Аннотация: Parameters of reproduction of the Siberian stone pine (Pinus sibirica), including radial and apical tree increments, the age structure of stands, the amount of young growth, and its distribution along an altitudinal gradient, have been studied in the forest-tundra ecotone of the Western Sayan. The results show that, over the past 30 years, P. sibirica undergrowth has expanded to the mountain tundra belt, the apical and radial tree increments and stand density have increased, and the life form of many P. sibirica plants has changed from prostrate to erect (single-or multistemmed). These changes correlate with the dynamics of summer temperatures and monthly (in May and June) and annual precipitation. The rise of summer temperatures by 1 degrees C promotes the expansion of P. sibirica undergrowth for approximately 150 m up the altitudinal gradient.

Аннотация: The expansion of so-called evergreen conifers (EGCs), including Siberian stone pine, spruce, and fir, along the transect oriented from the boundary of the larch-dominated zone (LDZ; mixed forests of the Yenisei Ridge) to its center has been studied. The normalized dispersal coefficient calculated as K-i = (n(i) - N-i)/(n(i) + N-i), where ni and Ni are the relative numbers of the ith species in the undergrowth and the upper layer, respectively, serves as an indicator of the expansion. It has been found that the Ki values for EGCs (and birch) are higher than the Ki of larch even in the zone absolutely dominated by larch, where the relative numbers of EGCs in the upper layer is less than 1%. The EGC undergrowth has mainly been formed during the past 20-30 years, which is correlated with the trend of summer temperatures The spread of EGCs in the LDZ depends on the frequency of forest fires. The decrease in the time intervals between fires in the 20th century to 65 years (versus 100 years in the 19th century) may have prevented the expansion of competing species in the LDZ. The results obtained indicate that EGCs and birch penetrate into the zone traditionally dominated by larch, which is related to climatic changes during the past three decades. At the same time, tree stand density is increasing in the forest-tundra ecotone, and larch is spreading further into the tundra zone.

Аннотация: Climate-related changes that occurred in the Ary-Mas larch forests (the world's northernmost forest range) in the last three decades of the 20th century have been analyzed. An analysis of remote-sensing images made by Landsat satellites in 1973 and 2000 has provided evidence for an increase in the closeness of larch forest canopy (by 65%) and the expansion of larch to the tundra (for 3-10 in per year) and to areas relatively poorly protected from wind due to topographic features (elevation, azimuth, and slope). It has also been shown that the radial tree increment correlates with summer temperatures (r = 0.65, tau = 0.39) and the amounts of precipitation in summer (r = -0.51, tau = 0-41) and winter (r = -0.70, tau = -0.48), decreases with an increase in the closeness of forest canopy (r = -0.52, p > 0.8; tau = -0.48, p > 0.95), and increases with an increase in the depth of soil thawing (r = 0.63, p > 0.9; tau = 0.46, p > 0.9). The density of undergrowth depends on temperatures in winter(tau = 0.53, p > 0.8) and summer (r = 0.98, p > 0.99, tau = 0.9, p > 0.99) and the date of the onset of the growing period (r = -0.60, p > 0.99; T = -0.4, p > 0.99) and negatively correlates with the amount of precipitation in summer (r = -0.56, p > 0.99, T = -0.38, p > 0.99).

