Restoring Yosemite’s Giants

Mariposa Grove of Giant Sequoias

Yosemite National Park, CA

Enhancing Resiliency

With more than 500 giant sequoias, Mariposa Grove is the largest of three relict groves within Yosemite National Park. The past 150 years of human intervention have altered important hydrological and forest regimes necessary for regeneration of the giant trees. In response, this project restores dynamic ecological processes and increases the treasured grove’s ability to withstand current and novel stressors. 

Access for All

The project improves visitor access while protecting natural and cultural resources. A former vehicular road and parking lot is replaced by a pedestrian-oriented experience that immerses visitors in the restored wetland and majestic forest environment.

Restoring Ecological Processes

The multifaceted restoration delivers a profound positive impact, catalyzing regeneration and enhancing ecosystem resiliency for a sustainable future. Key elements include reconnecting natural hydrologic flows, increasing prime giant sequoia habitat, conducting ongoing prescribed burning, and structuring meaningful visitor education and recreation experiences that protect sensitive resources.
