In September 2016, Yosemite added 400 acres to its federally protected landscape when Ackerson Meadow, a previously privately-owned area near Hetch Hetchy, officially became part of the national park. The land was purchased and donated to Yosemite through a cooperative effort by The Trust for Public Land, Yosemite Conservancy and the National Park Service.

The 400-acre meadow provides high-quality habitat for a range of wildlife and is home to the Sierra Nevada’s largest known population of great gray owls, a state-listed endangered species. Ackerson Creek, which winds through the meadow, also serves as an important corridor for many animals.

Placing the land under park protection significantly expanded the area of healthy meadow habitat within Yosemite’s boundaries. As part of Yosemite, Ackerson Meadow benefits from the attention of world-class experts in conservation, restoration and wildlife management. With the landmark purchase complete, park experts can now focus on research and restoration projects designed to ensure the long-term health of the meadow and its wild inhabitants.

Yosemite Conservancy donors generously supported the purchase and donation of Ackerson Meadow, which was completed by the Trust for Public Land, in collaboration with the National Park Service and with additional contributions from National Park Trust and American Rivers.

Project Notes

The Ackerson Meadow land has long-been a high-priority target for acquisition by the conservation community because of its healthy meadow ecosystem. This comparatively rare habitat supports a wealth of species.
