The South-Eastern-Bükk is divided into three phytogeographical units. The north-western unit with limestone bedrocks is the highest one and is mainly covered by beech forests (Melitti-, Aconito-Fagetum) and with their varieties with hornbeam. On tops and ridges varieties of linden-ash rocky forests (Tilio-Fraxinetum) are dominant.

The lower unit on the south-east is the largest in extension. On south facing slopes one can find the mosaic-like pattern of communities most typical for the South-Eastern Bükk. These are dry steppe grasslands (Pulsatillo-Festucetum rupicolae), karstic shrub forests (Ceraso-Quercetum) and thermophylous oakwoods (Corno-Quercetum). It is here where these communities reach their largest extension in Bükk Mts. as a whole. The richest in species are communities of the Kisgyőri-Galya Mt. which has an exposed position. Northern slopes are covered with oak-hornbeam forests (Querco-Carpinetum) and sessile oak-turkey oak forests (Quercetum petraeae-cerris).

The smallest unit on the south-west is built up by various bedrocks (mainly shales and limestone) therefore its vegetation is as well the most diverse. The abovementioned thermophylous communities and Tilio-Fraxinetum are typical on limestone while on shales Quercetum petraeae-cerris and acidophylous communities appear. Among the latest ones the most interresting are the acidophylous beech forests (Descampsio-Fagetum) with whortleberry (Vaccinium myrtillus).
