The site comprises all of the islands (and surrounding waters) in this offshore archipelago. Traditional harvesting of seabirds takes place (`Other' land-use): the eggs of Fulmarus glacialis and auks; the young, mainly of Sula bassana; and adults of Fratercula arctica.
More than one million pairs of seabirds breed here, including the largest congregation of breeding Oceanodroma leucorhoa in Europe, more than 90% of breeding Hydrobates pelagicus in Iceland, and 100% of breeding Puffinus puffinus in Iceland.
