Beschreibungen/Notizen

• The authors propose here a list for the province of Quebec constructed using an innovative approach based on well-defined criteria, consideration of all potential problems associated with exotic plants, use of credible scientific data, assessment by a panel composed of experts with diverse expertise and who are also potential users of the list, use of a decision support approach, and a debate among experts in order to reach a verdict concerning the status of each candidate plant. The list contains 87 of the 908 taxa of exotic vascular plants that are naturalized in Quebec, i.e., 9.6% of the total. Evaluating the threat posed to biodiversity by individual species was a challenge, because few relevant studies have been published. The resulting list is not definitive, and should be used with caution. However, they estimate that the approach is more rigorous than the other qualitative approaches developed to date, with performance that matches the semi-quantitative or quantitative tools frequently used for assessing invasive plants, such as the Australian Weed Risk Assessment.
