CRAM Training sessions for 2020 have been posted on the CRAM website.

Within EcoAtlas, new updates to the CRAM Landscape Profile tool feature estimates of overall ecological condition of streams, estuarine, and depressional wetlands based on probability based ambient surveys that have been completed locally, regionally, or statewide.  Estimates of the proportion of wetland resources that are in good, fair, or poor ecological condition are summarized using Cumulative Distribution Function plots (CDFs).  

Using the Landscape Profile tool, CRAM scores from mitigation or restoration projects can be plotted on a regional CDF to evaluate if the condition of the project falls within the lower or upper 50th percentile score of wetlands in the region and if it is in good, fair, or poor ecological condition based on the standard health classes of CRAM. 

Other CRAM enhancements include include adding a required field for storing the SWAMP Site ID for CRAM assessments within the online eCRAM data entry forms. This will make it easier to access SWAMP water quality data and CRAM assessments from the same location for analysis and reporting.

For more information on using CRAM for project assessment as an element of regulatory, grant, and other management programs, refer to the updated CRAM Technical Bulletin recently published by the California Regional Water Quality Control Board’s Wetland Monitoring Workgroup (CWMW).
