This survey was conducted in two protected areas in Nigeria to genetically identify individual lions and to determine the genetic variation within and between the populations. We used faecal sample DNA, a non-invasive alternative to the risky and laborious task of taking samples directly from the animals, often preceded by catching and immobilization. Data collection in Yankari Game Reserve YGR spanned through a period of five years 2008 –2012, whereas data in Kainji Lake National Park KLNP was gathered for a period of three years 2009, 2010 and 2012. We identified a minimum of eight individuals 2 males, 3 females, 3 unknown from YGR and a minimum of ten individuals 7 males, 3 females from KLNP. The two populations were found to be genetically distinct as shown by the relatively high fixation index FST  = 0.17 with each population exhibiting signs of inbreeding YGR FIS  = 0.49, KLNP FIS  = 0.38. The genetic differentiation between the Yankari and Kainji lions is assumed to result from large spatial geographic distance and physical barriers reducing gene flow between these two remaining wild lion populations in Nigeria. To mitigate the probable inbreeding depression in the lion populations within Nigeria it might be important to transfer lions between parks or reserves or to reintroduce lions from the zoos back to the wild.
