A product ratio calculator for northeastern tree species.

摘要

PRCalc is a stand-alone Microsoft Windows-based program that calculates percent volume of timber products for a given tree list or stand table and product specifications. The program uses Honer's merchantable volume ratios approach. It can be used to assess stand value and to examine effects of varying dimensional species specifications for timber products. PRCalc develops merchantable ratios for both metric and imperial units. An example is given illustrating the efficiency and applicability of the product ratio approach. The data used in the example were from an extensive volume study in Quebec, Canada.
