  The present study reports the occurrence data of 54 vascular plant taxa, collected at various localities in Hungary during floristic, vegetation and ecological field surveys between 2000 and 2013. In some cases, phytosociological relevés were prepared to characterize the local coenological properties of the species. Many of these species are included in the „Red list of the vascular flora of Hungary” (e.g. Carthamus lanatus, Sedum caespitosum, Spiranthes spiralis and Trifolium micranthum). Some of them (e.g. Apium repens, Dianthus diutinus, Epipactis bugacensis and Ranunculus psilostachys) are rarities in the whole country. Our findings suggest that conservationists should focus not only on the maintenance of semi-natural habitats but also on the investigation of secondary habitats (e.g. river embankments, temporary pools on arable fields) in order to maintain the total species diversity of the landscape.

  During a bryofloristical investigation in the vicinity of Ómassa (Miskolc) in the Bükk Mountains (NE Hungary), three montane-boreal bryophyte species new to the Hungarian bryoflora were collected. Encalypta spathulata Müll.Hal. was found on the ledges of limestone cliffs of Vörös-kő Hill as well as on the rocky debris among roots of a fallen tree lying under the cliffs. Hydrogonium croceum (Brid.) Jan Kučera and Orthothecium rufescens (Dicks. ex Brid.) Schimp. were found in the crevices of dolomite cliffs on the north-facing steep slope of Jávor Hill. While the latter two species are widespread in European Mountains, E. spathulata is considered to be a rare species, and is assessed as ‘Vulnerable’ in the IUCN red list.

  The western border region of Hungary, including Kőszeg and its surroundings, is a poorly documented region from an algal point of view. The first reason for this is that the major standing water bodies found here are all artificial and relatively young in age. However, in the absence of other natural water bodies, they are important as potential wetland habitats, as is the information needed to conserve them. The present paper is the first to describe the algal flora of Téglagyári-tó in Kőszeg in the context of the planned process of processing lakes and reservoirs in the area. Despite its small size and the distur­bance caused by its recreational use, Téglagyári-tó is a species-rich, highly diverse habitat in terms of algal diversity. The Chlorophyta division accounts for the majority of the species recorded, but the Charopyta, Euglenophyta and Heterocontophyta divisions also make a significant contribution. Its value is particu­larly enhanced by rare species (e.g. Stauridium privum, Cosmarium sinostegos var. obtusius), not to ment­ion the red-listed endangered species (Cosmarium anceps, Cylindrocystis brebissonii, Euastrum bidentatum, Euastrum denticulatum, Penium spirostriolatum, Staurastrum oxyacanthum, Staurastrum tetracerum). A special feature is the presence of desmids (Euastrum biverrucosum, Euastrum minimum, Staurastrum levanderi var. hollandicum), which are not yet recorded in the region, and which colonise the slightly alka­line mesotrophic environment of the lake, otherwise known from a more acidic eutrophic environment. As a curiosity, Entomoneis ornata should be mentioned, which was identified in an environment associa­ted with higher salinity waters and only moderately loaded with inorganic nutrients.

  This is the first bryofloristic study in the Martonvásár manor park. In our survey in 2015, 56 species (6 liverworts and 50 mosses) were found in the park. Most of them are considered to be common in Hungary, but an endangered (Eurhynchium speciosum), a vulnerable (Orthotrichum patens) and five near-threatened species (Aphanorrhegma patens, Orthotrichum obtusifolium, Orthotrichum pumilum, Pseudocrossidium revolutum, Riccia cavernosa) were also found. These results point out the nature conservation value of the manor park.
