Restoration of the Mariposa Grove of Giant Sequoias EIS
The Mariposa Grove of Giant Sequoias contains about 500 mature giant sequoia trees that are among the oldest, rarest, and largest living organisms in the world. In 1864, Congress passed landmark legislation preserving the Mariposa Grove of Giant Sequoias and Yosemite Valley. Nearly 150 years later, comprehensive action is needed to ensure that the Grove continues to thrive and provide inspiration and enjoyment for future generations.
The Mariposa Grove Final Environmental Impact Statement (Final EIS) presents a plan to restore ecological processes and increase the resiliency of the Mariposa Grove while improving the overall experience for visitors. The Final EIS describes and analyzes three action alternatives and a no action alternative to achieve these goals. More detail on the alternatives is available in the Final EIS by clicking on the "Document List" link on the left-hand side of this screen.
Input from the public, tribal partners, and agencies has helped to shape this plan since the beginning of public scoping and consultation in 2011. The park received 334 comments during the 60-day public review of the Draft Environmental Impact Statement released in February of 2013. Key revisions to the preferred alternative between the draft and final EIS include refinements at the South Entrance to ensure adequate parking, provision of additional parking near the picnic area for periods when the shuttle is not in operation, and exploration of new options for the location(s) of leach fields.
A minimum 30-day no-action period will follow the U.S. Environmental Protection Agency notice of availability of the Mariposa Grove FEIS in the Federal Register. The NPS will prepare a Record of Decision (ROD) no sooner than 30 days after release of the FEIS. After approval of the ROD by the Regional Director, the NPS will announce the selected plan through local and regional press and on this website.
