Аннотация: As part of a Siberian mapping project supported by the National Aeronautics and Space Administration (NASA), this study evaluated the capabilities of radars flown on the European Remote Sensing Satellite (ERS), Japanese Earth Resources Satellite (JERS), and Radarsat spacecraft and an optical sensor enhanced thematic mapper plus (ETM+) on-board Landsat-7 to detect fire scars, logging, and insect damage in the boreal forest. Using images from each sensor individually and combined, an assessment of the utility of using these sensors was developed. Transformed divergence analysis revealed that Landsat ETM+ images were the single best data type for this purpose. However, the combined use of the three radar and optical sensors did improve the results of discriminating these disturbances.

Аннотация: The goal of the study was to provide an analysis of climate impact before, during, and after the Little Ice Age (LIA) on the larch (Larix gmelinii) tree line at the northern extreme of Siberian forests. Recent decadal climate change impacts on the tree line, regeneration abundance, and age structure were analyzed. The location of the study area was within the forest-tundra ecotone (elevation range 170-450 m) in the Anabar Plateau, northern Siberia. Field studies were conducted along elevational transects. Tree natality/mortality and radial increment were determined based on dendrochronology analyses. Tree morphology, number of living and subfossil trees, regeneration abundance, and age structure were studied. Locations of pre-LIA, LIA, and post-LIA tree lines and refugia boundaries were established. Long-term climate variables and drought index were included in the analysis. It was found that tree mortality from the 16th century through the beginning of the 19th century caused a downward tree line recession. Sparse larch stands experienced deforestation, transforming into tundra with isolated relict trees. The maximum tree mortality and radial growth decrease were observed to have occurred at the beginning of 18th century. Now larch, at its northern boundary in Siberia, is migrating into tundra areas. Upward tree migration was induced by warming in the middle of the 19th century. Refugia played an important role in repopulation of the forest-tundra ecotone by providing a seed source and shelter for recruitment of larch regeneration. Currently this ecotone is being repopulated mainly by tree cohorts that were established after the 1930s. The last two decades of warming did not result in an acceleration of regeneration recruitment because of increased drought conditions. The regeneration line reached (but did not exceed) the pre-LIA tree line location, although contemporary tree heights and stand densities are comparatively lower than in the pre-LIA period. The mean rate of tree line upward migration has been about 0.35 m yr-1 (with a range of 0.21-0.58), which translates to a tree line response to temperature of about 55 m C-1.

Аннотация: The results of in situ measurements of radiobrightness temperature at the frequency 1.4 GHz and soil moisture in the surface layer of the test area located in Western Siberia near Omsk are given. It is shown that at low soil moisture these data are in satisfactory agreement with the SMOS data of the levels 1c and 2. In addition, correlation analysis between the topsoil moisture provided with the SMOS, on the one hand, and the forest fire danger index derived on the basis of rainfalls and temperatures recorded by the net of weather stations located in the area of the city of Krasnoyarsk Eastern Siberia was carried out. This effort was made to investigate if the SMOS data can be used to estimate forest fire danger over the areas where no weather stations are availabe. The correlation analysis showed good relationships between SMOS soil moisture data and fire danger indices.

Аннотация: A Russian-American research team investigates the impacts of long-term intensive working of gold deposits on landscapes in the Middle Siberian taiga. These impacts include the displacement of bedrock and alluvial deposits, deforestation, and increasing fire incidence. Landsat 7 satellite imagery and field data were used in assessing the information yield of satellite scanner channels in the process of classification of the registered images. A schematic electronic map was constructed that shows zones of gold mining, predominant vegetation species, cutover and burned areas, and natural and artificial water bodies.

Аннотация: About 10% of the global forest area has been certified by mid-2014. During the past 2 decades, forest management certification also became a tool to support a transition to and ensure sustainable forest management. However, the speed of certification has slowed down and there is an uneven split of the certified area with the majority located in the northern hemisphere. This article aims at providing a methodology for spatially explicit assessment of the global certified forest with special emphasis on the boreal domain in order to help not only monitoring past progress and current performance, but also identifying possible future developments. Results indicate that knowledge of certified forest locations is key to develop certification also into a monitoring and verification tool for important international agreements e.g. on carbon sequestration or deforestation reduction.

