Study of primary and secondary succession on wooded peat- bogs are presented. Research has been done on a complex of mountain peat-bogs in the Bohemian Moravian Highland (Czechoslovakia). Natural succession series began with reed sedge and reed stands and terminated with Viccinio uliginosi-Pinetum, Calamagrostio villosae-Piceatum and Alnion glutinosae uder oligotrophic, oligo-mesotrophic and meso-eutrophic conditions, respectively. In marginal parts of peat-bogs (lagg) sedge fens are followed by birch cart. Open pine stands (Pino rotundatae-Sphagnetum) is submitted to cyclic succesion. The secondary succession may begin with the Sphagnum cuspidatum, Eriophorum angustifolium or Carex rostrata, and Carex rostrata stages, depending on trophic conditions of water. The final stage is usually Vaccinio uliginosi-Pinetum or Pino rotundatae-Spagnetum. Secondary succession pattern is influenced both by eutrophication and peat-land drainage. |
