with a DBH greater than 5 cm were recorded in these ...
