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.
