Other Site Characteristics

Ertholmene er Danmarks østligste øgruppe 17 km nordøst for Bornholm. Omfatter de beboede øer Christiansø og Frederiksø, den ubeboede ø Græsholm samt et antal skær. Græsholmen er den næststørste af øerne. På dens flade midterparti er klippegrunden græsdækket og dybt vand omgiver øen. De mange fugle på øen har bevirket, at vegetationen på Græsholmen er delvis afsvedet. Det er forårsaget af fuglenes gødning (guano). Revet udgør den naturlige fortsættelse af klippeøen Ertholmene og indeholder således alle marine zoner fra kysten og nedad. Christiansø og Frederiksø har stor kulturhistorisk og rekreativ værdi og har spredte krat i klippeterrænnet, samt mange naturtyper i forhold til øernes lille areal.

4.2 Quality and importance

H: Rundt om øerne findes væsentlige revformationer og på øerne klipper, søer og strandengsvegetation. Specielt fuglelivet er velbeskrevet på øen og det omgivende hav, ligesom der findes en speciel flora med flere østlige og tørke/varme-elskende plante-arter. Der er derimod ikke specifikke undersøgelser af havets bundflora og -fauna i området. Området er den østligste forekomst af naturtypen rev i danske farvande. EF: Området er ikke af stor vigtighed som fugleområde internationalt, dog forekommer de fleste år betydelige rastpopulationer af bilag I arterne Blåhals (Luscinia svecica) og Rødrygget Tornskade (Lanius collurio). På nationalt dansk plan er området enestående med de eneste kolonier i landet af Alk (Alca torda) og Lomvie (Uria aalge) og landets næststørste koloni af Ederfugl (Somateria mollissima).
