Indian Island Marine Health Observatory

Indian Island Marine Health Observatory (Orcas Island) monitors a rocky two-acre island (part of the San Juan Islands National Monument) surrounded by beaches and eelgrass meadows, accessible during low tides from the town of Eastsound.  Data is collected on the abundance of key indicator species living on and beneath the rocks (starfish, sea anemones, sea slugs, crabs) as well as fish species found in the eelgrass meadows.  Eelgrass shoot-density, the diversity and age class distribution of infaunal bivalve species buried in beach sands, and contaminant concentrations in bivalves are measured annually.  Seabird use of the island is also monitored together with flowering times of native plants.  Weekly sampling and a public hotline (360 468-48469) track plankton communities and potentially toxic phytoplankton blooms, sharing data with NOAA's SoundToxins program.  An annual fall event, Celebrate Indian Island, shares monitoring results, music, food and art with the community.

A special field guide to marine life at Indian Island is available at local stores, and volunteer naturalists provide guidance on the beach for school groups and over 4,000 visitors annually, as well as trails and signs to separate human activity from seabird nests and fragile flower meadows. Nearby Skull Island, also part of the National Monument, is monitored and interpreted by this program as well.  See our Calendar for dates of public activities.
