This preliminary survey of North Korean vegetation is based on phytocoenological data obtained during the fi ve expeditions that took place between 1984 and 1990 (1181 relevés) by Czech and Slovak phytocoenologists. Field analyses and the classifi cation of vegetation were carried out using the Braun-Blanquet approach and methods of hierarchical numerical classifi cation. In the eleven synoptic tables, related to the eleven main groups of biotopes, all distinguished associations and communities are presented and compared. Individual vegetation units are syntaxonomically and nomenclaturally revised. Within the 20 classes (Asteretea tripolii , Bidentetea tripartitae, Cakiletea maritimae, Carici rupestris-Kobresietea bellardii , Glehnietea l ittoralis, Lemnetea, Miscanthetea sinensis, Oryzetea sativae, Phragmito-Magnocaricetea, Plantaginetea majoris, Potametea, Querco-Fagetea crenatae, Rhamno-Prunetea, Robinietea, Rosetea multiflorae, Salicetea sachalinensis, Salsoletea komarovii , Selaginello tamariscini-Potentil letea dickinsii , Stellarietea mediae, Vaccinio-Piceetea), 89 associations and communities are distinguished. Each unit is characterised by the correct name and short paragraphs on the diagnostic species, synmorphology, synecology, intra-association variability, distribution, human infl uence and references used. The zonality of the forest vegetation in North Korea is briefl y characterised.

Transformation processes in countries like Kyrgyzstan often lead to intensifi cation or extensifi cation of grazing on mountain pastures. In order to reveal the impact of livestock grazing on vegetation patterns, we examined traits of dominant and frequent species in four previously classifi ed plant communities. In particular we analysed trait-environment relationships using multivariate RLQ analysis and univariate fourth-corner statistics in order to identify most relevant environmental gradients. Functional Response Groups (FRG’s) of plant taxa were derived from clustered RLQ ordination space, and were subsequently analysed for their proportionality in previously identifi ed plant communities. Plant height, growth form, lateral spread, fl owering time and life cycle showed a high degree of correlation with grazing. RLQ analysis revealed a high differentiation of plant trait values along a grazing gradient on the fi rst RLQ axis. FRG’s matched three of four vegetation types by constancy and fi delity values (phi) well. Thus, trait-based analyses were successfully used to identify functionally similar groups of species with regard to different regimes of grazing pressure.

Traditional vegetation knowledge of herders was studied in the Hortobagy steppe. In this paper (1) the habitat types/vegetation types herders distinguish, (2) the names they use for these folk habitats, (3) the botanical equivalents of folk habitats, and (4) the herders' description of the main vegetation types distinguished by phytosociologists are presented. Ecological anthropological methods such as participant observation, interviews, free listings were used for eliciting herders' knowledge. There were 2239 records of habitat names and features, and 1432 records of the knowledge of habitat requirements of plant species collected from 78 herders. Herders distinguished 47–66 habitat types using 185 names. Many categories were more or less equivalent to the level of plant association, and some described mosaics of habitats. Herders divided the steppe into three large habitat groups: wet habitats (lapos in Hungarian, 16–21 habitat categories), saline habitats (called szik, szikes, 11–16 categories), and habitats found on chernozem soils (called partos, telek, 8-13 categories). Another 10-14 categories were used by them to name habitats in arable areas and settlements. Herders distinguished and described habitats based on their productivity, salinity, wetness, dominant species, relative elevation on the steppe habitat gradient, surface geomorphology, land-use, density of vegetation, and passabilty. We will argue that traditional herders' knowledge can provide new information for scientists, e.g.on local vegetation dynamics and history. Understanding herders' vegetation knowledge, motivations and constraints in herding could also contribute to the improvement of nature conservation management e.g.by making communication between herders and scientists/conservationists more concrete, and perhaps by providing better targets for conservationists and environmental managers. Traditional vegetation knowledge is a neglected part of European culture, and it is fading quickly. An effective collection and understanding of this deep vegetation knowledge can best and most effectively be accomplished by scientists with experience in botany.

The present study provides the first detailed phytosociological description of the plant communities of Hulunbeier grassland, the easternmost part of the Eurasian steppe. Using phytosociological methods, vegetation data were collected from 109 plots in six areas spanning 300 km and covering a large proportion of the east-west axis of Hulunbeier steppe. Five main phytosociological plant communities were identified: meadow steppe of Veronico incanae-Stipetum baicalensis, ruderal vegetation of Cannabi-Sphallerocarpetum gracilis, steppe of Poo attenuatae-Stipetum grandis, heavily grazed steppe of Allium polyrhizum community, and Glycyrrhizo uralensis-Achnatherum splendens. The Poo attenuatae-Stipetum grandis was divided into two subunits: a Potentilla acaulis subassociation and a Caragana microphylla subassociation. The ordination of the communities showed a strong gradient from the drier western steppe to the wetter eastern steppe. Compared with 20 years ago, the zonal floristic composition had drastically changed from S. krylovii being dominant to the salt-tolerant A. polyrhizum and A. splendens becoming dominant. Species richness was lower in the communities nearby water sources suggesting intensive grazing and tramping than in the typical community of the steppe zone. Species richness was lower in the abandoned fields than in adjacent uncultivated sites. These results suggest that both grazing pressure and cultivation had changed the floristic composition and decreased the species richness in the area.