Аннотация: На основании анализа литературных источников и материалов собственных исследований рассмотрена экологическая обстановка на п-ове Таймыр в связи с аэротехногенным воздействием Норильского горно-металлургического комбината (НГМК). Дана оценка динамики состояния лесов за последние десятилетия в полосе от непосредственной близости до 200 км и более от комбината. Анализ проведен с учетом ландшафтной структуры территории. Отмечено прогрессирующее с начала 80-х гг. усыхание больших массивов лесов. По литературным данным приводятся структура, динамика и распределение аэропромвыбросов предприятий Норильской горно-металлургической компании «Норильский никель», а по данным авторов рассматривается воздействие аэропромвыбросов Норильского промышленного района на лесные экосистемы Таймыра. Основное внимание уделено главной лесообразующей древесной породе - лиственнице сибирской Larix sibirica Ledeb. Отмечено полное отсутствие подроста лиственницы в зоне промышленного загрязнения. Изучение состояния техногенно поврежденных лесов проведено на основании дендрохронологических исследований в шести различных точках на разном расстоянии от г. Норильска, в основном южнее и восточнее металлургического комбината. Одна точка исследований (разреженное лиственничное сообщество) находится в 5 км северо-западнее Норильска. Исследовали насаждения разной степени поврежденности, в том числе полностью погибшие. Показано, что вне зоны влияния эмиссий НГМК не отмечено признаков повреждения листового аппарата деревьев, тогда как в зоне атмосферного загрязнения (оз. Хантайское) древостой в значительной степени пострадал. Главным повреждающим агентом служит двуокись серы.
In the study, based on the analysis of literary sources and the own research materials, the characteristic of the environmental situation in Taimyr is done, in connection with aerial technogenic impact of the Norilsk mining and metallurgical industrial complex. The dynamics of forest condition over the past decade in the area close to 200 km or more from the plant were evaluated. The analysis was performed taking into account the landscape structure of the territory. The progressive drying of the large areas of the northern forests since the early 80 is registered. In the article, according to the literature reviewed, the structure, dynamics and distribution of air industrial emissions of the Norilsk mining and metallurgical industrial complex «Norilsk Nickel» is analyzed and presented. Further, the authors considered the impact of air industrial emissions of Norilsk industrial region on the forest ecosystems of Taimyr. The focus is on the main forest-forming tree - Siberian larch Larix sibirica Ledeb. It is noted the complete absence of the larch undergrowth in the area of industrial pollution. Investigation of the technogenically damaged forests was carried out on the basis of dendrochronological research at six different points on different distances from the city of Norilsk, mainly to the south and east of the metallurgical plant. One study point (sparse larch community) is located 5 km north-west of Norilsk. We investigated stands of varying degrees of damage, including completely dead. It is shown, that outside the area of Norilsk mining and metallurgical industrial complex impact there were no signs of damage to the foliage of the trees and on the contrary, in the area of air pollution (Khantaiskoe Lake), forest stands are largely affected. The main damaging agent is sulfur dioxide.

Аннотация: We tested management practices to develop Siberian pine forests at monitoring plots of the Institute of forest in Ermakovo (Western Sayan). Siberian pine forests developed from mixed young stands. They grew on clearcuts in tall grasses-ferns fir and Siberian pine forests in submontane dark taiga domain. The dynamics of all storeys and structural elements of the communities were studied and compared to the control at two 2500 m2 plots from 1966 to 2014. Here we consider the case of admitting light to the Siberian pine undergrowth at first thinning. This practice has proved itself optimal for further management recommendations. Siberian pine trees have gained competitive advantage in aspen or fir forests after the first thinning for a short period before the dominant species or birch started to regenerate actively. Repeated thinning supported sustainable dominance of Siberian pine in the stands. Our experiment showed that highly productive Siberian pine forests in the unique environment could be formed for 50 years rather than more than 200 years of natural succession. The managed stands and intact Siberian pine forests in dark taiga have similar normality of 0.4-0.6 and storages of 182 m3 ha-1 at the age of 70-80 years and 270 m3 ha-1 at the age of 80-90 years. However the managed stands yield more nuts (about 300 kg ha-1) at the age of 70-90 years. Thinning supported the growth of the stand with dominant Siberian pine, and phytocoenotic structure similar to intact Siberian pine forests of dark taiga having high diversity, which supports regeneration of Siberian pine. © 2017, Izdatel'stvo Nauka.

Аннотация: We have tested management practices at monitoring plots of the Institute of Forest, Russian Academy of Sciences, in Ermakovo station (Western Sayan) to develop Siberian pine forests (Pinus sibirica Du Tour) from young coniferous-deciduous forests that were formed in the place of clearcuttings in tall-grass-fern fir and Siberian pine forests in the low-mountain dark Chern zone. The dynamics of all layers and structural elements of the communities were studied from 1966 to 2014 at two experimental monitoring plots (each with an area of 2500 m(2)) and compared to the control. The article considers the case of admitting the complete lighting of Siberian pine undergrowth at first thinning. This practice proved to be optimal for further forest-management recommendations. Siberian pine gained competitive advantages over aspen or fir after the first thinning for a short period until the dominant species (aspen, birch, or fir) started to actively regenerate. Repeated thinning made Siberian pine steadily dominant in stands. Our experiment has shown that highly productive Siberian pine forests can be formed for 50 years under the unique natural and climate conditions of the low-mountain Chern zone of the Western Sayan, while the natural course of succession could not yield this result even after 200 or more years. These forests are comparable to indigenous dark Siberian pine forests with respect to their density (0.4-0.6) and wood stock (182 m(3)/ha at the age of 70-80 years and 270 m(3)/ha at the age of 80-90 years); however, the managed stands yield many more nuts (about 300 kg/ha) at the age of 70-90 years. Thinning induced the growth of a stand dominated by Siberian pine, as well as the formation of a phytocenotic structure similar to indigenous dark Siberian pine forests, i.e., a structure with a high diversity.

