[Excerpt] Overview: What I Found: Around 29.5 million acres of Inventoried Roadless Area lies within 42 commercial river HUC8 watersheds and is not otherwise protected by Wilderness or National Park designation. In plain language, the roadless areas upstream of these rivers protect more land from development than the entire National Wilderness Preservation System within the Forest Service. More land, but without the permanence of formal designation. Under a conservative development scenario, projected new road miles total 22,266. Under the less restrictive scenario, the total is 66,847 miles.
