The authors distinguish two variants of syntaxonomical analysis. The first one is a classical analysis with creation the complete syntaxonomical hierarchy. The second variant is non-classical analysis based on the “deductive” method of vegetation classification by K. Kopečky and S. Hejny. It has the reduced syntaxonomical hierarchy. The principal ways in making syntaxonomical decisions on classical analysis are formulized as follows: classical dichotomy, the usage of absence criteria, overlapping of diagnostic combinations, and etc. The rules for distinguishing of basal and derivate plant communities which have the transitional features, referring them to one or two higher units, are formulated. It is emphasized that the “deductive” method is the most acceptable for classification of synanthropic serial vegetation with low species richness.

The 2nd international scientific conference «Fundamental problems of vegetation classification» took place at the Nikitskiy Botanical Garden (Yalta, Republic of Crimea, Russia) on 15–20 September 2019. There were 56 participants from 33 cities and 43 research organizations in Russia. The conference was mostly focused on reviewing the success in classification of the vegetation done by Russian scientists in the past three years. The reports covered various topics such as classification, description of new syntaxonomical units, geobotanical mapping for different territories and types of vegetation, studies of space-time dynamics of plant communities. The final discussion on the last day covered problems yet to be solved: establishment of the Russian Prodromus and the National archive of vegetation, complications of higher education in the profile of geobotany, and the issue of the data leakage to foreign scientific journals. In conclusion, it was announced that the 3rd conference in Nikitskiy Botanical Garden will be held in 2022.

Diversity of plant communities in the nature reserve “Privolzhskaya Forest-Steppe”, Ostrovtsovsky area, is analyzed on the basis of the large-scale vegetation mapping data from 2000. The plant community classi­fication based on the Russian ecologic-phytocoenotic approach is carried out. 12 plant formations and 21 associations are distinguished according to dominant species and a combination of ecologic-phytocoenotic groups of species. A list of vegetation classification units as well as the characteristics of theshrub and woody communities are given in this paper.

<em>Iva xanthiifolia</em> Nutt., a north-American therophyte has been recorded in Warsaw only for the last 25-40 years. Here, it occurs as a ruderal epoecophyte. It may be considered as an invasive species in the town as it spreads very quickly. The paper represents the attempt at the determination of the coenological amplitude of <em>Iva xanthiifolia</em> Nutt. It also considers syntaxonomic affiliation of the communities with this species on the grounds of the deductive method of syntaxonomic classification of anthropogenic plant communities.

This article is the second part of the series of publications on vegetation classification of communities with invasive species in the South Urals (Abramova, 2011). The communities with a presence of two aggressive species of North American origin such as Cyclachaena xanthiifolia (Nutt.) Fresen. and Xanthium albinum (Widd.) H. Scholz. are presented. Both species are included in “The black book of flora of the Central Russia” (Vinogradova et al., 2010). Research was conducted during 2000–2009 in the territory of Bashkortostan Republic. Species invasion in the region and their naturalization on flood plains of the South Urals was noted (Abramova, Anufriyev, 2008; Abramova, 2014; Abramova, Nurmiyeva, 2014). In the centers of invasion of mentioned species 110 complete geobotanical descriptions of communities on trial platforms of 4–100 m² were executed. Classification of communities with the invasive species is carried out according to the Braun-Blanquet method with application of the deductive method (Kopečky, Hejny, 1974). The allocated syntaxa were compared to units earlier described in Bashkortostan Republic and other regions (Vegetace …, 2009; Yamalov et al., 2012; etc.).

