Number of red-listed ecosystem types
In the past 50 years no ecosystem types have Collapsed CO on mainland Norway, Svalbard, or in the surrounding coastal areas and ocean. However, 8 ecosystem types are Critically Endangered CR, 23 are Endangered EN, 43 Vulnerable VU and 38 are Near Threatened NT. In addition, 11 ecosystem types are categorised as Data Deficient DD.
Of the 258 assessed ecosystem types, 48 % are red-listed.
Mainland Norway and marine areas
For mainland Norway and marine areas, 106 ecosystem types are on the Red List, and 105 ecosystem types are assessed as Least Concern LC. This means that half of the 211 assessed ecosystem types are red-listed. Of the ecosystem types on the Red List, 66 are assessed as being threatened on the mainland – these comprise 31 % of the assessed ecosystem types.
Three ecosystem types on the mainland are Critically Endangered CR – Semi-natural grassland, Earth pyramid and Semi-natural fen. 22 are Endangered EN, and 40 ecosystem types are Vulnerable VU.
In total, 34 ecosystem types are assessed as being Near Threatened NT. Near Threatened includes ecosystem types that are almost assessed as threatened.
Ecosystem types are placed in the category Data Deficient DD when there is inadequate information to make an assessment, and possible categories range from Critically Endangered to Least Concern. Six ecosystem types on the mainland have been categorised as Data Deficient.
On Svalbard, 47 ecosystem types have been assessed. Of these, 17 ecosystem types (36 %) are on the Red List, and 30 ecosystem types (64 %) are assessed as Least Concern. Nine ecosystem types are assessed as threatened, comprising 16 % of the assessed ecosystem types on Svalbard.
Four ecosystem types on Svalbard are Critically Endangered – these are Arctic steppe, Thermal spring, Lime-rich (permafrost) fen margin, and Polar sea-ice.
The habitat type Fjord waterbody is Endangered on Svalbard. Ice scoured littoral rock, Ice scoured boulders and Brackish hydrolittoral sand are all Vulnerable.
