Membership Zoo Society membership offers free admission to John Ball Zoo and more than 100 other zoos and aquariums. Members receive the Zoo News publication which updates them on events and programs at the Zoo. Members also receive discounts in the gift shops and on classes and programs. An annual members' picnic is held after hours each September and special previews are planned for members when the Zoo opens new exhibits. The funds from this program go to support the John Ball Zoo Society Wildlife Conservation Fund.
Funds help support research in captive wildlife management, education, and field projects.
Sponsors receive a thank-you letter, sponsorship certificate, an information sheet on their animal, and participants are recognized annually on the Keeper of the Wild plaque in the children's zoo. The fund annually distributes small grant awards to wildlife conservation field projects, education programs and captive animal management studies. The fund has helped establish wildlife reserves in Indonesia, Tanzania, and Costa Rica. It has funded education programs in Central and South America. Grant applications are due annually April 1.
