A week of meadow restoration, conservation education, and exploration in and around Yosemite National Park gave 21 members of the Sierra Nevada AmeriCorps Partnership (SNAP) an opportunity to sharpen their skills while helping restore one of the Sierra’s important natural landscapes.
The Sierra Nevada Alliance recently shared a firsthand account of the program’s 2026 Spring Training, held near Groveland and Yosemite National Park. The week brought together AmeriCorps members from across the Sierra Nevada who are serving in restoration, environmental education, volunteer management, and community engagement positions.
One of the week’s highlights took place at Ackerson Meadow, a 400-acre meadow just west of Yosemite National Park that has been undergoing a long-term restoration effort since the National Park Service acquired the property in 2016.
For decades, cattle ranching, road construction, and other land uses altered the meadow’s natural hydrology, creating deep channels that drained water away from the landscape. Restoration specialists are now working to reverse those impacts using techniques inspired by one of nature’s own engineers—the beaver.
Working alongside National Park Service staff, American Rivers, and restoration specialists, SNAP members helped build Beaver Dam Analogs (BDAs)—simple structures made from wooden posts, branches, and natural materials that mimic natural beaver dams. The structures slow water movement, encourage groundwater recharge, trap sediment, and reconnect streams with surrounding floodplains, helping restore healthier meadow ecosystems. Members also planted willows and installed fascines, bundles of vegetation designed to further slow water flow and stabilize the landscape.
The experience also offered practical career development.
During lunch discussions, National Park Service employees shared their own career paths into conservation while offering advice on building resumes and navigating federal hiring. Participants also learned about the monitoring of the threatened native turtles that inhabit Ackerson Meadow, giving members an opportunity to see wildlife conservation firsthand.
The second day shifted from restoration work to interpretation and education inside Yosemite National Park.
Guides from Yosemite Conservancy led the group through Yosemite Valley, explaining how tectonic forces, granite formation, glaciers, and ongoing erosion created many of the iconic landscapes visitors see today. Members also learned about cliff ecology, the role of lichens in revealing recent rockfall, and the conservation success story of peregrine falcons, whose recovery has been supported in part through cooperation between wildlife managers and the climbing community.
Beyond the science, the training emphasized an important lesson for future conservation professionals: helping people connect with nature is just as valuable as restoring it.
The interpretive hike demonstrated how skilled guides use everyday observations—from birds and wildflowers to geology and wildlife—to encourage visitors to better understand and appreciate public lands. According to the Sierra Nevada Alliance, these storytelling skills are an important part of inspiring conservation and stewardship.
The Sierra Nevada AmeriCorps Partnership is an 11-month service program that places members with organizations throughout the Sierra Nevada to work on conservation, environmental education, watershed restoration, forest resilience, and community engagement projects.
The Sierra Nevada Alliance’s blog describes the Spring Training as more than just a professional development event. For many participants, it was also an opportunity to reconnect with fellow service members, build friendships, and gain a deeper appreciation for the work being done to protect the Sierra Nevada.
