Norwegian blacklist

The Norwegian blacklist ("Norsk svarteliste") is an overview of alien species in Norway, whith ecologial risk assessments for some of the species. "Norsk svarteliste" was first published in 2007 by the Artsdatabanken (species databank) and developed in cooperation with 18 scientific experts from six research institutions.

"Norsk svarteliste 2007" is the first issue, and is compiled as a counterpart to the Norwegian redlist of 2006.

Norsk svarteliste 2007

"Norsk svarteliste 2007" contains a total of 2483 species of plants, animals and other organisms, 217 of which are risk assessed. A set of criteria has been developed to ensure a standarised assessment of the ecological consequences of alien species.

The assessed species are placed in categories according to the risk they represent.

* High risk - 93 species
* Unknown risk - 83 species
* Low risk - 41 species

Alien species on Svalbard, Bjørnøya and Jan Mayen are not assessed.

Result

Among the 93 species which are found to threaten the natural local biological diversity, are bacteria, macroalgae, microalgae, pseudofungi, fungi, mosses, vascular plants, comb jellies, flatworms, roundworms, crustaceans, arachnids, insects, snails, bivalves, tunicates, fishes and mammals.

Among the vascular plants with a high risk, are "Heracleum tromsoensis", "Acer pseudoplatanus" and "Lupinus polyphyllus". Among the flatworms; "Gyrodactylus salaris", among the crustaceans king crab and american lobster. Five species of mammals are noted as high risk species; West European Hedgehog, European Rabbit, Southern Vole, American Mink and Raccoon.

National redlist

The National redlist is an overview of plant and animal species which are threatened by extinction, subject to significant reduction, or are naturally rare.
