Prolifération de Cissus quadrangularis L. dans le Parc National des Iles-de-la-Madeleine, Sénégal

National parks are representative protected areas of natural ecosystems of a country. The introduction of alien plants in natural systems present a risk to biodiversity conservation, particularly where protected areas are islands. In the past few years , Cissus quadrangularis, a plant species from I...
