Friends of Cortes Island is working in partnership with Klahoose Guardians and the Department of Fisheries and Ocean (DFO) to monitor for the invasive European Green Crab in Mansons Lagoon.

We are carrying out a monthly trapping exercise in the lagoon. So far this year we have not found any European Green Crabs, which is good news. However, several were found last year through the same trapping exercise, and we are very concerned about them becoming established here.

European Green Crabs are considered one of the world’s worst invasive species. They can significantly damage shoreline ecosystems and harm native species and habitats including eelgrass beds.

We are asking the community to help keep watch for them and to take measures to prevent their spread.

How you can help

IDENTIFY: Take a look at the attached brochure to learn how to correctly identify European Green Crabs, and keep your eyes open when you are on the beach. Remember that there are many types of crabs that are green in colour, but only the European Green Crab has 5 spines. Please do not kill any crabs.

REPORT: If you think you have found a European Green Crab, please email a photo, date of observation and the location to DFO.AISPacific-EAEPacifique.MPOdfo-mpo.gc.ca Please also report it to either FOCI – tel 250 935 0087 or Klahoose Guardians tel 250-935-6536 Ext.229 so we can hopefully come out to confirm the identification and handle any green crabs found.

CLEAN, DRAIN, DRY Help stop the spread of invasive species: Please ensure you are not transporting European Green Crabs (or their larvae) from one location to another. Completely clean, drain and dry your boats and gear before moving them.

VOLUNTEER. If you would like to volunteer to help with the monthly trapping exercise, please contact us at friendsofcortesgmail.com
