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.
The Project Tracker tracks restoration projects, including maps, habitat plans, contact information, and a library of project files.
The Landscape Profile Tool summarizes ecological information at various spatial scales for assessment, planning, and reporting.
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.

CRAM is a standardized, scientifically defensible rapid assessment method for monitoring the ecological conditions of wetlands throughout California. Because it is standardized, one can compare ecological conditions of wetlands locally, regionally and statewide.
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.
The CRAM Bar-Built Estuarine module is used for assessing reaches of coastal rivers and streams that are ecologically influenced by seasonal closures of their tidal inlets.
This tool provides a permit negotiation tool for applicants and Regional Water Board staff to work together on preparing a permit for a 401 Water Quality Certification or Waste Discharge Report for projects impacting waters of the US or California. The application tool will streamline 401 Certification applications, provide access to historical 401 cases, and enable standardized reports on the status and trends of 401 projects and ambient conditions for watersheds, regions, and statewide.
With California's drought rapidly changing the outlook for natural resources, decision-makers must be equipped with information and tools that facilitate clear and rapid decisions. The proposed grant would fund the standardization, visualization, and sharing of Level 3 data.
Eelgrass (Zostera marina and Z. pacifica) is recognized as an important ecological resource in nearshore open coast areas, shallow bays, and estuaries throughout coastal California.
Information and maps for 168 projects from the San Diego Regional Water Quality Control Board were uploaded to the Project Tracker database. These projects can be viewed on EcoAtlas and the California Wetlands Portal. This project also provided guidance and training to support the San Diego Regional Water Quality Control Board's participation in the Online 401 Pilot Study.
This project will create an EcoAtlas user community for the Lahontan region of the Sierra Nevada to develop capacities within the region to apply EcoAtlas through existing local, regional, state, and federal programs to track projects and summarize map-based and rapid assessment information at the watershed scale.
