Of these, 203 relevés were previously classified and published. In this paper based on 23 relevés two new associations and two new subassociations of the class Ammophiletea Br.-Bl. et Tx. ex Westhoff et al. 1946 and one rankless transitional community (Fig. 1) are described according to Braun-Blanquet approach. The abundance of plants estimated in the field as a percentage of the projective cover was converted to scale points: 5 — > 50 %, 4 — 26–50 %, 3 — 16–25 %, 2 — 6–15 %, 1 — 1–5 %, + — < 1 %. Clustering of the relevés (phytocenon isolation) was carried out by flexible beta linkage (β = –0.25) based on the Sørensen coefficient in PC-ORD 5.0, available through the JUICE 7.1 software package (Tichý, Jason, 2006). As a result four phytocenons were established. Their species composition was compared with the species lists of the lower 676 coastal syntaxa of the Azov-Black Sea region, taken from literature and stored in authors’ syntaxon database (GIVD ID EU-RU-005) based on the TURBOVEG program (Hennekens, Schaminée, 2001). An initial assessment of the similarity of littoral syntaxa and phytocenons was performed using several methods available in the JUICE 7.1 software package. In all cases bryophytes and lichens as well as vascular plant species with frequency less than 20 % in any community were excluded from the analysis. All these excluded species are present in Tables 1 and 2. To classify the established phytocenons, their species composition was compared with similar protologues of the lower syntaxa (Table 1). The vascular plant taxa names are by Tutin et al., (2001). In naming the taxa below, a broad understanding of species (s. l.), their aggregation (agg.), or the combination of several species (with “+”) are used: Artemisia campestris+A. tschernieviana, Cakile maritima s. l. (C. maritima, C. maritima subsp. euxina), Centaurea arenaria s. l.(C. arenaria, C. arenaria subsp. odessana), Leymus racemosus s. l. (L. racemosus, L. racemosus subsp. sabulosus); S. kali aggr. (Salsola kali, S. kali subsp. ruthenica or S. kali subsp. tragus) based on P. Uotila (2011) and S. L. Mosyakin (2017); Xanthium strumarium s. l. (X. strumarium, X. strumarium subsp. italicum, X. strumarium subsp. strumarium × subsp. italicum). Few bryophyte and lichen taxa are given with their authors. The names of the new syntaxa are formed according to the ICPN rules (Theurillat et al., 2021). The terrain in the study area is flat. The natural banks are represented by abrasion and accumulative types. The latter is often in the form of sandy or sandy-shelly spits. There are low-lying near-mouth and delta accumulative banks at the mouths of large rivers. Widespread are solonchaks both not vegetated or with halophytic communities.

From 2010 for 2021 the total area under crops in four regions (Leningrad, Novgorod, Pskov, Vologda) has decreased from 1150.7 to 907.5 thousand hectares. Studies of specific structure of weed communities of the North-West of the Russian Federation started in the first decade of the XX century with inspections of crops by A. I. Maltsev in the St. Petersburg region (Maltsev, 1908, 1909). Since the beginning of the XXI the study of weed plants were focused at the All-Russian Institute of Plant Protectionwhere monitoring of crops of the North-West of the Russian Federation (Mysnik, 2012; Luneva, Mysnik, 2016, 2017, Luneva et al., 2009) has became the priority direction. In spite of previous wide floristic researches, the diversity of weed communities of this region is still not established. The first results of the floristic classification of weed vegetation in the North-East of the Russian Federation are presented. The dataset is based on 278 relevés made by N. N. Luneva, I. N. Nadtochiy, E. V. Filippova, T. D. Sokolova, Yu. V. Eroshina for field seasons in 1999–2916. The research area covered Leningrad, Novgorod, Pskov and Vologda regions. Data processing was carried out according floristic classification approach (Westhoff, Maarel, 1978), using TWINSPAN algoritm in