Book Description

Excerpt from Logging Residue in Southeast Alaska Detailed information on logging residues in southeast Alaska is provided as input to economic and technical assessments of its use for products or site amenities. Two types of information are presented. Ratios are presented that can be used to gener ate an estimate, based on volume or acres harvested, of the cubic-foot volume of residue for any particular area of southeast Alaska. Separate ratios are given for live and dead or cull material, and for net and gross volume. Tables display per-acre residue volume by various characteristics that might affect either use or disposition. These tables show net or gross volume, or both, by diameter and length classes, by origin, by percentage of soundness, by degree of slopes and distance to roads, and by number of pieces of residue per acre. Keywords: Southeast Alaska, logging residue, slash, residue estimation, fuel wood, residue management. A large volume of woody biomass has traditionally remained on site after logging in southeast Alaska. Interest is growing in this material for energy and conventional products, as well as for its environmental attributes. A great deal of information is needed on the volume and characteristics of residue to adequately address these options. Existing sources were out of date and did not provide the information needed to make site-specific assessments for southeast Alaska. This study provides the capability to estimate the volume and characteristics of logging residue throughout southeast Alaska. This study had two objectives. The first was to develop ratios for use in estimating the volume of logging residue for any area in southeast Alaska. These ratios relate the quantity of residue to timber harvest volume or harvested acres. Study results show, for example. An average net volume of logging residue (wood only) of 79 to 109 cubic feet per thousand board feet of harvest and an average gross volume ranging from 125 to 158 cubic feet per thousand board feet of harvest. The second objective was to provide data characterizing logging residue in ways that might affect its utilization for various products or its management for environmental considerations.
