Szerdahelyi, Tibor, Penksza, Károly, Dobolyi, Konstantin Z., Szollát, György, Kapocsi, Judit; Figeczky, Gábor: Vegetation and point-mapping survey in the strictly protected areas of the landscape protection area of the Pilis Mts (Hungary)

Range 35: Nudum-type Melitti-Fagetum stand on a plateau. The stand is approximately 80 years old, almost even-aged without saplings. Range 36: In part A and B an Asperula odorata-type Melitti-Fagetum stand can be found. On the northern corner extremely old Sorbus torminalis individuals have to be mentioned. Part C descends to western direction, Melitti-Fagetum is mixed with Querco petraeae-Carpinetum close to the south peak. Range 37: Part A is a Querco petraeae-Carpinetum mixed with Fagus sylvatica, in some places with patches of Carex pilosa. In the nearby part B its gradual change into a clear Asperula odorata-type Melitti-Fagetum can be seen. Range 38: Similarly to the former range, part A is a Querco petraeae-Carpinetum mixed with Fagus sylvatica, with some Carex pilosa patches. To the east Asperula odorata-type Melitti-Fagetum is being formed gradually, and it is continued to the direction of the hills Kis- és Nagy-Szoplák. In the southern part dry habitat is indicated by the presence of Melica uniflora. Range 39: A large part of the range is a Querco petraeae-Carpinetum stand, with a Carex pilosa-type herb layer at the site facing the valley. On the western edge a nudum-type Melitti-Fagetum stand stretches. The habitat has shallow soil with bare rocks on the surface. The growing rate is low here and Tilia cor data also appears. Range 40: Adjacent to the former range Melitti-Fagetum can be found, where going further less and less bare rocks are seen. In the middle part the herb layer is Asperula odorata-type. On the plateau it transforms into a Melica uniflora-type indicating the drier habitat. Range 41: Part A is mostly Querco petraeae-Carpinetum, on the northern part it is mixed with Fagus sylvatica. On the steep sites with bare rocks the growing rate is lower. Sorbus torminalis and Fraxinus excelsior individuals are mixed one by one. On the southern part it is mixed with Fagus sylvatica, its herb layer is Carex pilosa-type. On a gentle slope Melica uniflora appears. Part B is shared by an old Melitti-Fagetum stand and a Querco petraeaeCarpinetum stand mixed with Fagus sylvatica and Fraxinus excelsior. Range 42: The largest difference in altitude and the most diverse features of the terrain are found here. The western part of the range is Querco petraeaeCarpinetum which stretches along the valley. To the east with the increasing altitude it is transformed into Melitti-Fagetum. Bare rocks and diverse rock formations, two large caves and rock-glaciers make the silviculture difficult. Because of the large angle of slope gradual thinning can be applied as harvesting method for habitat protection. On large areas continuous stands can not be formed due to the rock-glaciers. Scrubs composed of mostly Cotinus are impenetrable at several sites. In connection with this gnawing of animals and treading has also large importance. This degradation is caused mainly by the excessive moufflon population.
