Lake States Aspen Report No. 11
U.S. Dept. of Agriculture, Forest Service, Lake States Forest Experiment Station
During recent years, aspen has been used in the Lake States region for a number of products. The war years in particular showed a marked increase in the use of aspen for pulpwood, box lumber, and many other wood products. The annual cut of aspen lumber in the region increased from approximately 67 million board feet in 1941 to 152 million board feet in 1946. In spite of this increased use, aspen still remains the only major tree species in the Lake States in which annual growth exceeds annual drain. It represents the major forest resource in this region that is presently available for sizable plant expansion if a reasonable balance is to be maintained between growth and drain.
