WARREN COUNTY, Pittsburgh — Local leaders and timber industry professionals are hoping for an economic boost as logging increases in the Allegheny National Forest. The timber industry has strong roots in the four counties that contain the Allegheny National Forest: Elk, Forest, McKean, and Warren. With fewer than 150,000 residents, it’s a small enough region where almost everyone knows everyone else in the business. …“If you’re somebody who lives here, almost everybody is touched in some way by the timber industry,” said Julia McCray, at the Allegheny Forest Alliance, a coalition dedicated to the national forest’s health that includes local officials and people from the timber industry. As logging expands on federal lands amid a Trump administration push for more timber, the effects could be felt for years to come — in the forest and beyond. A single logging operation relies on a multi-step chain of work that employs many.
