Primary and secondary succession on wooded peat-bogs

Abstract

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 Viceinio uliginosi-Pinetun:, Calanmgrcstio villosae-Piceatum and Alnion glutinosae uder oligotrophia oligo-mesotrophicand meso-eutrophic conditions, respectively. In marginal parts of peal-bogs (lagg) sedge fens are followed by birch carr. Open pine stands (Pino rotunda(ae-Sphagneium) is submitted to cyclic succeiion. The secondary succession may begin with the Sphagnum cuspidatuni, Eriophorum angustifoliu/n or Carex rostrata, and Carex rostrata stages, depending on trophic conditions of water. The final stage is usually Vaccinio uliginosi-Pinetum or Pino rctundatae-Spagnetum. Secondary succession pattern is influenced both by eutrophication and peat-land drainage.
