sheltered areas, typical of sheltered and semi-sheltered archipelago<br />
areas. These sheltered, relatively pristine areas are rare in the Stockholm<br />
archipelago.<br />
• Ecological functions – The bladderwrack communities around the<br />
skerries are important habitats and feeding grounds for crusteceans,<br />
gastropods and fish. Shallow areas are important to many fishes as<br />
spawning grounds and nurseries. The area is likely to be an important<br />
feeding ground for young cod and large herring (Clupea harengus).<br />
• Presence of prioritized habitats – The bladderwrack communities<br />
were extensive and shallow mixed bottoms with vegetation occur in the<br />
<strong>Gillöga</strong> archipelago.<br />
On the whole, the investigated area in the BSPA Stora <strong>Nassa</strong> – Svenska<br />
Högarna had a high habitat value. The area is pristine and situated in the<br />
outer archipelago with floral and faunal benthic communities mirroring both<br />
the areas character of outer archipelago, but also more sheltered areas found<br />
nearer the coast. The pristine environment and the variaton in substrate<br />
types and wave exposure, including more or less sheltered shallow areas,<br />
make the area important as habitat and feeding grounds for both fish and<br />
birds. The extensive bladderwrack communities are important habitats and<br />
feeding grounds for fish and other fauna. The macroalgal communities<br />
where species rich, and the fish and benthic fauna reflected the environment.<br />
Although the vascular plant communites were both species poor and sparse,<br />
similar communities have been observed in nearby areas.<br />
