Tsitsin Main Botanical Garden of the Russian Academy of Sciences is subjected to significant anthropogenic stress, which has a negative effect on the state of valuable collections of tree and shrub species. Soil compaction is one of the most dangerous consequences of anthropogenic impact, expressed in increased recreational impact. In this context, the botanical garden was very concerned about the deterioration of the collection of elaeagnus species. Therefore, the soils on which these plants grow were chosen as the object of research. On this territory, three sampling plots with different degrees of anthropogenic impact were laid. Sampling plot No. 1 had the maximum anthropogenic impact. The area of medium anthropogenic impact was represented by the sampling plot No. 2. The sampling plot No. 3 where the anthropogenic impact was minimal was a reference plot. All the studied soils were classified as soddy-slightly podzolic medium loamy soils (Umbric Albeluvisols Abruptic). Fundamental differences in the morphological properties of the studied soils were that the soils located in the area of maximum anthropogenic impact, starting from a depth of 40 cm, showed gley spots, which were not found in other soils. Increased bulk density of soil in undisturbed state corresponded to increased anthropogenic impact. This led to a decrease in total pore space of soil. Soil compaction contributed to a noticeable decrease in gravimetric soil water content in upper horizons. At the same time, worsening of subsurface runoff contributed to gley-forming processes in the illuvial part of the profile. Cluster analysis revealed good grouping of the dependence of the studied indicators on the severity of anthropogenic impact. The studied indicators were separated depending on their type and position in the profile. The conducted study made it possible to assess the essential physical and hydrophysical properties of soils on the part of the territory of the Main Botanical garden of RAS that is occupied by the valuable collection of elaeagnus. Based on the results of the study, a set of measures is proposed that can significantly reduce the identified negative effects and improve the state of both the studied soils and stands growing on them in general. \u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\"><strong>Key<\/strong> <strong>words<\/strong><em>: bulk density of soil, anthropogenic compaction, soils of botanical gardens, GBS RAS<\/em><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">N.V. Tsitsin Main Botanical Garden of the Russian Academy of Sciences (GBS RAS) can be justly put on the list of the most interesting and well-known botanical gardens in the world. Opened in 1945, it compactly accommodates unique collections of tree and shrub species from all over the world (Demidov et al., 2016). By the decree of the Presidium of the USSR Academy of Sciences on December 2, 1991 the Main Botanical Garden was named after the member of the Academy of Sciences Nikolai Vasilievich Tsitsin.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">GBS RAS is the largest botanical garden in Europe. For the convenience of visitors and employees, the botanical garden has an extensive network of asphalt and dirt paths. Such a well-developed trail and path network allows for both easy hikes and active sports including running and cycling. High profile of the botanical garden among Muscovites and metropolitan visitors results into strong anthropogenic impact on its stands and soils (Grevtsova, Rysin, 2020).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The main issue with the soils of recreational areas is their compaction caused by heavy traffic of vehicles, people and animals. Soil compaction decreases the total pore space by 30\u201350%, primarily due to micropores, which play a central role in the movement of water and air as well as the spread and growth of plant roots. This directly affects the basic hydrophysical properties of the soil: on the one hand, water permeability decreases, and therefore conditions that favour water stagnation are created, which is best seen in illuvial horizons; on the other hand, the compaction of the upper humus horizon reduces the ability of soil to absorb and retain moisture. The negative impact of anthropogenic compaction on the crucial soil properties was reported by many researchers (Smagin et al., 2006; Lysikov, 2006, 2008, 2011; Yakovlev, Evdokimova, 2011; Melankholin, Lysikov, 2014; Stoma, 2016; Zakharov, Kulik, 2017; Murach\u0435va, 2018). It is usually not so much the over-compaction of soil on the paths as the preservation of unique park cenoses, where a variety of vegetation is represented, that causes concern (Mosina, 2003).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">It should be noted that some authors consider the soils of botanical gardens some kind of unique formation that differs from both natural and urban green areas and was formed due to constant introduction of soil fauna and microorganisms on plant roots and in soil as well as long-term (for decades and even centuries) anthropogenic (urbanogenic) impact (Rappoport et al., 2013). Thus, urban botanical gardens are unique artificially created ecosystems, where the negative impact of the urban environment is partially offset and there is a high level of biodiversity. This study was performed within that narrative, and the objective of the study was to identify and evaluate the likely impact of the complex of soil factors on the condition of stands (collection of elaeagnus species) of the GBS RAS.<\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\"><strong>MATERIALS AND METHODS<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">This research was carried out as part of a comprehensive soil and hydrotechnical survey of the territory of the GBS RAS conducted by the staff and students of Mytishchi branch of N.E. Bauman Moscow State Technical University. Special emphasis was made on looking into the influence of anthropogenic factors on soil properties, which, in turn, largely determine the conditions for the growth and development of tree and shrub species growing in the botanical garden (Rysin, Grevtsova, 2018). According to our tentative hypothesis, it was the anthropogenic compaction that could cause the death of the collection of <em>Elaeagnus<\/em>. Most likely, the paths made worsened the outflow of groundwater and led to soil waterlogging in the spring.