Bern Convention Group of Experts on Invasive Alien Species
The Bern Convention created in 1992 a specialised group of experts called "Group of Experts on Invasive Alien Species". The group collected and analysed different national laws dealing with invasive species and proposed work aimed at the harmonisation of national regulations on introduced species, particularly on the fields of definitions, territorial scope of regulation, listing of species whose introduction is undesirable, identification of authorities responsible for permits, conditions for issuing such permits and control involved.