Vegetation classification of Far North technogenic habitats (ground quarries, bulldozed areas, railway and road embankments) is done by the Braun-Blanquet approach. Plant communities were studied in 1993–2001 in following 5 regions (vicinity of Vorkuta, Novyi Urengoi, Norilsk and two stations of railway going to Yamal Peninsula) situated in forest-tundra and southern hypoarctic tundra. 7 new associations (Oxytropidetum sordidae, Tanacetetum bipinnati, Arctophilo fulvae-Eriophoretum scheuchzeri, Erysimo hieracifolii—Poetum alpinae, Polygonetum ochreati, Puccinellietum sibiricae, and Chamaenerio—Artemisietum vulgaris ass. prov.) including 4 subassociations, 36 variants and 56 subvariants were described. One community type (Puccinellia hauptiana—Descurainia sophioides) characterising the pioneer vegetation with plant communities of primary succession was described also. The distinguished syntaxa belong to the alliance Chamerio—Matricarion hookeri (Ishbirdin et al., 1996) Ishbirdin 2001. Taking into account the previous publication (Сумина, Копцева, 2004) the Far North technogenic habitat vegetation of this alliance is represented by 10 associations, 8 subassociations, 56 variants and 100 subvariants. Their complete prodromus is cited. The geographical and ecological positions of distinguished sytaxa are discussed.

The author believes that the vegetation classification is the classification of the samples, which are vegetation relevés. The properties of these samples, their sampling and manipulation influence the results of classification. Such vegetation relevés properties as completeness and quality of their floristic lists, size and shape of the plots are reviewed in the paper. An effect of the sampling process particularities on the classification in geographic space and time is discussed. Generally the sampling is carried out without maintaining firm parameters. One proposes to use more tight sampling standards to increase a degree of objectivity of vegetation classification. The author stresses that vegetation relevés have to be characterized by three space-time coordinates: geographical latitude and longitude, as well as realization time.

AbstractSymphyotrichum ciliatum was reported as invasive in Romania in the early 1970s. In this study we have analysed its invasion history, current distribution in Romania, habitat preferences and the associated plant communities. Data recorded during our recent field work, as well as from herbaria and previously published papers, were used in the analysis. This data confirms its invasive character. Given the abrupt increase in the slope of the invasion curve during the last decade, we can assume that S. ciliatum is still far from reaching the saturation phase of its invasion in Romania. Habitats invaded by this species are mostly anthropogenic herb stands associated with rail and road transport networks, and the continental inland salt steppes. The classical methodology of the Zürich- Montpellier school was used for the field phytosociological research and the classification of the investigated communities was done using the deductive method. The phytocoenoses dominated by S. ciliatum were classified as derivate communities. The description of these communities included data about plant composition, synecology and distribution in the study area.

The state of plant communities in areas located in the Tersko-Sulak lowland was studied by assessing phytocenotic indicators: the structure of vegetation cover, projective cover, species diversity, species abundance and elevated production, as well as automated decoding methods. There are almost no virgin soils and natural phytocenoses here; all of them have been transformed into agrocenoses (irrigated arable lands and hayfields, rice-trees and pastures). The long-term impact on pasture ecosystems of natural and anthropogenic factors leads to significant changes in the indigenous communities of this region. Phytocenoses are formed mainly by dry-steppe types of cereals with the participation of feather grass, forbs and ephemera, a semi-desert haloxerophytic shrub - Taurida wormwood. At the base of the grass stand is common coastal wormwood and Taurida wormwood - species resistant to anthropogenic influences. Anthropogenic impacts have led to a decrease in the number of species of feed-rich grain crops and a decrease in the overall productivity of pastures. Plant communities in all areas are littered with ruderal species. The seasonal dynamics of the land cover of the sites was estimated by the methods of automatic decoding of satellite images of the Landsat8 OLI series satellite for 2015, dated by the periods: spring - May 20, summer - July 23, autumn - October 20. Satellite imagery data obtained by Landsat satellite with a resolution in the multispectral image of 30 m per pixel, and in the panchromatic image - 10 m per pixel, which correspond to the requirements for satellite imagery to assess the dynamics of soil and vegetation cover. Lower resolution data, for example, NDVI MODIS, does not provide a reliable reflection of the state of soil and vegetation cover under arid conditions. In this regard, remote sensing data obtained from the Internet resource https://earthexplorer.usgs.gov/ was used.
