"Trees for Trunks": Native Oaks Shade the San Diego Zoo Safari Park's new Elephant Valley

When Elephant Valley opens at the San Diego Zoo Safari Park on March 5, visitors will experience a sweeping new habitat designed around the needs of one of the world's most iconic animals. But one of the most meaningful sustainability decisions behind the project isn't about what was added — it's about what was kept

Rather than clearing the land entirely, the Zoo made a deliberate choice to preserve an existing grove of native oak trees within the footprint of Elephant Valley. Those trees now stand as part of the habitat itself, providing shade, structure, and a living connection to the local landscape.

Oak trees are foundational to Southern California ecosystems. They support hundreds of species, store carbon, stabilize soil, and offer cooling benefits that are increasingly important in a changing climate. Preserving mature oaks isn’t the easy or inexpensive option. It requires careful planning, design flexibility, and long-term commitment, but it reflects a deeper investment in sustaining the environment that already exists.

In a recent behind-the-scenes look at Elephant Valley, Raj Brown, director of horticulture at the San Diego Zoo Safari Park, described the decision as part of a broader philosophy: designing habitats that work with the land, not against it. Rather than starting from scratch, the team allowed the natural landscape to shape the project — a choice that benefits wildlife, visitors, and the region alike. One of the curators also noted how locals are also impacted. “... It’s about being connected to the community and the environment that we live in here. And those oak trees really represent that . . . I love that they saved those oaks.”

The Zoo has also worked on oak species conservation more broadly — not just preserving trees within an exhibit, but participating in regional partnerships to protect and coordinate work on threatened California oak species. This underscores that the oak preservation at Elephant Valley reflects real, ongoing conservation initiatives tied to plant species the organization studies and helps protect.

This kind of thinking is easy to miss when walking through a finished exhibit. The trees feel like they’ve always been there — because they have. And that’s the point. Sustainability often shows up not as something new and flashy, but as a quiet decision to protect what’s already thriving.

As Elephant Valley opens this March, the preserved oak grove stands as a reminder that some of the most lasting sustainability efforts are rooted in restraint, care, and respect for place.
