The Plainsboro Preserve is a collaboration with the Township of Plainsboro, the County of Middlesex, and New Jersey Audubon. Close to 1,000 acres of lands preserved by the County of Middlesex and the Township of Plainsboro support a diversity of habitats and wildlife, with one of the largest lakes in the area. The Preserve is a natural jewel for residents and visitors to the area and an ecological legacy for future generations.
New Jersey Audubon operates the Preserve’s Rush Holt Environmental Center from April through October, with the Township operating the Center from November through March. There are environmental education programs, nature experiences, and recreational offerings throughout the seasons. The Center houses program space, a variety of exhibits, live animals and a reference library.
Enjoy over five miles of trails meandering through mature beech woods, wet meadows, and the shoreline of scenic 50-acre McCormack Lake. Walk the floodplain of Devil’s Brook in search of the more than 150 species of birds that call the Preserve home during the year. Plants on site consist of a diverse showing of spring wildflowers and also include over ten species of rare or endangered plant species found sparingly elsewhere in the state.
NOTE: Deer Management Program in Progress
The Township of Plainsboro is conducting a managed deer harvest program from mid-September through mid-February. The hunt is consistent with the New Jersey Department of Environmental Protection’s policies and rules. Click HERE for more information.
