Draft for Institutional Representative Review – Please Respond by 3 March 2017 Population Analysis & Breeding and Transfer Plan Cheetah (Acinonyx jubatus) AZA Species Survival Plan® Yellow Program AZA Species Survival Plan® Coordinator Adrienne Crosier, PhD, Smithsonian’s Conservation Biology Institute – Center for Species Survival, ([email protected]) & AZA Studbook Keeper Erin Moloney, Busch Gardens, ([email protected]) AZA Population Advisor John Andrews, Population Management Center ([email protected]) 1 February 2017 Draft for Institutional Representative Review – Please Respond by 3 March 2017 Executive Summary 2017 Species Survival Plan® for the Cheetah (Acinonyx jubatus) The Cheetah SSP population currently consists of 315 cats (151 males, 164 females) at 59 facilities (55 AZA, 4 non- AZA) as of 18 January 2017. Currently, there are thirteen cheetahs (9.4) held at non-AZA facilities. The target population size set by the Felid Taxon Advisory Group is 300 in the 2009 Regional Collection Plan. The population currently qualifies as a Yellow SSP Program. Current gene diversity for the managed population is 97.27% and is equivalent to the genetic diversity of a population descended from approximately 18 founders (FGE = 18.34). The standard genetic goal for AZA managed populations is to maintain 90% gene diversity for 100 years. When gene diversity falls below 90% (and average inbreeding increases), it is expected that reproduction will be increasingly compromised by, among other factors, lower birth weights, smaller litter sizes, and greater neonatal mortality. Under potential conditions, with a growth rate of 0% (lambda = 1.00), gene diversity can be maintained at or above 90% gene diversity for at least 50 years. Increasing population growth rate, representation of underrepresented founder lineages, and the proportion of breeders in the population will promote increased gene retention.

Assuming an average litter size of 3 and probability of success at 20%, this would require approximately 60 - 63 females in breeding situations. Nineteen (19) females eligible for breeding were given specific breeding recommendations and an additional 56 females have possible breeding options listed in “MateRx” tables but many of these may be less likely to breed in the next year (e.g., due to having a litter recently or due to marginal age). Recent population viability analyses indicate that the SSP can currently support providing only four cubs to education programs per year. Pulling animals from the breeding population for use in education programs will be decided on a case by case basis and after consideration of the total SSP population’s annual breeding success and overall demographic needs. Breeding recommendations are based on mean kinship, avoidance of inbreeding, avoidance of linking rare and common lineages, and behavioral and logistical constraints identified by the participating institutions. Individuals with Cheetah (Acinonyx jubatus) Species Survival Plan® - 2017 - DRAFT 1 This Program is currently a Yellow SSP and recommendations proposed are non-binding – Participation is voluntary. Dispositions to non-AZA institutions should comply with each institution's acquisition/disposition policy. Draft for Institutional Representative Review – Please Respond by 3 March 2017 low mean kinship values were prioritized and pairings with inbreeding levels higher than the current average mean kinship have been avoided. Due to the age and low likelihood of success of many genetically valuable individuals, some over-represented animals have been recommended for breeding to meet the demographic goals of maintaining or growing the population. Summary Actions: The SSP recommends 16 females to breed with specific mates and provided an additional 56 females with “MateRx” breeding options. Recommend 25 transfers to create new breeding pairs or meet institutional requests. Note, several transfers recommended in the October meeting have been fulfilled already prior to the draft distribution. No imports from or exports to other regions are recommended at this time. New education program animals will be discussed on a case by case basis and after consideration of the demographic needs of the total SSP population.
