Description: Data collected since the 1950s from commercial treatments on more than 400 acres in the Penobscot Experimental Forest in Maine indicate a high mortality rate of 520 percent of net growth in the woodland preserve where timber is not harvested, a low mortality rate of 16 percent of net growth under the selection system. As the intensity of silvicultural treatment increased, periodic net annual growth increased from 10 cubic feet per acre (0.7 m³/ha) in the woodland preserve to 56 cubic feet per acre (3.9 m³/ha) under the selection system.
