  • Serengeti leopard population densities healthy but vary seasonally, study finds

    Stunning closeup of a leopard in a tree. The leopard is lit with an intense yellow morning or evening light. It is peering into the camera and looks relaxed.

    Leopard population densities in the Serengeti National Park in Tanzania are comparable to those in other large protected areas, researchers found. The scientists used camera-trap data from the Snapshot Serengeti project.

    The paper “Counting cats for conservation: Seasonal estimates of leopard density and drivers of distribution in the Serengeti” is available online and from the U. of I. News Bureau.

    With this study, Allen and his colleagues contributed to an international effort called Snapshot Safari that recruits scientists and citizen-scientists to use camera-trap data from sites across Africa to identify species and population trends and make their findings freely available to the public. The aim is to promote wildlife conservation in Africa.
