Pepperwood's mission is to inspire conservation
through science.

Pepperwood's 3,200 acre preserve serves as a refuge for over 900 species of plants and animals. We are leaders in ecosystem-climate research, producing critical science to help guide our region's natural resource management and conservation planning. Pepperwood also offers environmental education opportunities for all ages to cultivate an ethic of conservation in our North Bay region.

Strategic Plan 2020-2025

With four main initiatives, we're cultivating a path to resilience for our entire community.

Our Preserve sits within the traditional homeland of the Wappo people. We respect and honor past, present, and future generations of Wappo and their continued connection to this land.