JUICE software packages (Tichy, 2002). The new syntaxa are named in accordance with the rules of the International Code of Phytosociological Nomenclature (Theurillat et al., 2021). DCA-ordination using the CANOCO 4.5 software package (Ter Braak, Smilauer, 2002) was produced to identify patterns of environmental differentiation. The habitat moisture and soil richness-salinity scales status of communities (Ramenskiy et al., 1956) was calculated and basic agroclimatic parameters were identified to characterize the ecological variability of habitats. The communities were classified within the order of Aperetalia spica-venti J. Tx. et Tx. in Malato-Beliz et al. 1960 of the class Papaveretea rhoeadis S. Brulo et al. 2001 and were assigned to the alliance Scleranthion annui (Kruseman et Vlieger 1939) Sissingh in Westhoff et al. 1946), which unites the most mesophytic weed communities distributed mainly on gray forest, sod-podzolic, podzolic and other types of soils of the forest zone. The alliance diagnostic species are Stellaria media, Tripleurospermum inodorum, Capsella bursa-pastoris, Lepidotheca suaveolens, Thlaspi arvense, Centaurea cyanus. Three species from the diagnostic groups of ruderal vegetation classes are also active in their cenoflora — Elytrigia repens, Viola arvensis, Taraxacum officinale. From the diagnostic group of the Papaveretea rhoeadis class and the order Aperetalia spica-venti with high constancy, species are found Cirsium setosum, Chenopodium album, Sonchus arvensis, less often are Fallopia convolvulus.

The synoptic table of dark coniferous forests syntaxa (Table) was developed and clarification of their diagnostic features was made. In accordance with the “Vegetation of Europe ….” (Mucina et al., 2016), the entire diversity of the higher units of the dark coniferous forests was classified into two classes, two orders and eight alliances. At the highest hierarchical level, two classes were clearly distinguished — the Asaro europaei–Abietetea sibiricae Ermakov et al. in Willner et al. 2016 and Vaccinio-Piceetea Br.-Bl. in Br. Bl. et al. 1939. The class Asaro europaei–Abietetea sibiricae includes subnemoral dark coniferous forests occurring in southern part of forest zone in the Southern Urals and Western Siberia. These forests combine some important features of boreal and nemoral vegetation in the phytocoenotic structure (physiognomy) and floristic composition. Therefore, the diagnosis of the class Asaro europaei–Abietetea sibiricae is based on a combination of the following criteria. 1. The absolute predominance of cold-resistant boreal tree species (Picea obovata, Pinus sibirica, Abies sibirica) in the higher layer makes it impossible to assign them to the higher units of nemoral vegetation and fundamentally distinguishes them from the class Carpino–Fagetea sylvaticae Jakucs ex Passarge 1968. 2. The high constancy values of widespread Eurasian shade-tolerant species associated dominantly with dark coniferous forests: Dryopteris expansa, D. carthusiana, D. assimilis, D. dilatata, Phegopteris connectilis, Diplazium sibiricum, Gymnocarpium dryopteris, G. robertianum, Athyrium filix-femina, Oxalis acetosella, widespread European-Siberian nemoral species: Daphne mezereum, Dryopteris filix-mas, Viburnum opulus, Stachys sylvatica, Galium odoratum, Geranium robertianum, Festuca altissima, Asarum europaeum, Actaea spicata, Brachypodium sylvaticum, Aegopodium podagraria, Viola mirabilis, Sanicula europaea, Festuca gigantea, as well as nemoral species with narrower ranges located in southern Siberia: Osmorhiza aristata, Anemonoides altaica, Corydalis bracteata, Erythronium sibiricum, Anemonoides caerulea, Myosotis krylovii, Euphorbia Pilosa and European species with eastern boundaries of ranges running in the southern Urals: Ulmus glabra, Pulmonaria obscura, Polygonatum multiflorum, Cicerbita uralensis, Geum urbanum, Carex pilosa, Euonymus verrucose. All these species were included in diagnostic combination of the Asaro europaei–Abietetea sibiricae. 4.

