The Baylands Habitat Map 2020 provides a critical foundation for calculating tidal wetland extent and wetland restoration progress. The latest habitat monitoring from the Wetlands Regional Monitoring Program (WRMP) reveals that San Francisco Bay’s tidal wetlands cover 53,700 acres as of 2020, marking an increase from previous estimates. This growth highlights the success of regional restoration efforts despite nationwide tidal wetland declines. The recently released report, Tracking Tidal Wetland Extent in San Francisco Bay: A 2020 mapping update, details these mapping efforts and results. The WRMP has also developed the new versioned and citable Project Tracker Tidal Wetland Restoration Map (PTTWRM), a product made from Project Tracker.

To learn more about how far our region has progressed towards having 100,000 acres of tidal wetland, and how the Baylands Habitat Map 2020 and PTTWRM can be used as tools for tracking progress, please watch this informative webinar on these topics from April 16, 2025 (video embedded below).

This webinar is intended for those who track and/or communicate about regional progress in wetland restoration, those who want to use the Baylands Habitat Map and Project Tracker for their own habitat tracking in the Bay, and anyone else interested in the new products and findings.
