Author: Aho, Paul E.;

Date: 1971

Publication Series: Research Paper (RP)

Description: A total of 292 Engelmann spruce were dissected and examined for decay and other defects in seven areas in the Blue Mountains of southeastern Washington and northeastern Oregon. Decay on a cubic-foot basis was 3.3 percent for pole trees and 5.4 percent for sawtimber. Defect loss in sawtimber spruce amounted to nearly 12 percent of the gross merchantable board-foot volume. Decay varied among study areas and could not be explained on the basis of age differences.

Keywords: decay fungi (wood), defect indicators (wood quality), fungi (forest damage)
