Bay Area Aquatic Resource Inventory (BAARI)

The Bay Area Aquatic Resources Inventory (BAARI) is a GIS base map of the Bay Area's wetlands, open water, streams, ditches, tidal marshes and flats, and riparian areas. BAARI was developed using standardized mapping protocols to ensure that the level of detail and wetland classification system is standardized across the region. 

BAARI Mapping Documentation

The Bay Area Aquatic Resource Inventory (BAARI) is a basemap of all tidal and non-tidal aquatic features in the region, and is the Level 1 landscape-scale assessment of the WRMP 1-2-3 framework. This methods document details the mapping methods and standards used to create the basemap and documents QAQC procedures.

California Aquatic Resource Inventory (CARI)

The California Aquatic Resources Inventory (CARI) is a Geographic Information System (GIS) based map of wetlands, streams, and riparian areas within California that is hosted online through EcoAtlas.

Southern California T-sheet Atlas

Robin Grossinger and the Historical Ecology team have completed the T-sheet Atlas. Titled, Historical Wetlands of the Southern California Coast, this study is the first regional assessment of the relative distribution and abundance of different wetland habitat types along the historical Southern California coastline. The T-sheet Atlas describes interpretation and the findings of an initial regional analysis of 26 T-sheets (historical maps of the United States Coast Survey) for the South Coast.

South Bay Salt Pond Restoration Project: GIS & Web Services

The South Bay Salt Pond Restoration Project is the largest tidal wetland restoration project on the West Coast. When complete, the project will restore 15,100 acres of industrial salt ponds to a rich mosaic of tidal wetlands and other habitats.