Аннотация: Изучена динамика микробной биомассы, ее структура и функциональная активность в почвах вырубок пихтарников южной тайги Енисейского кряжа (Красноярский край), находящихся на разных стадиях естественных восстановительных сукцессий растительности. В верхних органо-минеральных горизонтах дерново-подзолистой почвы (Albic Glossic Retisol (Loamic, Cutanic, Ochric)) сукцессионной серии вырубок, восстанавливающихся через смену пихтарников на производные березняки, выявлен рост содержания углерода микробной биомассы (Смик) и интенсивности базального дыхания от свежей вырубки к стадии лиственного жердняка, в профиле которого наиболее высокие общие запасы Смик (170 г С/м3) и микробная продукция СО2 (528 мг СО2–С/(м3 ч)), превышающие контроль на 80–85%. В гумусово-аккумулятивном горизонте названного ряда вырубок отмечена тенденция снижения как доли грибного субстрат-индуцированного дыхания, так и отношения грибы/бактерии по сравнению с контролем. В средневозрастных лиственных насаждениях с темнохвойным подростом все рассматриваемые параметры микробных комплексов снижаются, но продолжают превышать контроль. В профиле дерново-подзолистой почвы лесовосстановительной серии без смены пород за 8-летний период отмечен тренд уменьшения Смик и базального дыхания и уже на стадии пихтового жердняка приближение всех эколого-функциональных параметров микробного комплекса к контрольному мелкотравно-зеленомошному пихтарнику
The dynamics of microbial biomass, its structure and functional activity in soils of felling areas in southern taiga fir forests have been studied; they represented different stages of natural regenerative successions. In the upper organomineral horizons of soddy-podzolic soils (Albic Glossic Retisol (Loamic, Cutanic, Ochric)) of the succession series after felling, recovering through a substitution of fir by birch, an increase in the content of Cmic and the intensity of basal respiration from recent felling to the stage of pole-wood is noted. The soil of pole-wood stage has the highest total reserves of Cmic (170 g C/m3) and microbial production of CO2 (528 mg СО2–С/m3 per hour), exceeding control by 80–85%. In the humus-accumulative soil horizon of the studied succession series, there was a tendency of decreasing both the proportion of fungal to the total substrate-induced respiration, and the ratio of fungi/bacteria in comparison with the control. In the middle-aged deciduous forests with dark-coniferous undergrowth, all the considered parameters of the microbial complexes decreased, but continue to exceed the control. In the profile of soddy-podzolic soil of the reforestation series without species change for 8-year period, the trend of reducing Cmic and BR was noted; already at the stage of fir of pole-wood the approximation of all ecological-functional parameters of the microbial complex to the control short grass–green moss fir forests was observed

Аннотация: The structure of flora and fauna, which is a standard of the state and dynamics of the taiga forests in humid climatic facies of the Altai-Sayan mountain region, has been analyzed based on the example of the undisturbed mountain Siberian Pine taiga (Eastern Sayan mountains). The ecological-phytocenotic features and floristic and faunistic composition of the late succession stage are studied. The dominance of the green moss group of forest types is revealed across the topographic profiles. The forest stands have a complex age structure with the dominance of Pinus sibirica Du Tour. and are characterized by low productivity (quality classes IV-V prevail), high class of normality (from 0.5 to 1.0), and sufficient regeneration. A floristic, ecological-coenotic analysis of the herb-dwarf-shrub layer, the elements of undergrowth, and the moss cover indicates the dominance of humid taiga flora. The species of the taiga ecological-coenotic group (ECG) (Vaccinium myrtillus, Carex iljinii, Calamagrostis obtusata, Gymnocarpium dryopteris, Phegopteris connectilis, Oxalis acetosella, Aegopodium alpestre, Trientalis europaea, Linnaea borealis, Maianthemum bifolium, Stellaria bungeana, et al.), moss-bog ECG (Ledum palustre, Vaccinium uliginosum, Carex globularis et al.), and bor-taiga ECG (Vaccinium vitis-idaea, Pyrola rotundifolia, Lycopodium annotinum et al.) form the herb-dwarf-shrub layer in the prevailing forest types. Green mosses (Hylocomium splendens and Pleurozium schreberi with a mixture of Ptilium crista-castrensis and Rhytidiadelphus triquetrus) dominate in the moss layer. Polytrichum commune, P. strictum, Dicranum scoparium, D. polysetum, and Sphagnum sp. mosses are found in some sites. The increased role of higher spore plants characterizes the flora as well-preserved archaic features flora. The Siberian pine forest coenoflora consists of 224 species and belongs to the Cyperaceae type. In the structure of the geographical elements of the flora, the leading role belongs to the Palaearctic, European, and Siberian elements with an increased role of endemics. The species typical for the Siberia taiga complex compose the core of the fauna. The most diverse avifauna is represented by 102 species (Tarsiger cyanurus, Parus montanus, Parus ater, Luscinia calliope, Sitta europaea, Loxia curvirostra, Coccothraustes coccothraustes, Tetrastes bonasia, Phylloscopus proregulus, etc.).

