Abstract:

Point-model based sampling is described for timber inventory. Point-model based sampling is an improvement on point-3P sampling because the number of sample trees selected for detailed dendrometry is completely controlled. Field studies indicate that estimates derived from it are comparable to those from point-3P sampling. However, serious errors in estimates could arise from point-model based sampling if the linear model relating volume to D²H is incorrect. South. J. Appl. For. 15(3):109-113.
