Organization description: 

Teatown Lake Reservation is a private nonprofit membership organization that operates a nature preserve and education center in Westchester County, New York. Established in 1963 with 194-acre gift from the Gerard Swope, Sr. family, Teatown now comprises 1,000 acres with streams, waterfalls, hardwood swamps, mixed forests, meadowns, hemlock forests and laurel groves, with 15 miles of hiking trails open daily from dawn to dusk. Outdoor exhibits include 2-acre Wildflower Island with more than 230 species of wildflowers, Wildflower Woods, an outdoor classroom, a working maple sugar house, a bee & butterfly garden, a children's sensory garden, and a raptor loop featuring hawks, owls, kestrels and an eagle.


Programming includes: environmental education, stewardship of Teatown’s preserve, and regional conservation activities throughout the Hudson Valley. Education efforts include a wide range of classes, lectures, and outdoor activities, both on and offsite, for children, families, and adults – all focused on nature and the role of biodiversity in sustainable living.
