of 15 moss species (three peat mosses and 12 brown mosses) were determined, as well as 23 species of vas-cular plants.

The analysed microhabitats represented four vegeta-tion types, exhibiting zonal distribution, ranging from the floating mat to peatland with dominating Sphagnum.

The following were analysed: (I) floating vegetation mat and Iow hummocks with rush vegetation, (II) rich fen, (III) Sphagnum lawns and (IV) a smali hummock of Sphagnum. Species composition and quantitative ratios of vegetation in peatlands microhabitats are presented inTable 1.
