| IRS990/Activity2/Description | 0 | The Tidal Wetland Program- TWP is a multi-agency effort focused on addressing the most critical ecological challenge facing the tidal portions of Elkhorn Slough. Historic modifications of Slough hydrology has led to the dramatic loss of vegetated marsh land. In collaboration with over 100 scientists, resource managers, local residents and other stakeholders, the Tidal Wetland Program led an Ecosystem Based Management approach to arrest this loss of habitat and restore a more natural function to the slough system. The result of this is the implementation of more natural tidal flow to the Parson's slough complex on the Elkhorn Slough National Estuarine Research Reserve which protected over 450 acres of tidal wetlands in the Elkhorn system. Ongoing work is focused on the restoration of wetlands through the beneficial reuse of clean sediments to rebuild subsided marshes and by the repair and management of water control structures. |

| IRS990/Description | 0 | Land Stewardship Program- This program is responsible for the ongoing restoration, maintenance and management of nearly 4,000 acres of land in the Elkhorn Slough watershed. This past year, the Stewardship team again engaged dozens of community volunteers to assist with a wide array of conservation actions, including the removal of tons of trash and debris, control of exotic invasive weeds, monitoring key lands and species, mapping natural resources, collecting, germinating, growing and out-planting thousands of native plants. This program continues to transform hundreds of acres of degraded worn-out sand hills into vital, healthy habitat. |
