History and Ecology of Mariposa Grove / Giant Sequoias: Located in the southern portion of Yosemite, the Mariposa Grove of Giant Sequoias is the largest sequoia grove in Yosemite and is home to over 500 mature giant sequoias. The national park idea is rooted in the Mariposa Grove. In 1864 President Lincoln signed legislation protecting the Mariposa Grove and Yosemite Valley for "public use, resort, and recreation." For the first time in our nation's history, the federal government set aside scenic natural areas to be protected for the benefit of future generations. Later added to Yosemite National Park in 1906, the Mariposa Grove is a popular destination within the park.
