ABSTRACT
The paper brings results from the research of vegetation in forest geobiocenoses of the Kněhyně-Čertův mlýn National Nature Reserve. The research was made on permanent and complementary research plots. Synthetic phytocoenological tables were presented for six most frequently occurring groups of geobiocoene types only with a brief description of their ecological and chorological character- istics (Sorbi-Piceeta humilia, Sorbi-Piceeta, Abieti-Fageta piceae typica, Fageta abietino-pi- ceosa, Abieti-Fageta piceae and Abieti-Fageta aceris superiora). The occurrence of Sorbus aucuparia is characteristic of all groups of geobiocoene types. Species with a high constancy in all groups of geobiocoene types are for example Athyrium distentifo- lium, Avenella flexuosa, Calamagrostis arundinacea, Dryopteris dilatata, Luzula sylvatica, Oxalis acetosella, Polygonatum verticillatum and Rubus idaeus and species with a high coverage are Athyrium distentifolium, Calamagrostis arundinacea, Oxalis acetosella, Rubus idaeus and Vaccinium myrtillus. The results show that vegetation structure is a good indicator of abiotic conditions.
