Logging residue yield equations from West Virginia timber harvests.

Line intersect and fixed plot sampling methodologies were used to measure both logging residues and overstory structural characteristics on 101 harvested stands in West Virginia. Equations were developed for predicting total and species-specific postharvest residue volume based on two independent variables, average dbh, and basal area of harvested trees. Finally, yield tables were developed that present expected postharvest residue volumes.
