About WSG Crab Team

Overview Banner

Washington Sea Grant’s Crab Team was launched in 2015, in response to a Washington Department of Fish & Wildlife (WDFW) mandate to monitor for European green crabs along inland Washington shorelines. By using citizen science, we are achieving a much greater scale of monitoring than would otherwise be possible, and expanding what we know about the community of organisms that lives in salt marshes and pocket estuaries. Crab Team has two main goals:

  1. Detect European green crab at the earliest possible stage of invasion to increase the ability to control population and reduce green crab impacts.
  2. Build a long-term dataset on green crab and other mobile organisms living in soft sediment habitats to improve the understanding of Washington’s pocket estuaries and salt marshes, and track green crab impacts.
