To keep lion populations healthy and thriving and to avoid conflicts with local communities, wildlife management is necessary. In Kenya, this is the responsibility of the Kenya Wildlife Service (KWS). Together with scientists from Leiden University and the Wildlife Research and Training Institute in Kenya, KWS is now mapping the genetic diversity of their lion populations. The aim is to assess the impact of management interventions on lion diversity to date and to devise more effective ways to conserve lions in the future.
