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

Abstract

Dalafourounté while 24 species within 20 genera divided into 13 families have been identified at Nianaka. The proportion of dicotyledons is lower at Nianaka (83.3%) than at Dalafourounté (91.4%) and the opposite is noticed with monocotyledons, 16.7% against 8.6%. Besides, there is a dominance of Combretaceae and Mimosaceae in the flora of both ponds. In addition, Mimosa pigra is only invasive at Nianaka where it is permanently present at the edge and inside the pond while its presence around it is not constant. As a final result of this study, the Mimosa pigra invasion could be originating from the relief and the pond filling up. © 2015 International Formulae Group. All rights reserved.
