The phytogeography of Denmark revisited

Abstract

Patterns of vascular plant diversity in Denmark are examined, based on the most recently published Danish Flora. The highest diversity is found on the major isles of Sjælland, Møn, Falster and Bornholm, but many rare taxa occur in Jylland. Two different cluster analyses suggest a division of Denmark into six phytogeographical regions, which only partly supports earlier, more subjective divisions of Denmark. Our results suggest that north- and northwestern Jylland and the isles of Læsø and Anholt belong to the boreo-nemoral phytogeographical region, due to their high number of northern taxa, which clearly differentiate them from the rest of Denmark, despite the lack of typical boreo-nemoral tree species, such as Pinus sylvestris.

Because the tree component of vegetation often has been changed by man, the classical division of Scandinavia based on a few woody species is inappropriate. We conclude that tree-species oriented approaches are invalid for phytogeographical classifications.

Classification, based on the whole flora, and if possible also involving environmental information, is likely to be more successful and should be addressed in future phytogeographical studies.
