概要	Visitor Experience and Resource Protection (VERP) is the U.S. National Park Service's framework for addressing carrying capacity by managing the conditions of both park resources and visitor experiences rather than counting visitors. Set out in the 1997 NPS handbook, VERP reflects the same insight that drove the Limits of Acceptable Change system: there is no single defensible number of visitors a park can hold, so management should instead define the conditions it wishes to maintain and act to keep them within acceptable limits. VERP proceeds by grounding the plan in the park's purpose and significance, dividing the park into management zones with prescribed desired conditions, selecting measurable indicators of quality for resources and experiences, setting standards for those indicators in each zone, monitoring conditions, and managing visitor use whenever a standard is violated. It is the park-planning counterpart to LAC and is woven into the general-management-planning process.	Tourism carrying capacity assessment estimates the maximum level of visitor use a destination or site can sustain before its environment, infrastructure, host community, or visitor experience begins to deteriorate unacceptably. The concept, given its influential tourism formulation by A. M. O'Reilly in 1986, recognises that carrying capacity is not a single number but a set of limits operating across distinct dimensions — physical and ecological capacity on the resource side, social capacity on the host and visitor side, and economic capacity on the activity side — with the binding constraint being whichever is reached first. Carrying capacity is the conceptual engine behind Butler's Tourism Area Life Cycle, explaining why unmanaged growth leads to stagnation, and it underpins much of sustainable destination management even as it has been refined into more flexible, indicator-based frameworks.
