  Hungarian records of nine adventive or invasive algae [Didymosphenia geminata, Nitzschia closterium, Reimeria sinuata, Navicula schroeteri, Pleurosira laevis (Bacillariophyceae); Pediastrum simplex (Chlorophyceae), Cylindrospermopsis raciborskii, Cuspidothrix issatschenkoi, Sphaerospermopsis aphanizomenoides (Cyanobacteria)] are presented. Navicula schroeteri Meister is a new species for the Hungarian flora. Although the observed distribution patterns of these species were very different, the increasing frequency of their appearance indicates significant effect of climate change on abiotic environment of inland waters, such as the increase in water temperature, increase in salt concentration, and eutrophication. The significance of continuous biomonitoring is emphasized, which, through the recognition of natural and human-induced changes in species composition of algae, or the appearance and rapid expansion of non-indigenous species, can detect environmental changes of inland waters.

  The hay meadows and protective forest strips of the Kámon and Herény source water protection areas in the northwestern part of Szombathely have been in good natural condition for decades. By harbouring populations of protected plant species (Orchis morio, Pyrola rotundifolia, Cephalanthera longifolia, Epipactis helleborine and Ophioglossum vulgatum), these areas resemble natural habitats found nearby in the Kőszeg Mountains and the Őrség National Park.  The good semi-natural condition can be attributed to the lack of regular mowing in the case of meadows and the lack of disturbance in the case of forest strips. In recent years, however, the area have been exposed to increasing human disturbance (car and motorcycle off-roading), so it may be timely to initiate legal protection. This short case study indicates that properly managed source water protection areas can play an important role in the conservation of semi-natural habitats, rare and protected plant species and the associated fauna.

  The current paper is the sixth one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 389 vascular plant taxa from 117 flora mapping quadrates (CEU) are provided. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts and from the city of Szolnok and Western Hungary. Occurrence data of rare native taxa (including data of Equisetum fluviatile, Galium rivale, Gladiolus imbricatus, Hypericum maculatum, Persicaria bistorta, Potentilla inclinata, Ranunculus lingua, Rhinanthus rumelicus, Trifolium fragiferum subsp. bonannii, Viola pumila), rare or data-deficient alien taxa (e.g. Amaranthus blitum subsp. blitum, Cymbalaria muralis, Elymus elongatus, Euphorbia peplus, Heracleum sosnowskyi, Impatiens balfourii, Lepidium densiflorum, Rhus typhina, Telekia speciosa), as well as frequent but more or less underrepresented taxa (e.g. Carex otrubae, Chenopodium polyspermum, Crepis tectorum, Filipendula vulgaris, Petrorhagia prolifera, Poa palustris) are also enumerated. In case of the most common species we provided the CEU codes only.
