Disney's Animal Kingdom is 11 years old today! Construction began back in August 1995 with the grand opening on April 22 1998. The 500 acre park represents over 250 species of animals and over 3000 species of plants. More than 4 million trees were planted in the park before opening to create the dramatic visual backdrop of the park. Major additions to the park since opening include the land of Asia, Kali River Rapids, and most recently, Expedition Everest. According to recent unofficial attendance figures, Animal Kingdom brought in a record attendance for the park of 9.5 million guests in 2008.
