Project overview: Collaborate with the park’s affiliated Tribes to plant, prune, and tend black oak trees in Yosemite Valley, simultaneously restoring habitat and traditional stewardship practices.
How your support helps: For generations, Indigenous people planted and tended California black oaks in Yosemite Valley. Active stewardship, which included planting acorns and careful burning, helped reduce pests, promote seedling growth, and keep the trees healthy. Black oaks hold significant ecological and cultural value, and their acorns provide nutritious food for people and wildlife.
When Yosemite’s first stewards were forced out of their homeland, however, their traditional practices went with them — and in the exclusion of their care, the health of black oaks in the park has declined.
Now, the seven Tribes affiliated with Yosemite are working with the National Park Service to bring their knowledge and techniques back to the oak woodlands. This work is steeped in a sense of urgency: Past Conservancy-funded work found that most of the Valley’s remaining black oaks are older trees, and few saplings are taking root. For traditional oak-tending techniques to continue, they must be practiced and regenerated.
With your support, park crews will work with members from all affiliated Tribes to gather and plant acorns, prune tree limbs, and reduce potential fire fuel, using traditional techniques whenever possible. Meanwhile, park educators will teach the public about Tribal stewardship and the cultural value of black oaks. In addition to saving a biologically and culturally significant tree species, this project honors and restores the role of Yosemite-area tribes as leading stewards of the Valley’s oak groves, and ensures park staff and the public can learn about and from traditional ecological practices.
