Abstract

The EPPO Decision Support Scheme for Pest Risk Analysis was fundamentally revised by the EU project PRATIQUE. Based on the examples of Polygonum perfoliatum (mile-a-minute-weed) and Eichhornia crassipes (water hyacinth), its applicability for invasive alien plants was tested. Results and changes compared to the previous scheme are presented in this paper. Among other things, rating guidance, defined assessment scales and computer assisted tools increased user friendliness and consistency in the risk analysis process. For the two plants tested here, documented invasion history as well as biotic and abiotic requirements show that they can establish and spread in Europe and cause damage.
