The damage to residual trees following a partial cutting was studied in nine spruce-fir stands and one hemlock stand in Maine with densities ranging from 800-4400 trees, 1 inch and up in dbh, per acre. Three cutting methods, shortwood, tree-length, and full-tree were used within each stand, removing 40 percent of the biomass. In two of the stands 9 additional plots were set up in which 20, 60, and 80 percent of the biomass was removed using each cutting method. Cutting was done with chainsaws and extraction from stump to trailside was performed with a winch.
