Natural History

Explore the waters Crane Wildlife Refuge on the Crane Estate by boat with the Trustees of Reservations! Join us for a cruise in Essex Bay aboard our pontoon boat the Osprey! We’ll view the seldom seen backside of the Crane Wildlife Refuge, and take a turn around Choate Island to view the open fields, wooded hillside and historic structures from the water.  

Take a closer look and explore the world of minuscule bugs! Learn together through hands-on activities designed to show you how to classify and identify these numerous and diverse creatures! Participate in activities in our incredible arthropods gallery. Observe and touch live invertebrates, and then go outside and collect some of your own. Dig in the dirt and learn how invertebrates help people compost food waste into soil. Create your own scientific equipment that will help you continue the study of entomology at home. All activities are designed to be fun and interactive experiences for elementary age students and their families to participate in together.

Join The Trustees of Reservations at Crane Wildlife Refuge on the Crane Estate in search of the American Toad in Ipswich, Massachusetts! Ever wonder what that screeching sound is on damp spring evenings? The cacophonous chorus of toads and Spring Peepers means winter is finally coming to an end. In the early evening darkness we’ll quietly make our way through the dunes to the bogs and puddles that serve as breeding pools for the American Toad, and hope to catch a glimpse of them (and other species too!) as they call to find a mate. These are the toads you most often see around your yard – but there’s a lot to learn about them! Come with us as we get up close and personal with these awesome amphibians!
