PEREIRA, Eder Miguel; IMANA-ENCINAS, José  and  VALERIA REZENDE, Alba. Evaluation of simplified procedures for quantifying wood volume in a plantation of pine. Colomb. for. [online]. 2012, vol.15, n.1, pp.131-138. ISSN 0120-0739.

Quantification of wood volume in forests stands is necessary for forest management of plantations particularly with respect to the timber trade. Traditional sampling methods used in forest inventories are onerous and costly. Development of rapid, cheap and precise methods which facilitate the corresponding volumetric quantification are desirable. It was compared four sampling methods for determining wood volume in a Pinus plantation. Three of those methods are based exclusively on diameter measurement, whereas the fourth is based on wood volume. Eight randomly located 600 m² plots were used where each method was applied to determine the wood volume per hectare. There were no significant differences in methods for determining wood volume with a permitted maximum error of 10%, and a significance level of α = 0.05. All methods provided reliable estimations of wood volume per unit area, although the Hohenadl diameter method performed slightly better.
