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

Skunk Cabbage – The True Sign of Spring

In the wetland below the cliffs, observed through the remains of the snow and ice, the burgundy-rimmed horns, scattered about, signal the change of season. The curved mottled spathe provides a hood for the rounded spadix peeping from within, which bears indistinct petal-less flowers with both stamens and pistils.
