In commemorating the fiftieth anniversary of the Wilderness Act, we examine what might be the next chapter in wilderness politics, designation, and management. Congressional polarization may push wilderness politics onto different political pathways, including action by the executive branch aimed at protecting wilderness-eligible lands. Outside of Congress, collaboration will also continue to shape wilderness politics in the future, with questions focused on the scope and degree of compromise in wilderness legislation. There will also be increasing demands to control and manipulate wilderness in the future. Yet despite these challenges, the reasons for adding to the Wilderness Preservation System are stronger in 2014 than they were fifty years ago.
