'Nature’s Engineers’ at Thacher Nature Center on Saturday, Nov. 3, at 3:30 p.m. Beavers are famously busy animals with the unique ability to create their own habitats! Come learn more about the many adaptations that allow beavers to redesign entire ecosystems and survive the winter! After an indoor presentation, we will visit a nearby beaver lodge in hopes of catching a beaver or two in action! This program is appropriate for adults and children 7 years and older. Please call 518-872-0800 to register.
