The Russian Far East

Boreal forest areas in the Russian Far East contained very large intact forests. This particular area is considered one of the most productive and diverse forests in the boreal biome of the world, and it is also home to many endangered species. Zeya State Nature Reserve is located at the southern margin of the boreal forest area in the Russian Far East and has rich fauna and flora. However, the forest in the region faced large-scale forest fires and clearcutting for timber recently. The information of disturbances is rarely understood. This study aimed to explore the effects of disturbance and forest dynamics around the reserve. Our study used two-year overlaid Landsat images from Landsat 5 Thematic Mapper (TM) and 8 Operational Land Imager (OLI), to generate forest-cover-change maps of 1988–1999, 1999–2010, and 2010–2016. In this paper, we analyze the direction of forest successional stages, to demonstrate the effectiveness of this protected area in terms of preventing human-based deforestation on the vegetation indices. The vegetation indices included the normalized burn ratio (NBR), the normalized difference vegetation index (NDVI), and the normalized difference water index (NDWI). The study provided information on the pattern of forest-cover change and disturbance area around the reserve. The NDWI was used to differentiate between water and non-water areas. The mean values of NBR and NDVI were calculated and determine the forest successional stages between burn, vegetation recovery, grass, mixed forest, oak forest, and birch and larch forest. The accuracy was assessed by using field measurements, field photos, and high-resolution images as references. Overall, our classification results have high accuracy for all three periods. The most disturbed area occurred during 2010–2016. The reserve was highly protected, with no human-disturbance activity. However, large areas from fire disturbance were found (137 km2) during 1999–2010. The findings also show a large area of disturbance, mostly located outside of the reserve. Mixed disturbance increased to almost 50 km2 during 2010–2016, in the buffer zone and outside of the reserve. We recommend future works to apply our methods to other ecosystems, to compare the forest dynamics and disturbance inside and outside the protected area.

Wild ginseng Panax ginseng C. A. Mey. (Araliaceae) is a rare medicinal plant. The aim of this work is to assess the state of ginseng cenopopulations in the Ussuriysky State Nature Reserve, and to search of indicator species of its optimal habitats. The reserve is located on the southern spurs of the Sikhote-Alin ridge in the basins of the Artyomovka and Komarovka rivers. In the course of route studies in the period from 2012 to 2019, phenological observations, description of habitats, determination of the age status and morphometry of 77 plants found in 8 types of forest were carried out. A large part of the finds belong to the cedar forests hornbeam – 44.4 %. Analysis of the species composition of the immediate environment of the relic, performed on 36-meter sites, revealed 41 species of vascular plants. Based on the generalized analysis of author's and literature data, a list of 7 species–indicators of optimal habitats for ginseng reintroduction was selected: Oxalis acetosella, Phryma asiatica, Hylomecon vernalis, Thalictrum filamentosum, Maianthemum bifolium, Galium davuricum, Carex ussuriensis. The number and composition of associated species varies depending on the type of forest. Long-term observations carried out in the reserve have revealed significant changes in the phenology of P. ginseng. In recent years, there has been a shift in the beginning of the growing season, flowering and ripening of fruits to earlier dates. Modern findings of ginseng in atypical habitats are described, indicating a broader ecological amplitude of its growth than was indicated by the first researchers. The age composition of the population is normal, but incomplete, there are no senile, very few mature generative plants, the rise falls on the group of medium-generative plants. In order to construct a vitality spectrum, plants from the most numerous age group in the generative middle-aged state g2 (n = 22) are ranked according to stem height into three vitality classes: higher (> 55 cm), medium (35-55 cm) and lower (< 35 cm). Frequency distribution analysis revealed predominance plants of the higher and middle classes of vitality. The vital spectrum indicates the equilibrium state of the population. Good fruiting and renewal of ginseng indicates the preservation of the species in the protected area, and the compliance of modern conditions of natural habitats to its ecological optimum.

