Compared to its four adjacent neighbors, Oregon has the smallest percentage of its lands designated as units of the National Wilderness Preservation System. While the average of the areas of the five states protected as wilderness is more than 9 percent, in Oregon less than 4 percent of the land is so protected. Oregon has 47 wilderness areas totaling 2,457,473 acres. Additional potential wilderness areas (a.k.a. roadless areas) in Oregon total more than 12 million acres, with approximately 61 percent of that area being generally tree-free (in the Oregon High Desert and other desert areas considered part of the sagebrush steppe, aka Sagebrush Sea) and the remainder generally forested. Congress should expeditiously expand the National Wilderness System in Oregon.