Аннотация: The dynamics, structure, and functional activity of microbial biomass have been studied in soils of felling areas in southern taiga fir forests (the Yenisei Ridge, Krasnoyarsk krai), which are at different stages of natural regenerative successions. The top organomineral horizons of soddy-podzolic soil (Albic Glossic Retisol (Loamic, Cutanic, Ochric)) of the after-felling regeneration succession (with the stage of secondary birch forests) is characterized by an increase in the content of carbon of microbial biomass (C-mic) and in the intensity of basal respiration from new felling to the stage of dense young forest. In the soil of the dense young-wood stage, the total reserves of C-mic (170 g C/m(3)) and microbial CO2 production (528 mg CO2-C/m(3) per hour) are the highest and exceed the control by 80-85%. In the humus-accumulative soil horizon of the studied succession series, there is a tendency for a decrease in the portion of fungal substrate-induced respiration and in the fungi to bacteria ratio in comparison with the control. In the middle-aged deciduous forests with dark-coniferous undergrowth, all the considered parameters of microbial complexes decrease but remain higher than the control. A trend for a decrease in C-mic and basal respiration is revealed in the profile of soddy-podzolic soil of the regeneration series without species change over an eight-year period. At the stage of fir dense young forest, all ecological-functional parameters of the microbial complex become closer to the control small-grass-true-moss fir forest.

Аннотация: The vegetation cover characteristics of anthropogenically disturbed birch stands of Krasnoyarsk forest-steppe are studied. The research purpose is to study the current state of under-story vegetation cover of the birch stands, which have been exposed to recreational and anthropogenic impacts for a long time, as well as to assess the degree and nature of its change over the 12-year period since the last research. The studies were carried out on the sample plots laid out in mixed herbs birch stands. Cenosises are characterized by V-VI age classes, II-IV quality classes, and 0.6-0.9 density of stocking. The birch stands are located in the main transfer of Krasnoyarsk industrial emissions. Phytocenoses were under significant anthropogenic and recreational impact for a long time. At each facility, 30 sites (1 m(2) each) were laid, where species composition, horizontal and vertical structure, projective cover and occurrence of undergrowth and forest live cover species were assessed. The comparative analysis of floristic lists was performed using the Sorensen-Czekanowski coefficient (K-sc). The degree of species diversity was estimated by using the Shannon index; the degree of recreational transformation - synanthropization index. Cuttings were taken from 10 sites (20 x 25 cm each) for recording the phytomass stock of forest live cover on each sample area. Plants were cut off at the litter level, sorted by species, dried and weighed. Rating scales of digression were used to study the recreation influence. The degree of anthropogenic impact was determined by the content of toxic ingredients in plants of living ground cover. It is found that the toxic elements concentration in plants does not reach excessive values at which homeostasis disturbance happens. It was concluded that the changes in vegetation cover observed in 2017 in relation to the state of 2005 are more due to recreational than anthropogenic impact; which changed due to the introduction of a new technology at the JSC "RUSAL Krasnoyarsk Aluminum Plant", which made it possible to reduce toxic industrial emissions. According to the study results, the species composition of the undergrowth and forest live cover was determined, the features of its change over a 12-year period were revealed. It is noted that species diversity has decreased and the proportion of synanthropic species has increased across all plots. Total forest live cover phytomass and individual species phytomass are determined at each plot. The regularities of change in different species contribution to the total stock of phytomass, depending on recreational impact changes, were identified. The ground cover recreational digression stages are determined by analyzing the changes in species diversity, the quantitative ratio of ecological-cenotic groups, the structure and the absolute value of phytomass.

