According to the Dutch species register there are 2011 non-native species present in the Netherlands. Moreover, a number of non-native species that are established in climatically similar countries may be transported to and potentially colonise the Netherlands. A number of these species are invasive. To allow the effective prioritisation of preventative measures and early eradication of potentially invasive - non-native species in the Netherlands, insight is required into the species that can access the Netherlands via relevant pathways and establish here.
