Résumé
Gabon, one of the countries of the Congo Basin, is more than 85% covered by forests that host large biodiversity, including a diverse array of large mammals. This biodiversity can be threatened by forest logging activities, and by invasive alien species – the second greatest cause of biodiversity loss after habitat destruction. The issue of invasive alien species in Gabon is less documented; however, the consequences of these harmful exotic species are visible, such as Wasmannia auropunctata, which already impacts local biodiversity.
