A marine zoologist by training, Silberstein has focused his career on the conservation and study of coastal wetlands, including Elkhorn Slough, one of California’s most significant wetland ecosystems. He will remain in his executive role until a successor is appointed.
The Foundation’s Board of Directors has established a Transition Committee and engaged Potrero Group, a nonprofit executive search firm, to conduct a national search for the next director.
During Silberstein’s tenure, the Foundation developed into a nationally accredited land trust and significantly expanded conservation efforts. The organization has conserved more than 4,200 acres of watershed lands and restored over 2,000 acres of coastal and estuarine habitats, including areas critical to several endangered species.
Through a partnership with the Elkhorn Slough Reserve, managed by the California Department of Wildlife with support from NOAA, the Foundation has helped protect over 6,500 acres of coastal habitats, farms, and ranches. The Reserve hosts thousands of students and tens of thousands of visitors annually, providing research and education programs on the coastal environment.
“Mark’s dedication and collaborative spirit have been truly transformative for the Elkhorn Slough Foundation,” said Susan Matcham-Hernandez, Board President. “His legacy is a strong and resilient organization with a deeply committed team and a string of conservation successes. Thanks to his leadership, this is a moment of strength for the Foundation, making it an excellent time for a leadership transition.”
The Elkhorn Forever campaign, completed under Silberstein’s leadership, raised over $13 million for new land acquisitions and ongoing stewardship. Silberstein said, “It has been my incredible honor and a privilege to work with so many dedicated people to conserve and restore Elkhorn Slough. I am confident the Foundation is ready for its next stage of growth, and I am excited to support the search for a new leader who will continue our vital work.” n
