Trait groups of alien plants and their abundance in the Netherlands

Research output: Chapter in Book/Report/Conference proceedingAbstract

Abstract

Invasive plant species can have major effects on the biodiversity and ecosystem functioning. Preventing their introduction would be the most cost-efficient solution. The majority of alien plants are introduced intentionally, for example by ornamental plant trade. If we knew which of these plants are likely to become noxious invaders, their introduction can be easily prohibited. Many studies addressed plant traits that predict invasiveness. Finding one trait or a group of traits that predict invasiveness among all plant species is unrealistic. But, at the level of genera or ecosystems, success has been achieved. Therefore, when examining the patterns among invasive plant species in the Netherlands we followed a multi-trait-group approach, linked to the species habitats. We aim to identify groups with a high and a low invasion potential. An advantage of doing this study in the Netherlands is the availability of extensive information on plant presences and abundances at the national and local scales. Defining which species are invasive and which are not is a difficult aspect of invasion ecology, many different definitions have been used. The Dutch databases are very helpful in this. Instead of using expert judgement for defining invasive and non-invasive alien species, we use local and national plant abundances to indicate the impact on the communities
