A wetland restoration project is now underway in the 400-acre former herding area known as Ackerson Meadow, which was controversially added to Yosemite National Park in 2016, the National Park Service announced this week. Ackerson Meadow is on the west edge of Yosemite, on Evergreen Road in Tuolumne County, between Highway 120 and the entrance to Hetch Hetchy, and it borders Stanislaus National Forest land. Ackerson Creek flows into the South Fork Tuolumne River. Natural subalpine meadows there used to be magnets for cattle and sheep herders who sought grazelands when they were outside park boundaries.
