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)

maintaining the habitat of any rare, protected species). Protected species are: Adonis vernalis, Aster amellus, Iris graminea, Iris variegata, Stipa pulcherrima, Sempervivum hirtum and Dictamnus albus. Pilisszentlélek Range 8: Beech forest and Querco petraeae-Carpinetum mixed with Fagus sylvatica on damp soil. The shrub layer is missing, type-indicating plant is predominantly Asperula odorata, in some places Mercurialis perennis, or missing (nudum-type). Range 9: A very steep (45-60°) hillside with N-NE exposure. Part A is an Asperula odorata-type Querco petraeae-Carpinetum association mixed with Fagus sylvatica. Part B is mostly an Asperula odorata-type Querco petraeaeCarpinetum, but in the upper third Melica uniflora, and Mercurialis perennis and Carex pilosa patches are also present. The soil is shallow and sometimes rocky, the forest is partly grown from coppice, but the elements of Tilio-Fraxinetum can be found as well, for example Fraxinus excelsior, Tilia cordata, Acer pseudoplatanus and Ulmus glabra. The threat of soil erosion has to be considered in management practice. Range 10: The northern part of the range is a Melica uniflora-type, the southern part is an Asperula odorata-type Querco petraeae-Carpinetum. In some places the Carex pilosa-type is also present. In part A Pinus sylvestris is mixed in Querco petraeae-Carpinetum with lots of died or decaying individuals. In the herb layer of the range Galium aparine and Urtica dioica have increased cover (in some places occurring in great quantities), which is the joint result of the large game stock and forest thinning. Extensive game stock is also indicated by the treading, gnawing and dung around the feeder. Esztergom, Nagy-Cserép es-tető (Arpád-vár) Range 28B: The bedrock is andésite, the soil is shallow, detrital. The southern-southwestern slope of the hill is covered with Corno-Quercetum pubescentipetraeae, and the upper part with rocky grassland patches. On the rocky parts the soil is missing in many places, the foot of the hill is very detrital therefore the forests has to be maintained for the protection of soil. Range 30: In the northern part of the range Asperula odorata-type, in the southern part Melica uniflora-type Querco petraeae-Carpinetum and MelittiFagetum can be found, in some places Carex pilosa-type. is also present. These three type-indicating species occur together in many cases. Range 31: Tilio-Fraxinetum covers the steep, rocky, northern hillside called Háromszáz garádics. In other parts of the range mainly Asperula odorata-type, in smaller amount Melica uniflora-type Querco petraeae-Carpinetum can be found. The Tilio-Fraxinetum forest of Háromszáz garádics requires careful silviculture.
