Predicting crown weight and bole volume of five western hardwoods. Forest Service general technical report
Technical Report
·
OSTI ID:7243550
Regression equations are presented for estimating biomass of five western hardwoods: red alder (Alnus rubra), giant chinkapin (Castanopsis chrysophylla), big leaf maple (Acer macrophyllum), Pacific madrone (Arbutus memziesii), and tan oak (Lithocarpus densiflorus). 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 equation uses diameter at breast height as the only independent variable.
