Spatial distribution modelling of a threatened lion population in relation to prey populations in Niokolo-Koba National Park, Senegal

Abstract:The lion has experienced a major decline in its habitat and population size in recent years. This is explained by the transformation of its habitat and the reduction of its potential prey. Our study therefore focused on modelling its habitat and its prey and the analysis of its diet to contribute to its conservation in the Niokolo-Koba National Park (NKNP). Elevation, annual precipitation, NDVI, land cover type, distance from large water bodies, prey availability, poaching pressure and livestock pressure were used as variables in modelling the lion habitat with MaxEnt software. The model obtained with the modelling of the lion habitat performs well, with an AUC of 0.96, and indicates that the most favourable habitat for the lion is located in the centre of the park. This distribution is influenced by elevation, annual rainfall, prey availability, poaching pressure and livestock pressure.
