The Belgium Forum on Invasive Species (BFIS) promotes interdisciplinary cooperation between scientists through the facilitation of information exchange and dissemination, with the hope of developing appropriate measures to control or mitigate the impacts of invasive alien species in Belgium. The site provides fact sheets / profiles of invasive alien species in Belgium, which contain taxonomic information, distribution, time and method of introduction, preferred habitat, a measure of invasiveness, as well as impacts on native species and ecosystems. The Belgian Forum on Invasive Species gathers scientific information on presence, distribution, auto-ecology, adverse impacts and management of invasive alien species. It regularly updates a reference list of exotic species in Belgium and is responsible for the elaboration of a black list gathering species with a strong detrimental impact on biodiversity.
