Topic: European Green Crabs in Oregon: are they now established?
Why are we only now seeing European green crabs in Oregon estuaries, when this invader has been present for well over 20 years? Prior to the Ocean Heat Wave and the Ell Niño of 2014-2016, green crabs in Oregon were rare and larvae only recruited from the south, and only during warm winters. In the last few years, however, recruitment has been good and numbers in Oregon estuaries have steadily increased. Is the population now large enough to be self-maintaining, and/or are we also getting recruitment from the north? Future research is aimed to answer these questions.
