The paper presents the results of vegetation studies in the Zaisan depression. The middle-scale vegetation map (s. 1 : 500 000) was created. Dominant species of vegetation cover form several ecological-physiognomic vegetation types: psammophytic shrub, psammophytic wormwood, psammophytic grass, perennial saltwort, sagebrush, shrub, saxaul, sagebrush – bunch grass, coniferous forest; floodplain meadow, shrub and woody are characteristic types of river valleys. These types are represented in the map legend. Analysis of the ecological preferences of the dominant species of Zaisan depression revealed the edaphic amplitude of plant species. A large part of dwarf semishrubs (sagebrushes and perennial saltworts) is characterized by wide edaphic amplitude. Shrub Spiraea hypericifolia has also a wide edaphic range. Stipa sareptana is the most ecologically labile species among bunch grasses. Zaisan saxaul is mainly grows on brown and gray-brown soils. The legend to the map is compiled on the base of zonal-typological principle, it contains 35 numbers. 8 numbers of the legend show the homogeneous vegetation, 27 – heterogeneous vegetation. Zonal types of vegetation occupy 64% of the territory (deserts – 32.4%, steppes – 31.6%); intrazonal vegetation – 23.6%. About 17% of the territory is agricultural lands, mostly located in the steppe zone.

The fragment of the legend of the map concerning the vegetation of flood- plains and river-valleys in the subzones of northern and southern deserts is presented in the article. The map is compiled in Department of Vegetspon Geography and Cartography of Komarov Botanical Institute by a large team of botanists-geographers of the former USSR. The nature environments determining the development of vegetation of river-valleys in arid climate are conditioned by the intrazonal factors (alluvial and flood processes) at the background of natural zonal factors. Contrasts of environments and corresponding plant communities manifest themselves first of all. Mineralization of ground waters, salinity of soils, including the alluvial ones, are of essential importance. The practice of vegetation mapping of unstable habitats, to which floodplain landscapes belong, has shown that units of phytocoenological classification is of little use for this purpose. The heterogeneity of vegetation, consisting of short-term unstable serial communities generates a need for typification of space combinations of such phytocoenoses. For this purpose it is convenient to use generalized ecological-dinamic series, including plant communities of all levels within the limits of definite segment of valley. These series are the mapping units on the map. The vegetation of the first terrace is also nessecary to include in a single series with flood-plain vegetation because it has supplementary influence of ground waters. The higher divisions of the legend are based on zonal characters: vegetation of valleys in northern, middle and southern deserts. 13 numbers are used to show the vegetation cover of flood-plains and valleys. Additional 7 numbers are used for the out-of-valley meadow vegetation. The content is enriched by using of the letters by the numbers showing the geographic variants of series and ciphers for combination of series and out-of-series communities. The text legend is supplemented by the matrix (table), showing the subordination of subtitles, zonal position and geographic distribution of divisions. The types of series in the matrix are listed with indication of the main dominant species that gives the additional information on the legend divisions. The author's conclusion is that valley vegetation reveals clearly the zonal features, correlating with zonal (desert) vegetation.

The standard sample area of 50 km2 for large-scale vegetation mapping has been taken on the water-shad of Bagan and Karasu rivers. Relief of the region is formed byelongate hills («griva») and depressions between them. The hills are occupied by arable land whereas the depressions are covered by natural vegetation. The main reguliarities of vegetation cover are presented on the vegetation map at 1 : 100 000 scale (fig. 1). 25 of the 31 numbers of the legend represent heterogeneous vegetation; these are territorial units, combinations sensu S. A. Gribova and T. I. Isachenko (1972) or phytocoenochoras after V. B. Sochava (1979). All the heterogeneous territorial units are subdivided into two categories – microcombinations and mezo-combinations. While the formers include complexes and microzonal series, the latters include ecological series and combinations. The inner diversity of territorial units is reflected in more details on the key plot of 100 x 100 m showing the vegetation of a small interhill depression with salt-rich soils. Through the comparison of different scale schematic pictures – 1 : 1000 (fig. 2a), 1 : 10 000 (fig. 2б), 1 : 50 000 (fig. 2в) – the process of generalization of territorial unit structures is illustrated, starting from the complexes, proceeding to microzonal series and, finally, to mezocombinations. The main territorial unit for large-scale and middle-scale maps is mezocombinations.

