The Helgeland archipelago stretches across 200 km, extending from Trøndelag in the south to Salten in the north. This iconic part oftheNorwegian coast comprises a myriad of islands and islets (more than 12,000) and large shallow sea areas (fig. 61 and 62). All along the coast there are white beaches, sheltered coves, fjords and steep towering mountain walls rising straight from the open sea. A wealth of marine life thrives in the area, spanning from the smallest microalgae to the largest mammals. Harbor seals (Phoca vitulina), Atlantic puffins (Fratercula arctica), white-tailed eagle (Haliaeetus albicilla) and greylag goose (Anser anser) are among typical species encountered.

This chapter provides an overview of the status and trends in biodiversity and ecosystem function through assessment of key species and habitats, and summarizes the ecological status of selected Nordic regions. Important habitats across the Nordic coastal region include sea grass beds, kelp forests, blue mussel beds and soft sediments. Declines in sea grass have occurred since the 1970's, most likely due to eutrophication and overfishing. Norwegian kelp forests are recovering following severe losses in the 1960–1970's, most likely due to increased water temperature and changes in grazing pressure. Seabird populations have declined significantly during the last decades, reaching historical lows. Knowledge gaps are identified and a common biodiversity indicator system across the Nordic region is suggested. An indigenous local knowledge perspective is also presented.
