Wegeforth, the organization claims the largest zoological society membership in the world, with more than 250,000 member households and 130,000 child memberships, representing more than half a million people. The San Diego Zoo and San Diego Zoo Safari Park feature a combined 15,000 animals of 750 species, not all of which are displayed publicly. In its first few decades, the Zoological Society of San Diego worked to establish and build up the San Diego Zoo. Members of the organization formed groups that later became the

from one of the Exposition's exhibits:
On September 16, 1916, as I was returning to my office after performing an operation at the St. Joseph Hospital, I drove down Sixth Avenue and heard the roaring of the lions in the cages at the Exposition then being held in Balboa Park. I turned to my brother, Paul, who was riding with me, and half jokingly, half wishfully, said "Wouldn't it be splendid if San Diego had a zoo! You know...I think I'll start one." Taking me at my word, he replied that he would be glad to help me but added dubiously that he did not see how such a project could be put over on the heels of an Exposition not very successful in its second year. I had long nurtured the thought of a San Diego Zoo and now—suddenly—I decided to try to establish one.Wegeforth and Morgan, p. 71.

Establishing the San Diego Zoo

The Zoological Society's initial efforts focused on the creation of the San Diego Zoo. In January 1917 the Balboa Park Board agreed to furnish quarters in the park to establish a zoo, and to assist the society with maintenance. The Zoo began as a long row of animal homes along Park Boulevard ("little more than Menagerie Row", according to WegeforthWegeforth and Morgan, p. 73.) for animals that had been rented for the Panama–California Exposition from a

). The society faced financial challenges in maintaining the growing number of animals in their care. W. H. Porterfield of the ''San Diego Sun'' had long been interested in establishing a zoo in Balboa Park, and offered to use his newspaper to publicize the Zoo and campaign for funds. At his suggestion, the society's board of directors contacted school authorities, asking them to stimulate children to approach their parents about supporting the Zoo. Porterfield ran a contest in the ''Sun'' in conjunction with an upcoming

He also arranged for the circus to charge children a $0.50 admission fee which would include a membership to the Junior Zoological Society; $0.12 of each admission would go to the circus, and the remaining $0.38 to the Zoological Society. Within two months the society had raised enough money to purchase the Wonderland animals from the Mission Bay Corporation. Carl H. Heilbron and David Charles Collier were also instrumental in helping the Zoo acquire the Wonderland animals. Joseph Thompson planned much of the Zoo's education program, which included guidebooks, textbooks, and free lectures; the first such lecture was about

By this time the Zoological Society was selling annual memberships at $5 apiece.

. Following a suggestion made by the city attorney, a resolution was adopted in 1918: In return for a building in Balboa Park and an as-yet-undesignated plot of ground set aside for the Zoo and for research work, the society would sell ownership of all its wildlife, equipment, and property to the Board of Park Commissioners of the City of San Diego; thus the Zoo and all its future assets would belong to the city, but would be managed and maintained by the Zoological Society, who would have jurisdiction over the permanent zoo site. "Then the Zoological Society would not legally own either the land or the animals but would be the administrative body for the Zoo," wrote Wegeforth, "retaining the right to sell or trade whatever surplus animals we deemed unnecessary for exhibition."Wegeforth and Morgan, p. 80. The City Council agreed, and pledged additional funds to aid the Zoo's maintenance. In July 1918 Harry Wegeforth resigned from the board of directors to accept a commission with the

By 1921 the City Council appropriated $5,000 for maintenance and improvements to the Zoo, and the Zoo's current site, an area of 140 acres, was approved that fall as its permanent location.Wegeforth and Morgan, p. 87. City planner Nathanial Slaymaker drew up the initial plans for the site. Wegeforth convinced many notable San Diegans to help fund the Zoo's construction, including Scripps, John D. Spreckels, George Marston, and Ralph Granger (of Granger Hall). Scripps donated $9,000 for a fence around the property, which for the first time enabled the Zoo to charge an admission fee.Wegeforth and Morgan, p. 114. A formal dedication of the property was held, and much of 1922 was spent hiring staff, building exhibits and pools, and acquiring new animals, including the first live

