Site details


Site description: The main area of interest can be divided into four island groups: Stora Nassa˜c.400 closely spaced rocky islets with little or no vegetation. The largest island has maritime Betula forest whilst others support Juniperus. Wet grasslands are also present. Lilla Nassa˜smaller area than Stora Nassa but with islands more spread out and with very little vegetation. Gillöga˜flat islands in shallow waters with abundant cover and submerged offshore reefs. Svenska Högarna˜a flat island with Juniperus, and heather Calluna. The archipelago is largely uninhabited but during the summer is a popular leisure (boating) area.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: This is a very important breeding area for seaducks, waders, gulls and seabirds.
Delineation rationale: Old area: 9100ha (typing error?) Changed due to better information on border and size. /Robert Ekblom (2007-10-22)
