Abstract

Four peatlands areas were investigated in this thesis, i.e. Lommaflet and Gatmyren are typical mires for the south-eastern Sweden, while the Linkowo and Sarbinowo mires are characteristic for the north-western Poland. The comparison was carried out on several levels: vascular plant flora, cryptogamic plant flora, plant communities, red-listed species, species and plant communities valuable at the European scale, origin of peat deposit, type of peatland, changes in the mire limits and the watershed area in the last 50 years. Factors related to changes in wetland structure and composition in time and space were identified. Peatlands classified during the field work fulfilled the following assumptions: the peatlands are of a topogenic type, the area contains from 9.66 to 34.3 ha, the mires were formed during the terrestrialisation process, and the water flushing down from the surrounding terrain is its main source. The investigated mires were formed since the end of the last glacial period. The glaciation process was completed about 9-13 years ago on the terrain of the studied areas. The Linkowo and Sarbinowo peatlands started to develop about 4 thousand years earlier than the Lommaflyet and Gatmyren ones. The peatlands are situated in the area covered by forests and characterised by high intensity of silvicultural treatments within the watershed area. During the field work carried out on four mires, 32 species of mosses, 142 vascular plant species and 23 plant communities were investigated. The origin of the Lommeflyet and Gatmyren mires is connected with a shallow water reservoir, while the Linkowo and Sarbinowo ones are developed on a deep lake. The investigated mires are in a period of transition from topogenous into ombrogenous type. The main changes within the mire limits in the last 50 years are as follows: drainage process, increased area of Vaccinio uliginosi–Pinetum Kleist 1930 em W. Mat. 1962 plant community and decreased area of open bog habitats. Clear cuts are the main disturbing factor stated during the last 50 years on mire watershed area. Drainage, past fire events, nitrogen deposit, changes on the watershed area are the main factors determined that induced changes in the plant cover on the peatland surface.