Аннотация: Wildfire number and burned area temporal dynamics within all of Siberia and along a south-north transect in central Siberia (45°-73° N) were studied based on NOAA/AVHRR (National Oceanic and Atmospheric Administration/ Advanced Very High Resolution Radiometer) and Terra/MODIS (Moderate Resolution Imaging Spectroradiometer) data and field measurements for the period 1996-2015. In addition, fire return interval (FRI) along the south-north transect was analyzed. Both the number of forest fires and the size of the burned area increased during recent decades (p < 0.05). Significant correlations were found between forest fires, burned areas and air temperature (r = 0.5) and drought index (The Standardized Precipitation Evapotranspiration Index, SPEI) (r = -0.43). Within larch stands along the transect, wildfire frequency was strongly correlated with incoming solar radiation (r = 0.91). Fire danger period length decreased linearly from south to north along the transect. Fire return interval increased from 80 years at 62° N to 200 years at the Arctic Circle (66°33' N), and to about 300 years near the northern limit of closed forest stands (about 71°+ N). That increase was negatively correlated with incoming solar radiation (r = -0.95). © 2016 by the authors.

Аннотация: Рассматриваются особенности антропогенной истории лесообразовательного процесса в бассейне Байкала. Интервал от ретроспективных сведений о состоянии лесов в прошлом до нынешнего их облика охватывает более трёх столетий. Это позволяет анализировать полный цикл развития насаждений разных древесных пород, начиная с этапа лесовозобновления. Изучены основные варианты формирования насаждений и строения древостоев, детерминируемые антропогенными факторами. Рассмотрена пирогенная дигрессия светлохвойных насаждений вплоть до их распада в перестойном возрасте, с последующей регенерацией, а также возможной сменой породного состава и обезлесением. Хозяйственное использование байкальских лесов начиналось с архаичных выжиганий, проводимых аборигенами-промысловиками, и поселенческих рубок. Интенсивному и обширному освоению байкальских лесов предшествовало строительство Транссиба. Наиболее негативные последствия рубок и сопутствовавших им пожаров отмечены в Южном Прибайкалье. Так, на побережье Байкала исчезли кедровые насаждения, сменившиеся березняками и осинниками. Затем последовала нарастающая волна рубок в светлохвойных лесах Селенгинского среднегорья, финалом которой стали концентрированные лесоразработки 1950-х годов. В итоге - смена хвойных насаждений лиственными. Нередко происходило локальное обезлесение, причиной которого была по большей части осложнившаяся пожарная обстановка. Позитивные перемены в лесопользовании инициированы разработками Института леса с начала 1960-х годов. Были предложены экологичные способы и технологии рубок, с обоснованием перечня особо защитных участков леса, в которых рубки исключались. Эти новшества стали основой региональных Правил рубок леса, совершенствуемых по результатам дальнейших исследований. Вся система лесопользования, включая рубки ухода, становилась адекватной высокому биосферному статусу байкальских лесов. Одновременно изучалась пожароопасность лесов, в том числе дифференцированное влияние разных пирологических режимов на лесообразовательный процесс. Наиболее системно изучены последствия пожаров в светлохвойных насаждениях как особенно пожароопасных. С их пирогенной историей тесно связан современный облик лесных массивов.
Specifics of human effect on the forest development in Baikal basin are considered. Retrospective forest records preceding their current state date back to more than three centuries. Thus we could track the whole cycle of development of various forest species starting with reforestation. We studied prevailing pathways of forest formation and varieties of stand structure controlled by human impacts. Pyrogenic digression of light conifer forests preceding the decline in old-growth age, followed by either recovery, or change in species composition, or deforestation. Records of human impacts on Baikal forests start with archaic burning by aboriginal field men, and settlement-related fellings. Robust and intensive exploitation of Baikal forests was preceded by construction of Trans-Siberian Railway. The worst consequences of the cuts and concomitant fires were found in southern Cisbaikalia. For example, the stone pine forests have been substituted by birch and aspen forests on the shore of Baikal. Then there have been increasingly intensive wave of fellings of light conifer forests on middle altitudes of Selenga region peaked by intensive forest exploitation during 1950s. It has come to a change of conifers by deciduous species. Local deforestations have been common given the growing fire intensity. Forest management has changed positively with advancements introduced by the Forest Institute staring at 1960s. The eco-friendly ways and techniques of felling have been adopted, and the list of highly protective forests where fellings were prohibited, have been denunciated. These novelties have come to as a basis of the regional cutting regulations, which continued to be developed according to new findings. The whole system of forest management, including the sanitary fellings, has become increasingly adequate to the high biospheric role of Baikal forests. Simultaneously the fire danger of forests has been studied, which involved the differentiating effect of fire regime on forest forming process. The consequences of fires have been consistently examined in light coniferous forests being fire susceptible to a highest extent. Moreover their fire records are tightly associated with the current outlook of woodlands outlook.

