The East Brunswick Butterfly Park is the first municipal park in New Jersey, and perhaps the country, dedicated o the conservation and enjoyment of butterflies. The park consists of an 11-acre preserve adjacent to Great Oak Park and features a 1,000-foot long cinder trail lined by numerous plantings to attract butterflies, a 400-foot long meadow trail, 1,000 feet of woodland trails, an early successional field that is being managed to control invasive shrubs and to promote wildflowers and grasses and second-growth upland woods being manage for invasive species. All trails feature benches and signs. The park is also located along the township bike path and a bike rack is provided at the entrance near Great Oak Park. The park provides habitat for a wide diversity of wildlife species, including butterflies, and offers abundant opportunities for nature study and enjoyment. The park is an ongoing project of the East Brunswick Environmental Commission and the Friends and has been constructed primarily through volunteer efforts and donations. Field guides and butterfly nets are available for public use at the entrance to the park, near the kiosk. Abundant opportunities exist for individuals and groups to assist with the park.
