Golden Gate National Recreation Area, Including Alcatraz Island Muir Woods National Monument Volume III: vii CONTENTS Volume III: viii User Capacity 9 INTRODUCTION General management plans for national park units are required by law to identify and address implementation commitments for user capacity, also known as carrying capacity. The National Park Service defines user capacity as the types and levels of visitor use that can be accommodated within a particular national park area while sustaining the quality of park resources and visitor experiences consistent with the purpose of that national park. Managing user capacity in national parks is inherently complex and depends not only on the number of visitors, but also on where the visitors go, what they do, and the “footprints” they leave behind. In managing for user capacity, the park staff and partners rely on a variety of management tools and strategies, rather than relying solely on regulating the number of people in a park area. In addition, the ever-changing nature of visitor use in parks requires a deliberate and adaptive approach to user capacity management. The foundations for making user capacity decisions in this general management plan are the purpose, significance, special mandates, and management zones associated with the national park and monument.
