Visitor Use Research

Below are links to reports and field monitoring guides
published by Yosemite's Visitor Use and Impacts Monitoring Program. Summaries from the most recent year's report can be found on the program's Visitor Use and Impact Monitoring home page. When summary reports are posted for the next year, the current summaries will be compiled into a singe document and will be moved to this page for continued access.

Field Monitoring Guide: This guide is updated dynamically instead of on an annualy basis, with the latest version available online. [4.6 MB PDF]
