RAISING HESTER MARSH Elkhorn Slough has lost at least 50% of its tidal wetlands in the last 150 years due to human activity, primarily historic diking and draining for grazing and cultivation.

Under the guidance of Tidal Wetland Program Director Monique Fountain, the
Elkhorn Slough Reserve is responding by raising the elevation of Hester Marsh on the southern shores of Elkhorn Slough. Looking across the site, it’s hard not to be impressed by the project's vast scope and scale — the most extensive high marsh landscape in the estuary, restored to an elevation that will allow it to naturally track sea level rise.
