BfN Schriften 490 - Analysis and prioritisation of pathways of unintentional introduction and spread of invasive alien species in Germany in accordance with Regulation (EU) No 1143/2014
In our study, the method applied for the prioritisation of pathways and the results obtained for Germany are presented and discussed.
For the purpose of the prioritisation presented here the pathways have been split into three invasion stages (introduction, escape or release, and spread incl. establishment)
Introduction pathways: describe routes and mechanisms through which an alien species reaches the reference area
Escape or release pathways: describe routes and mechanisms through which an alien species enters the natural environment (not under human care)
Spread pathways: describe routes and mechanisms that lead to extensions and/or shifts of an alien species’ area of distribution.
