Pulping of Budworm-Killed Balsam Fir (1982)

Problem Addressed: Spruce budworm-killed balsam fir
Goal(s)/Objective(s): Compare properties of the dead balsam fir to those of live, healthy fir.
Key Findings: Spruce budworm-killed trees had significantly decreased moisture contents; lower specific gravity and bark content, and smaller sized chips as a function of time-since-death.
