Rick Roth & Cape Ann Vernal Pond Team: Introduction to vernal pools. Join us to learn all about vernal pools as Rick Roth and the Cape Ann Vernal Pond Team share their knowledge and enthusiasm with us! They will bring exhibits of the living things found in our local vernal pools & show us some of the critters that rely on this critical wetland habitat. Learn about the three obligate species - spotted salamanders, wood frogs and fairy shrimp that are found on Cape Ann. No registration is needed. This event will be at our 21 Main Street location.
