Crab Team is a project of Washington Sea Grant at the University of Washington that aims to learn about Washington’s inland shorelines and monitor them for invasion by the European green crab. We partner with volunteers, tribes, and agencies to survey habitats that could be affected by the globally-invasive crab, with the goal of detecting it at the earliest possible stage of establishment, increasing our chances of controlling populations and reducing impacts.
Washington’s diverse and productive salt marshes and pocket estuaries, already threatened by shoreline development and pollution, now face a new invader. The European green crab (Carcinus maenas), considered one of the world’s worst invasive species, recently entered inland waters of Washington. If a population establishes, it could threaten native species in these habitats.