The North-Eastern Altai is an ultra-humid area with climax vegetation represented by tall-herb fir (Abies sibirica) dark-coniferous forest. Its meadows belong to the class Molinio-Arrhenatheretea. The typical asso­ciation Aegopodio podagrariae—Dactyletum glomeratae originates in the watershed clearings after climax forests whereas ass. Hyperici perforati—Agrostietum giganteaereplaces the previous one under mowing and grazing. The Molinietalia wet meadows are widespread in the river valleys. The meadows of ass. Cirsio heterophylli—Calama­grostietum langsdorffii occur on wet soils in small depressions and along floodplain mire margins, and ass. Ca­rici ovalis—Deschampsietum cespitosae comprises typical floodplain hay-meadows on moist, nutrient-rich soils.

Geobotanical mapping of the territory in riverheads Bureya of 4500 sq.km is carried out and the map of a actual vegetation cover of scale 1 : 200 000 is prepared. The legend of the map is presented in the form of the text with three-level hierarchy of classes. At the heart of structure of a legend of the map such regularities of a vegetation cover, as its latitudinal zonality / altitudinal belts, situation in a relief and dynamic series lie. The largest divisions of the legend reflect, first, change of large classes of mesocombinations of vegetation at the level of belts and, secondly, distinction in a boreal - forestry belt between a vegetation cover of tops and slopes of mountains, on the one hand, and the bottoms of river valleys, with another. Divisions of the legend of the second level reflect, first, vegetation changes in the form of high-rise and barrier changes of subbelts, secondly, distinctions of a vegetation cover in different geomorphological conditions (small and average river valleys, northern slopes, etc.). Divisions of the legend of the second level correspond to dynamic series of units of the third level. Essential addition to it are block diagrams of dynamics of a vegetation cover.

Two territories on the western coast of Peter the Great Bay were mapped in the large scale. The geobotanical mapping means revealing and displaying the essential regularities of vegetation cover. Both the spatial and temporal regularities of vegetation under natural and anthropogenic influences are well pronounced in the territory under consideration. The concept of the vegetation spatial unit (vegetation complexes) was applied as a basis for mapping. The maps and their legend were worked out as a system of vegetation combination types (vegetation combination is a spatial unit of the supracoenotic level). Such categories, as vegetation of tops and slopes, lowlands and river valleys, sea coasts reflect maximal contrasts in vegetation cover, so they are the highest level divisions of the map legend. Types of succession series and stages of series are developed for construction of the second and third levels of the legend. Communities, similar in ecotope, total species composition, saplings and some other characteristics, are referred to one type of series. 5 types of series have been distinguished: dry, fresh, moist, very moist, wet. The main factor of dynamics in considered territory is fire and the series are mainly pyrogeneous. Series are presented as sequences of vegetation stages. The vegetation stages for tops and slopes are: closed low forest — open low woodland — shrub thicket with saplings — meadow with saplings, for lowlands and river valleys they are: open low woodland — thicket of saplings — meadow or mire with saplings.

The study of the nature reserve oak forest near the village of Pelya-Khovanskaya ecosystem was done in the region of Nizhny Novgorod. The investigated wood is unique for its complex structure. It is situated in the forest-steppe zone, characterized by a high species diversity of small mammals and vegetation, which indicates the complexity of trophic and spatial connections. Several series of sample plots were described: 41 of 2020 m and a number of 11 m sites, totaling 300. Abundance of species by Brown-Blanke scale and the number of specimens of adolescence were specified for each 1 sq. m. plot. Mammals were trapped with the help of trapping grooves and transects method. Vegetation cover is characterized by the presence of a clear intra-differentiation as well as the existence of two basic ecologo-coenotic groups/cores - the nemoral (with Pulmonaria obscura Dum. as the center species of the core) and the meadow-fringe. The most distinct group is formed by forest-shoot species. It can be explained by more forest-steppe rather than nemoral nature of vegetation. Small mammals are represented by the following species: common and small shrews, small forest mouse, yellow-throated and field mice and harvest mouse, vole-housekeeper, common, plowed and red voles, European mole. Two species among them - vole-housekeeper and mouse-baby - are listed in the Red Book of the Nizhny Novgorod Region. Matching burrows of mouse-like rodents with soil richness with nitrogen and humidity, two well-defined peaks are observed. The greatest number of burrows is found in places where the soil is high in nitrogen. Moles were found in areas with a large projective coating of Primula veris: coefficient Spearman rank 0,50. There was a negative correlation of the number of moles and vegetation covering of Pyrethrum corymbosum (-0,46), which is the marker of the driest parts in the forest. In general, the nature reserve oak forest near the village of Pelya-Khovanskaya is of considerable interest, both from botanical and from zoological point of view. Long-term studies of biocoenosis will allow to monitor the facility and to correct the proposed protective measures.

