  • Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)
    189–194
    Views:
    136

    Gagea minima (L.) Ker Gawl. is a Eurasian bulbous species. It occurs sporadically in Hun­gary, but so far only one current occurrence is known from the Western Transdanubia. In recent years, a large metapopulation has been found in a 15 km long section of the Sorok stream. Its habitat is the high sandy bank above the stream, where it lives mostly in nitrophilous vegetation under non-native tree species. Its long-term persistence in this secondary habitat may have been facilitated by its bulbs, which may have been regularly dispersed by periodic disturbance. Myrmecochory may also have played a role in the local establishment of subpopulations. A number of recently found populations indicate that data on the distribution of the species is still incomplete. The lack of data is probably due to its short flowering period and relative inconspicuousness. Gagea minima is considered a valuable relict species in the altered environment of the Sorok stream and its surroundings.

  • Seed dispersal and habitat preference of the endangered Lesser White-fronted Goose (Anser erythropus L.) and larger goose species in the Hortobágy National Park

    Several studies found that waterfowl are important endozoochorous dispersal vectors for plant species. Germination of the seed content of their droppings provides valuable information on their diet and also on their role in seed dispersal. Our aim was to analyse the seed dispersal potential of the critically endangered habitat-specialist Lesser White-fronted Goose (Anser erythropus) in their autumn and spring staging areas in Hortobágy National Park. The study was supported by the LIFE10-NAT/GR/000638 project. We also studied the seed dispersal potential of larger generalist goose species foraging in the same areas, such as Greater White-Fronted Goose (Anser albifrons Scopoli) and Greylag Goose (Anser anser L.). We asked the following questions: (i) Which habitat types are the most frequently used by Lesser White-fronted Goose and larger goose species? (ii) Is the different habitat preference of Lesser White-fronted Goose and larger goose species reflected in the seed content of their droppings? (iii) Are there seasonal differences between the seed content of spring and autumn droppings? We identified the most frequently used feeding habitats. We collected 40 droppings of Lesser White-fronted Goose and larger goose species per site in April and October 2012, in total we collected 720 droppings per species. Droppings were concentrated and spread on trays filled with sterilised potting soil. Samples were germinated in a greenhouse from April to November 2013. In total we germinated 21 plant species from the goose droppings, which suggests that goose species play an important role in seed dispersal. We found that Lesser White-fronted Goose dispersed more species typical to alkali habitats, and fewer weeds compared to larger goose species. Lesser White-fronted Goose and larger goose species used a wide range of feeding habitats, thus, they play an important role in dispersing seeds between habitats along a moisture gradient. Total species number and species number of plant functional groups were higher in autumn droppings. Seed content of the droppings suggests that Lesser White-fronted Goose is confined to natural habitats, thus for the effective protection of this critically endangered species it is crucial to preserve its natural feeding habitats.

  • Natural values of Mt Somsich near Villány, threatening factors and necessary conservation actions

    Although Mt Somsich is very rich in natural values, it is still a poorly-known part of the Villány Mts. Apart from a few scattered floristic data and a short habitat description, its vegetation is virtually unexplored. The aim of this paper is to characterize the natural and semi-natural habitats of Mt Somsich, give the current population sizes of the protected plant species, survey their threats, and offer suggestions for further conservation activities. Disregarding the totally artificial habitats, five habitat types were distinguished on Mt Somsich, of which the pubescent oak scrub is the most valuable. A total of 15 protected plant species have been reported so far, of which 11 are currently recorded on Mt Somsich. The local wildlife is affected by loss and fragmentation of habitats as well as illegal activities. The negative influences cannot be fully eliminated, but could be minimized.

  • New occurrence of Myricaria germanica in a secondary habitat (NE Hungary)

    In this paper, we report a new occurrence of Myricaria germanica (L.) Desf in a secondary habitat from the north-eastern part of Hungary, from the edge of the Bükk Mountains, in a slag dump in Miskolc. The plant is established on a steep wall formed during the extraction of slag. Due to the erosion of the wall, occasionally a few plants fall off. The age of the dead specimens is between 5 and 13 years, based on their growth rings. The population of about 50 individuals is the largest (but perhaps the only) living population of the species in Hungary. Other rare and protected species (Epilobium dodonaei Vill., Dysphania botrys (L.) Mosyakin & Clemants, Dryopteris carthusiana (Vill.) H.P. Fuchs, Polystichum aculeatum (L.) Roth ex Mert.) have also been found in the slag heap area.

