Sándor Orbán: Analysis of some plant communities based on the bryophyte layer

- 198 communities are separable and comparable on the basis of their bryophyte layer. MEIIIOUS The sampling areas were chosen in the ULikk MLs. 1

1 my are: Mt. Nagy-Eged, Mt. Csákpilis near Felsőtárkány and 'Mt. Keselyuberc near Szarvaskő. The Ceraso-Quercetum pubescentis, Que

reo tum puboscentispetraeae, Quercetum petraeae-cerris and Carpino-Fagetum conmunities were examined in Mt. Nagy-Eged (see Table 1, Nos 5, 7, 9 and 11). Communities Pulsatillo-Festucetum rupicolae, Potentillo-Festucetum pseudodalmaticae and Quercetum petraeae-cerris were examined near Szarvaskő (see Table 1, Nos 3, 1 and 8). The Seslerio-Quercetum, Seslerio-Quersceturn caricetosum humilis, Deschampsio-Fagetum and Grimmietum orbicularis communities were investigated in Mt. Csákpilis. The nomenclature of communities follows Soó (1964). 2 Fifty sample plots of 10 x 10 cm are) were collected randomly in each of the above mentioned communities. All bryophyte species were collected which occurred in the sample plot. The 50 randomly taken plots are enough for the collection of all bryophyte species which represent the communities. The bryophytes were identified according to the Handbook of Hungarian Bryoflora (Orbán—Vajda 1983). After identification, the feregucncy and life strategies of species were recognized. The life strategy categories are those used by During (1979) and the life strategy types of species were recognized according to Orbán (1984). Table 1 contains the frequency data of bryophyte species which occurin the communities examined and Table 2 includes the frequency scores of life strategies.
