Drawa Forest is a big forest complex, ca 2000 km2, in north-western Poland, located on the big post-glacial outwash plain. For preserving outstanding natural values, in the centre of the forest complex, Drawa National Park was established in 1990 y. The whole central part of the complex, ca 740 km2, was designated as Natura 2000 site Uroczyska Puszczy Drawskiej PLH320046. Although the peatbogs occupy no more than 2% of the Natura 2000 site, and are generally small (0,5-100 ha), they are crucial for natural values. Natural habitats 7110, 7140, 7230, 91D0, 3160 and 3140 are protected here (pp. 26-35). Chamaedaphne calyculata, Eriophorum gracile, Liparis loeselii, Hammarbia paludosa are the rarest plats related to peatbogs and fens of the region. Carex limosa, Scheuchzeria palsutris, Epipactis palustris, Dactylorhiza incarnata, D. majalis, D. maculata, Drosera rotundifolia, D. anglica, D. intermedia, Utricularia vulgaris, U. australis, U. minor, U. intermedia, Cladium mariscus have viable populations.Vaccinium uliginosum and Empetrum nigrum are locally rare. There are 26 Sphagnum species in the local bryoflora, most of the number of 36 species growing in Poland. There are numerous localities of Paludella squarrosa, Helodium blandowii, Tomentypnum nitens, and some localities of Drepanocladus verniculosus and Scorpidium scorpioides. Description of 53 representative bogs and fens are presented in this publication. The peatbogs in Drawa Forests are located in various topographic situations: from kettle bogs, through bogs filling post-glacial channels, bogs is small depressions, bogs in bigger depressions, bogs and fens in lakes ends or bays, “pocket bogs” (adjacent to lakes but normally isolated by mineral barriers), to the fens developed from former lakes in post-glacial valleys, commonly adjacent to contemporary rivers. The history of the peatbogs is recorded in their stratygraphy. The general pattern typical for the region is: succession from the lake (documented by gyttja deposits), through sedge fens, and brown ...
