    The present paper is the 13th in a series of papers contributing new floristic data to complement the distribution maps of Atlas Florae Hungariae. We present altogether 1307 new occurrence data to advance our knowledge of the distribution of vascular plants in Hungary. New data are presented for 634 vascular plant species from 256 flora mapping quarter quadrates (CEU). Due to the unevenness of data collection, the data are highly dispersed over the area of Hungary. Most of the presented occurrence data are from the Great Hungarian Plain, the North Hungarian Mountains, and the Little Hungarian Plain regions. The enumeration includes rare native species (e.g., Androsace maxima, Erysimum crepidifolium, Orobanche gracilis, Peucedanum palustre, Pulsatilla zimmermannii, Scopolia carniolica, Vicia biennis), rare or data deficient adventive species (e.g., Euphorbia prostrata, Euphorbia serpens, Lindernia dubia), subspontaneous occurrences of native species (Asplenium scolopendrium, Daphne laureola, Chenopodium opulifolium), species spreading along linear infrastructure (Eleusine indica, Plantago coronopus, Sorghum halepense, Spergularia salina, Tragus racemosus), and also common native species with data deficient distribution maps (Agrostis stolonifera, Bromus benekenii, Bromus japonicus, Carex caryophyllea, Carex divulsa subsp. divulsa, Equisetum ramosissimum, Vulpia myuros).

    In this study we present the current moss and liverwort flora of the Arboretum of Szarvas. The observations were made in 2017, 2019, 2020 and 2021. Altogether 95 bryophyte taxa (7 liverworts and 88 mosses) were identified. Most of them are considered to be common in Hungary, however some species are rare in the Great Hungarian Plain: Lophocolea coadunata, Climacium dendroides, Hylocomiadelphus triquetrus, Pleurozium schreberi, Polytrichum formosum, Rhytidiadelphus squarrosus, Ulota crispula, Zygodon rupestris. These results also confirm the conservational and scientific value of the arboretum.

  • Dry oak woods on the Szentendre Island

    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.

  • Disappearing botanical and cultural heritage of wooden headboard-graveyards in Eastern-Hungary and Transylvania (Romania)

    Degradation or disappearance of natural habitats are global phenomena nowadays, hence the role of small and secondary (seminatural) habitats like cemeteries in preserving natural values are more and more appreciated. The botanical values and burial customs were examined in a total of 51 graveyards in three different regions of Hungary and Romania (10, 19 and 22 graveyards in the North Hungarian Mountains, the Great Hungarian Plain and Transylvania, respectively). Altogether 25 in Hungary legally protected plant species were found, 1.5 protected species per graveyard on average. As we observed, traditional burials with wooden headboards are rapidly superseded by modern burial customs. Based on our non-representative poll (n=102), 90% of citizens on average are satisfied with current conditions in Hungarian graveyards. A two-thirds majority of respondents would prefer more frequent lawn-mowing in graveyards. 75% of respondents prefer modern tombs to traditional graves. Disappearance of old burial customs characterised by the use of wooden headboards (and the simultaneous change in traditional, habitat-friendly practices in graveyards) means not only a loss of cultural values, but threatens the natural biodiversity of graveyards as well.

  • Oak-ash-elm forests in the Nyírség

    This paper presents phytosociological analyses of oak-ash-elm forests of Nyírség, NE Hungary. These climatically azonal forests grow in habitats where the soil is under the continual influence of the groundwater table, which maintains rather mesic conditions. They are particularly rich in Fagetalia elements (Actaea spicataAllium ursinum, Anemone ranunculoides, Asarum europaeum, Athyrium filix-femina, Cardamine bulbifera, Carex pilosa, Cerastium sylvaticum, Chaerophyllum aromaticum, Corydalis cava, Dryopteris filix-mas, Epipactis helleborine agg., Euphorbia amygdaloides, Galeobdolon luteum, Galium odoratum, Hedera helix, Isopyrum thalictroides, Lathraea squamaria, Lathyrus vernus, Lilium martagon, Majanthemum bifolium, Mercurialis perennis, Milium effusum, Polygonatum multiflorum, Pulmonaria officinalis, Ranunculus cassubicus, Salvia glutinosa, Sanicula europaea, Scilla vindobonensis, Stachys sylvatica, Stellaria holostea etc.) typical in the submontane regions of this part of Europe. It is possible that they are remnants of the vegetation dominating the region under the less continental and more moist climate during the Beech phase (2500–800 BC) of the Holocene.
