168 National responsibility species constitute a significant part (20%) of the global population in Greenland, why their global survival are dependent on a favourable conservation status in Greenland. Endemic species or subspecies are also of national responsibility as the total global population is found within Greenland. Those occurring in the assessment area are listed in Table 6.3.2. Table 6.3.2. Species of national responsibility and endemic species (subspecies) occurring in the assessment area. National responsibility species Narwhal Walrus Polar bear Light-bellied brent goose Greenland white-fronted goose (endemic subspecies) Brent goose Mallard (endemic subspecies) Common eider White-tailed eagle (endemic subspecies) Iceland Gull (endemic subspecies) Black guillemot Little auk Species with isolated population in Greenland (endemics not included) Great cormorant Red-breasted merganser Harlequin duck Harbour seal Harbour porpoise Atlantic salmon (local spawning stock) The International Union of Nature Conservation (IUCN 2010)) lists the species, which are globally threatened. See Table 6.3.3 for the species occurring within the assessment area. Table 6.3.3. Species occurring in the assessment area and listed as globally threatened (IUCN 2010). Species Redlist category Ivory gull Near Threatened (NT) Polar bear Vulnerable (VU) Fin whale Endangered (EN) Blue whale Endangered (EN) Sperm whale Vulnerable (EN) Narwhal Near Threatened (NT) Beluga whale Near Threatened (NT) 6.4 NGO designated areas The international bird protection organisation BirdLife International has designated a number of Important Bird Areas (IBAs) in Greenland (Heath & Evans 2000), of which eight are located within the assessment area (Fig. 6.1.1). These areas are designated using a large set of criteria, for example, that at least 1% of a bird population should occur in the area. For further in-
formation see the IBA website (http://www.birdlife.org/ action/science/sites/index.html). Some of the IBAs are included in or protected by the national regulations for example as seabird breeding sanctuaries, but many are without protection or activity regulations. 169
