Abstract: Background: Invasive plant species are today among the greatest threats of protected areas integrity and their fight is a challenge which requires knowledge of the potential areas of distribution. The objective of this study is to draw the spatial distribution and to determine the potential distribution area of the invasive alien species as well as the environmental variables affecting their geographic distribution in Banco national park. Materials and Methods: The principle of "Maximum Entropy" was used to draw the habitats of Chromolaena odorata (L.) RM King & H. Roxb (proven invasive species) and Hopea odorata Roxb(potential invasive species) under current and future climatic conditions (2050 horizon of RCP 8.5 scenario). These species were chosen on the one hand based on the number of occurrences and on the other hand on their significant proportions in the park. The coordinates of presence of the species were collected and combined with environmental data (bioclimatic and topographical). The distribution surface area of potentially favorable or not zones, was calculated for each species.
