We need your help! Volunteers are needed to help with planting, monitoring, and maintaining our sites. Community workdays are fun and interesting ways to learn more about our streams while helping bring them to life.

All ages are welcome! Children under 12 must be accompanied with an adult.

Skilled volunteers

We are seeking help with several scientific studies we’re undertaking that will evaluate alternative planting and vegetation management techniques, track indicators of ecosystem health, and assess changes over time in how people are using streamside environments. We’re especially looking for expert birders, people with strong knowledge of native plants, and anyone with experience in field data collection. If you’d like to be involved, email us with a brief description of your background and interests!


All state and local requirements pertaining to COVID-19 will be followed. If you have a fever or other symptoms of COVID-19, think you may have been exposed to someone with COVID-19, or have a pending COVID-19 test, we ask that you refrain from attending the event. All activities will be held outdoors. Staff will have hand sanitizer available and will structure the event to encourage adequate spacing, but consider bringing/wearing a mask for times where there may be close contact with others who may not be fully vaccinated.
