Szurdoki, Erzsébet: Peat mosses of North Hungary

Kis-tó and Nagy-tó are in the Bükk Mts, near Egerbakta village at about 280 m a. s. 1. Kis-tó was a Sphagnum dominated willow swamp in the first part of 20th century. At that time the water table was high, the open communities of the central part were surrounded by willow swamp. In the end of 20th century it has dried out and most Sphagna have disappeared (ZÓLYOMI 1931, DULAI and VOJTKÓ 1991, SZURDOKI and NAG Y 2002). Nagy-tó is a real pond, surrounded by Salix cinerea and sedges, and is noted for its Lemnetea communities in the open water. Peat mosses live under the willow shrubs (DULAI and VOJTKÓ 1991). The Futyó-völgy is situated in the Tarna-vidék, a hilly area lying between the Mátra Mts and the town of Ózd. The valley is covered by beech forest developed on acidic soil (Luzulo-Fagetum) with relatively wet and cool microclimate. Numerous peat moss patches have found (BAKALÁR etal. 1975, SZURDOKI and NAGY 2002). The Csipkés-kút area is part of the Bükk Mts at about 800 m a. s. 1., with forest cover, mainly with beech; the peat mosses could live on the acidic, wet forest soil (SlROKI 1961). The well-known Mohos lakes (Kis-Mohos and Nagy-Mohos) are situated in the Putnok Hills, near Kelemér village at 296 m a. s. 1. The oval-shaped bogs are surrounded by closed oak-forests dominated by Quercus cerris and Q. petraea, which turn into a shrubby marginal zone of Salix cinerea. The bogs are belted by a lag zone and different willow communities, and in the inner part Betulo puhescenti-Sphagnetiim community has developed. In the innermost part open associations (e.g. Carici lasioearpae-Sphagnetum, Eriophoro angustifolii-Sphagnelum, Eriophoro vaginati-Sphagnelum) can also be found (MATUS et al. 2000, SZURDOKI and NAGY 2002).