Аннотация: Исследована изменчивость полиморфных ферментных локусов у 1180 особей подроста в четырех популяциях Pinus sylvestris L., Picea obovata Ledeb. и Abies sibirica Ledeb., произрастающих в условиях южной тайги Средней Сибири, на участках, пройденных рубками разной интенсивности, и в контроле (в том числе, в 15 выборках сосны обыкновенной, 13 выборках ели сибирской и 16 выборках пихты сибирской). Результаты сравнительного анализа данных подтверждают существенное сокращение генетического разнообразия у молодого поколения деревьев трех хвойных видов на месте сплошных широколесосечных и выборочных вырубок высокой интенсивности (на 8–30% – по числу аллелей и уровню полиморфности, на 14–75% – по числу редких аллелей). Отмечено, что генофонды популяций темнохвойных видов более чувствительны к антропогенным воздействиям по сравнению со светлохвойным (сосной обыкновенной). Особенности генетической изменчивости изоферментов в популяциях пихты сибирской свидетельствуют о значительной утрате видом внутривидового аллельного разнообразия ферментных локусов, что требует особого подхода к анализу влияния лесопользования на популяции данного вида и сохранению его генетического разнообразия. Из использованных показателей генетической изменчивости наиболее информативны для целей генетического мониторинга хвойных лесов редкие аллели полиморфных локусов в целом и особенно аллели низкополиморфных локусов
We studied the variability of polymorphic isozyme loci in 1180 individuals of undergrowth in 4 populations of Scots pine (Pinus sylvestris L.), Siberian spruce (Picea obovata Ledeb.) and Siberian fir (Abies sibirica Ledeb.), growing in the southern taiga of Central Siberia, on the sites passed by logging of different intensities and in the control. In total, 15 samples of Scots pine, 13 samples of Siberian spruce, and 16 samples of Siberian fir were studied within the populations. A comparative analysis of the data confirms a significant reduction in genetic diversity of young generation of trees of three coniferous species (by 8-30% in the number of alleles and the level of polymorphism of loci, by 14-75% in the number of rare alleles) in the place of clear large-scale cuttings and selective cuttings of high intensity. It was noted that the gene pools of populations of dark coniferous species are more sensitive to anthropogenic impacts compared with light coniferous (Scots pine). Features of the genetic variation of allozymes in Siberian fir populations indicate a significant loss by the species of the intraspecific allelic diversity of the enzyme loci, therefore it is necessary to use another markers and approach to the analysis of the impact of forest management on the population of this species as well as greater care for the conservation of its genetic diversity. Of the used indicators of genetic variation the most informative for the genetic monitoring of coniferous forests are rare alleles of polymorphic loci in general, and especially rare alleles of loci characterized by a low level of polymorphism. Of the used indicators of genetic variability, the most informative for the purposes of genetic monitoring of coniferous forests are rare alleles of polymorphic loci in general, and especially alleles of low polymorphic loci

Аннотация: The variability of polymorphic enzyme loci was studied in 1180 undergrowth individuals in four Pinus sylvestris L., Picea obovata Ledeb., and Abies sibirica Ledeb. populations growing in the southern taiga of Central Siberia in the regions covered by felling of different intensity and in the control (including in 15 Scots pine samples, 13 Siberian spruce samples, and 16 Siberian fir samples). The results of the comparative analysis of data confirm a significant reduction in genetic diversity in the young generation of trees of three coniferous species at the place of high-intensity clear large-scale and selective felling (by 8-30% in the number of alleles and level of polymorphism, by 14-75% in the number of rare alleles). It was noted that the gene pools of populations of dark coniferous species are more sensitive to anthropogenic effects as compared with light coniferous species (Scots pine). The features of genetic variability of isozymes in Siberian fir populations indicate a significant loss of intraspecific allelic diversity of enzyme loci by the species, which requires a special approach to the analysis of the effect of forest management on populations of this species and preservation of its genetic diversity. Of the used indices of genetic variability, rare alleles of polymorphic loci in general (and especially the alleles of low polymorphic loci) are the most informative for the purposes of genetic monitoring of coniferous forests.

