Abstract

Regression equations are presented for estimating biomass of five western hardwoods: red alder (Alnus rubra Bong.), giant chinkapin (Castanopsis chrysophylla (Dougl.) A. DC.), bigleaf maple (Acer macrophyllum Pursh), Pacific madrone (Arbutus menziesii Pursh), and tanoak (Lithocarpus densiflorus (Hook. & Arn.) Rehd.). Estimators are given for total crown biomass, cumulative proportions for separating crown weight into foliage and four timelag fuel diameter classes, bark weight, and bole volume (inside bark) to any specified top diameter. With one exception, the equations use diameter at breast height as the only independent variable.