Аннотация: Приведены результаты полувекового изучения природных пожаров в Забайкалье. Выполнены стационарные экс периментальные исследования пожароопасности растительности по всем высотным поясам, репрезентативным ландшафтным местностям и типам леса. Маршрутные исследования проведены в разных природных округах. На про тяжении двух сезонов осуществлен авиамониторинг ландшафтных пожаров. Прослежены долговременные последствия пожаров на Байкальской природной территории и в Центральном Забайкалье. Проанализированы пирологические режимы в растительных комплексах, по каждому из которых определена длительность пожароопасного состояния как суммарная за весь сезон, так и непрерывная за период пожарного максимума. Характеристики режимов по вы сотным поясам приведены в трех вариантах в зависимости от количества осадков за сезон (обычный, засушливый, влажный). Выявлено, что ландшафтные пожары возникают при интенсивном и экстремальном режимах, когда устанавливается исключительная, по сравнению с сопредельными регионами, пирологическая монотонность расти тельных комплексов на большей части территории. В подобной ситуации практически отсутствуют естественные препятствия для огня, кроме широких рек, озер и гребней горных хребтов. Высокая горимость лесов обусловлена пре обладанием в их составе светлохвойных насаждений. Стремительному распространению пожаров способствуют сухие травостои и заросли пожароопасных кустарников, по которым огонь движется почти со скоростью ветра. Установ лено, что некошеные луга, заброшенные выпасы и пашни у поселковых околиц чреваты опустошительными пожарами не только в лесах, но и в населенных пунктах. В ситуации, подобной возникшей в 2015 г., ландшафтные пожары превращаются в природную катастрофу с тяжелыми лесоэкологическими последствиями. Уцелевшие древостои снижа ют продуктивность, изреживаются, а далее подвержены все более усугубляющейся дигрессии от последующих огневых воздействий. На гарях происходит локальное обезлесение, либо длительная смена хвойных насаждений лиственными. Грядущий сток с обширных выгоревших площадей может усугубить загрязнение оз. Байкал. Сделан вывод, что при влечение резервов МЧС для устранения последней огненной стихии в Прибайкалье оказалось малополезным вследствие запоздания. Альтернативой представляется заблаговременное прогнозирование высокого риска возникновения ланд шафтных пожаров с целью оперативной ликвидации возгораний, чтобы оперативно тушить все загорания при уме ренных затратах, не допуская их превращения в природную катастрофу.
This paper presents results of wildfire studies conducted Transbaikalia over the last five decades. Station-based experimen tal investigations into fire hazards of vegetation accomplished at the regional forest fire stations during those years covered all altitudinal vegetation zones, representative landscape localities and forest types. Route investigations were made in different natural areas. Arial monitoring of landscape fires was used during two fire seasons. Long-term effects of fires in the Baikal Natural Area and in Central Transbaikalia were investigated. Fire regimes in vegetation complexes were analyzed and for each of them the duration of the fire hazard was determined both as the total duration for the entire season and as a continuous duration for the period of the fire maximum. Characteristics of the regimes for the altitudinal belts are provided in three versions according to precipitation amounts for a season (normal, dry and wet). It is found that forest fires occur in intensive and extreme fire regimes when most of the vegetation complexes of the region become exceptionally hazardous as compared to adjacent areas. In such a situation, there are almost no barriers to fire, except for broad rivers, lakes and mountain crests. The forest fire fre quency index is high due to a predominance of light coniferous stands. A rapid spread of fires is also promoted by dry grass stands and fire-hazardous shrubs where the fire is spreading nearly as fast as the speed of wind. It was established that unmown mead ows, and abandoned pastures and croplands in the outskirts of villages present the threat of devastating fires not only in forests but also in settlements. In a situation, such as the one that arose in 2015, landscape fires turn to a natural disaster with severe forest-ecological consequences. Surviving forest stands decrease in productivity and increase in self-thinning, followed by an increasing degradation caused by subsequently recurring fires. Burns undergo local deforestation or a long-lasting replacement of coniferous stands by deciduous forests. The future runoff from the burned-over areas is able to enhance pollution of Lake Baikal. It is concluded that the EMERCOM resources used to fight the latest fires in Transbaikalia showed very little promise because of being delayed. A reasonable alternative to EMERCOM would involve advanced forecasting of high risks of fire oc currence in order to rapidly fight fires with moderate expenses without letting them turning to a natural disaster.

