The Association of Zoos and Aquariums (AZA) and it’s accredited members impact conservation, research, education and more through their programs. AZA tracks statistics about zoos and aquariums, through the Annual Report on Conservation and Science (ARCS) and other member surveys. Our members’ dedication to animal care, conservation, and education connects millions of visitors to nature each year and helps save species around the world.
What percentage of animals are in captivity?
There are approximately 800,000 animals in the care of AZA-accredited zoo and aquarium professionals. It is nearly impossible to quantify the number of animals in the wild, making it difficult to compare animals in human care to animals in the wild.
How many endangered animals are in zoos?
There are approximately 900 species classified by the International Union for Conservation of Nature (IUCN) as Vulnerable to Extinct in the wild at AZA member facilities. AZA members are working to increase wild populations of species in our care through 117reintroduction programs, including more than 50 reintroduction programs for species listed as threatened or endangered under the Endangered Species Act at AZA-accredited zoos and aquariums.
How many different species of animals are in an average zoo?
There are approximately 8,700 species of animals across all AZA-accredited zoos and aquariums and AZA Certified Related facilities. The average medium-sized zoo has about 168 different species and the average medium-sized aquarium has about 394 different species.
How many endangered species have been saved by zoos?
AZA-accredited zoos and aquariums have collaborated on breeding and reintroduction programs that have helped save at least nine species like California condors, black-footed ferrets, Przewalski’s horse, golden lion tamarins, American red wolves, and more from the brink of extinction.
What percentage of zoos are not-for-profit?
Of the 238 AZA-accredited zoos and aquariums, 54 percent are not-for-profit.
How much money do zoos spend on animals every year?
Depending on the size of the facility and the number of animals in their care, AZA-accredited zoos and aquariums can spend between $500,000 and $20 million (or more) on animals every year. At AZA-accredited zoos and aquariums, funds aren’t just spent on animal care. Over $230 million was spent on field conservation projects in 2019 and AZA’s Conservation Grants Fund has spent $7.7 million supporting over 400 conservation projects since 1991.
What is the biggest zoo in the world?
