Nature Sightings

Welcome to the Nature Sightings section of our website. Here, we post nature sightings that have been reported to us throughout the Sudbury, Assabet and Concord Rivers Valley. Sudbury Valley Trustees is also continuing the work of the Wildlife Trails Education Project and will post pictures taken from our automatically triggered cameras. If you have an interesting sighting or a picture you would like to share e-mail Dan Stimson.