  • The occurrence of Pterygoneurum squamosum Segarra et Kürschner on a reclaimed waste storage near town Győr (NW Hungary)

    In the article a new locality, range map and habitat description of Pterygoneurum squamosum is provided from Hungary. Differently from up to the present known localities, the moss was found on anthropogenic habitat, eroded and clayey soil surface. Considering the climatic and soil conditions there, probably this rare Mediterranean species has wider ecological tolerance, so we come across it on further man-made habitats, as well as on loess walls.

  • Contributions to the algal flora of a recently-formed peat moss bog near Kőszeg (W Hungary)

    The Alsó-erdő peat bog near Kőszeg has undergone a significant transformation since its first mention in the literature. In addition to the original single patch, a smaller one appeared a few decades later. The process did not stop and a third unit, discussed here, was formed. The succession of its macrovegetation towards the typical peat moss association started slowly but surely, due to balanced water regime and other optimal environmental conditions. The process is more advanced for the algal vegetation, which shows the characteristics of peat bogs already. The high species diversity found makes the habitat highly valuable itself. Although a special, unique algal species has not been found in previous studies, 27 Desmidiales taxa listed as endangered occur sometimes with high density and make the habitat even more valuable. Based on our results, the area deserves special attention both from the habitat conservation and research point of view. At the same time, its further monitoring can provide crucial information for exploring and understanding the succession of similar habitats, and thereby for their more efficient protection.

  • On the former occurrence of Calla palustris in Hungary

    The origin of a more than 150 years old herbarium specimen of Calla palustris L. stored in JPU is reconsidered in this study. According to the information on its label, the specimen was collected in 1856 at Lake Velence, close to Székesfehérvár city (central Hungary). Some Hungarian botanists are skeptical about the authenticity of this record. Based on the current occurrences of some remarkable swamp species (e.g. Carex pseudocyperus, Liparis loeselii, Sphagnum spp.) and habitat types (e.g. willow carrs and swamp forests) at the lake, as well as the habitat preference of bog arum, there is no reason to question the former occurrence of the species here or even in other Hungarian localities. The content and accuracy of the examined voucher meet the expectations of floristic data. However, in the absence of recent data the species can be considered extinct from Hungary.

  • Distribution of Campylopus introflexus (Hedw.) Brid. in Hungary

    Based on field work data collected in 2013–2014, the authors generated a map of the current distribution of Campylopus introflexus for Hungary. Besides the coordinates and geographic name of the localities, an estimated size of the population, the type of habitat and substrate, the co-occurring moss species and affected vegetation types were also recorded. Altogether, 18 stands were found in 8 geographical regions of Hungary, in some cases Campylopus introflexus was found to be a new species record for the moss flora of the respective region (e.g. Dunántúli-dombság, Nyugatmagyarországi peremvidék). In addition to the pine plantations from where it was detected formerly, the mixed deciduous-coniferous forests, the acidophilous oak woodlands and man-made habitats were found to be also proper habitats for this moss taxon. Earlier data mainly originated from pine deadwood, the recently discovered stands were found on acidic soil surfaces. The most important cooccurring moss species were the followings: Hypnum cupressiforme, Polytrichum piliferum, P. formosum, Pohlia nutans and Ceratodon purpureus. Campylopus introflexus had prominently high coverage in the acidophilous oak forests of the Mecsek Mts, where it occurs on acidic sandstone covered with a thin debris of the bedrock. This neophyte moss is widely distributed in Hungary, and has stable populations. Further expansion is expected in the subatlantic and submountain regions of the country, and in regions characterised by acidic soils and pine plantations.

  • Distribution of Calamagrostis stricta (Timm) Koeler in the Southern Nyírség (E Hungary)

    This study presents the current distribution of narrow small-reed (Calamagrostis stricta (Timm) Koeler) in the southern part of Nyírség (E Hungary). Beyond the efforts to confirm previously known occurrences, a high number of potential habitats were surveyed. Field work was carried out from late autumn to early spring taking advantage of the better perceptibility of dry foliage. The species was detected in 43 localities inside the boundary of 15 settlements, which considerably exceeded our expectations. Although most of the populations were quite small, in some cases their extent reached over 1000 m².  Populations around the settlements of Penészlek, Fülöp and Nyírábrány were the most frequent and the largest in size. The endangered status of the species is caused by the insufficient water supply of suitable habitats in the region. Besides habitat change, desiccation can also amplify the effect of anthropogenic disturbances (e.g. ploughing, fishpond development), which poses a further threat to populations.

