The Elkhorn Slough

A MAGICAL PLACE OF BEAUTY AND WILDLIFE

THE ELKHORN SLOUGH 

Other than San Francisco Bay, the Elkhorn Slough harbors the largest tidal salt marsh in California, meandering seven miles inland from the center of Monterey Bay, which is famous for whale watching. The Elkhorn Slough is a biologically rich estuary providing habitat for an array of resident and migratory birds, plants, marine mammals and fish, and has been identified as a Globally Important Bird Area by the American Birding Conservancy.

With the highest concentration of Southern sea otters in the world, the Elkhorn Slough is home to up to 140 otters that eat, sleep, and play in its waters.  The Elkhorn Slough is a diverse estuary with harbor seals and sea lions visible year-round. Over 340 species of birds can be seen over the course of the year as they journey along the Pacific flyway. The Elkhorn Slough provides a critical service to the environment as it naturally filters and removes impurities from the water before it enters the ocean. The Elkhorn Slough also acts as a carbon sink sequestering carbon from the atmosphere to slow climate change.

The Elkhorn Slough Foundation

CONSERVING AND PROTECTING

ES protected lands 0309 lr

The Elkhorn Slough Foundation’s mission is to conserve and restore Elkhorn Slough and its watershed. Partnered with the Elkhorn Slough National Estuarine Research Reserve, they support outreach, education and research.  Their main role as a land trust is the main focus of their work.  They manage nearly 4000 acres in the Elkhorn watershed, restoring tidal wetlands, coastal prairies, oak woodlands, freshwater ponds and other key habitats. 

Currently, The Elkhorn Slough Foundation is restoring a tidal wetlands area just past MoonGlow Dairy. Spend a day on the Slough and see the great work that The Elkhorn Slough Foundation does.

Oak and Wetland Restoration 

2012 euc

An up-and-coming project at the Reserve is to restore native grassland and coastal live oak groves. The grasslands and the oak groves at the Elkhorn Slough have been displaced by non-native invasive eucalyptus trees. Returning the Elkhorn Slough to a more native landscape will enhance habitat for threatened species such as the Santa Cruz long-toed salamander and Califonia’s red-legged frog. 

This project will be carefully planned out using a science-based approach and once started will take 10 years to complete.

Sand Hill Farm Restoration

In 2016 the 107 acre Sand Hill Farm was acquired by the Elkhorn Slough Foundation. The farm is to be returned to its native habitat except for 15 acres that will be used for an organic farm.

The process included cleaning up farm debris and returning the upper slopes to native oak woodlands for groundwater recharge and soil conservation.

Sand Hill Farm is the seventh former-farmlands property that Elkhorn Slough Foundation is restoring to its more native environment.

Tidal Marsh Restoration Project

subsided marsh parsons

 Project design led by ESA-PWA and included H.T. Harvey, Moffatt and Nichol, Moss Landing Marine Laboratories and ENGEO, this is the first major salt marsh restoration project in the Elkhorn Slough.

After careful thought and planning, the project began adding sediment to a subside marsh of the Elkhorn Slough. The innovative design was to ensure a sustainable marsh. A marsh that will perform better in the face of sea-level rise than the other low-level marshes.
