Yosemite National Park announces the release of the Restoration of the Mariposa Grove of Giant Sequoias Final Environmental Impact Statement (Mariposa Grove FEIS). This landmark plan provides the foundation for the restoration and site improvements in the park’s largest grove of giant sequoias. The Mariposa Grove, along with Yosemite Valley, was included in the Yosemite Grant that was signed into law on June 30, 1864. This marked the first time the federal government set aside land for protection and is considered to be the genesis of the national park idea. https://www.nps.gov/yose/learn/news/mgrovefeis.htm
