J.W. Sewall Company report on spruce-fir resource in the state of Maine

The spruce/fir resource appears to have a healthy starting inventory which was roughly in balance between growth and drain over the last five-year inventory cycle. Modeling shows that there is an opportunity over the next twenty years to significantly increase the harvest levels of spruce/fir while still maintaining current levels of total spruce/fir standing inventory. In previous runs of the same model, we demonstrate that spruce/fir standing inventory would build significantly if the harvest levels remained at or below the average levels harvested over the last three years