1920s–1930s

In the decades after the San Diego Zoo's opening, the Zoological Society of San Diego focused on expanding the Zoo and its reputation. ''Zoonooz'' first appeared as a column in the ''San Diego Sun'' in 1924, written by W.B. France; in 1926 he granted the

title to the society, who expanded it into a bi-monthly magazine that was free to Society members. To this day, membership in the San Diego Zoo Wildlife Alliance includes a subscription to the member magazine, which has now expanded to digital distribution as well as print and has been renamed the San Diego Zoo Wildlife Alliance Journal. In April 1924 Wegeforth created the National Association of Zoological Executives (NAZE), an affiliate of the American Institute of Park Directors, to bring together zoo directors from around the country to exchange information and animals so they would not have to go through animal dealers.Wegeforth and Morgan, pp. 107–108. "It seemed preposterous to me", he wrote, "that a group of intelligent zoo directors could not get together and work out a plan whereby they would all know what surplus stock each had available. This thought blossomed in my mind: to have them contact foreign zoos for their mutual benefit, relative to importing such animals as they wanted. And that led me logically to the hope that a number of zoos would collaborate on expeditions, prorating the animals among them ..In addition to saving affiliated zoos tidy sums by eliminating the middlemen, the discussions and exchange of experiences proved of inestimable value." In 1966 NAZE became the American Association of Zoological Parks and Aquariums (AAZPA), a branch of the

In 1926 O'Rourke resigned from the board of directors, denied his gift of the Nevada building to the society, and incorporated his own O'Rourke Institute as an educational institution, with Raymenton in possession of the building.Wegeforth and Morgan, p. 127. In a 1928 issue of ''Zoonooz'', the society accused Raymenton of plotting "to seize the organization and exploit it as his own" and O'Rourke of attempting to split the junior and senior branches of the society. The society argued that the 1918 resolution gave them jurisdiction and control over the Zoo grounds, including any buildings within; city authorities agreed, and returned control of the building to the society in 1939.Wegeforth and Morgan, p. 134. In 1926 Ellen Browning Scripps donated $50,000 to the society to build a Hospital and Biological Research Institute, which opened the following year.

She also served as president of the AAZPA from 1949 to 1950. Remarking on the role of the society in relation to the Zoo in 1934, she stated "The chief function of the Zoological Society is to maintain public interest in the Zoo at all times and to prevent its being used as a political cat's paw by unscrupulous politicians."

"That the Zoo survived the first, hysterical months after Pearl Harbor—economically and personnel-wise—was due to careful planning and organization and strong leadership", wrote San Diego author and journalist Neil Morgan. "Zoos and parks throughout the West Coast were hard-hit by the war scare, and some others were closed." Though attendance at the Zoo dropped after the outbreak of the war, it rose dramatically through the rest of the decade, averaging 500,000–600,000 visitors annually as San Diego's population boomed due to the presence of many military installations and defense manufacturers, and topping 800,000 by 1948. A visit to the Zoo by officials of the New York Zoological Society in 1944 earned praise from its president, Henry Fairfield Osborn, Jr., particularly for the Biological Research Institute and Zoological Hospital.Wegeforth and Morgan, pp. 152–153.

Establishing the Wild Animal Park

In the late 1950s, Dr. Charles Schroeder, who had replaced Belle Benchley as Director of the San Diego Zoo after her retirement, had the idea to develop a "country zoo", an expansive animal farm where rare and endangered animals could be relocated from the somewhat-crowded Zoo and have space to roam, which would encourage breeding. He began searching for a suitable location in 1959, envisioning a facility with few public amenities and estimating the cost of construction at $1 million. The Zoological Society's board of directors opposed the idea, saying it would be too costly, and some even threatened to fire Schroeder if he did not drop the subject. Schroeder persisted, however, and a site in San Diego's

The 67th annual AAZPA conference was hosted by the Zoological Society in 1991. In 1993 the society was one of only five zoological institutions in the United States to receive American Museum Accreditation. 1998 saw the adoption of a new strategic plan involving renovating older exhibits and building new ones. The society hosted the second annual Animal Behavior Management Conference in 2002, and was named San Diego's "Recycler of the Year" in 2004. In 2006 the society established a new foundation for its key fundraising efforts. The following year the society adopted a new strategic plan, which included new master plans for the Zoo and Wild Animal Park. In 2008 the society found a need to rethink its

