Calculating tree bole surface area for estimating populations of the southern pine beetle (Coleoptera:Scolytidae)

A conoidal frustum model was determined to be a practical and an accurate method for estimating the bole surface area of southern pines. Sample percent bias and absolute bias criteria indicated clear superiority over a nonlinear regression model that has been widely applied as a tree geometry model...
