  The phytosociological characteristics of the oak woods on the Szentendre Island were first studied 70 years ago. We conducted a follow-up study to determine the phytosociological relationships of theses woods and assess their possible changes over time. We found that these woods are most similar in their phytosociological characteristics to the closed pedunculate oak forests occurring in the high floodplain in the Szigetköz area (Melico nutantis-Quercetum roboris) along the Danube. Our results also showed a marked increase in the proportion of natural weeds, introduced species and invasive aliens in the studied woods.

  We studied the phytosociological characteristics of hornbeam and turkey oak dominated forests growing on sand at the southwestern foot of the Pilis Mountains. Here we present the results of analyses of 10 relevés of each community. The species composition of the hornbeam forest samples is characterized by a relatively high proportion of Fagetalia species. Notable species in the community are Aconitun vulparia, Berberis vulgaris, Epipactis helleborine agg., Galanthus nivalis, Geranium lucidum, Lilium martagon, Omphalodes scorpioides, Piptatherum virescens, Primula veris, Scilla vindobonensis, Sorbus aria agg., S. domestica, Veratrum nigrum, and Waldsteinia geoides. In the turkey oak forests, species characteristic of the class Quercetea pubescentis-petraeae have the hig­hest proportion. Notable and locally typical species occurring in the community are Anthericum ramo­sum, Digitalis grandiflora, Iris variegata, Piptatherum virescens, Primula veris, Achillea distans, Dictam­nus albus, Galanthus nivalis, Lonicera xylosteum, Scilla vindobonensis, Sorbus domestica, Veratrum nigrum, as well as Lunaria annua and Tilia tomentosa that are possibly introduced here. Based on the results of statistical analyses, the two forest communities are best identified with the associations named Corydali pumilae-Carpinetum and Fraxino orno-Quercetum cerridis, both occurring in the Transdanubian Mountain Range.
