Commentary

Thank you for your report! European green crabs been present in Oregon since the late 1990s and researchers have been keeping an eye on them, but I don't believe there are any formal management plans in action. It seems to be that our native crabs keep them in check where their habitats overlap. Our recent warmer weathers have contributed to higher numbers of green crabs. Your report will contribute to these monitoring efforts. For more information here's a recent report on green crab status in Oregon, https://ir.library.oregonstate.edu/concern/technical_reports/rx913w156
