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

Cindy’s Garden is Getting a Makeover!

Cindy’s Garden is Getting a Makeover!

In 2010, a children’s garden was dedicated to the memory of Cindy O’Hanley, a cherished volunteer Nature Guide and leader of Teatown’s Little Tree Huggers and Knee Hi Nature groups. “Mrs. O” shared her love of nature and, especially, plants with many budding naturalists. By 2018, the wood used to build the raised beds and the bench were succumbing to rot.

The Humble Hackberry

The Humble Hackberry

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!
