Yosemite National Institutes operates environmental education programs, based on curriculum standards, at three locations: Marin Headlands, Yosemite National Park, and Olympic National Park. Intel California Corporate Affairs provided YNI with a grant to purchase handheld computers for use at its Yosemite site; students use the computers to gather data on natural resources, such as old growth trees, which is used by the U.S. Forest Service to monitor the changes and health of Yosemite.