The data for the analysis was the base obtained in 2018–2021, including 312 relevés of psammophylous grass vegetation in the Southern Nechernozemye of Russia (Bryansk, Kaluga, south-west of Moscow, north-west of Oryol, Smolensk Regions). Most of the relevés were made on the watershed of two large river systems: the Dnieper (the Sozh river basin) and the Volga (the Oka river basin) while some ones are in the northwestern part of the Smolensk region (Demidovsky district, Smolenskoye Poozerye National Park), which belongs to the Zapadnaya Dvina basin. Natural psammophytic habitats in this region are widespread on outwash plains, sandy river terraces dominated by pine forests of the alliance Dicrano–Pinion sylvestris (Libb. 1933) W. Mat. 1962 nom. conserv. propos. Open sands are formed in the place of such forests after clear felling of pine with the destruction of the living land cover. In addition, psammophylous grass vegetation forms on non-flooded or short-flooded sandy ridges in river floodplains, on plowed sands that were opened during construction, along sand pits, on clearings under power lines, along old abandoned roads on sand embankments and sandy roads fallow lands and pastures with sandy and sandy loam soils (Kupreev et al., 2020). The psammophylous grass vegetation of the studied region is represented by 12 associations comprising 4 alliances and 2 orders of the class Koelerio–Corynephoretea canescentis Klika in Klika et Novák 1941, which unites dry grasslands on sandy soils and on rocky outcrops of the temperate to boreal zones of Europe, the North Atlantic islands and Greenland (Mucina et al., 2016). On the basis of comparative analysis for alliances and orders we compiled regional combinations of diagnostic species with constancy in coenoflora above 20 % and values of the statistical φ-coefficient above 20 (at p <0.01): Armerion elongatae (Armeria maritima, Astragalus arenarius, Dianthus fisheri, Jovibarba globifera, Jurinea cyanoides, Koeleria glauca), Corynephorion canesentis (Corynephorus canescens), Hyperico perforati–Scleranthion perennis (Berteroa incana, Festuca ovina, Helichrysum arenarium, Hypericum perforatum, Jasione montana, Pilosella officinarum, Rumex acetosella, Scleranthus perennis, Trifolium arvense).

The Conference was held September 26–30, 2022 in St. Petersburg (Proceedings…, 2022). 123 geobotanists from 25 cities of Russia participated in the Conference as well as our colleagues from Belarus, Kazakhstan, and Vietnam. The conference activity was held in three main topics: “Vegetation diversity and conservation”, “Structure and dynamics of plant communities”, “Vegetation geography and cartography”. At the plenary session and section meetings 62 oral and 56 poster presentations were presented. Three “round-table” talk sessions were held: two of them were dedicated to the problems of vegetation classification and the last — to the issues of geobotanical terminology. A significant part of the reports at the section “Diversity and protection of plant communities” was devoted to the classification of vegetation. The most part of authors used methods of floristic classification (Brown-Blanquet approach), but general analytic surveys were presented only in some works, and the rest were devoted to regional and local prodromuses of individual unions or to descriptions of lower syntaxa. A significant part of geobotanists follows the traditional principles of the Russian and Soviet school of dominant-determinant classification; the two other approaches to vegetation classification were applied in single reports: topological-ecological and geographical-genetic. Several papers have been devoted to the classification of habitat types. A significant part of vegetation studies have been carried out on the territory of protected areas: nature reserves, sanctuaries, national parks and natural landmarks: from the westernmost — Belovezhskaya Pushcha (Belarus) to the easternmost — the Bastak Reserve (Jewish Autonomous Region) and the Koryak Reserve (Kamchatka Region). Many of the reports at the section “Structure and dynamics of plant communities” concerned the study of vegetation dynamics after anthropogenic impacts, which are the main destabilizing factors of vegetation cover. Very few studies related to climate change have been presented. Several reports analyzed the demographic structure of populations. Few reports were also devoted to the statistical modelling of vegetation dynamics. The modern approach based on the functional characteristics of plants is just beginning to develop in Russian geobotany. Rapidly developing machine learning methods are gradually being introduced into the arsenal of geobotanical science methods — for the purposes of vegetation classification and vegetation mapping.

