More than 9 million acres of forest in Washington and Oregon should be selectively logged and burned to make the remaining trees more resistant to wildfire, disease and drought, according to a new study by the U.S. Forest Service and The Nature Conservancy. The study looked at forests in Eastern Washington, Eastern Oregon and Southwest Oregon across federal, state, tribal and private ownerships. About 40 percent of those forests are experiencing conditions outside of their historic range, it concluded.
