Prioritized lists of invasive alien plants for Franche-Comté (France)
In France, the “Conservatoire Botanique de Franche-Comté” (a Department in Eastern France) has elaborated priority lists of invasive alien plants. These lists are based on 3 criteria, assessed according to expert judgement:
- impacts on biodiversity, human health and economy (with scores ranking from 1 to 4 “+”).
- potential invasiveness of the species in Franche-Comté according to its behaviour elsewhere in the country
- the current distribution of the species in Franche-Comté.
The lists are as follows and the species have been checked against the Global Compendium of Weeds.
List 1: the 5 species listed below have major potential impacts. Their distribution remains limited in Franche-Comté, the invasion of these species might be controlled.
