In addition, the zoo’s focus shifted from simply showing animals to establishing programs to help ensure their futures. It wasn’t until the late 1950’s when the zoo’s first full-time veterinarian was employed! In 1958, Friends of the National Zoo (FONZ) was founded in an effort to shift the economic burden of supporting the zoo to the Smithsonian Institute. This enabled the zoo to obtain the funding it needed to grow and develop. Today, FONZ has 40,000 contributing members.
Soon, the National Zoo became more than just a popular tourist destination — it became a center of research, education, science, and breeding biology. In 1972, the National Zoo exhibited its flagship species, the Giant Panda, for the first time. In 1975, the zoo bought 3,200 acres near Front Royal, Virginia where rare animals such as the Maned Wolf and Mongolian Wild Horses are free to live in endless enclosures (围场) where biologists carefully study their habits, behaviors, biological needs, and breeding success.
Today, the National Zoo is an incredible experience for people of all ages. It features amazing animal exhibitions. Visitors can experience the wonders of the Amazon Rainforest and view rare animals from there. Numerous endangered species are exhibited in the zoo.
