Etude pédologique et phytosociologique de deux mares dans le Parc National du Niokolo Koba dans un contexte d’invasion biologique par Mimosa pigra

A soil and phytosociological study of two ponds, Nianaka and Dalafourounté, in Niokolo-Koba National Park reveals that the invasive species Mimosa pigra thrives on heavy clay soils with adequate mineral nutrition. The research finds that while Mimosa pigra is exclusively invasive at Nianaka, its presence varies around Dalafourounté. The flora analysis shows a higher diversity of dicotyledons (91.4%) compared to monocotyledons (8.6%) at Dalafourounté, with both ponds dominated by Combretaceae and Mimosaceae families. The study suggests that the relief and water levels of the ponds may contribute to the invasive behavior of Mimosa pigra. This research provides insights into the ecological factors influencing biological invasions in UNESCO World Heritage Sites.
