DescriptionThe tremendous destructive capacity of forest insects in reducing our resources of usable timber is becoming increasingly apparent as the shoe of the forest economy pinches tighter. The U.S. Forest Service's recent TIMBER RESOURCE REVIEW, which presents the findings of the most comprehensive survey to date of the present and future timber supply of the United States and coastal Alaska, gives a graphic picture of their importance. For example, forest insects killed more trees in 1952 than any other agent. The growth impact (tree mortality plus growth loss) by insects alone amounted to 16 percent of the total on growing stock and 20 percent of that on sawtimber. In the Northeast, outright tree mortality is relatively less important than in other regions, but the loss in growth and merchantable volume is considerable.
