Never in my wildest dreams did I ever think I would be excited about eels. Until, that is, the night I heard on Channel 12 about the Hudson River Eel Project.
Science & Stewardship
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 Rebecca Policello (rpolicello@teatown.org) with any questions.

Northern Westchester Butterfly Count
An annual rite of summer, the North American Butterfly Count is a way for butterfly enthusiasts across the country to partake in a citizen science monitoring effort. Our resident butterfly enthusiast Charlie Roberto has been leading butterfly count walks at Teatown since 1995 to educate and encourage visitors to partake in this important effort.
