| Notes | The COVID-19 pandemic affected this report, leading to combined years and trapping on a reduced number of estuaries. The invasive European green crab is a voracious predator of bivalve molluscs, small crustaceans and other organisms. It has been present in Oregon since the late 1990s. The population grows when winter waters are warm, as they are during El Niños. Since 2015, however, “recruitment has been good every year. Since green crabs live for 6 years, these recent strong year classes can produce larvae until 2027. . . Now that populations in Oregon, Washington and British Columbia have built up, we have evidence for local production and for larvae sources from a genetically distinct population on Vancouver Island. . .” (from the Executive Summary) This report is accompanied by a dataset, available at: https://ir.library.oregonstate.edu/concern/datasets/b8515w17z |
