The Oregon Zoo, formerly the Washington Park Zoo, is a zoo in Portland, the largest city in the U.S. state of Oregon. Located southwest of Downtown Portland, the zoo is inside Portland’s Washington Park, and includes the narrow gauge Washington Park & Zoo Railway that connects to the International Rose Test Garden inside the park. Opened in 1888 after a private animal collector donated his animals to the City of Portland, the zoo is now owned by the regional Metro government. A member of the Association of Zoos and Aquariums, it has species survival plans for twenty-one endangered/threatened species, among which are successful breeding programs for endangered California condors, Asian elephants, and in recent times, African lions too. (The latter was under recommendation by the AZA). The zoo also boasts an extensive plant collection throughout its animal exhibits and specialized gardens. During the summer it is host to a concert series, and in the winter produces ZooLights, a holiday light show. The Oregon Zoo is Oregon’s largest paid and arguably most popular attraction, with more than 1.6 million visitors in 2008 to 2009.
