According to the folks at Wilderness Watch, the U.S. Forest Service has proposed to build 7.5 miles of permanent firebreaks within the Ventana Wilderness on the Los Padres National Forest in California, using chainsaws, heavy equipment and vehicles. Wilderness Watch is opposing this proposal as a violation of the Wilderness Act, among other things. The issue is complicated by a series of special provisions that Congress added to laws that expanded the Ventana Wilderness over time. These special provisions authorized the use of some “presuppression” work within the Ventana additions, but none authorized chainsaws, heavy vehicles, or permanent 150-foot-wide firebreaks within an area that is supposed to remain “untrammeled by man.”
