The mission of our science and stewardship efforts is to preserve our region’s biodiversity.

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 and animals 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
