Tree San Diego's Rob Krier highlights the work of Jim Crouch, a retired science teacher with a passion for restoring Southern California’s native oak population. Crouch’s efforts have focused on reintroducing Engelmann oaks (Quercus engelmannii), a species once abundant in the region but now facing habitat loss and decline. Since 2018, he has grown over 3,000 coast live oaks and is working toward an ambitious goal of planting 20,000 Engelmann oaks by 2026.
Crouch’s process starts with collecting acorns from healthy, mature trees and carefully nurturing them in nurseries before transplanting them to restoration sites. He emphasizes the importance of oaks as a keystone species, supporting diverse wildlife and playing a vital role in local ecosystems. “More species depend on oaks than any other tree,” Crouch notes, explaining how native plants and animals have evolved alongside these trees for generations.
His mission has brought together volunteers, environmental groups, and Native American tribes in a collaborative effort to restore native landscapes and increase biodiversity. By working with local communities, Crouch is not just planting trees—he’s planting the foundation for healthier, more resilient ecosystems.
As Crouch says, “Oaks are about more than just trees; they’re about restoring balance, providing habitat, and ensuring the land thrives for future generations.”
Tree San Diego is inspired by this dedication to restoration and sustainability. Together, we can all make a lasting impact on our natural environment.
