This study deals with the succession of vegetation and tree stand in 16 mesic site type Scots pine ( L.) plantations after prescribed burning in Evo, Southern Finland. The oldest tree stands studied were about 30-year-old. The growth of trees followed the height index of type. The vegetation was first mesic, dominated by grasses and herbs, turning more xeric after four years. This change was accelerated by treatment with herbicides. After the closure of tree stand, vegetation became more characteristic of forest vegetation, but pioneer species and composition disappeared slowly. The basic characters of vegetation succession could be clearly described by DCA ordination and TWINSPAN classification. The study confirmed that type has succession phases which are typical for each age phases as Cajanderâs forest site type theory has proposed. However, differences in primary and secondary site factors have their own effects on the vegetation of the succession phases.MyrtillusPinus sylvestrisMyrtillusMyrtillus
