Mariposa Grove Restoration Project

The Mariposa Grove Restoration Project has been the largest restoration effort in Yosemite’s history, using a variety of restoration measures to enhance both ecosystem processes and visitor experience in the Mariposa Grove. Over a century of visitor use has resulted in infrastructure, trails, parking lots, and roads that has fragmented habitat and jeopardized essential ecosystem processes. In 2011 the National Park Service (NPS), with financial support from the Yosemite Conservancy, began the planning process to initiate restoration actions in the grove. At the end of 2013, the Final Environmental Impact Statement was released, with restoration activities beginning in July 2015.
