Research and Studies
A plethora of ongoing scientific research abounds at Yosemite National Park, from declining animal species studies to invasive plant removal strategies to human carrying capacity issues.
Yosemite has expanded its resources management and science staff to more than 100 people. The park serves as a public meeting place for scientific symposiums--topics include fire science, hydroclimatology, archeology, and bird surveys--with scientific papers presented at the monthly Yosemite Forum and in-depth research in the Yosemite Science publication, launched winter 2011. The park also processes hundreds of research permits every year for its staff and outside interests. The park is proud to sponsor the first park-based social science branch, which serves as a model for ground-breaking work in visitor use and user capacity issues.
Learn more about Yosemite's research through the following:
Ongoing Scientific Research: Research projects include the User Capacity Management Monitoring Program, the Half Dome Cables Trail Study, and the High-Elevation Aquatic Resources Management Plan. Find topics sprinkled throughout the Yosemite web site.
GIS in the Park: Geography is both a natural and a cultural science. View national GIS data sets, including from Yosemite National Park, on an NPS Data and Information online clearinghouse. See nationwide GIS Data, and view Yosemite's GIS data sets, covering topics from geology to fire to soils, or California-specific GIS data.
Planning: Yosemite's staff researches and presents many of its projects for public review. Read through suggested documents as a great way to start getting involved in park projects, such as the Merced River Plan and the Tuolumne River Plan. Understand what is going on and the next steps for your involvement.
Visitor Use: Social scientists study how humans interact with the landscape. View comprehensive reports on summer and winter visitor use. Or, get quick answers to some of the most common questions regarding park statistics. How many visitors come to Yosemite each year? How many miles of trails exist in the park?

Did You Know?
At the east end of El Portal, just west of Yosemite National Park’s boundary, changing river gradients, glacial history, and powerful floods have created a boulder bar with boulders much larger than typically found in such deposits. This is no ordinary boulder bar, however, for it contains massive boulders over a meter in diameter and weighing many tons.