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The study program included laying three sampling plots each 20\u00b420 m of size. Two sampling plots were located directly on the territory of the collection of elaeagnus. Sampling plot No. 1 was laid at a distance of about 10 meters from a busy central pedestrian walkway. This sampling plot represented the part of the territory occupied by the collection of elaeagnus with the highest anthropogenic impact. Stage 4 of recreational degradation was diagnosed for this area. Sampling plot No. 2 was located at a distance of about 20 meters from the central alley, next to a small path, where the anthropogenic impact was moderate. In this zone, recreational degradation was at stage 3. As a reference plot, sampling plot No. 3 was laid down in a relatively inaccessible place, where visitors to the garden do not get very often. The distance from the central pedestrian walkway was about 50 meters. Stage 2 of recreational degradation was stated in this area.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">During the field research phase, at each sampling plot 5\u20136 test pits were made. For each sampling plot, one most typical test pit was deepened to form a section. Thus, section B3 (N55.842984, E37.598317) was located in the area of maximum anthropogenic impact. The area with moderate anthropogenic impact was represented by section B2 (N55.84282, E37.59879), whereas the control section B1 (N55 N55.842588, E37.598169) was laid in the area with low anthropogenic impact. All locations are given in the WGS84 system.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">For the soil sections and pits, a complete morphological description was performed according to the methods used in soil science. Samples were taken from all sections on genetic horizons to determine the general physical and hydrophysical properties of soils at the soil laboratory of a department of Mytishchi branch of N.E. Bauman Moscow State Technical University. In particular, bulk density in the undisturbed natural state (according to N.A. Kachinski), field gravimetric soil water content by weight method and the total pore space of soil were determined. Assessment of soil parameters provided results within 5% in terms of accuracy of the experiment at a significance level of 0.05 (Vadyunina, Korchagina, 1986).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The selection of soil sampling points, georeferencing of the sections made, and land navigation were carried out using modern geoinformation systems. For the study, a combination of the NextGIS mobile application for Android and the Quantum GIS desktop application was chosen, the latter was used for combining and systematization of all the obtained geodata. The QGIS system has been an almost absolute leader in recent years in the free software class (Shokin, Potapov, 2015).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The obtained experimental data were processed using multidimensional statistical methods, more specifically, cluster analysis. For the studied objects, dendrograms were constructed, with the values of similarity (or difference) represented on the Y axis, and the numbers of objects with equal intervals represented on the X axis. The normalized Euclidean distance was chosen as a measure of difference: the geometric distance between objects in a multidimensional feature space. For clustering, Ward&#8217;s method was used. Analysis of variance method was used in this study to estimate distances between clusters. The distance between clusters is seen as the increase in the sum of squared distances from objects to the centre of the cluster, obtained as a result of their union.<\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\"><strong>RESULTS AND DISCUSSION<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Field studies showed that all the surveyed soils are Umbric Albeluvisols Abruptic (WRB, 2015). The grain size did not change significantly along the profile. Bigger grain size was found only in the lowest part of the profile in the transition horizons to the parent rock.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The main difference in the morphological properties of the studied soils was that in the soils located in the area of maximum anthropogenic impact, starting from a depth of 40 cm there were gley spots which were not found in soils with low and medium anthropogenic impact.

color: #000000;\">The lowest bulk density of soil in the undisturbed state is observed in the area of the minimum anthropogenic impact (Fig. 1). This trend is typical for the depth of the studied soil profile. Natural vegetation with a predominance of birch and mixed herbs in the ground cover at 0.97 g\/cm\u00b3 provided a fairly favourable density of the upper horizon \u0410\u2081. Density expectedly increases with the depth, reaching a maximum of 1.48 g\/cm\u00b3 in the B horizon. For the other two sections located in the area of strong anthropogenic impact, the density of the upper horizon \u0410\u2081 is substantially higher (1.29 g\/cm\u00b3 and 1.25 g\/cm\u00b3) near the walkway and the path, respectively. Although there is a walkway surfaced with good asphalt, some visitors still go off the paths, which leads to soil compaction, and the compacting effect reaches a considerable depth and is seen up to and including the illuvial horizon B.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Of course, these density values have a negative impact on both the state of the soil itself and vegetation, but for comparison, it should be noted that in similar studies, soil density figures in the middle of the path were up to 1.8 g\/cm\u00b3 (Lysikov, 2008, 2017). Thus, the regular network of well-maintained paths of the GBS still takes on the main load.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The above-mentioned increase in soil density in areas with high and medium anthropogenic impact leads to a decrease in its total pore space (Fig. 2), primarily due to the air pore space, but the capillary pore space also decreases.<\/span><\/p>\n<div id=\"attachment_4093\" style=\"width: 1010px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-4093\" loading=\"lazy\" class=\"size-full wp-image-4093\" src=\"https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/Pic-2.jpg\" alt=\"\" width=\"1000\" height=\"627\" srcset=\"https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/Pic-2.jpg 1000w, https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/Pic-2-300x188.jpg 300w, https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/Pic-2-150x94.jpg 150w, https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/Pic-2-768x482.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><p id=\"caption-attachment-4093\" class=\"wp-caption-text\"><span style=\"color: #000000; font-family: 'times new roman', times, serif;\"><strong>Figure 2.<\/strong> Changes in total pore space of soil depending on the anthropogenic impact<\/span><\/p><\/div>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Due to all this, field gravimetric soil water content of the compacted horizons decreases significantly (Fig. 3).

