Our science and stewardship mission is to conserve our region’s biodiversity, while creating an environment for exceptional educational opportunities.

Biodiversity is the variety of life on earth, including plants, animals and microorganisms.

To keep our ecosystems healthy, we must commit to supporting the plants, animals, and other organisms that call them home.

Our preserve’s greatest threats

  • Overpopulated deer

    threaten the future of our forests

  • Invasive Species

    displace native populations of plants and animals

  • Chemical runoff

    alters wetland ecosystems and quickens lake fill-in

  • Climate change

    shifts natural cycles on both global and local scales

Bats of Westchester

Bats of Westchester

Have you looked into the twilight sky and seen the quick, agile silhouettes of bats in flight? For some it can be frightening to see bats nearby, but take heart that these amazing little hunters use their keen eyesight and powerful echolocation to find prey and stay away from humans! While there are 1,400 species of bats in the world, only 9 call New York home. Do you know your bat neighbors?
