Handbook for predicting residue weights of Pacific Northwest conifers.
Abstract
Procedures are given forest estimating weights of potential residue from Douglas- fir and western hemlock created by forest management activities west of the summit of the Cascade Range. Preliminary estimates are given for six other species. The weight tables are in pounds per tree and pounds per square foot of basal area for a 6- or 8- inch unmerchantable tip. The estimates are also separated into material of: <3-inch and - >3-inch diameter and total weight. The tabular weights include foliage, live and dead branchwood, and unmerchantable tip.
