Aspen Bibliography
Aspen occupies 20 million acres of Lake States timber land, or 39 percent of the total forest area. In 1945 there were 6 1/3 billion feet of aspen saw timber 9 inches d.b.h. and larger, and a larger cubic volume of smaller material. The cut of aspen lumber was 152 million board feet in 1946, and the forest could sustain a much larger annual cut.
