The Hudson River National Estuarine Research Reserve’s mission is to improve the health and resilience of the Hudson River Estuary by conserving estuarine habitats through integrated education, training, stewardship, restoration, monitoring, and research programs.

The Estuarine Research Reserve assist the Hudson River Estuary Program with implementing the Hudson River Estuary Action Agenda—a conservation and restoration blueprint for a strong, vibrant, healthy estuary and watershed.

The Reserve protects nearly 5,000 acre 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

As part of a nationwide network of Reserves sponsored by the National Oceanic and Atmospheric Administration, Hudson River National Estuarine Research Reserve puts federal funding, science, and tools to work on behalf of Hudson River communities and natural resources.
