Main research findings

Swayne’s hartebeest (Alcelaphus buselaphus swaynei) is an endemic and endangered herbivore recently confined into two protected areas: Senkele Swayne’s Hartebeest Sanctuary and Maze National Park, in Ethiopia. This study aimed to investigate the current conservation status and behavioural ecology of the Swayne’s hartebeest using multiple approaches. We estimated their total population at 1,528 individuals and livestock share their geographic range. Genetic parameters suggest weak sub-structuring between the two populations. Swayne’s hartebeest exclusively preferred grassland where controlled burning played an important role in maintaining habitat quality. The dynamic nature of resource availability in different seasons explains the variation in activity patterns and space use of the Swayne’s hartebeest over time, but their home range size is less influenced by seasonality. Senkele Swayne’s Hartebeest Sanctuary is of critical conservation value to the Swayne’s hartebeest; however, the surrounding communities endure significant human-wildlife conflict and hence the survival of this relict population of Swayne’s hartebeest in the sanctuary remains at risk. In conclusion, as per the IUCN guideline for threatened species, the Swayne’s hartebeest populations need urgent conservation measures to ensure its sustainability. Our findings will help to inform management strategies and conserve the last two extant populations of Swayne’s hartebeests.
