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

Regional Collaboration

We understand that partnership is key to a sustainable future. Learn more about our partnerships with local organizations.

Invasive species are one the biggest threats affecting biodiversity today. At Teatown we are working to control and remove invasive plants, but the problem is too widespread for us to handle alone; we rely on the help from volunteers to keep this problem in check. Join our Stewardship crew as we remove different invasive species, discuss how to identify them as well making educated management decisions.

We will be working outside, please wear proper attire and footwear. Gloves and tools will be provided.

All ages are welcome. In the event of bad weather, the event will be canceled, and you will be notified via email the day before.

Reach out to Mathew McDowell (mmcdowell@teatown.org) with any questions.

Fat and Sassy Goats

Fat and Sassy Goats

There are many ways to battle the various invasive plants that are found throughout Westchester County. One extremely effective way is ecologically prescribed goat grazing. We were lucky to work with the local herd Fat and Sassy Goats for two weeks up at our Cliffdale fields – the herd of 85+ grazing goats hired to munch through the invasive vegetation and convert it into nitrogen-rich pellets, helping to transform this area of the preserve and give nature the boost it needs to reset the land.
