Aprašymas
Eastern Oregon has an estimated 42.2 million acres of land. About 32 percent of this land is forested with 76 percent of the forested portion being nonreserved timberland. About 71 percent of the timberland exists on National Forest System lands. Within the timberland area outside of national forests, net volume of growing stock is estimated as 3.5 billion cubic feet. About 41 percent of the growing-stock volume is on forest industry land, 48 percent on other private land, and 11 percent on other public land. Approximately 99 percent of the total growing-stock volume is in coniferous species, with ponderosa pine accounting for 43 percent followed by Douglas-fir at 22 percent of the conifer volume. Estimated net annual growth of growing stock for nonfederal lands is 59 million cubic feet, and average annual mortality for this timber is an estimated 45 million cubic feet.
