The European green crab is spreading rapidly along the Pacific Coast, threatening ecosystems and aquaculture. In this webinar, three experts will share new research on how we can better understand and manage this invasive species.

• Abby Keller (UC Berkeley) will explore how decision theory can guide when to try to remove green crabs—or when to adapt to their presence—as populations grow beyond control.
• Mary Fisher (UC Davis) will present research from Willapa Bay, WA, using DNA metabarcoding tools to uncover what green crabs are eating and how their diet differs between aquaculture sites and natural habitats.
• Rikke Jeppesen (Elkhorn Slough National Estuarine Research Reserve) will share findings on how native sea otters may help keep green crab populations in check in California estuaries.

This webinar is a great opportunity for anyone interested in invasive species, coastal ecosystems, and science-based management. This webinar is being jointly hosted by NAISMA and Sea Grant.
