One third of the zoo's 130 species are cared for within Species Survival Plans, a global initiative to protect at-risk genetic diversity. Twenty-nine species at the zoo are in danger of extinction. Other species are considered "ambassadors" for endangered species. The Calgary Zoo uses a team of educators including animal keepers, interpreters, teachers, and volunteers to increase awareness among visitors about the beauty of nature and threats to wildlife. Each year the zoo's formal programs connect directly with more than 575,000 adults and children.
