Foresters play a major role in managing Oregon's 30 million acres of forestland. Through their management of the 19.4 million acres of Oregon's forest capable of growing commercial crops of timber, foresters help contribute to a significant proportion of Oregon's rural economic base. Fifty-one percent of Oregon's timberland is owned by the federal government and 49 percent by non-federal owners. Most federal timberland is now managed primarily for non-timber benefits with limited timber harvesting. Seventy-five percent of the state's timber harvest for the foreseeable future is expected to come from non-federal lands owned by wood products firms (29 percent), other private landowners (14 percent), and state and local governments (7 percent).
