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

The common hackberry (Celtis occidentalis) is an understated and unsung hero of the local landscape. Beautiful, hardy, and beneficial—this tree offers much to the homeowner, city dweller, and wild creatures alike!

The butterfly bush attracts great spangled fritillary and monarch butterflies that land and flutter like showy baubles. Before the monarchs move south on their long journey to Mexico, Teatown educators join thousands of other citizen scientist volunteers across the country that catch, tag, and release monarchs as part of Monarch Watch.
