Freshwater Mussel Monitoring Training: Learn to Survey These Silent Streamkeepers

Join us for our third training to explore the essential role of freshwater mussels in stream ecosystems and salmon recovery!

Freshwater mussels are ecosystem engineers—they filter and clean our waterways, stabilize streambeds, and support healthy salmonid habitat by improving water quality and clarity. Their presence (or absence) tells us a lot about the overall health of our watersheds.

Thanks for your interest, this event is full.

At this training, you’ll learn how to:

• Identify Native mussel species and the newest Oregon Conservation Strategy addition—fingernail clams

• Conduct mussel surveys and apply salvage protocols

• Understand mussels’ crucial role in salmon ecosystems and as indicators of aquatic health

Whether you’re a community scientist, restoration practitioner, or curious naturalist, this training will give you the tools to contribute to meaningful mussel conservation.

This event is open to participants age 16 and older. This is a classroom training, with upcoming field surveying dates announced at the end of the session to put the skills to practice.