Аннотация: Abstract: The DNA polymorphism of seven coenopopulations of Siberian stone pine (Pinus sibirica Du Tour) growing in a region which is typical for mountain taiga pine forests—the northeastern part of the Kuznetsk Alatau—has been studied. According to the data of 11 nuclear microsatellite loci, 44 allelic variants which significantly differed between the studied coenopopulations in composition and frequency of occurrence are identified. The highest level of allelic diversity is found in the Ps_80612 and Ps_1502048 loci, in which eight and seven alleles are detected, respectively. The calculation of the main parameters of genetic diversity have shown, on the whole, a relatively low level of polymorphism of the studied samples (NA = 3.078, NE = 1.877, HE = 0.445, and HO = 0.401). An analysis of the degree of subdivision of coenopopulations has revealed that about 95% of the total genetic diversity is concentrated within populations, while the interpopulation component accounts for only about 5% (FST = 0.049). The diagnosed differences in the level of P. sibirica genetic polymorphism are determined by several factors: the presence of orographic and phytocenotic barriers between the coenopopulations, which define the directions of seed propagation vectors along the watercourses of river basins that form the Chulym River in the eastern sector of the Kuznetsk Alatau and Tom River in the western sector; a significant level of bioclimatic and environmental extremeness of habitats of coenopopulations in accordance with the height above sea level; and anthropogenic pressure, including periodic deforestation and recreational impact on coenopopulations located near settlements. These factors, which have a significant microevolutionary component, determine the adaptation trends of coenopopulations of P. sibirica and morphological singularities and reproductive potential of trees and, ultimately, they control their genetic polymorphism in the studied part of the Kuznetsk Alatau. © 2020, Pleiades Publishing, Ltd.