A survey and a formalized phytosociological classification of the marsh vegetation of the class Phragmito-Magno-Caricetea in central Italy is presented. Formal definitions of the majority of wetland associations recorded from the Italian territory were defined using the Cocktail method and applied to a large data set of vegetation plots extracted from the database VegItaly (hosted by the web database system "anArchive"). A total of 43 associations belonging to seven alliances and four orders were recognized. Detrended correspondence analysis (DCA), species indicator values and altitude were used to visualize ecological differences between the associations. Altitude, nutrient status and soil reaction were identified as the main environmental gradients responsible for diversification and distribution of the Phragmito-Magno-Caricetea communities in central Italy.

Vegetation of ephemeral wetlands (class Isoëto-Nano-Juncetea) was studied in the Czech Republic and Slovakia using a formalised classifi cation approach. We analysed a set of phytosociological relevés recorded in the study region comprising 17583 relevés of wetlands and some types of ruderal vegetation. Formal defi nitions of particular associations were completed using a dataset of 1580 relevés, originally assigned by their authors into the Isoëto-Nano-Juncetea class. 770 of these relevés were classifi ed into one of the three alliances (Verbenion supinae, Eleocharition ovatae and Radiolion linoidis) and nine associations: Ranunculetum lateriflori (south-eastern Slovakia), Cerastio-Ranunculetum sardoi (mainly southern Slovakia and southern Moravia), Veronico anagalloidis-Lythretum hyssopifoliae (southern Moravia), Pulicario vulgaris-Menthetum pulegioidis (southern parts of both republics, especially in Slovakia), Polygono-Eleocharitetum ovatae (mainly southern Bohemia and the Bohemian-Moravian Uplands in the Czech Republic), Cyperetum micheliani (both republics), Stellario uliginosae-Isolepidetum setaceae (mainly in southern Bohemia and Bohemian-Moravian Uplands in the Czech Republic, less frequently in Slovakia), Centunculo-Anthoceretum punctati (only two relevés in both republics) and Junco tenageiae-Radioletum linoidis (southern Bohemia in the Czech Republic, Borská lowland in western and Orava region in northern Slovakia). The main environmental gradient of the studied vegetation expressed by Ellenberg indicator values (EIV) is moisture (Spearman correlation coeffi cient with the fi rst DCA axes -0.666, p < 0.001), followed by light (-0.656, p < 0.001). Comparison of clusters based on EIV showed signifi cant differences in several cases, mainly: 1) the signifi cantly lowest EIV for temperature was detected for Stellario uliginosae-Isolepidetum setaceae and Junco tenageiae-Radioletum linoidis; 2) Polygono-Eleocharitetum ovatae had the highest EIV for moisture; and 3) Junco tenageiae-Radioletum linoidis had the lowest EIV for nutrients. Our study is one of the fi rst attempts at formal classifi cation of Isoëto-Nano-Juncetea vegetation in a relatively large area and to compare the ecology of the communities defi ned by this approach.

We studied the aquatic vegetation of bottom-rooted plants, i.e. the class Potametea, in Baikal Siberia, a region in the south of Eastern Siberia. Forty associations were found based on 623 original relevés and 65 relevés from the literature. Six associations (Lemno trisulcae-Sparganietum graminei , Myriophyllo spicati-Potametum compressi , Potametum bottnici , Potametum maackiani, Potametum salicifoli i , Potametum vaginati) are described here for the fi rst time. The names of fi ve syntaxa have been typifi ed. Nine new community-types were recorded for Baikal Siberia. Each association is outlined by its diagnostic, constant and dominant species, structure, ecology and distribution. The regional distribution of each association is shown by grid maps. Large-scale phytogeographical comparison of sets of diagnostic species of Potametea across Northern Eurasia revealed that Baikal Siberia harbours two thirds of the diversity of macrophyte vegetation of Northern Asia and 40% of that of Northern Eurasia. Our study showed that Baikal Siberia’s Euro-Siberian aquatic vegetation gradually declines in species and community richness towards east. The aquatic vegetation was found to be rich in thermophilous plants in the Russian Far East along the lower course of the Amur River.
