The Salish Sea is facing a serious challenge from invasive European green crabs, a species that threatens eelgrass beds, shellfish, and the overall health of our nearshore ecosystems. These crabs not only put native biodiversity at risk, but also jeopardize culturally and economically important resources like salmon and Dungeness crab.

Dawson’s graduate research at Western Washington University explores whether native river otters could help serve as a natural check on green crab populations. By studying otter diets and behavior, this work seeks to understand if these predators can play a role in reducing the spread of invasive crabs, complementing ongoing trapping efforts.

As a biologist with the Makah Tribe, Walker also leads estuarine monitoring and invasive species removal in Neah Bay. This work is grounded in collaboration, blending scientific research with the Tribe’s stewardship goals to protect treaty-reserved resources and strengthen the resilience of coastal ecosystems.

Together, these efforts highlight the importance of community-driven conservation—where science, cultural values, and hands-on stewardship come together to safeguard the future of the Salish Sea.
