Our American heritage

The Hudson River Valley, with its rich history and unparalleled beauty, is a place worth protecting. This region is a recreational playground for the 2.5 million residents that call the valley home.

We have been working in the Hudson River Valley for more than 40 years, protecting more than 80,000 acres including important farmland, recreational, and historic lands.

Whether it is a viewshed from a historic site, a prime recreation trail that leads to a ridgetop overlook, or a pastoral farm that has been cultivated for generations, we are protecting the open spaces of this truly American landscape.

Protecting a national heritage

The Hudson River Valley is one of 40 National Heritage Areas in the United States, as designated by Congress in 1996 in recognition of the significant history of the region’s landscapes.

To date, we have:

  • Acquired over 17,000 acres to create Sterling Forest State Park
  • Increased the size of Fahnestock State Park by more than 50 percent
  • Created the Schunnemunk Mountain State Park and given it to New York State

Rich in history, the valley contains:

  • Five National Historic Sites
  • 58 National Historic Landmarks
  • 89 historic districts
  • Over 1,000 sites listed on the National Register of Historic Places.

Additionally, the lands of the Hudson River Valley provide 900,000 acres of farmland for 2,500 full-time farms.
