Nordre Rønner. 02/09/77; Region Norjylland; 2,993 ha; 57°22N 010°56E. Natura 2000 (SPA, SAC). Sea area with stony banks and inhabited islands which support a diverse algal flora and submarine landscapes of carbonate-cemented rocks (bubbling reefs). The site is important for wintering and staging various species of waterbirds. It is also a nationally important breeding area for the Artic Tern (Sterna paradisea), and the Pipit Anthus spinoletta has its second largest breeding concentration in Denmark within the site. Breeding mammals include seal Phoca vitulina. Human activities include boat trips, seal watching tours, and local eel fishery. The island is gradually overgrown with bushes and grasses which are changing the conditions for breeding birds. Potential threats are illegal landings and disturbance of breeding waterbirds and seals, and the anchoring of boats and eutrophication are causing negative impacts on the reefs. Ramsar site no. 148.