Zakharov (2107), who pointed out that in forested landscapes, paths are not an innocent element anymore, but a kind of <em>suffocating network<\/em> that breaks down the original woodland into increasingly isolated areas with pulsating and expanding patches of soil and vegetation cover degradation.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Increased loss of water from the upper horizon might also be facilitated by the forest live cover which suffers from trampling and therefore has lower species diversity and smaller projective cover than in the area not easily accessible for visitors.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Low water permeability negatively affects the growth and development of plants, increasing the risk of their death from drowning. Most likely, that very reason caused the death of the collection of elaeagnus on the territory of the N.V. Tsitsin GBS RAS. It could have been avoided by timely and appropriate reclamation measures.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">According to the cluster analysis, based on all the obtained soil indicators, areas with maximum and medium anthropogenic impact formed specific groups, whereas the territory with a low level of such impact could be separated quite early (Fig. 4).<\/span><\/p>\n<div id=\"attachment_4095\" style=\"width: 603px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-4095\" loading=\"lazy\" class=\"size-full wp-image-4095\" src=\"https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/ris4.png\" alt=\"\" width=\"593\" height=\"460\" srcset=\"https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/ris4.png 593w, https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/ris4-300x233.png 300w, https:\/\/jfsi.ru\/wp-content\/uploads\/2021\/03\/ris4-150x116.png 150w\" sizes=\"(max-width: 593px) 100vw, 593px\" \/><p id=\"caption-attachment-4095\" class=\"wp-caption-text\"><span style=\"color: #000000; font-family: 'times new roman', times, serif;\"><strong>Figure 4.<\/strong> Dendrogram of the studied objects (&#8220;Low&#8221; \u2013 low impact zone, &#8220;Med&#8221; \u2013 medium impact zone, &#8220;Max&#8221; \u2013 maximum impact zone)<\/span><\/p><\/div>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Thus, the changes in soil indicators allow us to state that even medium anthropogenic impact significantly affects the state of soil.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Fig. 5 shows the distribution of soil parameters (properties) in a multidimensional space.

Reconstruction of the roadway and addition of elements of selective closed material drainage to it can be recommended as first and most transformative measures to control moisture stagnation (caused by over-compaction and disturbance of the subsurface runoff). In areas of the most critical compaction, material or non-material air drainage should be used. Moreover, special emphasis should be made on controlling the flow of visitors using hedges and on the intensification of informational work with the botanical garden visitors.<\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\"><strong>CONCLUSION <\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The performed study made it possible to evaluate the most important physical and hydrophysical properties of soils of the part of the Main Botanical Garden RAS, occupied by the collection of elaeagnus and affected by anthropogenic impact of different intensity. A noticeable increase in the bulk density of soil in undisturbed state in the area of medium and maximum anthropogenic impact was found. Consistent with increased density, a decrease in the total pore space and gravimetric soil water content of the studied soils was observed. Cluster analysis showed that, in terms of the totality of the studied indicators, areas with maximum and medium anthropogenic impact are more similar to each other than to the area with low anthropogenic impact. Even the anthropogenic impact that is deemed medium significantly affects all of the most important general physical and hydrophysical properties of soils.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">The results of the study will form the basis for the development of detailed practical guidelines aimed at mitigation of the negative effects of human impact on soils of the GBS RAS and these findings will be included into the soil section of the integrated geographic information system of the GBS RAS and can then be used for assessment and monitoring of soils and plants in arboreta and enhance the recreational potential of the territory of the Botanical garden.<\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\"><strong>REFERENCES<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Demidov A.S., Rysin S.L., Kobyakov A.V., Vozmozhnosti ispol&#8217;zovaniya GIS-tehnologii v rabote botanicheskikh sadov (Possibilities of using GIS technologies in the work of Botanical gardens), <em>Lesokhozyaistvennaya informatsiya<\/em>, 2014, No. 4, \u0440\u0440. 68-72.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; color: #000000;\">Demidov A.S., Shustov M.V., Potapova S.A., Sokhranenie raznoobraziya rastitel&#8217;nogo mira Rossii v Glavnom botanicheskom sadu im.
