The Charley River is a complete watershed protected within the preserve and is virtually unaltered by modern human activities.
The preserve protects the Charley River in a free-flowing, natural state and the entire 1.1-million-acre Charley River watershed is seemingly unaffected by human activity.
The Charley River basin is a focal point for scientific study of subarctic ecosystems that range from river bottoms to alpine habitat.
The preserve provides habitat for populations of fish and wildlife, including but not limited to peregrine falcons and other raptorial birds, caribou, moose, Dall's sheep, grizzly bears, and wolves.
