Ackerson Meadow is part of the largest mid-elevation meadow complex in Yosemite National Park, California. It is one of the largest mid-elevation montane meadows in public ownership in the Sierra Nevada and a critical biodiversity hotspot and wildlife corridor. Due to over a century of landscape manipulation, including domestic water diversion, farming, ranching, and timber harvest, wetlands within Ackerson Meadow have been lost and are continuing to be threatened.

In partnership with American Rivers, The restoration will re-establish the natural connection between the stream channel and the floodplain by slowing down the flow of water and spreading it out onto the floodplain surface and encouraging sediment deposition. The project is the largest ‘full fill’ meadow restoration attempted in the Sierra Nevada to date, with the promise of restoring biodiversity and enhance the ecosystem of the Sierra Nevada.
