In the late 1880's, the Brooklyn Zoo was a menagerie--like many zoos during that time period. Animals were in relatively small areas and the zoo had few naturalistic exhibits. In the mid 1980's the zoo was closed down due to inhumane conditions. The Wildlife Conservation Society (WCS) and the City of New York worked together to transform the zoo with a $37 million renovation. Re-opened in 1993 by WCS, the Prospect Park Zoo contained exhibit areas where children could become involved with conserving wildlife. Today, the zoo is home to nearly 400 animals of more than 80 species. The exhibits are size-appropriate and mimic the animals' natural habitats. The barn pond is one of two man-made water bodies within the zoo. Its home to some of the waterfowl in the zoo's collection as well as turtles like red-eared sliders and even bullfrogs!