This paper presents the classification results for the low-sedge vegetation of waterlogged hollows and Sphagnum lawns, within flat palsa-bogs, ombrotrophic raised bogs and transitional mire complexes, which is assigned to two alliances — Stygio–Caricion limosae Nordhagen 1943 and Scheuchzerion palustris Nordhagen ex Tx. 1937 of the class Scheuchzerio–Caricetea nigrae Tx. 1937. The classification is based on 422 relevés performed in 2004–2019 at 22 plots located between 63° and 75° N in the northern taiga, forest tundra, and southern tundra subzones of West Siberia (Fig. 1). In the most recent summary “Vegetation of Europe…” (Mucina et. al., 2016), the alliance Stygio–Caricion limosae is assigned to the order Sphagno watnstorfii–Tomentypnetalia Lapshina 2010, however this does not seem conclusive. Communities of this order are closely associated with rich fens, often spring fens fed by ground water, which does not correspond to the real conditions in which communities of this alliance are developed. Ecologically, in the current structure of the class Scheuchzetio–Caricetea nigrae (Peterka et al, 2017), the alliance Stygio–Caricion limosae has taken the true place of the alliance Rhynchosporion albae Koch 1926 (ICPN, Art. 36), which was initially unambiguously associated with the order Caricetalia nigrae Koch 1926 based on the original relevés and diagnostic species (Rhynchspora alba, Agrostis canina, sphagnum mosses of sec. Subsecunda). Therefore, we also consider the alliance Stygio–Caricion limosae belonging to the order Caricetalia nigrae, where it fits better judging by its ecological and floristic features. The differential species combination of the alliance Stygio–Caricion limosae in the northern part of West Siberia includes Carex limosa, Drosera obovata, Juncus stygius, Gymnocolea inflata, Sphagnum perfoliatum, S. platyphyllum, S. subsecundum, Utricularia minor, U. ochroleuca, Warnstorfia exannulata, and W. fluitans. Within this alliance, two new associations with subassociations have been described: Utricularo ochroleucae–Caricetum limosae and Sphagno perfoliati–Caricetum rotundatae, of which the first one occurs in the northern taiga mires, while the second one in the forest tundra and southern tundra subzones. The order Scheuchzerietalia palustris Nordhagen ex Tx. 1937 comprises ombrotrophic vegetation of Sphagnum lawns and bog hollows (Mucina et al., 2016) and currently includes the only alliance Scheuchzerion palustris.

The subassociation F. e.–Q. r. typicum Bulokhov et Solomeshch 2003 in Bulokhov et Semenishchenkov 2015 unites communities occurring mainly in the broad-leaved forests zone of the Central Russian Upland. The subassociation F. e.–Q. r. stellarietosum nemori Semenishchenkov et al. 2015 occurs in the northern part of the association range in the zone of broad-leaved forests and close to the southeastern border of the hemiboreal subzone. Mesophilous broad-leaved forests occurring in the forest-steppe zone of the Central Russian Upland were included in the subass. F. e.–Q. r. crataegetosum curvisepalae Semenishchenkov in Bulokhov et Semenishchenkov 2015. The geographical distribution of the syntaxa is related to the climate continentality gradient — from the subass F. e.–Q. r. crataegetosum curvisepalae (the largest continentality indices) to the subass. F. e.–Q. r. stellarietosum nemori (the smallest continentality indices). The associations Aceri campestris–Tilietum cordatae Zaugolnova et Braslavskaya 2003 (nom. inv.) from the Kaluga and Tula Regions (Zaugolnova, Braslavskaya, 2003) and Aceri campestris–Quercetum roboris (nom. inv.) (var. Acer tataricum) described from the Voronezh Region (Starodubtseva, Khanina, 2009) were included in the association Fraxino excelsioris–Quercetum roboris after comparative syntxonomical analysis. On the basis of a comparative analysis, diagnostic combinations of subassociations were compiled, consisting of species with constancy above 20 % and values of the statistical φ-coefficient for selections above 20: F. e.–Q. r. stellarietosum nemori — Carex sylvatica (5059.9), Equisetum hyemale (2842.3), Galeobdolon luteum (10087.4), Matteucia struthiopteris (4257.7), Ranunculus cassubicus (5857.9), Stellaria nemorum (3349.6); F. e.–Q. r. crataegetosum curvisepalae — Acer tataricum (5362.0), Crataegus rhipidophylla (5964.0), Poa nemoralis (2736.9), Pyrus pyraster (3840.8), Scilla siberica (4558.4), Viola odorata (3440.5). Analysis of the differentiaal table of mesophilous broad-leaved and spruce-broad-leaved forests syntaxa made it possible to conclude that associations previously (Onyshchenko, 2009) assigned in Ukraine to alliance Scillo sibericae–Quercion roboris have a high floristic similarity with the syntaxa of Aceri campestris–Quercion roboris from the South-West of Russia, especially in the forest-steppe part of its range.

