Community called to action after European Green Crab detected on Orcas

||| FROM JESS NEWLEY for FRIENDS OF THE SAN JUANS |||

A European green crab molt was recently discovered at Crescent Beach by Amy Sprenger’s middle school science class. The finding marks another important detection in ongoing efforts to monitor for the highly invasive species in the San Juan Islands.

Following the molt discovery, the Washington Department of Fish and Wildlife conducted rapid response trapping efforts and confirmed the presence of a live adult male European green crab in Deer Harbor. European green crabs are considered one of the world’s most invasive marine species, posing significant threats to eelgrass, shellfish, and nearshore ecosystems.

In response, Friends of the San Juans, SJC Conservation Land Bank, and partners are inviting Orcas Island residents to become part of the early detection network through a free Molt Search training on Friday, June 26. Participants will learn how to identify green crab molts, monitor local shorelines, and contribute valuable data that helps protect island ecosystems.

“These detections demonstrate how important community science can be,” said Jess Newley, Community Science and Education Director at Friends of the San Juans. “A single molt found by a trained volunteer can trigger a rapid response and provide critical information for protecting our marine environment.”

The training is open to all ages and experience levels. Bring some boots, molt collection devices, and enthusiasm for protecting this place! Community members interested in helping monitor local beaches are encouraged to attend.
