During August and September AquaBiota has performed an extensive survey of reefs and large shallow inlets and bays along the Swedish Baltic coast. The aim has been to verify and follow up status for the habitats within the Natura 2000 system. 600 stations has been investigated, with start in Västerbotten and finish in Skåne by the Öresund bridge. Right now all films are being analysed and data will be delivered to the Swedish data host SMHI in December at latest. The survey is a part of the programme Biogeografisk uppföljning (Eng: Biogeographic follow-up), which is headed by the Swedish Species Information Centre.