Аннотация: Climate change entails shifts in the ranges of woody plants along both latitudinal and altitudinal gradients in the boreal forest biome. In this study, dendrochronological and GIS technologies have been used to evaluate shifts in the upper distribution limits of trees and shrubs in the Eastern Sayan Mountains. The results show that upward expansion along the altitudinal gradient and increase in projective cover against the background of climate warming reach a maximum in shrubs (Betula spp., Salix spp.); then follow Siberian larch (Larix sibirica Ledeb.), Siberian stone pine (Pinus sibirica Du Tour), and Siberian fir (Abies sibirica Ledeb). The abundance of P. sibirica undergrowth in the mountain forest-tundra ecotone has increased, which is due to a rise in May-August air temperatures (r = 0.97). In zones with sufficient moisture supply (high mountains), warming stimulates radial growth of trees and shrubs and promotes their expansion to the mountain forest-tundra.

Аннотация: Приведена оценка современного экологического состояния компонентов (древостой, подрост, живой напочвенный покров, почва) сосновых экосистем Красноярской лесостепи, произрастающих в зоне многолетнего антропогенного воздействия г. Красноярска и фоновых условиях. Исследования проводили на мониторинговых пробных площадях в сосняках разнотравных. Современное состояние сосняков, произрастающих в зоне многолетнего антропогенного воздействия Красноярска, оценивается как удовлетворительное. Санитарное и жизненное состояние пригородных сосновых древостоев не отличается от фоновых. В сосняках установлено хорошее возобновление сосны. Зафиксировано наличие всходов и значительного количества жизнеспособного подроста. Живой напочвенный покров в сосняках на данный момент (за исключением фоновой пробной площади) находится на стадии слабой рекреационной трансформации. Почвы под изучаемыми сосновыми экосистемами в зоне влияния города относятся к антропогенно-преобразованным, имеют развитые профили с признаками деградации верхних горизонтов
An assessment was given regarding the current ecological state of the pine biogeocenoses components (forest stand, undergrowth, living ground cover, soil) in the Krasnoyarsk forest-steppe, growing in both the zone of long-term anthropogenic impact of Krasnoyarsk and under natural conditions (control plot). The studies were carried out on monitoring sample plots in forb pine forests. The current state of pine forests growing in the zone of long-term anthropogenic impact of Krasnoyarsk is assessed as satisfactory. The sanitary and vital state of suburban pine stands does not differ from the background ones. A good rate of pine regrowth has been established in the pine forests. The presence of seedlings and a significant amount of viable undergrowth was recorded. The living ground cover in pine forests at the moment is at the stage of weak recreational transformation (with the exception of the control sample plot). The soils under the studied pine stands in the zone of city’s influence are anthropogenically transformed, have developed profiles with signs of degradation of the upper horizons

Аннотация: Представлен сравнительный анализ существующих и потенциально возможных методических приемов разграничения зонально-провинциальных объединений лесоболотных и торфяно-болотных комплексов. Показано, что на геоморфологических разностях местоположений в условиях непрерывного взаимодействия с элементами климата, почвами и растительностью осуществляется их относительно автономное развитие во времени и пространстве. На примере северной части междуречья Оби и Томи в соответствии с критериями такой относительной автономности охарактеризованы естественные индикационные вариации таксационной и фитоценотической структуры коренных болотных сосняков и для сопоставления - суходольных. В рядах их современной типологической и морфоскульптурной организации рассмотрены причинно-следственные связи экосистемного разнообразия и продуктивности с водно-минеральными условиями произрастания, однозначно оказывающими влияние на состав возрастных поколений «материнских» древостоев, маломерного подроста и ювенильных групп возобновления. По признакам размерности положительных элементов фитогенного микро- и мезорельефа типизированы крупнобугорковые и подушкообразные поверхности олиго- и мезотрофных сосняков с мшисто-лишайниково-кустарничковой растительностью, в торфяных залежах которых регулярно локализуются мерзлотные водоупоры и ледяные линзы-перелетки. В особо увлажненных эутрофных сосняках с травяно-мшистой и низкотравной растительностью фитогенный рельеф рассмотрен в системе разновысотных, рассеянных и слившихся кочек, а также приствольных бугров, которые образованы каркасами опорно-скелетных корней, драпированных хвойно-листовым опадом, ветошью трав, очесом бриевых (Bryidae Engl.) и гипновых (Hypnales W. R. Buck et Vitt.) мхов. С учетом этих и ряда других факторов оценивается тренд неоднозначного расселения самосева и подроста сосны ( Pinus L.) под пологом «материнских» древостоев. Фитоценотическая и таксационная индикация сосняков, основанная на системно-выборочном методе оценки, расширяет представление о сравнительном диапазоне изменчивости структуры как болотных, так и суходольных сосняков, достигших климаксовой или приблизившихся к ней стадий саморазвития.
In a comparative vein, the existing and potentially possible methodological methods for delimiting zonal-provincial associations of forest-bog and peat-bog complexes are analyzed. It is shown that on geomorphological differences of locations under conditions of continuous interaction with climate elements, soils and vegetation, their relatively autonomous development in time and space is carried out. On the example of the northern part of the Ob and Tom interfluve, in accordance with the criteria of such relative autonomy, natural indicator variations in the taxation and phytocenotic structure of indigenous marsh forests and, for comparison, dry valley pine forests are characterized. In the ranks of their modern typological and morphosculptural organization, causal relationships of ecosystem diversity and productivity with water and mineral growing conditions are considered, which clearly affect the composition of the age generations of the «mother» forest stands, undersized undergrowth and juvenile renewal groups. On the basis of the dimensions of the positive elements of the phytogenic micro- and mesorelief, large-hillock and cushion-like surfaces of oligotrophic and mesotrophic pine forests with mossy-lichen-shrub vegetation are typified, in peat deposits of which permafrost aquicludes and ice lenses-migratory are regularly localized. In especially moistened eutrophic pine forests with grass-mossy and low-grass vegetation, the phytogenic relief is considered in the system of different-height, scattered and merged tussocks, as well as near-stem mounds, which are formed by frameworks of skeletal roots draped with coniferous-leaf litter, grass rags, green Bryidae Engl. and hypnum Hypnales W. R. Buck et Vitt tows mosses. Taking into account these and a number of other factors, the trend of ambiguous settlement of self-sowing and pine Pinus L. undergrowth under the canopy of «mother» forest stands is estimated. Phytocenotic and inventory indication of pine forests, based on the system-sampling method of assessment, expands the understanding of the comparative range of variability in the structure of both marsh and upland pine forests that have reached the climax or approached the stages of self-development.

