The determination ratio of timber tree in the composition of stands makes it possible to judge about geoecological state of the vegetation cover. It be noted heterogeneous studying of forests in different regions of the country, in connection with which the research of specially protected natural areas (SPNA), which includes the Dolinsky Nature Sanctuary, with an insufficient number of employees in the forest industry, becomes especially relevant. Automated decoding of remote sensing data serves as an aid to ground-based observations. Work to identify the species composition of forests according to aerospace surveys on the territory of Sakhalin Island previously carried out in small volumes. The Sentinel-2 satellite images of the territory of the Dolinsky Nature Sanctuary, obtained in 2018-2021, analyzed in order to identify the classification features of various plant communities characteristic of the southern part of Sakhalin. On basis of visual interpretation, reference sites for geobotanical studies were identified, which with a high degree of confidence attributed to specific plant formations: fir-spruce, stone-birch, willow-alder river valleys, bamboo, deforested areas and plantings of pine and larch crops. Further work carried out using the methods of geoinformation analysis in ArcGIS. The optimal combinations of channels in the formation of synthesized image composites for the selection of training samples for each plant formation were determined when performing vegetation classification. In case of difficulties with the separation of some formations (larch - pine) in the images, the work carried out based on the materials of multi-season surveys. The obtained characteristics of the training samples can be used for further research in the Dolinsky Nature Sanctuary and beyond.

First Time

The problem of protecting rare communities in the vegetation cover still remains poorly studied. Currently, it is relevant for aquatic and coastal aquatic plant communities of lakes and river estuaries of the Arkhangelsk Region. Two critical criteria were used to distinguish rare communities: 1) protected species are cenosis-formers, 2) species that were first noted outside the northern border of the ranges are either cenosis-formers, or abundant in the composition of communities. The first criterion includes communities with species listed in the Red Data Books of the Russian Federation (2008) and the Arkhangelsk Region (), if these species are significant from the point of phytocenosis. The last includes taxa and plant populations of the Arkhangelsk Region that need special attention to their state in the natural environment and are recommended for bio-surveillance. The second criterion includes the communities of the Glycerietum fluitantis association located on the coast of the Pechora Inlet, which were described here for the first time. The communities’ habitats are water bodies that differ significantly in hydrological conditions. Lobelietum dsortmannae, Isoëto lacustris–Lobelietum dortmannii, Isoëto echinosporae–Lobelietum dortmannae, Lobelieto dortmannae–Phragmitetum australis, Lobelieto dortmannae–Caricetum rostratae, Fontinalieto dalecarlicae–Phragmitetum australis, Fontinalieto dalecarlicae–Nupharetum lutea associations are typical for oligotrophic and oligo-mesotrophic lakes of the hydrocarbonate class with low water salinity. Nympheto candidae–Nupharetum pumilae, Potamogeneto natantis–Nymphaeetum tetragonae, Chareto virgatae–Scirpetum lacustris associations are identified in eutrophic and mesotrophic lakes. Communities of Chareto strigosae–Charetum asperae, Charetum subspinosae, Chareto subspinosae–Phragmitetum australis charosum subspinosae associations develop in sulfate lakes with increased water salinity. Ruppietum maritimae, Glycerietum fluitantis purum, Hippurideto tetraphillae–Glycerietum, and Zannichellia pedunculata communities are typical for river estuaries. We have described most of the rare communities for specially protected natural areas of the Arkhangelsk Region: in the Kenozero National Park, the Onega Pomorie National Park, the Pinezhskiy Nature Reserve, the Nenetskiy Nature Reserve, and the Pakhanchenskiy Nature Reserve. At the end of the article, some recommendations for the protection of rare communities are given. They are useful for monitoring such species in protected areas. The protection of rare communities is based on the principle that any species that is part of the community is its integral part. The destruction of cenosis-forming species leads to the disappearance of both an integral unique community and protected species as a part of it, regardless of whether they are phytocenotically significant, or grow singularly within the community.