  • Habitats and protected plants of Cuha-valley (Bakony Mts, W-Hungary)

    Floristic data were collected and habitat mapping was performed between 2009 and 2011 in the valley of Cuha-creek. During the field work occurrences of 423 vascular plant species (including 31 protected taxa) were recorded. Potentilla indica represents a previously unknown alien taxa of the study area. The dominant vegetation type of the Cuha-valley is beech forest. Further characteristic, important habitats are scree, ravine and hilltop forests. On the southern part of the valley – in close proximity of the Cuha-creek – expansion of several alien plants (Impatiens glandulifera, Fallopia spp., Heracleum mantegazzianum) were observed.

  • Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)

    This paper reports new floristic data of 367 taxa (365 species and two hybrids) from the foothill region of Bükk Mts. ('Bükkalja', NE-Hungary) based on 5470 field collected data records. The data was collected between 1997–2014 and supplemented with herbaria (altogether 344 herbaria sheets). Data evaluation was based on the comprehensive Bükk Flora of András Vojtkó and further papers. Altogether 45 species were registered as previously unreported from the area, whereas three species had old data (Acer negundoElaeagnus angustifoliaXanthium strumarium). Out of the newly registered species six native species inhabits natural habitats (Carex flaccaCeratocephala testiculataGlycerrhiza echinata, Gypsophila paniculataKochia lanifloraMarrubium vulgare), whereas five species represents the weed flora (Anthemis ruthenicaChenopodium ficifoliumEragrostis pilosaSenecio vernalisXanthium strumarium). The majority of the newly observed species are adventives. Five species were also regarded as recent introduction regionally, although they are native in the country (mostly lowland species: Crypsis alopecuroidesLimonium gmelini subsp. hungaricumSalsola kaliScirpoides holoschoenusTrifolium angulatum). Typical threats observed are landscape and habitat degradation by invasive alien species out of which 11 are newly added. Mass occurrences were detected for the following invasive alien species: Bidens frondosaImpatiens glanduliferaPhytolacca esculentaXanthium italicum. 43 species are also registered, which did not have recently published data from the area. These species include more native elements representing different habitat preferences (dry grasslands, wet meadows, forest and weeds). In case of 65 species the unravelled new occurrences increased significantly, thus contributed to the clarification of their distribution pattern. It was found that the floristic data accumulated on a decade-scale are not sufficient for the analysis of floristic trends, but could serve as a good basis for surveying floristic gradients between the mountainous and lowland areas.

  • Lactuca tatarica (Asteraceae), a new species for the Hungarian alien flora

    The first occurrence of blue lettuce (Lactuca tatarica (L.) C.A. Mey.) is reported from Hun­ga­ry. Information on its taxonomy, morphology, distribution, habitat preference and nature conservation aspects is presented. The European local spread of this Eurasian and North American species started at the end of the 1800s. The first localities were reported from the shores of the Baltic and North Sea. Its alien occurrences in inland European regions have been noticed since the 1920s. As L. tatarica have pre­viously been known from the neighbouring territories of Slovakia and Austria, its appearance in Hun­gary is not at all unexpected. However, the species was found (August 2018) in the southern part of Csongrád county, i.e. far away from the above-mentioned countries. Due to the species’ habitat preference (ruderal ground), ecological requirements and successful vegetative propagation, which correspond to foreign observations, its future spread is highly probable.

    Herbarium revisions and recent field observations revealed the occurrence of Viola collina Besser in the Bükk and Uppony Mts. (northern Hungary). This species has not been reported from the North Hungarian Mountains thus far. Altogether 94 localities of V. collina have been recorded in that region between 2007 and 2014. A map of the species’ local distribution is provided. Local habitat preferences of V. collina are briefly discussed.

  • The Sea milkwort (Glaux maritima) in the Carpathian Basin

    Sea milkwort (Glaux maritima L.) is a broadly distributed species in the northern hemi­sphere, inhabiting primarily maritime habitats from the arctic to the temperate zones. It is also found inland in semi-arid and arid regions with saline soils. Its status in the Carpathian Basin has become very uncertain owing to the lack of known extant populations. To evaluate its current status, I review all known occurrences within the Carpathian Basin where this species has been recorded or collected, and report five new localities of the species in Hungary, all in the western part of the Great Hungarian Plain. I also analyze habitat relationships of the species using traditional phytosociological relevés. Review of species distribution data in the Carpathian Basin revealed that sea milkwort has undergone severe reduction in population number and disappeared from many localities. Currently, only a few populations can be found in this region: the Northern Carpathians in Slovakia and the western part of the Great Plain in Hungary. In Transylvania (Romania), only a single population has been reported recently suggesting the critical status of the species there. Features of the habitats confirm the halophytic nature of the species and its fidelity to wet saline meadows. Its common accompanying species are mostly broadly distributed, salt-tolerant plants. Heterogeneity of the samples in species composition suggests that sea milkwort is not a habitat-specialist species. Several of its common associates in Hungary are also found in sea milkwort habitats in Mongolia, Asia and Utah, North America. Based on the available evidence, sea milkwort shall be considered a severely threatened plant in the Carpathian Basin. Characteristics of the vegetation in its habitats do not explain its occurrence in mountainous environments.

