Princeton Ridge

Princeton Ridge

The Princeton Ridge is a unique ecological area in Mercer County that extends westward from the Millstone River and the Delaware & Raritan (D&R) Canal State Park across the northern part of Princeton Township into Hopewell.

For more than 50 years, the Ridge’s forest and wetland habitats have been identified as among the most important and environmentally sensitive areas in the region. Its mature forests are home to numerous endangered and threatened species, among them the Wood Turtle, Eastern Box Turtle, Cooper’s Hawk and Barred Owl.

New Jersey Conservation Foundation and its preservation partners are collaborating to create a “Princeton Ridge Preserve” linking existing preserved open space, including the Autumn Hill Reservation, Herrontown Woods Arboretum, and Smoyer and Hilltop Parks, to create an interconnected public preserve of natural areas. This preserve will be used for passive recreation and education, while protecting this environmentally sensitive region.

Recently preserved lands include the 10-acre Blumenthal property, the 4.3-acre Klepper property and the 14-acre Ricciardi property.

Princeton Ridge preservation partners include the Stony Brook-Millstone Watershed Association, Friends of Princeton Open Space, Kingston Greenways Association, Mercer County and Princeton Township.
