Project: San Francisco Estuary Invasive Spartina Removal and Tidal Marsh Restoration Project, Phase II

Description: This Project will enhance ecosystem function and overall ecosystem health for the benefit of endangered species including California Ridgway's rail and salt marsh harvest mouse as well as many other native tidal marsh dependent fish, migratory birds, and wildlife. The Project will reverse coastal wetland habitat degradation and enhance 70,000 acres of estuarine intertidal wetlands and adjacent mudflat habitat by mapping and treating invasive Spartina bay-wide, planting 30,000 native tidal marsh plants and constructing 10 high tide refuge islands to increase resiliency in several critical tidal marshes.

Reference Number: 3600BQ1996001

Implemented By: California State Coastal Conservancy

Objective: Specific objectives are: 1. Two years of annual inventory and mapping of invasive Spartina on 70,000 acres of tidal wetlands and adjoining mudflats. 2. Complete annual herbicide treatment of invasive Spartina patches throughout the life of this Agreement. 3. Conduct annual pre- and post-treatment monitoring to assess the effectiveness of treatment and restoration work throughout the life of this Agreement. 4. Monitor treatment sites for invasive Spartina throughout the life of this Agreement. 5. Install and monitor 30,000 native tidal marsh plants and 10 high tide refuge islands for the California Ridgway’s Rails. 6. Reintroduce native Spartina where invasive Spartina has been extirpated. 7. Conduct 2020 monitoring of California Ridgway’s Rail to estimate rail population at each site throughout the life of this Agreement. 8. Work with restoration & non-profit partners and agencies to share best management practices (BMPs) to prevent additional invasive Spartina spread.
