At the start of the 20th century, the Warren area was known as the Allegheny brushpile. The logging industry stripped the hills of all timber and just walked away. The U.S. Forest Service bought the land and started a long-term revitalization. Through their stewardship, the Allegheny National Forest (ANF) is what it is today. We have world-class black cherry, impressive oak stands, and a good mixture of hardwoods. The streams are clear, and fish and wildlife abound. Most of this protection came through the EPA's (Environmental Protection Agency) mandatory NEPA (National Environmental Policy Act) ruling. Areas to be developed must be studied to determine the impact on plants, animals, and watercourses. In the past, this has worked very well in preserving the wilderness feeling of this fantastic forest.
