Assessment of Logging Residue in Montana : Final Report.
This study addresses the need for a data base with the capability to provide information on residue volume and characteristics for any location in Montana. Gaps in existing data sources made clear the need for development of a logging residue data base for Montana. The first objective of this study was to develop analytical tools for estimating the volume of logging residue for any uniquely defined supply zone in Montana. Ratios developed in this study relate residue volume to both timber harvest volume and acreage. One ratio gives the cubic foot volume of residues associated with the harvest of 1000 board feet of timber (CF/MBF). The other ratio provides an estimate of cubic foot volume of residue per acre harvested (CF/AC). The second objective was to describe and classify residue by characteristics that affect utilization. Characterization of residue was by: gross and net volume of logging residue by diameter and length, for live and dead or cull material; number of pieces of residue per acre, by diameter and length; volume of residue by percent sound (chippability), in cubic feet per acre; accessibility of residue on cutover areas, by slope and distance to road; and volume by product potential class. 15 refs., 7 figs., 12 tabs.
