Jersey Zoological Park or Jersey Zoo is a 25-acre (10 ha) zoological park established in 1959 on the island of Jersey in the English Channel by naturalist and author Gerald Durrell (1925–1995). It is now officially called Durrell Wildlife Conservation Trust after its founder, or Durrell for short. It has approximately 150,000 visitors per year, despite a lack of emphasis on large animals and its relatively out-of-the-way location; visitor numbers tend to vary with the tourist trade to Jersey. Jersey Zoo has always concentrated on rare and endangered species. It has mammals, birds, amphibians and reptiles, comprising over 190 species. Since 1964, the zoo has been home to the Durrell Wildlife Conservation Trust (formerly the Jersey Wildlife Preservation Trust).
