About San Francisco Zoo

San Francisco Zoo and Gardens

The San Francisco Zoo and Gardens, commonly known as the SF Zoo, is a 100-acre zoological park situated in the southwestern corner of San Francisco, between Lake Merced and the Pacific Ocean. Its main entrance is located on the ocean side along the Great Highway. The zoo is owned by the San Francisco Recreation & Parks Department and operated by the San Francisco Zoological Society, a non-profit 501(c)(3) organization, under a public-private partnership established in 1993.

History and Development

Planning for the zoo commenced in 1929, on land adjacent to the historic Fleishhacker Pool. The site was already home to a children's zoo, a carousel, and the Mother's Building. Initial exhibits, constructed in the 1930s, included Monkey Island, Lion House, and Elephant House, featuring some of the first bar-less enclosures in the United States. Over the decades, the San Francisco Zoological Society has played a crucial role in fundraising and supporting the zoo's development, contributing to projects such as the renovation of the Children's Zoo and the establishment of the Avian Conservation Center.

Animals and Exhibits

As of 2016, the San Francisco Zoo housed over one thousand individual animals, representing more than 250 species. The zoo is organized into various regions, including the Leanne B. Roberts African Savanna, the Jones Family Gorilla Preserve, the Madagascar Center with the Lipman Family Lemur Forest, the Pacific Rim, Australia, The Americas, and the Exploration Zone. Notable residents have included Koko the gorilla, the birthplace of whom is at the zoo, and Elly, for many years the oldest black rhinoceros in North America. In April 2024, an agreement was announced to bring giant pandas from China to the zoo.

Conservation Initiatives

The San Francisco Zoo is actively involved in wildlife conservation through its participation in over 30 Species Survival Plans (SSPs) sponsored by the Association of Zoos and Aquariums. These programs aim to maintain healthy, genetically diverse, and demographically stable populations of endangered and threatened species. The zoo has also undertaken rescue and rehabilitation efforts for animals like orphaned black bears and a blind California sea lion.

Challenges and Criticisms

In recent years, the San Francisco Zoo has faced significant scrutiny regarding its facilities and animal welfare. A 2024 report by the San Francisco Animal Control and Welfare Commission described the facility as "extremely outdated" and "unsafe." The zoo has also experienced several safety incidents, including a tiger escape in 2007 that led to a visitor fatality, and a gorilla death in 2014 due to a door malfunction. Management decisions and the allocation of bond funds have also drawn criticism from employees, union members, and animal welfare advocates, with concerns raised about animal care practices and the overall condition of the zoo.
