“…The nutrient deficient, weak soil profile developed on calcareous sand (Várallyay 1993, Kovács-Láng et al 2000. Nonetheless, the area has many floristic values, characterized by a rich lichen flora (e.g., Cladonia convoluta, Cladonia furcata, Cladonia magyarica, Cladonia rangiformis) (Lőkös and Verseghy 2001, Molnár and Kun 2011, Veres and Csintalan 2017 and some typical endemic plants, e.g., Festuca vaginata, Colchicum arenarium, Dianthus diutinus, Dianthus serotinus, Iris arenaria (Tóth 1996, Molnár 2003, Magyari et al 2010, Molnár and Kun 2011). The study area has been protected and abandoned since 1974, but it was used for grazing and military excersises before protection.…”

“…Pannonian sand steppes or open sand steppes (Natura 2000 code: 6260) are of special importance for the European Union Habitat Directive (92/43/CEE). These dry, nutrientpoor, calcareous sand habitats are home to a large number of rare, endangered or endemic species (Tóth 1996, Lőkös and Verseghy 2001, Molnár 2003, Molnár and Kun 2011, Fekete et al 2014, Veres and Csintalan 2017 and they are very vulnerable to biological invasion (Botta-Dukát 2008). A possible reason of high invasibility of open sand grasslands is the former land use (and the related disturbances) in the past (Botta-Dukát 2008).…”

Invasion impact is conditioned by initial vegetation states

Biological invasion is a crucial problem in the world because of its negative consequences for protected areas. The degradation stage of vegetation might affect the success of invasion. One of the most abundant and threatening invasive species is the common milkweed (Asclepias syriaca L.) which has invaded already 23 countries of Europe and in several habitat types its further spreading is promoted by climate change. Pannonian sand grassland is one of the most threatened habitat by common milkweed invasion. Therefore, invasion in sand grassland vegetation is an important issue. However, the effects of the invasive plant in the open sand grassland are rather controversial. In order to clarify the existing contradictory results, the study was carried out in a strictly protected area, near Fülöpháza (Hungary) in a reserve core area in a UNESCO biosphere reserve. Microcoenological study was applied to determinate the fine-scale community characteristics of non-invaded and invaded stands in natural and seminatural vegetation and data were processed by Juhász-Nagy's information theory models. Shannon diversity of species combinations (compositional diversity) which describes the ways of the coexistence of species, and the number of realized species combinations were used for measuring beta diversity. Differences between stands were analyzed by two-way ANOVA. The maximum compositional diversity of species and main life-forms (annuals, perennials and cryptogams) did not differ significantly between the non-invaded and invaded stands. In contrast, significantly larger characteristic areas of compositional diversity were detected in the invaded stands. Based on these results, it could be concluded that diversity of species combinations did not change but those values have shifted to coarser scales in case of invaded stands. The direction of this change suggests a kind of impoverishment in the presence of Asclepias. Thus, it is worth mentioning from the invasion management point of view that protection of the habitats against disturbance is a more cost-effective and successful way than protection against the establishment or extirpation of invasive species, since disturbance facilitates the invasions throughout the impoverishment of the community.

Data on the pioneer vegetation of the Lake Velence

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.

Szikes területek elterjedése és flórája a Mezőföldön

Szikes területek számottevő területeket foglalnak el az Alföld dunántúli részén, a Mezőföldön. A Velencei-tó és a Sárvíz mente térsége kivételével e területek flórája és vegetációja elkerülte a botanikusok és biogeográfusok figyelmét. E közleményben e szikes területek rövid leírását és az elmúlt 17 év során folytatott botanikai felmérésük eredményeit adom közre. A felsorolásban a növények neveit az érintett település neve és, ha van ilyen, a földrajzi elnevezés, majd a Közép-európai Flóratérképezés négyzethálóján belül annak a négyzetnek a kódja, amelybe a lelőhely esik, valamint néhány faj esetében az első észlelés évszáma követi. A fajok felsorolása betűrendben történik. Az adatok azt mutatják, hogy az egyes szikes talajú területek flórája csupán egy-egy részhalmazát képezi a Sárvíz menti szikesek flórájának, ami feltehetőleg részben a területek fragmentáltságának és a részleges élőhelyvesztésnek tulajdonítható.
