The occurrence of former heathland vegetation in the coastal areas of the south-east Baltic sea,in particular Lithuania: a review

Previously published pollen diagrams from the coastal area of the south-east Baltic Sea including parts of the Polish and Lithuanian peninsulas, Mierzeja Wilana (Frische Nehrung) and Kuri Nerija (Courland Spit) respectively, document the former presence of heathland vegetation and an associated burning practice. This type of human influence can be dated back to ca. 1200 B.P. at the latest, and was maintained until the 18th century. It is suggested that this former Calluna-dominated vegetation belonged to the known west to north-west European heathland vegetation. Several dwarf shrub taxa, such as Genista spp. and Erica tetralix, normally connected to heathland vegetation, may have had a former wider distribution.
