Meadows account for less than 3 percent of Yosemite’s total area, but support almost half the park’s native species. Through this 2017 grant, scientists used field surveys and remote equipment to document biodiversity in Yosemite’s newest meadow habitat: Ackerson Meadow. With help from interns, the research team counted songbirds and owls; confirmed the presence of western pond turtles and chorus frogs; identified 37 acres of rare plants; captured more than 10,000 remote camera images of bears, bobcats, mountain lions and other animals; and recorded echolocation calls from 11 bat species.

Your contribution helped scientists collect baseline information necessary to shape future meadow-focused conservation work, including research, restoration and wildlife management.

Completed in partnership with Yosemite National Park.

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.
