California's EcoAtlas provides access to information for effective wetland management. The maps and tools can be used to create a complete picture of aquatic resources in the landscape by integrating stream and wetland maps, restoration information, and monitoring results with land use, transportation, and other information important to the state’s wetlands.

EcoAtlas displays three categories of information as called for in California Wetland Monitoring Workgroup’s Tenets of a State Wetland and Riparian Monitoring Program (WRAMP). These three information categories are consistent with the USEPA’s Level 1‐2‐3 framework for monitoring and assessment of wetland resources.

Maps and spatial information

Interactive, detailed maps of aquatic resources extent (streams, wetlands, riparian areas, and special habitats such as eelgrass) are available as data layers. Existing aquatic resources based on California Aquatic Resource Inventory (CARI) are displayed as the default data layer on the interactive map. EcoAtlas is tracking tool for restoration project activity and provides detailed information and boundaries for restoration projects around the State. Wetland projects are also available as a web service.

General wetland condition information

California Rapid Assessment Method (CRAM) ambient and project survey results, as well as reference network sites, are served through an interactive map. CRAM assessment details, including index, metric and attribute scores, visit dates, assessment area boundaries, and related documents are viewable and can be downloaded.

Specific condition information

EcoAtlas displays detailed condition data on water and sediment toxicity from various studies throughout the State. These data are provided by California Environmental Data Exchange Network (CEDEN) so users may view water quality data relevant to wetland condition.

Information about the data sources used on EcoAtlas is available on the Data page.


With constant renewal and redevelopment, EcoAtlas has been serving the San Francisco Bay Region and broader California constituencies for almost 20 years.


Project Tracker

The Project Tracker tracks restoration projects, including maps, habitat plans, contact information, and a library of project files.

Landscape Profile Tool 

The Landscape Profile Tool summarizes ecological information at various spatial scales for assessment, planning, and reporting. 

CARI Editor

The CARI Editor allows users to submit updates, deletions or new features for streams and wetlands. An email is sent to acknowledge receipt of the request, however the review and processing of edits is dependent on available resources.
