First-year effects of logging on forage production.

Abstract

Significant ecological changes that effect range livestock economy are occurring as a result of logging in the 13,000,000 acres of ponderosa pine forest range lands of the Pacific Northwest. These forests provide 90 percent of the summer range area and 70 percent of the summer range grazing capacity in Eastern Oregon and Washington; about 270,000 acres undergo partial cutting each year. In many stands a second cutting is expected in about four decades. Because these cuttings alter the understory plant cover, they are of major concern to livestock owners, big game interests, and range administrators. These groups need to know the effects of logging on forage production so that they can make any necessary adjustments in range management plans.
