Started in 1981, the Species Survival Plan (SSP) is population management and
conservation program for selected species of wildlife. The program's goal is to
maintain captive populations that are both genetically diverse and
demographically stable. This is achieved, in part, through the operation of
studbooks, which contain vital records of a species entire captive population.
The SSP, which is run by the American Zoo and Aquarium Association, also
participates in research, education, and programs to reintroduce some species
into the wild. Most of the SSP's 125 species are endangered or threatened. For
more information on many of the SSP's animals, visit their listing of
selected wildlife species.
