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.
Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Southern Journal of Applied Forestry covers an area from Virginia and Kentucky south to as far west as Oklahoma and east Texas.
