The Bronx Zoo is located in the Bronx borough of New York City, within Bronx Park. It is the largest metropolitan zoo in the United States, comprising 265 acres (107 ha) of park lands and naturalistic habitats, through which the Bronx River flows.
Fordham University owned most of the land which became the Bronx Zoo and New York Botanical Garden. Fordham sold it to the City of New York for only $1,000 under the condition that the lands be used for a zoo and garden; this was in order to create a natural buffer between the university grounds and the urban expansion that was nearing. In the 1880s, New York State set aside the land for future development as parks. In 1895, New York State chartered the New York Zoological Society (later renamed to Wildlife Conservation Society) for the purpose of founding a zoo.
The zoo (originally called the Bronx Zoological Park and the Bronx Zoological Gardens) opened its doors to the public on November 8, 1899, featuring 843 animals in 22 exhibits. The first zoo director was William Temple Hornaday.[6] Heins & LaFarge designed the original permanent buildings as a series of Beaux-Arts pavilions grouped around the large circular sea lion pool. In 1934, the Rainey Memorial Gates, designed by noted sculptor Paul Manship, were dedicated as a memorial to noted big game hunter Paul James Rainey. The gates were listed on theNational Register of Historic Places in 1972.
In November 2006, the Zoo opened up brand-new eco-friendly restrooms outside the Bronx River Gate. According to the Clivus multrum company, which built the composting toilets chosen by the Zoo, these facilities will service 500,000 people and save 1,000,000 U.S. gallons (3,800,000 l) of water a year.
In March 2007, the Wildlife Conservation Society and the Fordham University Graduate School of Education announced they would offer a joint program leading to a Master of Science degree in education and New York State initial teacher certification in adolescent science education (biology grades 7-12). The program began in 2008, and is the first joint degree program of its kind.
