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.