Holub is a rare species that grows in Yakuyia in lakes and reservoirs of deltaic systems of the large rivers (Lena, Kolyma, Yana, Indigirka, Anabar) mainly north of 68° N(Bobrov, Mochalova, 2014, 2017; Egorova, 2016; Opredelitel’…, 2020). The species is listed for Taymyr Peninsula as the most common in the plain part of the southern tundra and in the forest tundra (Pospelova, Pospelov, 2007) and as rarer in the typical tundra (Polozova, Tikhomirov, 1971). In general, this is a rather rare species. Besides the Taymyr Peninsula and Yakutia it occurs in the Bolshezemelskaya tundra, in the mouth of the Yenisey River, in Chukotka Peninsula and Alaska (Yurtsev et al., 2010; Bobrov et al., 2021). Stuckenia subretusa is a critical taxon associated by some authors (Kaplan, 2008; Konspekt…, 2012) with S. vaginata (Turcz.) Holub. However, both morphological and molecular genetic differences between these taxa were shown later (Volkova et al., 2017). It was also shown that S. subretusa is found in the lower reaches and estuarine areas of the large rivers in Asia, mainly north of 68° N, in Europe — of 67°, while the northern limit of the distribution of S. vaginata in Yakutia — 64°, in Europe — 66° (Bobrov, Mochalova, 2014), therefore these species are geographically separated. In July 2021, during a geobotanical survey of the islands of the southern part of the Lena River delta, thickets of S. subretusa were found on Sasyl-Ary Isl. (Fig. 1) in a shallow flow (channel) of 2 km total length, 130–150 m width and from 4–5 cm to 1.5 m depth with a very sluggish current. The bottom substrate is silty sands. Permafrost is 2–3 m depth. Thickets of S. subretusa were found only at 4–30 cm water depths. The thickets are monospecies with projective cover from 35 to 80 % (Fig. 2). Single specimens of Tephroseris palustris (L.) Rchb. were met rarely, at 4–5 cm water depths. Part of the thickets was located on wet sand along the shallows of the channel. S. subretusa was not found on neighboring islands. Five geobotanical relevés were made within the flow according to the generally accepted methodology with georeferencing using 12-channel GPS in the WGS-84 coordinate system on sample plots of 10×10 m. The classification was carried out on the principles of the ecological-floristic approach (Westhoff, van der Maarel, 1973). Estimation of the species projective cover in Table is given according to the Brown-Blanquet scale (Becking, 1957): r — single; + — less than 1 %; 1 — 1–5 %; 2 — 6–25 %; 3 — 26–50 %; 4 — 51–75 %; 5 — 76–100 %. The syntaxon name is given in accordance with the International Code of Phytosociological Nomenclature (Theurillat et al., 2021). The described communities belong to the class Potamogetonetea Klika in Klika et Novák 1941, the order Potamogetonetalia Koch 1926, and the alliance Potamogetonion Libbert 1931. We consider these as a part of a new association. The ass.
