International Rhino Foundation:
Gladys Porter Zoo’s Director Emeritus, Don. D. Farst, D.V.M., serves as a member of the Board of the International Rhino Foundation (IRF), whose mission is to contribute to rhino conservation by providing technical, administrative and financial services and support for programs which emphasize intensive management and scientific research both in situ (in the wild) and ex situ (in captivity) as equally important components of rhino conservation.

The IRF is a non-profit organization, dedicated to the worldwide conservation of the five living species of rhinoceros: Black, White, Indian, Javan and Sumatran.

In order to support IRF conservation programs, the Gladys Porter Zoo makes an annual financial contribution to the organization.
