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 Will Starkey (wstarkey@teatown.org) with any questions.


Struggling Through Sap Season

Struggling Through Sap Season

The coming of spring at Teatown is usually heralded by a successful sugaring season. We gave Warren’s Sugar House a thorough scrub down in early February, dutifully set up and sanitized our evaporator pans, and tapped trees before Presidents’ Day. We thrilled to the gentle “tink, tink, tink” of sap falling in our buckets, but a few good days do not a successful sugaring season make.

The Great Backyard Bird Count

The Great Backyard Bird Count

When you picture a birder, what comes to mind? If you’ve seen the 2011 caper The Big Year, you might imagine an older white man (Steve Martin, is that you?), obsessively focused on growing his life list, ticking off species in far-flung destinations all over the world. Your mental birder might be toting a pair of binoculars, carrying a camera with a lens longer than he is tall, and is probably wearing a tactical vest.
