California Rapid Assessment Method (CRAM)

Source:

San Francisco Estuary Institute

Description:

CRAM is a cost-effective and scientifically defensible rapid assessment method for monitoring the conditions of wetlands throughout California. It is designed for assessing ambient conditions within watersheds, regions, and throughout the State. It can also be used to assess the performance of compensatory mitigation projects and restoration projects. For more information, visit: https://www.cramwetlands.org/. CRAM analysis and interpretation tools, such as Cumulative Distribution Functions (CDFs) and Habitat Development Curves (HDCs), are available on EcoAtas (ecoatlas.org). For more information on CDFs and HDCs, visit: https://www.sfei.org/projects/california-rapid-assessment-method-wetlands-cram-hdcs-and-cdfs.