   Перевод заглавия: RESTORATION OF VEGETATION ON FALLOWS IN KRASNOYARSK TERRITORY’S FOREST STEPPES
Аннотация: Видовое богатство залежных земель лесостепной зоны Красноярского края насчитывает 64 вида сосудистых растений из 50 родов и 19 семейств. Ведущие семейства ценофлоры: бобовые (Leguminosae) (10 видов или 16%), сложноцветные (Compositae) (10 или 16%), мятликовые (Poaceae) (9 или 14%), розоцветные (Rosaceae) (7 или 11%). Основу флоры залежей составили мезофиты (69%) с незначительным участием мезоксерофитов (17%) и мезогигрофитов (9%). Среди эколого-ценотических групп наибольшее участие принимали виды лугово-лесного разнотравья и злаков (34%), рудеральные (22%) и лесостепные (14%). Надземная фитомасса травяного покрова зависела от возраста залежи (p < 0.001) и густоты соснового подроста (p < 0.05). Разнотравно-кострецовые залежи являлись наиболее продуктивными среди залежей лесостепной зоны (1.14 ± 0.11–2.02 ± 0.25 т га–1). Разнотравно-злаковые залежи, испытывающие на себе существенное эдификаторное влияние сосны обыкновенной (Pinus sylvestris L.) (густота 29.6 тыс. шт. га–1 в пересчете в крупный подрост), имели наименьшую надземную фитомассу (0.23 ± 0.06 т га–1). Залежные участки возрастом 7–18 лет активно возобновляются древесной растительностью, где густота сосны обыкновенной варьировала в широких пределах от 0.9 до 29.6 тыс. шт. га–1 в пересчете в крупный подрост. Установлено, что при увеличении густоты сосны обыкновенной происходит снижение числа видов, видового разнообразия, видовой насыщенности, а также проективного покрытия травяного покрова (p < 0.001).
The species richness of the long-fallow lands in the Krasnoyarsk Territory’s forest-steppe zone includes 64 species of vascular plants from 50 genera and 19 families. Leading families of cenoflora are Leguminosae (10 species or 16%), Compositae (10 or 16%), Poaceae (9 or 14%) and Rosaceae (7 or 11%). The basis of the long-fallow lands flora were mesophytes (69%) with an insignificant participation of mesoxerophytes (17%) and mesohygrophytes (9%). Among the ecological-coenotic groups, species of meadow-forest forbs and grasses (34%), ruderal (22%) and forest-steppe (14%) species took the largest part. The aboveground phytomass of the grass cover depended on the age of the fallow (p < 0.001) and the density of the pine undergrowth (p < 0.05). Forb-brome fallows were the most productive among all in the forest-steppe zone (1.14 ± 0.11–2.02 ± 0.25 t ha–1). Forb-gramineous fallows, experiencing a significant edificatory influence of Scots pine (Pinus sylvestris L.) (density of 29600 units ha–1 in terms of large undergrowth), had the lowest aboveground phytomass (0.23 ± 0.06 t ha–1). Fallow plots aged 7–18 years undergo rapid reforestation, with the density of Scots pine varying widely from 0.9 to 29.6 thousand units ha–1 in terms of large undergrowth. It has been established that with an increase in the Scots pine density, the number of species, species diversity, species saturation, as well as the projective grass cover tend to decrease (p < 0.001).