  • Contributions to the Atlas Florae Hungariae VIII.

    The current paper is the 8th in the series aiming to contribute with new distribution data to the maps published quite recently in Atlas Florae Hungariae. Distribution data of 539 plant taxa from 157 flora mapping units is presented in this study, most of them are located in the western half of the country. As a result of systematic surveys, more than 190 new species were found in a single flora mapping quadrat. In another survey along some asphalted roadsides Puccinellia distans was found as a new species for 68 flora mapping grid units. All these indicate the necessity of further systematic research and publication of floristic results in papers like the “Contributions…” series. Most of the enumerated taxa are frequent, treated usually as weeds, but some of them are sparse and scattered or rare in Hungary (e.g. Nigella arvensisVaccaria hispanica, Rumex pulcher, Urtica urens), and in some cases they are legally protected plants in Hungary (e.g. Asplenium adiantum-nigrumDryopteris affinisGymnocarpium dryopteris and Huperzia selago). We also listed some casual alien plants and naturalized species that were not mentioned in the last neophyte list of Hungary (e.g. Acer cissifoliumCyperus alternifoliusGaillardia aristataGalanthus elwesii). In the Outlook we pointed out the insufficient survey of some synanthropic (urban) habitat types in Hungary, like verges, gardens and flowerbeds that can be the hotbed of established species or can serve as stepping stones for potential invaders.

    This paper reports the second Hungarian synanthropic occurrence of the rare Myricaria germanica. One flowering individual was found in a gravel pit near Hejőpapi (NE Hungary). The closest known population of the species is 60 km far from newly found locality. This occurrence indicates effectivness of anemochory. It seems, that abandoned gravel pits may be potential habitats of this threataned shub species.

    Records of 26 vascular plant species from the territory of Sopron Mountains (16 species) and Sopron Basin (11 species) are presented. Our field works (between 2014 and 2020) focused on some localities at the eastern and southern parts of the region. Tetragonolobus maritimus is new for the Sopron Mts, whereas Ajuga chamaepithys and Lycopsis arvensis are new for the Hungarian part of the hills. Some protected plants like Agrostemma githago, Gentianopsis ciliata and Sesleria uliginosa were rediscovered in the region. Comments about all species and their local chorology are added. A remarkable degradation process of bogs around Harka village, caused mainly by insufficient water supply of meadows, was observed. The spread of occurrences of several naturalized weed such as Aegilops cylindrica, Galium parisiense, Geranium rotundifolium, Kochia scoparia, Lepidium virginicum, Oenothera salicifolia, Sagina apetala subsp. apetala and Verbascum lychnitis was noticed. The most surprising observations refer to Galium parisiense; the spread of the species by transport had no precedent in Hungary before.

  • Monitoring of the Apium repens population near Császártöltés (2006–2015)

    Detailed botanical surveys were carried out to monitor the population size of Apium repens in the Vörös-mocsár nature protection area (located in S Hungary, Császártöltés). We found a clear correlation between the water status and the land use type and management of the habitats and the size of the Apium repens population. Apium repens is a Nanocyperion-species, which simultaneously requires wet and open surfaces. Its population shrinks, becomes latent or disappears if its habitat dries out or any other radical transformation happens, like too much leaf litter, closure of the vegetation, or succession on the open peat surfaces. Proper management (water retention, extensive grazing, mowing, open peat surface) has a very positive effect on the populations in a short time, even within a growing season. The research was implemented within the framework of the National Biodiversity Monitoring System, in cooperation with the Kiskunság National Park Directorate.

    The study presents a number of new data on the fern flora of South Nyírség, and reviews all available literature and herbarium fern records from the area. A total of 19 Pteridopsida species were detected in the region. The hart's tongue fern (Asplenium scolopendrium) and the soft shield fern (Polystichum setiferum) were hitherto unknown in the whole Nyírség region (flora district “Nyírségense”). The broad buckler-fern (Dryopteris dilatata), scaly male fern (Dryopteris affinis) and floating fern (Salvinia natans) are new records to the area of South Nyírség. Dryopteris dilatata has been found in a surprisingly great number of localities. Some morphological characters facilitating identification of this species are also discussed. The local pine plantations, fens, carrs and humid deciduous forests are important habitats for ferns. In some localities the co-occurrence of 5-6 fern species were observed. The increasing aridity in the last decade is posing a serious threat to ferns in the area.

