. Central States timber resources. Forests and forestry. GROWTH AND DRAIN The Central States forests, in general, have sufficient growing stock to permit rapid stand improvement by applying good forest management practices. The average volume of growing stock is about 580 cubic feet per acre and 40 percent of it is in trees 10 inches in diameter or smaller; an additional 24 percent is in trees in the 12- and 14-inch diameter classes. To obtain maximum growth and quality most of the volume should be in the 16- and 18- inch diameter classes. Annual growth of sawtimber in the Central States exceeds 4 billion board-feet. This amounts to about 100 board-feet per acre per year - a figure that could be doubled or tripled with reasonable effort. About 80 percent of the forest land is well enough stocked so that volume will increase rapidly if the stands are adequately protected and well managed. A trend in that direc- tion is indicated by the fact that at the present time the forests are growing more than twice as much as is being 8.
