A proposed rollback of the Roadless Rule, expected in 2026, could threaten critical wildlife habitats and watersheds that supply drinking water to millions of Americans.

The Trump administration is proposing a rollback of the Roadless Rule, a move expected to be formalized in 2026. This policy change would open protected wild areas to development, potentially fragmenting habitats and impacting watersheds that provide drinking water to 47 million Americans.

Impact on Wildlife Habitats

Roadless areas serve as critical core habitats for various species, including those facing risks to their long-term survival. Research indicates that every formal roadless area supports at least two species of conservation concern, with a median of 10 such species per area. In Arizona, some roadless areas provide habitat for up to 62 of these species. Specific examples include the relictual slender salamander in California, where over half of its suitable habitat is located in roadless areas. Additionally, nearly 40 percent of the Mount Pinos lodgepole chipmunk population resides in these protected zones.

Watershed Health and Public Opinion

The Forest Service uses road density as a primary indicator in its Watershed Condition Framework to assess water quality and quantity. If roadless protections are removed, the resulting road construction could block stream flow and increase sediment levels, potentially leading to higher water purification costs. A review by the Center for Western Priorities found that public comments submitted on the rescission notice overwhelmingly opposed the rollback. This follows strong public support for the original Roadless Rule when it was established in 2001.
