A Guide to Using Regression Equations for Estimating Tree Biomass

Abstract

Abstract Tree biomass is most commonly estimated using regressions of green or dry weight to tree dimensions. Rarely is it feasible for managers to develop their own predictive equations, so they must rely on published regressions and weight tables developed from those regressions. A guide is presented that will help each manager select the most appropriate equation available for a given situation. We also provide common regression models currently in use, statistics for comparing published equations, and practical examples of their application. Sources of weight tables and biomass regressions for northern species are also noted. North. J. Appl. For. 5:15-22, March 1988.