Rebranding

Beginning in its 93rd year, the Zoological Society of San Diego underwent a

, with all branches of the organization being renamed with the exception of the San Diego Zoo, and all receiving new logos. In June 2010 the society's board of trustees approved rebranding the rest of the organization's facilities. The San Diego Zoo Wild Animal Park became the San Diego Zoo Safari Park: "This allows us to more easily communicate the differences between the Zoo and the Safari Park", said Debra Erickson, Director of Communications and Interpretation for the society. "People outside of San Diego County didn't understand what a Wild Animal Park was and why, if they visited the world-famous San Diego Zoo, they needed to visit the Wild Animal Park. 'Safari Park' says it all: You go to the Safari Park to take one of a variety of

s." The Zoological Society of San Diego was renamed San Diego Zoo Global, the umbrella title for the entire organization: "Individuals had an impossible time remembering the corporate name of the organization", said Erickson. San Diego Zoo Global' connotes that we are a zoo that works around the world." Summary of the rebranding name changes: *Zoological Society of San Diego → San Diego Zoo Global *San Diego Zoo → San Diego Zoo (no change) *San Diego Zoo Wild Animal Park → San Diego Zoo Safari Park The rebranding also created a new program, the San Diego Zoo Global Wildlife Conservancy, intended to unify and raise the profile of the conservation efforts pursued by the Zoo, Safari Park, and the conservation science department. According to Erickson, the Conservancy "helps us communicate that we are more than a zoo; we are a wildlife conservation organization." One of the Conservancy's first initiatives was a partnership with Nature and Culture International, begun in 2011, to assume operation of the

In 2010, San Diego Zoo Global hosted a conference of world experts to discuss "The Future of Zoos". For 2011 the organization reported its number of card-carrying members at 530,740, and combined attendance for the Zoo and Safari Park at nearly 5 million. In 2012 the organization partnered with the

The San Diego Zoo Academy, an internet-based training program for animal care staff worldwide, was launched that year.

2020s

In March 2021 the organization changed its name from San Diego Zoo Global to the San Diego Zoo Wildlife Alliance. Former CEO Paul Baribault said the new name better reflects the nonprofit group's focus on conservation and the interconnectedness of animal and human health. While it is best known for its two conservation parks, the organization also supports wildlife conservation and research projects around the world. The rebrand coincided with a new visual identity that incorporated three animals that represent the San Diego Zoo Wildlife Alliance century-long conservation efforts: the lion, the California condor and the white rhino.

. The organization is funded through grants, membership revenue, and from sales of tickets, merchandise, and food at the Zoo and Safari Park. Additionally, the San Diego Zoo Wildlife Alliance receives revenues from property taxes collected by the City of San Diego, the result of a proposition passed in 1934 that allows the organization to receive $0.02 from every $100 collected in property taxes, to be used for maintenance of zoological exhibits at the San Diego Zoo. By 2015 this amounted to approximately $12 million a year, out of the organization's total annual earnings of almost $270 million. The largest grant in the organization's history came in 2000: $7.5 million from the Arnold and Mabel Beckman Foundation, which went toward the construction of the Arnold and Mabel Beckman Center for Conservation Research on the Wild Animal Park property. The largest individual donation to the organization came in 2004: $10 million from the estate of

, the organization created the Gold Conservation Medal as an award given to outside parties. Nine medals were awarded that year, and it has since been customary to award two each year, one to an international figure and one to a regional figure. In 1971 the society established a set of criteria for selecting recipients, declaring that the medals should be awarded to "individuals who, through research and publication, have furthered knowledge of the habits and habitats of wildlife, ..who have been active in the preservation of endangered and other species of animals through breeding programs, research, and the establishment of game and wildlife preserves, .. andwho have furthered the cause of conservation through continued financial support and through their influence and publicity." In 2008 the Conservation Award was expanded to include four categories: Lifetime Achievement, Conservation in Action, Conservation Advocate, and Young Conservationist. Several Conservation Medals have been awarded posthumously. Recipients include:
