Localized log–log regression equations were developed for young red alder (Alnusrubra Bong.) and Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) to predict branch and leaf dry weights from branch diameters, and leaf and branch dry weights (predicted from branch diameters), bole volumes and weights, and tree heights from stump and breast-height diameters. Correlation coefficients were generally greater than 0.9. These equations will be useful for similar sites in estimating aboveground biomass at precommercial thinning, fuel loadings, nutrient cycling, and productivity.
