Erica Harris
Co-Executive Director
As a member of SLT’s co-leadership team, Erica leads stewardship, outreach, and policy & advocacy. This role is critical in expanding stewardship activities to keep pace with SLT’s fast-growing portfolio of conserved lands, connecting people with SLT’s work, and achieving long-term impact.
Erica brings almost two decades of experience in collaborative systems change—leveraging strategic partnerships to solve complex challenges. Erica has a degree in Environmental Studies from UC Santa Cruz and is passionate about work at the nexus of wildfire resiliency and habitat protection, and strengthening organizational best practices for species protection.
Erica was first introduced to Siskiyou County’s stunning biodiversity while working with the US Forest Service in the mid-2000s. This exposure, coupled with a long-time commitment to community science projects, led Erica to launch the annual Mount Shasta butterfly count in 2024. You might find Erica in remote corners of Siskiyou County and beyond—birding, botanizing, and appreciating reptiles and amphibians.

Kristin Davis
Co-Executive Director

She helps hold and refine the organization’s internal systems—from grants and finances to people and processes—while supporting communications and keeping day-to-day work aligned with SLT’s mission and vision. Her work helps create conditions for conservation to endure: steady, supported, and rooted in care.

Early work in a shared leadership role during the completion of her degree in Nature & Culture at UC Davis continues to shape how she approaches her work, with an eye toward connection, collaboration, and the systems that hold it all together.

Outside of work, you can find Kristin spending time exploring the forest adjacent to her home with family, photographing wildflowers, and tap dancing—oftentimes outdoors!
