Svenska artprojektets marina inventering: slutrapport

The purpose of the marine inventory of the Swedish Taxonomy Initiative was to monitor marine invertebrates on the sea floors along the Swedish West Coast. The inventory was carried out between 2006 and 2009. 378 localities were visited and 527 samples taken. In total, 1203 species have hitherto been identified from the material, of which 30 species were new to science and 43 species new to Sweden. All observation data have been entered into Artportalen, the Swedish Species Observation System. Species were to a large extent identified already in the field. Representative samples were collected and the material is now kept and preserved at the Gothenburg Natural History Museum. Remaining unidentified specimens have been identified with the help from a large network of species experts. This report describes the purpose, design, performance and results of the inventory and gives recommendations for future inventories. Species lists, and a table of findings of redlisted species are also included, as well as accounts for findings of rare and/or interesting species from Bratten and Svabergsgrunden. The marine inventory was carried out in close cooperation with the regional conservation authorities in the area and has already resulted in protection of some of the most valuable areas covered in the inventory.
