Description: European Green Crab (EGC) (Carcinus maenas) is one of the most successful invasive predators in coastal and marine systems, having established populations on five continents. On the Pacific coast, EGC arrived in the late 1980s and is currently expanding its range and population growth. Recognizing the expansion of EGC, a working group of EGC experts identified a need to track distribution of EGC across the West Coast. This layer represents standardized observation of EGC from a variety of sources.

Recognizing the expansion of EGC, a working group of EGC experts identified a need to track distribution of EGC across the West Coast. This layer represents the presence or absence (or lack of data) of European Green Crab (EGC) within estuaries along the West Coast as part of PSMFC's efforts to maintain a standardized database of EGC status.
