The National Park Service long has been empowered by Congress to manage the resources that lie within the National Park System, whether the focus is cultural, historical, or natural resources such as wildlife. Even wildfire is a management concern for the agency. But what role should politics play in that decision-making approach, which is supposed to be based on "best available science"? That's an increasingly important question as more and more attempts are mounted to tell the Park Service how things should be managed.
