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

Teatown Statement on Disposition of the Croft

We are sharing the documents on this page so that you may better understand our organizational process, conducted over many years, that led to the decision by Teatown’s Board of Trustees on the disposition of the Croft. A number of interested parties – architects, builders, potential buyers – were given access to the Croft house to aid us in our consideration.