A study of the flora and vegetation physiognomy was conducted at the core zones of the Monarch Butterfly Biosphere Reserve, in the states of México and Michoacán. Collection of plant specimens was carried out du ring one year of field work and this activity was supplemented by a review of voucher specimens previously collected in the area and deposited at the Mexican herbaria IEB, EBUM, and MEXU. A total of 423 vascular plant species including 32 infraespecific taxa and grouped in 86 families and 244 genera were identified, Families with the largest species richness were Asteraceae (103), Lamiaceae (21), Fabaceae (17), and Scrophulariaceae (17).The most speciose genera were Salvia (13), Stevia (8), and Ageratina (7). Mexican endemic species comprised 135 (31.9%) species, which included 13 infrae spec ific taxa; 40 of these species belong to Asteraceae. Herbs were represented by 326 species, followed by shrubs (5 1) and trees (33). The main vegetation types recognized were coniferous forest (including combinations of fir, pine, and oak forests), cloud forest, anthropogenic grass land, and Quercus forest.

The research is devoted to the study of poorly preserved psammophytic variants of meadow steppes in the forest-steppe zone of the Middle Volga Region. It has allowed to define the main stages of re-establishment of vegetational cover and estimate the conservation prospects on the river Ardym in different ecological conditions (geomorphological and edaphyc). It has been established that the re-establishment of psammophytic steppes vegetation occurs in a similar way both on the slopes of the predominantly southern exposition and on watershed surfaces. However, in the absence of anthropogenic effects on watershed surfaces, there is a sylvatization of the vegetation cover resulting in displacement of psammophytic steppes. Only the constantly occurring weak natural erosion processes on the slopes of the predominantly southern exposition contribute to the preservation of these rare communities here. Under intense anthropogenic influence, as well as in the conditions of a significant erosion process, the psammophytic steppes fail to be preserved or replaced by steppe meadows.

The study covered 10 small rivers in the North-Eastern part of the Samara Volga region. The author studied the vegetation cover, which is understood as a set of phytocoenoses and their constituent plant species. On the territory of Pokhvistnevsky District, there are two groups of river valleys that are heterogeneous in geobotanical terms. The first group includes the rivers with forested valleys (Kutlugush, Murakla, Karmalka). Their slopes are more or less symmetrical and steep. The vegetation cover of an undeveloped floodplain is usually uniform, and there is usually no belt. The valleys of the second group are treeless; their slopes are sharply asymmetrical (Amanak, Tergala, Talkish). The right-bank tributary of the Maly Kinel River the Lozovka River with its length of 20 km and the left tributary Kuvayka River with its length of 16 km were studied on the territory of Kinel-Cherkassky District. The Padovka and Zaprudka rivers and the right tributaries of the Bolshoi Kinel River (Kinelsky District) were also studied. The most common associations are (Salix fragilis heteroherbosa, Scirpus sylvaticus purum, Agrostis stolonifera Amoria repens, Elytrigia repens + Poa angustifolia heteroherbosa). In total, 19 types of phytocoenoses were noted, 4 of them are found in half of the studied rivers. In the plant communities of small river valleys there are 232 species of higher wild plants, which belong to 139 genera from 48 families. This is 60% of the total number of higher plants registered in the flora of small river valleys of the Samara Region. Rare protected plant species are registered here: Adonis volgensis Steven ex DC., Cacalia hastata L., Delphinium cuneatum Stev. ex DC., Globularia punctata Lapeyr.