В статье рассмотрены вопросы выделения малонарушенных природных территорий (лесных массивов) с учетом данных дистанционного зондирования земли. Для оценки малонарушенности площади соотносят с определенными критериями по площади массива, по возрасту основной части насаждений, по степени фрагментированности участка, наличия антропогенно нарушенных земель. Так, площади с хозяйственной деятельностью за последние 50 лет не допускаются более 5% от общей. Участки леса, которые планировали как малонарушенные лесные массивы (МЛН), по факту на 2018 год по данным космических снимков не всегда являлись таковыми. На примере двух из планируемых территорий после совмещения границ участков по планам лесонасаждений и космических снимков и выборки выделов по таксационным описаниям сделаны выводы о несоответствии одного из них критериям выделения малонарушенного лесного массива. Как показали космические снимки 2018 года и результаты анализа фактических характеристик лесонасаждений, часть лесных площадей к категории малонарушенных лесных массивов не относится. Только один из них, расположенный в Лахколамбинском участковом лесничестве, соответствует критериям для выделения его как МЛМ. Второй участок, расположенный в Куолисмском лесничестве, не соответствует критериям, предъявляемым к МЛМ по возрастному критерию и наличию здесь в последние 20 лет хозяйственной деятельности. Для участков, планируемых как малонарушенные лесные массивы, как и категории защитных лесов и особо охраняемые природные территории, следует учитывать ограничения по ведению хозяйственной деятельности, установленные действующим законодательством РФ. The article deals with the allocation of protected natural areas (forests), taking into account the data of remote sensing of the Earth. To assess whether the area is intact, it is correlated with certain criteria for the area of the massif, the age of the main part of the plantings, the degree of fragmentation of the site, and the presence of anthropogenic disturbed land. Thus, areas with economic activity over the past 50 years are not allowed to exceed 5% of the total. Areas of forest that were planned as intact woodlands (million), in fact, for 2018, according to satellite images, were not always such. For example, two of the planned territories after alignment parcel boundaries according to the plans of forests and satellite imagery and sampling areas for taxonomic descriptions of the conclusions about the discrepancy one of these criteria for identifying s old growth forest. As shown by the satellite images of 2018 and the results of the analysis of the actual characteristics of forest plantations, part of the forest area does not belong to the category of Not destroyed forests. Only one of them, located in the Lakhkolambin district forest area, meets the criteria for allocating it as an MLM. The second section, located in the Kuolismsa forest district, does not meet the criteria for Not destroyed forests based on age and the presence of economic activity here in the last 20 years. For areas that are planned as intact forests, as well as categories of protected forests and specially protected natural areas, it is necessary to take into account the restrictions on economic activity established by the current legislation of the Russian Federation.

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.

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 aeolian processes play an important role in the relief formation under the semiarid conditions of the intermountain basins of Southern Siberia. Ancient sand landforms occur in different regions of Siberia — the Ob, Chuya, Аley, Yenisei, Аngara, Selenga, Chikoy, Khilok and Chara river valleys and Lake Baikal coasts. The sandy coasts of Lake Baikal are of great interest in terms of floristic diversity determined by a high degree of endemism. Despite centuries of study of the lake basin, sand vegetation is poorly described in the literature. This study presents an analysis of 184 relevés of psammophytic vegetation from the Republic of Buryatia (Severobaikalsky, Barguzinsky, Pribaikalsky districts) and Irkutsk region (Olkhon Island) obtained in 2009–2014.

Tram Chim National Park in Southern Vietnam is a wetland area included in the system of specially protected natural areas (SPNA). For the purposes of land monitoring, we studied Landsat-5 and Sentinel-2B images obtained in 1991, 2006 and 2019. The methods of normalized difference vegetation index (NDVI) and water objects – normalized difference water index (NDWI) were used to estimate the vegetation in National Park. The allocated land is classifi ed by the maximum likelihood method in ENVI 5.3 into categories. For each image, a statistical analysis of the land after classifi cation was performed. Between 1991 and 2019, land changes occurred in about 57 % of the Tram Chim National Park total area. As a result, the wetland area has signifi cantly reduced there due to climate change. However, the area of Melaleuca forests in Tram Chim National Park has increased due to the effi ciency of reforestation in protected areas. Melaleuca forests are also being restored.
