New York's wilderness-area management guidelines are similar to, if a bit looser than, those followed by the federal government. Any development of new facilities within the unit requires a change to the Unit Management Plan (UMP), or is added only at the UMP's periodic updates, both of which require public comment and extensive review. The UMP is itself governed not only by the state's Environmental Conservation Law but Article 14 of the state constitution, which requires that the Forest Preserve be kept "forever wild" and free for public use beyond any reasonable fee required for a particular activity.
