    Description

    Several years ago, old-growth red spruce at high elevations in the Green Mountain National Forest were observed to be dying. Entomologists and pathologists who examined the affected area found no insect or fungus that was obviously causing the deaths. However, many of the dead and dying trees were butt-rotted by the fungus Polyporus borealis. Though it seemed unlikely that butt-rot was the cause of death, a cooperative study was begun by the Northeastern Forest Experiment Station and the Green Mountain National Forest in the spring of 1955 to determine the relationship of heart rots in red spruce to mortality.
