Tracking Dungeness Crab Across the Salish Sea

Community science for crabs

Driven by communities and led by the Hakai Institute, Sentinels of Change is a decade-long project that uses light traps to investigate the ecology and dynamics of a critically important species in our inland sea: Dungeness crab.

The first year of our project had one trap on the Sunshine Coast within a network that spanned the Salish Sea. This year there are three more (does Gibsons count?). Throughout the spring and summer, groups of dedicated volunteers check the traps regularly and watch the crabs (and other species) come and go.

Join us to hear about our findings so far and how important community science is in our efforts to understand ecosystems and environmental change.
