Spruce forests (Ass. Sphango girgensohnii - Piceetum (Br.-Bl. 39) Polak. 62) on excessively moistened peatlands in Latvia
Priedits, Normunds
The research carried out on swamp spruce forests on peatland in Latvia gives a detailed notion of the phytosociological structure of Ass. Sphagno girgensohnii - Piceetum (Br. - BI. 39) Polak. 62 in the western part of the East-European Plain at the Baltic Sea. The paper reflects one of the aspects of swamp forest investigation results in Latvia on forest communities, its biodiversity and presevation. Ninety-one sample plots with Picea abies as the dominant in the tree layer or co-dominant with Betula pendula, Betula pubescens or Pinus sylvestris are described according to phytosociological Braun-Blanquet methodology. Floristic features of spruce communities belonging to Caricoso-phragmitosa and Dryopterioso-cnricosa forest site types are analysed. The results are compared with similar investigations carried out in the Baltic Sea region states and neighbouring countries.