   Перевод заглавия: DYNAMICS OF UNDERSTORY VEGETATION COVER IN ANTHROPOGENICALLY DISTURBED PINE CENOSES OF KRASNOYARSK FOREST-STEPPE
Аннотация: Изучена динамика нижних ярусов растительного покрова в антропогенно трансформированных ценозах сосны обыкновенной (Pinus sylvestris L.) в период 2017-2020 гг. Исследования проведены в разнотравной группе типов леса естественного происхождения в Красноярской лесостепной зоне. Древостои характеризуются I-IV классами бонитета, полнотой 0,5-0,9 и IV-VII классами возраста. На каждом объекте мониторинга на 30 учетных площадках размером 1 м2 был изучен растительный покров: видовой состав, проективное покрытие, встречаемость видов, горизонтальная и вертикальная структура фитоценоза. Интенсивность изменения видового состава за 4-летний период выявлена с использованием коэффициента Серенсена-Чекановского. Видовое разнообразие оценено с применением индекса Шеннона, рекреационная трансформация живого напочвенного покрова - индекса синантропизации. По итогам исследования определен видовой состав подлеска и живого напочвенного покрова, описаны особенности его изменения в период 2017-2020 гг. На основе анализа изменения видового разнообразия, состава и проективного покрытия доминантов и содоминантов, количественного соотношения эколого-ценотических групп установлены стадии рекреационной трансформации напочвенного покрова. В результате увеличившейся рекреационной нагрузки стадия рекреационной трансформации растительного покрова изменилась: на пробной площади 1 - с ненарушенной на 1-ю (начальную) фазу I стадии (слабой трансформации), на пробной площади 3 - с 1-й на 2-ю (заключительную) фазу I стадии. Вследствие отсутствия антропогенного влияния на пробной площади 4 сохранился ненарушенный растительный покров, тогда как на пробных площадях 2 и 5 из-за постоянной рекреационной нагрузки оставалась отмеченная в 2017 г. 2-я фаза I стадии трансформации растительного покрова. Для снижения воздействия на нижние ярусы растительности под пологом сосновых насаждений (пробные площади 1-3) и сохранения ее видового разнообразия можно рекомендовать устройство специальной дорожно-тропиночной сети.
The dynamics of the understorey vegetation cover in anthropogenically transformed cenoses of common pine (Pinus sylvestris L.) in the period 2017-2020 was studied. The studies were conducted in a diverse herbaceous group of forest types of natural origin in the Krasnoyarsk forest-steppe zone. The forest stands are characterized by I-IV classes of bonitet, density 0.5-0.9 and IV-VII class of age. Vegetation cover was studied at each monitoring site on 30 (1 m2) survey plots: species composition, projective cover, species occurrence, horizontal and vertical structure of phytocenosis. The intensity of change in species composition over a 4-year period was identified using the Serensen-Chekanovsky coefficient. Species diversity was assessed using Shannon index, recreational transformation of living ground cover - synanthropization index. Based on the results of the study, the species composition of the undergrowth and living ground cover was determined, and the features of its change in the period 2017-2020 were described. Based on the analysis of changes in species diversity, composition and projective cover of dominants and co-dominants, quantitative ratio of ecological and cenotic groups, the stages of recreational transformation of the ground cover were determined. As a result of the increased recreational load, the stage of recreational transformation of the vegetation cover changed: in sample area 1 from undisturbed to the 1st (initial) phase I stage (weak transformation), in sample area 3 - from the 1st to the 2nd (final) phase I stage. Due to the absence of anthropogenic influence, the undisturbed vegetation cover was preserved in sample area 4, whereas in sample areas 2 and 5, due to the constant recreational load, the 2nd phase I stage of vegetation cover transformation observed in 2017 remained. To reduce the impact on the lower tiers of vegetation under the canopy of pine plantations (sample areas 1-3) and to preserve its species diversity, it is possible to recommend the arrangement of a specific road-trail network.
