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 were preserved by the County of Middlesex and the Township of Plainsboro that supports a diversity of habitats and wildlife, with one of the largest lakes in the area.

New Jersey Audubon manages the Preserve and Nature Center, providing year round environmental education opportunities for the local community. The Preserve is a lasting ecological legacy for current and future generations. The Nature Center houses a variety of exhibits, live animals, a reference library, a Nature Store, and several miles of trails.

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 including the majestic southern Twayblade orchid. In addition to the trails, we are running programs on some weekends.
