IN THIS SECTION
We are New York’s National Estuarine Research Reserve. As part of a nationwide network of Reserves sponsored by the National Oceanic and Atmospheric Administration, we put federal funding, science, and tools to work on behalf of Hudson River communities and natural resources.

Our Sites
The Reserve protects nearly 5,000 acres of diverse tidal wetlands and upland habitat across four distinct sites in the Hudson River Estuary. These component sites serve as field laboratories for estuarine research, stewardship and education. Our sites include:
- Stockport Flats, in Columbia County
- Tivoli Bays, in Dutchess County
- Piermont Marsh, in Rockland County
- Iona Island, in Rockland County
Our Headquarters
Located on the banks of the Hudson River within Mills Norrie State Park, Norrie Point Environmental Center is home to the Reserve’s core programs, offering interpretive exhibits, classroom space, and educational programs to the public side-by-side with our research lab, weather station, and conference space for professional training programs.
Effective July 8, 2026, Norrie Point Environmental Center will be temporarily closed for renovations. Visit the FAQ page for details about building access and programming changes.
Our Staff
Our people are the foundation of our programs, from education to outreach and training to stewardship and restoration. Reserve staff are responsible for the research and monitoring efforts that inform all of our programs, and coordinate the many public events and workshops held at the Reserve.
Our Partners
The Reserve is part of the National Estuarine Research Reserve System, which includes 31 reserves representing different biogeographic regions. The Reserve was designated in 1982, operates as a partnership between New York State and the National Oceanic and Atmospheric Administration (NOAA), and relates to four federally-designated and state-protected sites along 100 miles of the Estuary.
We often partner with other organizations on the federal, state, local, and nonprofit level. Interested in partnering with us? Get in touch.
