Abstract
All Swedish forest land is at present being surveyed with the aim of mapping woodland key habitats which have an estimated number of ca. 70 000. An untested requirement of these habitats is that they should contain red-listed species. In order to investigate if they fulfill their aim, an inventory of nationally red-listed bryophytes and lichens was performed in ca. 120 randomly selected woodland key habitats distributed throughout the country. The species were recorded in line transects, covering the whole surface of the habitats. The mean number of red-listed species per habitat was 0.7 for bryophytes and 1.4 for lichens with 11 species at the richest site and 71% of the sites having at least one species. Nemoral forests and coniferous forests were the most species-rich habitat types. The habitats of northern Sweden were more species rich than the southern ones. There were weak correlations between presence of bryophytes and lichens. The study shows that a majority of the woodland key habitats contain red-listed bryophyte and lichen species. Further studies are needed in order to record more organism groups and to compare the woodland key habitats with the surrounding matrix forests.