Аннотация: Исследован полиморфизм ДНК семи ценопопуляций сосны сибирской кедровой (Pinus sibirica Du Tour), произрастающих в характерном для горно-таежных кедровников регионе - северо-восточной части Кузнецкого Алатау. По 11 ядерным микросателлитным локусам выявлено 44 аллельных варианта, существенно отличающихся у изученных ценопопуляций по составу и частотам встречаемости. Самый высокий уровень аллельного разнообразия имеют локусы Ps _80612, Ps _1502048, в которых выявлено 8 и 7 аллелей соответственно. Расчет основных параметров генетического разнообразия показал в целом сравнительно невысокий уровень полиморфизма исследованных выборок ( NA = 3,078; NE = 1,877; HE = 0,445; HO = 0,401). Анализ степени подразделенности ценопопуляций выявил, что внутри популяций сосредоточено около 95 % всего генетического разнообразия, тогда как на межпопуляционную составляющую приходится всего около 5 % (F ST = 0,049). Диагностированные различия в уровне генетического полиморфизма P. sibirica определяются: наличием между ценопопуляциями орографических и фитоценотических барьеров, обусловливающих направления векторов распространения семян вдоль водотоков бассейнов рек, формирующих р. Чулым в восточном секторе Кузнецкого Алатау и р. Томь - в западном; значительным уровнем биоклиматической и экологической экстремальности местопроизрастаний ценопопуляций в соответствии с высотой над уровнем моря; антропогенной нагрузкой, включающей периодические рубки и рекреационное воздействие на расположенные вблизи населенных пунктов ценопопуляции. Данные факторы, имеющие выраженную микроэволюционную составляющую, детерминируют адаптивные тренды ценопопуляций P. sibirica, морфологическое своеобразие и репродуктивный потенциал деревьев и, в конечном счете, контролируют их генетический полиморфизм в исследованной части Кузнецкого Алатау.
The DNA polymorphism of 7 coenopopulations of Siberian stone pine ( Pinus sibirica Du Tour), growing in the region which is typical for mountain taiga pine forests - the north-eastern part of the Kuznetsk Alatau, was studied. According to the data of 11 nuclear microsatellite loci, 44 allelic variants, which significantly differed between the studied cenopopulations in composition and frequency of occurrence were identified. The highest level of allelic diversity is found in the Ps_80612, Ps_1502048 loci, in which 8 and 7 alleles were detected, respectively. The calculation of the main parameters of genetic diversity showed, on the whole, a relatively low level of polymorphism of the studied samples ( NA = 3,078; NE = 1,877; HE = 0,445; HO = 0,401). An analysis of the degree of subdivision of cenopopulations revealed that about 95 % of the total genetic diversity is concentrated within populations, while the interpopulation component accounts for only about 5 % ( FST = 0,049). The diagnosed differences in the level of P. sibirica genetic polymorphism are determined by several factors: the presence of orographic and phytocenotic barriers between the coenopopulations which defined the directions of seed propagation vectors along the watercourses of river basins that formed the Chulym river in the eastern sector of the Kuznetsk Alatau and Tom river in the western sector; a significant level of bioclimatic and environmental extremeness of habitats of coenopopulations in accordance with the height above sea level; anthropogenic pressure, including periodic deforestation and recreational impact on coenopopulations located near settlements. These factors, which have a significant microevolutionary component, determine the adaptation trends of cenopopulations of P. sibirica , morphological singularities and reproductive potential of trees and, ultimately, control their genetic polymorphism in the studied part of the Kuznetsk Alatau

Аннотация: The article examines the prototype of an interactive system to display fire hazard in the forest during the fire season, prototype's main characteristics and development methods of web GIS technologies. The proposed approach tracks changes in a special web map showing the state of fire danger in the forest based on the daily calculation of the fire hazard class under the current weather conditions. The analysis of data on forest types and frequency of fires proves that the calculations should include an increase in the natural fire hazard class concerning grass allotments in spring and autumn, as compared with summer. Changes in the weather conditions over time cause the map of a given area at a given point and time to change in accordance with the fire threats for these allotments. The developed interface for displaying the fire hazard data allows one to select the area under study and time range, as well as configure the data presentation template. The technological means used were the methods of Internet systems and geoportals producing geographic information, modern web technologies, libraries and services, including tools for dynamic representation of data of screen forms in web templates. © Published under licence by IOP Publishing Ltd.

Аннотация: Soil respiration is one of the major ecosystem carbon fluxes and has a strong relationship with climate. We quantified this dependence for the Russian territory based on coupling climate data and in-situ soil respiration (Rs) measurements compiled into a database from the literature using regression and random forest models. The analysis showed that soil properties are a strong factor that mediates the climate effect on Rs. The vegetation class determines the contribution of the autotrophic respiration to the total Rs flux. The heterotrophic soil respiration efflux of Russia was estimated to be 3.2 Pg C yr(-1) or 190 g C m(-2) yr(-1), which is 9-20% higher than most previously reported estimates. According to our modeling, heterotrophic soil respiration is expected to rise by 12% on average by 2050 according to the RCP2.6 climate scenario and at 10% based on RCP6. The total for Russia may reach 3.5 Pg C yr(-1) by 2050. By the end of the century heterotrophic respiration may reach 3.6 Pg C yr(-1) (+13%) and 4.3 Pg C yr(-1) (+34%) based on RCP2.6 and RCP6, respectively. In order to understand to what extent the lack of information on disturbances impact contributes to uncertainty of our model, we analyzed a few available publications and expert estimates. Taking into account the specifics of Russian forest management and regional disturbance regimes, we have found that for the entire territory of Russia, the disturbances are responsible for an increase in heterotrophic soil respiration by less than 2%.
