The ecological impact assessment scheme that has
been developed to classify alien species in Norway is presented. The underlying
set of criteria enables a generic and semi-quantitative impact assessment of alien species.
The criteria produce a classification of alien species that is testable, transparent and
easily adjustable to novel evidence or environmental change. This gives a high
scientific and political legitimacy to the end product and enables an effective
prioritization of management efforts, while at the same time paying attention to
the precautionary principle. The criteria chosen are applicable to all species
regardless of taxonomic position. This makes the assessment scheme comparable
to the Red List criteria used to classify threatened species. Full text: © 2013 Springer. The original publication is available at SpringerLink.
