Elephant Hill, one of the largest remaining open spaces in Northeast LA, is a vital habitat that has become the focus of a community-driven conservation effort. In 2023, the Natural History Museum of LA County co-hosted the first Elephant Hill Community Nature Celebration and Habitat Survey with local groups like Save Elephant Hill and the North East LA Black Walnut Day Coalition. This event highlighted the area's ecological significance, with participants documenting species like the Southern California black walnut, a threatened tree native to the region.

The fight to protect Elephant Hill is ongoing and complex, involving legal battles, grant applications, and navigating the challenges of land ownership. The hill's 110 acres are partly public land, while the rest is subdivided into small lots with more than 300 individual owners. Despite these challenges, local groups are dedicated to preserving the space, using community science to document and protect its unique biodiversity. Their efforts emphasize the importance of public access to green spaces and the role of residents in land use decisions.

The Southern California black walnut tree, a resilient yet threatened species, has become a symbol of the community’s efforts to protect Elephant Hill. Organizations like Coyotl + Macehualli have utilized platforms like iNaturalist to track and raise awareness of the tree's presence, countering development pressures that threaten the habitat. These efforts underscore the importance of community-led conservation in defending not just the land but also the cultural and ecological heritage of the area.

As climate change and urban development continue to pose threats, the community's role in protecting Elephant Hill grows increasingly crucial. Through events, education, and outreach, residents are forging strong partnerships with institutions like NHM to ensure that Elephant Hill remains a sanctuary for wildlife and a source of inspiration for future conservation efforts. The collaboration between these groups highlights the power of relationships and the need for a comprehensive, community-driven approach to conservation.
