Monitoring

Friday Harbor Marine Health Observatory  monitors San Juan County’s busiest urban waterfront including its largest marina and ferry terminal in cooperation with the Port of Friday Harbor. Abundance of key indicator species (starfish, sea anemones, tunicates, crabs) is recorded seasonally at fixed locations on the docks including fresh floats and pilings.

Trend analysis is available to download from the past five years of monitoring. This includes extensive data of how many key indicator species take up residence at the port and when.
