Biomass Distribution in Western Hemlock, Douglas-Fir and Western Redcedar.
This report presents results from a study characterizing the weight and volume of trees from overstocked (doghair) mixed conifer stands of Douglas-fir (Pseudotsuga menziesii), western hemlock (Tsuga heterophylla) and western redcedar (Thuja plicata) located on the Quilcene Ranger District, Olympic National Forest. There are approximately 20,000 acres classed as doghair on the Quilcene District. In order to evaluate their harvesting and utilization potential accurate estimates of volume and weight of entire trees and stands are needed. The objective of this study was to characterize the biomass of the three major tree species located in overstocked stands by providing estimators to predict the green and dry weight of the total tree, as well as separate predictions for the components of stem and crown. Additional objectives included estimates for the weight of the 'standing dead', the weight of the dead material on the forest floor, and estimators to predict the cubic volume of the wood and bark in the stems. 11 refs., 9 figs., 15 tabs.
