Olympia Oysters Protocol


Olympia oysters, the only native oyster species on the west coast of North America, provide unique habitat structure for other organisms. However, their current distribution is greatly reduced relative to their historic distribution. Monitoring Olympia oyster populations helps with planning conservation & restoration actions.

The recommended protocol is based on work by the Puget Sound Restoration Fund. Also see their Olympia Oyster Field Guide, and the WDFW Plan for Rebuilding Olympia Oyster Populations.
