The Harold H. Malkmes Wildlife Education and Ecology Center is a park, zoo, and ecology site in Holtsville, New York and operated by the Town of Brookhaven, and located on the site of a former landfill. The official address is 249 Buckley Road, although some of the land owned by the site extends along Blue Point Road and as far south as Woodside Avenue.
The site of the Ecology Center was once a general dump owned by New York State, and was acquired by the Town of Brookhaven in 1937 for use as a town dump. Prior to this, the right of way for the Suffolk Traction Company trolley line also ran through this location. In 1968, the State Environmental Facilities Corporation converted the site into a sanitary landfill with seepage lagoons, and closed the facility completely by 1974. By 1971, the park was already under development, and opened in 1979.
