Acknowledgements

Lions are an iconic species, both loved and feared. While they do not have the striking color patterns of a jaguar or the cultural significance of a tiger, the striking mane and complex social structure makes them unique among all the wild cats. Nearly half of all AZA-accredited institutions house lions, a testament to their charisma and popularity. For many years lions were easy to breed and we believed they would always be in zoos. Over those same years we saw tens of thousands of them in Africa and believed they would rule the wild forever. In the thirty years since the AZA Lion SSP was established we have been proven wrong on every level.

Every day keepers, animal managers, wildlife managers, and scientists work tirelessly to ensure that lions remain the highlight of a zoo experience or a wildlife safari. Mike Fouraker, Tarren Wagener, and Bob Wiese managed this SSP many years before I did and much of the information in this document comes from their hard work, as well as the advisors and active members of the SSP, and they deserve recognition for their many years of voluntary service to the AZA Lion SSP.

The AZA Felid TAG is made up of an incredible group of individuals whom I am grateful to call mentors, colleagues, and friends. I owe special thanks to Norah Fletchall and Danny Morris for inviting me into this group and providing me opportunities and support over the last seven years.

This document has been a long time coming, for a variety of reasons. It represents the best information available today from the best zoos and most experienced animal managers in AZA and around the world. It is a living document and should be continually updated with both the published and anecdotal information available at the time. The intent of this document is to serve as a resource for the keepers, managers, and curators that care for this species today or hope to in the future, so that we can provide the best possible care for every lion and ensure that future generations hear a lion's roar both at their zoo and in the wild.

Preamble

AZA accreditation standards, relevant to the topics discussed in this manual, are highlighted in boxes such as this throughout the document (Appendix A).

AZA accreditation standards are continuously being raised or added. Staff from AZA-accredited institutions are required to know and comply with all AZA accreditation standards, including those most recently listed on the AZA website () which might not be included in this manual.

Taxonomic Classification

Taxonomy

Animalia Chordata Mammalia Carnivora Feliformia Felidae

Genus, Species, and Status

Dubach et al. (2005) recognize two subspecies, the Asian Lion (P. leo persica) and the African Lion (P. leo leo). In their review in Mammalian Species, Hass et al. (2005) listed seven extant subspecies, although none of these have been subjected to molecular analysis. Haas et al.'s classification is listed in Table 2 below. The AZA Lion SSP manages all African lions as P. l. leo, following Dubach et al.'s classification.

AZA Status SSP

IUCN data current as of 2008 indicates that African lion populations have declined as much as 30% over the last two decades (). Lions have disappeared from over 80% of their historic range, and current numbers indicate there may be less than 30,000 wild lions left in Africa. They remain in 26 countries in Africa but only 7 of these (Botswana, Ethiopia, Kenya, South Africa, Tanzania, Zambia and Zimbabwe) boast populations over 1000 ().

For many years, African lions were not a priority for conservation but in the last 2 decades, they have come under threat from a variety of factors, including habitat loss, human conflict, and disease from domestic animals. Retaliatory killing in east Africa and distemper and bovine tuberculosis outbreaks in southern Africa threaten the last large populations of lions on the planet.

The AZA Lion SSP began as a program for Asiatic lions 1981 and the focus on African lions did not begin until the early 1990s after genetic testing revealed that animals thought to be P. l. persica were in fact African-Asiatic hybrids (O'Brien, et al., 1987). Efforts continued to develop an Asiatic program but a source of founders was never established. Currently the European Breeding Program (EEP), the European counterpart to the SSP, manages Asiatic lions. In 1993 the AZA Lion SSP expanded to include African lions and animals of known ancestry began to be imported from southern Africa. A moratorium on the breeding of "generic" (unknown pedigree) lions also began at this time (Fouraker, Wagener, & Wiese, 1998).