  • Rediscovery of Crepis mollis (Jacq.) Asch. subsp. hieracioides (Waldst. & Kit.) Domin in Hungary

    Crepis hieracioides (= C. mollis subsp. hieracioides) was described from the Bakony Mts. (Western Hungary) by Pál Kitaibel more than 200 years ago. His record has been the single one of this taxon from the territory of present-day Hungary thus far. In the second half of the 20th century this taxon was either reported as ‘extinct’ or was plainly ignored in the Hungarian literature. This paper reports about the recent rediscovery of C. mollis subsp. hieracioides in the Bakony Mts., specifically in the ‘Bakonyalja’ region (Devecser: Széki-erdő). The habitat is characterised, and the regional phytogeographical significance of this taxon is emphasised.

  • Data on the pioneer vegetation of the Lake Velence
    203–208
    Views:

    Lake Velence is one of Hungary's largest saline lakes. Part of its natural dynamics is that certain parts of the lake bed regularly dry out, providing pioneer surfaces suitable for the emergence of plants of the mudflats and drying (saline) ponds. During the particularly dry year of 2022, the water level was per­manently and significantly low, allowing to study the vegetation of the dry lake bed. In the first half of the last century, the natural vegetation of the lakeshore (including salt steppes) was studied, but there are very few records of the pioneer species of the lake bed. The salt steppes around the lake have now largely declined, but due to low water levels, some of their characteristic species are still present in the lake bed (though, usually in low number of individuals). Examples include Crypsis aculeata, Cyperus pannonicus, Suaeda pannonica, the once abundant Suaeda prostrata, and the previously rare Crypsis schoenoides and Spergularia salina. Spergularia maritima was once widespread but currently not found in the lake bed. Although, Schoenoplectus litoralis is not a member of the ephemeral vegetation, but is a characteristic plant of the littoral zone of Lake Velence. This species probably appeared therein the middle of the last century and is currently spreading.

  • The degradation of hygrophilous plant associations of the Nyárjas Lake (E Hungary)

    The Nyárjas Lake (located near Kállósemjén, East Hungary) was one of the most typical bogs in the Nyírség until the early 1980’s. Most of its area was covered by the association of Carici-Menyanthetum. The number of species characteristic to the mentioned association was generally high. As the climate became drier, hotter and were characterised by higher magnitude of extremities, the water coverage became no longer as permanent. This resulted that the Menyanthes trifoliata and Listera ovata became extinct by 2000. Lemno-Potamea species were not found after 2010. Bidentetalia, Calystegietalia, Chenopodietea and Secalietea species became more prevalent, particularly in drier periods, and locations where Carici-Menyanthetum used to be characteristic. Cirsium arvense in the mid-1990’s and that of Urtica dioica in the mid-2010’s became dramatically abundant. Both the number and coverage of species indicating habitat degradation have increased. The composition of wet meadow plant associations shifted towards the drier Arrhenatheretea. A moderate revitalisation of wetland associations was, however, observed coinciding years with higher precipitation.

  • Orchids of poplar plantations – a review
    102–117

    There are literature data on the occurrence of 26 orchid species and 2 hybrids in economic poplar plantations from 13 European countries. The occurrence of 4 additional species in poplar plantations in 3 countries is proved by sources on the World Wide Web. The most widespread orchids in the poplar plantations are the rhizomatous, partial myco-heterotroph Cephalanthera and Epipactis species. Their importance is enhanced by the fact that most of the known populations of some species with a relatively narrow distribution range (Epipactis bugacensis, E. campeadorii, E. fibri, E. tallosii, E. zaupolensis) are known in poplar plantations. Cultivated poplar monocultures are likely to provide habitat for further orchids in other countries too. Most of the published papers are limited to floristic data from a single or a few plantations. Longer-term observations are only available from Poland, thanks to the work of W. Adamowski, and these suggest that populations may persist for decades and even increase dynamically. The size of orchid populations in some cases can reach thousands or even hundreds of thousands of individuals. Orchids can appear earliest in (4–)7–8 years old plantations. Very little is known about how the cultivation, structure, soil conditions and the poplar cultivars influence the presence of orchids. Mycorrhizal interactions of poplars and orchids may play a key role in this process, but the available knowledge is very limited. Furthermore, little is known about how the economic use of plantations can be reconciled with the long-term maintenance of orchid populations.
