Biological Invasions: How Species Become Invasive and Impact Salish Sea Shorelines 

 Presented by Emily Grason, PhD

Natural processes and mechanisms enable living organisms to move into new habitats where they compete with both native species and others already present. The success, impacts, and long-term effects of these introduced populations determine whether or not they become invasive species. Dr. Grason will illustrate these potentially environment-changing processes with real-time examples.

Emily Grason, PhD, studies ecological interactions through the lens of non-native species. She is an aquatic invasions specialist and the Crab Team program coordinator with Washington Sea Grant, College of the Environment, University of Washington. Dr. Grason has worked with local scientists and volunteer citizen scientists in pocket estuaries and salt marshes on detection, monitoring, and control of the European green crab. She holds a master’s degree in biology from Western Washington University and ain biology from the University of Washington.
