The Plainsboro Preserve is a cooperative project between the County of Middlesex, Township of Plainsboro and New Jersey Audubon Society. In 1999, 530 acres of land formerly owned by the Turkey Island Corporation and Walker Gordon Laboratory Company were acquired by the County and Township. Middlesex County purchased and owns 401 acres and provided a grant to the Township of Plainsboro for the purchase of an additional 126 acres. In 2003, the County purchased 126 acres of the former Perrine Tract to add to the Preserve. The Township added additional land to grow the Preserve and currently maintains responsibility for management of the County-owned portions.
At over 1,000 acres, the Preserve supports a diverse array of habitats and the 50-acre McCormak Lake, with over five miles of hiking trails for hikers, birdwatchers and nature enthusiasts. The New Jersey Audubon Society manages the Preserve and a 6500 square-foot environmental education center, providing year-round environmental education opportunities.
