In 2016, with support from Conservancy donors, Ackerson Meadow became part of Yosemite, adding 400 acres of protected habitat to the park’s western edge.

Meadows account for less than 3 percent of Yosemite’s total area, but support almost half the park’s native species. Scientists know rare species, such as the great gray owl and willow flycatcher, live in Ackerson Meadow, and they are eager to learn more about the plant and animal communities that rely on Yosemite’s newest habitat. Using field surveys and remote equipment, scientists will document the meadow’s diverse species, including amphibians, songbirds, grasses and wildflowers, and will share their findings with the public through social media and educational materials. This research will enable the collection of baseline information necessary to shape future meadow-focused conservation work, including research, restoration and wildlife management.

Your contribution helps fund state-of-the-art research to understand and protect Yosemite’s newest meadow habitat.

Project Notes
Yosemite Scientists inventory animals in Ackerson Meadow, including the goshawk.

Almost half of the native species in Yosemite can be found in meadow habitats. We know Ackerson Meadow harbors a rich assemblage of flora and fauna, but the full extent of its diversity remains a mystery.
