Social scientists measure experiential factors (perceptions of quality of services, crowding, importance of activities offered, for example) inherent in visiting the park.

Understanding the natural and cultural contexts of parks has long been an important aspect of managing the National Park System. The agency's governing legislation protects these resources and thus continues to play a critical part in the designation and management of park units. Providing a high-quality visitor experience has always been a core component in that same legislation. Recently, however, managers have noticed increasing numbers of park visitors are now affecting the quality of both natural and cultural resources. Land managers are using social science methods to associate visitor characteristics and behavior with resource conditions. This approach is helping park managers take a more in-depth look at how science can manage visitor use before unacceptable impacts to resources occur. Given the complexity of visitation in a park like Yosemite, social science is one way to understand resource protection from visitor caused impacts.

The Visitor Use & Social Sciences branch within the Resources Management and Science division conducts research to inform visitor use management, impact monitoring, and planning-related projects. A focus is put on the social-psychological components of resources management, including the visitor experience. Additionally, existing conditions and physical resource impact and visitor-use documentation are all components of understanding the relationships between visitor use and the quality of biophysical, cultural and social/experiential resource conditions within the park. This includes transportation, front country, and Wilderness visitor-use issues. The national parks, like other federally protected lands, offer a variety of visitor experiences and social resources that can and should be maintained.

According to the 1916 National Park Service Organic Act, quality visitor experiences should be fostered while providing for natural and cultural resource conservation. Solitude is a great example of a social resource that numerous visitors seek when they venture into Yosemite’s designated Wilderness. With excessive visitor use, a valued resource, such as a sense of solitude, can diminish or even disappear.

Here are ways to understand visitor-use patterns in parks:

• Documenting and modeling pedestrians;
• Modeling transportation modes and systems;
• Understanding visitor demographics, trip and visit characteristics;
• Evaluating visitor services and facilities, expenditures, and opinions about selected issues via surveys; quantifying resource impacts under a variety of use levels;
• Understanding visitor perceptions of crowding, wait times and various levels of service.

Learn about the park's Visitor Use & Impact Monitoring Program, which has been developed to report on how Yosemite officials are managing the natural, cultural, and visitor experience. This monitoring program and process is constantly being updated with the advent of technological advances, changes in visitor behavior and the successes that management action yields. An annual report serves as the the progress made over the previous year.

Visitor-Use Research

• Read "Boats, Beaches, and River Banks: Visitor Evaluations of Recreation on the Merced River" [6 MB PDF], released July 2012, as part of Merced River Plan research.
• Examine nationwide NPS visitor use statistics through the National Park Service Public Use Statistics Office and then compare Yosemite's data to other parks' statistics.
• Learn how the University of Idaho's Park Studies Unit operates an NPS social research unit with in-depth visitor studies. Find its Yosemite reports that date back to 1998.
