An over-mature Douglas-fir/western larch stand on the Coram Experimental Forest in Montana averaged about 7,300 ft3/acre (511 rn3/ha) of wood over 3 inches (7.62 cm) in diameter, and an additional 57 tons/acre (128/ha) of fine material, before harvest. After logging, using three different cutting methods and four different levels of utilization, wood residues ranged from 600 ft 3/acre (43 m3/ha) under intensive utilization to over 3,500 ft3/acre (245 m3/ha) where only saw logs were removed. Fine residues increased under all treatments.
