Southern three-banded armadillos were first documented in North American zoos in small numbers in 1969 and zoo breeding began that same year.
Since that time, the North American southern three-banded armadillo population has grown at a moderate rate until 1998, when the population experienced a rapid growth phase, partly due to imports. The general trend for the last 20 years has been one of positive growth (mean growth of 6%), due primarily to zoo births with periodic imports. In the past five years, population growth has averaged 3.5%.
The current SSP population of Southern three-banded armadillos consists of 150 animals (78 males and 72 females) distributed among 60 AZA and 1 non-AZA institution. The target population size for this species was set at 170 individuals by the PAX TAG in its 2009 Regional Collection Plan. Gene diversity 100 years from present is projected to be 87%. Under AZA Sustainability Guidelines the population is currently managed as a Yellow SSP Program.
Southern three-banded armadillos are found across much of South America. The species is currently listed as Not Threatened by IUCN.
