Our policy forum aimed to highlight several challenges to implementing a pan-European Invasive Species Strategy, one of which is how best to prioritize invasive species for blacklisting. Among many potential criteria used to blacklist species (7), we would argue against making an allowance for species conservation status in the native territory or the potential economic value in the introduced region. If a species is perceived as a pest where introduced, it will often be blacklisted, regardless of its conservation status in its native range. Two of our examples of native European species that are invasive elsewhere in Europe are either Red Listed (2) or classified as nationally threatened (3), but this has not stemmed eradication attempts in the places where they are considered invasive.