В Дальневосточном федеральном округе с учетом вошедших в его состав Республики Бурятия и Забайкальского края сегодня насчитывается 62 особо охраняемые природные территории федерального значения, среди них 30 государственных природных заповедников, 14 национальных парков, 16 заказников, 2 памятника природы. Вместе с ООПТ регионального значения охраняемые природные территории Дальнего Востока занимают более 100 млн га. В статье обобщены результаты исследования размерности и состава атмо­сферных взвесей, проводившегося в 6 государственных природных заповедниках Дальнего Востока: Бастак, Ботчинский, Зейский, Норский, Сихотэ-Алинский и Хинганский. В пяти из перечисленных заповедников отбирали пробы свежего снега, а в Хинганском – пробы хвои. Для получения смыва с хвои, пригодного к дальнейшему анализу, образцы хвои погружались в емкость с дистиллированной водой и обрабатывались ультразвуком. В растаявших пробах снега и усиленном ультразвуком смыве с хвои определяли размеры частиц и фракционный состав. Для взвесей из заповедников Бастак и Ботчинский проводили определение вещественного и элементного состава. Показано, что атмосфера исследованных заповедников, находящихся на расстоянии менее 100 км от крупных и средних городов (Бастак, Ботчинский), подвергается воздействию переноса техногенных частиц. В атмосфере этих заповедников обнаружены опасные для биоты нано- и микрочастицы металлов и их соединений (W, Ti, Fe, Ba, Sn, Zn, Zr, Ce, La и Ag), а также повышенное содержание водорастворимых соединений некоторых металлов (в частности, цинка). Заповедники, расположенные на удалении от крупных городов или рядом с малыми населенными пунктами (Норский, Зейский, Хинганский), содержат в атмосфере меньше техногенных частиц. Статья является установочной с точки зрения начала полномасштабного изучения гранулометрического, вещественного и микроэлементного состава атмосферной взвеси ООПТ Дальнего Востока РФ. The Russian Far Eastern Federal District, which since 2018 includes the Republic of Buryatia and the Trans-Baikal Territory, has today 62 specially protected natural areas of federal significance, including 30 state nature reserves, 14 national parks, 16 wildlife preserves, and 2 natural monuments. Together with the protected areas of regional significance, the protected natural areas of the Far East occupy more than 100 million hectares. The article summarizes the results of the study of the particle size distribution and composition of airborne particulate matter, carried out in 6 state nature reserves of the Russian Far East: Bastak, Botcha (Botchinsky), Zeya (Zeysky), Nora (Norsky), Sikhote-Alin and Khingan (Khingansky). In five of the studied nature reserves, we collected fresh snow samples, and in the Khingan reserve – conifer needle samples. To obtain the wash out from the needles suitable for further analysis, the needles samples were put in a container with distilled water and treated with ultrasound according to the described procedure. Particle sizes and fractional composition were determined in melted snow samples and ultrasound-treated washout from needles. PM samples from the Bastak and Botcha reserves were further analyzed for material and elemental composition. It is shown that the atmosphere of reserves located at a distance of less than 100 km from large and medium-sized cities (Bastak, Botcha) is affected by the transfer of technogenic particles. In the atmosphere of these reserves we found nano- and microparticles of metals and their compounds (W, Ti, Fe, Ba, Sn, Zn, Zr, Ce, La, and Ag), as well as increased content of water-soluble compounds of some metals (in particular, zinc). Reserves located at a distance from large cities or close to small settlements (Nora, Zeya, Khingan) contain less technogenic particles in the atmosphere. This is a position article showing that full-scale study of the particle size, material and microelement composition of airborne particulate matter in natural protected areas of the Russian Far East should continue.

Subject. The article addresses the tax liabilities of taxpayers registered in the subjects of the Far Eastern Federal District, which should be paid to the consolidated budget of the Russian Federation, as well as the factors of the said debt growth. Objectives. Our aim is to assess the level of tax debt of regions of the Russian Far East and identify the correlation between the factors and the amount of tax debt. Methods. The study rests on methods of analysis, generalization, grouping, systematization, and the correlation and regression analysis. Results. We analyzed the level of tax debt for the entire Far Eastern Federal District and by region, identified factors affecting the growth of tax debt therein. The paper assesses the structure of tax debt by type of taxes and activity of debtors. The unveiled factors may help control changes in the size of tax debt in the Russian Far East and develop effective measures to improve the debt collection. Conclusions. The study shows that there is an increase in the tax debt in the regions of the Russian Far East, in the VAT in particular. The factor analysis revealed that the volume of sales of wholesale enterprises, investment in fixed capital, the consumer price index have the largest impact on the amount of tax debt.
