The Given

Forests of Siberia are heterogeneous in species composition, productivity, types and nature of renewability. They are also heterogeneous in patterns of forest distribution on different categories of land, marshes, bare mountains, meadows and percentage of forest cover. This research investigates the main types of woody plants and geographical distribution of forest communities in Western Siberia. The forest zoning of Western Siberia was analyzed to reveal the features of zonal formation of forest biogeocenoses. Forest zoning and ecological and economic assessment of the productivity of forest communities within zones and regions make the basis for outlining the strategic priorities in the given territory, and help to develop a system of forestry and timber processing activities aimed to improve ecological and economic efficiency of forest resources.

Long Term Study

The results of a long-term study on the natural forest dynamics of two forest communities on one sample plot within the Białowieża National Park in Poland are presented. The two investigated forest communities consist of the Pino-Quercetum and the Tilio-Carpinetum type with the major tree species Pinus sylvestris, Picea abies, Betula sp., Quercus robur, Tilia cordata and Carpinus betulus. The results reveal strong temporal dynamics of both forest communities since 1936 in terms of tree species composition and of general stand structure. The four major tree species Scots pine, birch, English oak and Norway spruce, which were dominant until 1936, have gradually been replaced by lime and hornbeam. At the same time, the analysis of structural parameters indicates a strong trend towards a homogenization of the vertical stand structure. Possible causes for these dynamics may be changes in sylviculture, climate change and atmospheric deposition. Based on the altered tree species composition it can be concluded that a simple ≪copying≫ (mimicking) of the processes taking place in natural forests may not guarantee the conservation of the multifunctional character of the respective forests.

Abstract Selected forestry parameters were investigated in the system of tree vegetation and wood-destroying fungi in parks of the Kyiv city along a gradient of recreational transformation. We investigated vitality, age structure and health conditions of woody plants (Acer platanoides L., Aesculus hippocastanum L., Carpinus betulus L., Frangula alnus Mill., Pinus sylvestris L., Quercus robur L., Q. rubra L., Sambucus nigra L., Tilia cordata Mill.), and species, systematic, trophic and spatial compositions of xylotrophic fungi (27 species of xylotrophs representing 22 genera, 16 families, 6 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that the communities of tree vegetation and xylotrophic fungi in parks depend on the degree of recreational transformation of the environment. Vitality, age structure and health conditions of trees altered species composition of xylotrophs.

The paper presents the results of a comprehensive analysis of the species composition of Cheboksary. The analysis of the dendroflora of the urban environment was carried out according to 3 indicators: the territory of woody plants, the occurrence of woody plant species in landscaping, the structure of the landscaping system. The arboreal vegetation of Cheboksary is represented by 73 species belonging to 43 genera and 20 families. The predominant part of the dendroflora is represented by the covered-seeded plants (86,3%), the gymnosperms - 13,7%. In the dendroflora of green areas of the city, the most widely represented families are Rosaceae, Pinaceae, Salicaceae (48%). The analysis of the species composition of woody plants showed that in the functional and economic zones of Cheboksary plantings of general use are represented by 65 species, plantings of limited use - 52 species, plantings along the streets and main roads - 50 species. The analysis of the species composition of woody plants depending on the share of their participation in landscaping revealed that the greatest number of woody plants is used with low (51 species) and medium (50 species) share. The analysis of the degree of participation of woody plants in landscaping in the four identified functional and economic zones of Cheboksary found that the greatest number of taxa prevail with an average participation in the central zone (37 species), the coastal and suburban zones (36 species). The largest number of species of woody plants grow in the green areas of the central functional and economic zone, where the landscaping involved 66 species, the smallest number grow in the green areas of the industrial area (36 species).

The honey flora of the forest plant community is an important forage resource for the development of beekeeping. That’s why it is desirable to assess species composition and total number of honey plants and to determine the honey reserve of the area of the forest community plant. The forest cover of the Orel region is 9.3%, and this cover is distributed on its territory very irregularly. 257 species out of the total number of honey plants in the region are found in the forests. Deciduous forests are dominant in the Orel region including oak, ash, linden, birch and aspen. The results of studies of flowering plants in the forest plant community showed that there is a sufficient number of honey plants in the forest to provide bee families with nectar from spring to late autumn due to the natural flower-nectar conveyor. The assessment of the honey stock of this community shows that the stock equals 4,872 tons from 203 thousand hectares of forest. And bees can sip only about 30% (1,626 tons). It proves that significant honey reserves are concentrated in the forest plant community of the Orel region. The rational use of these reserves will help to solve the problem of reproduction of new bee families of the aboriginal Central Russian breed and to organize a long honey gathering by bees that provide people of the region with honey.

Two Factors

The contributions of forests to the well-being of humankind are extraordinarily vast and far-reaching. They are an important element in mitigating climate change. The aim of the paper is to determine the influence of particular factors on the diversity of the European Union countries in terms of the amount of wood forest resources compared with the country size. Two factors affecting the variable have been analysed in the paper: 1) the growing stock per 1 hectare of forest area and 2) the quotient of the forest area and the land area without inland water. Those two independent variables are directly proportional to the dependent variable, thus the higher the growing stock density and the higher the forest cover, the bigger the amount of wood forest resources of the analysed country. The causal analysis allowed to answer the question how the two factors affect the variable considered in the twenty eight countries, namely, what the direction and the strength of their influence are. The logarithmic method was used to carry out the causal analysis. The average results obtained for the entire European Union were compared with those received for each country separately and, on this basis, final conclusions were drawn. Data for 2005, 2010 and 2015 have been used for all needed calculations.

Water mites (Acariformes, Hydrachnidia, Halacaroidea) were studied in 8 different bogs and fens of Western Siberia. 28 species of Hydrachnidia and 5 species of Halacaridae were found in them. The species composition in the bogs was very different. In the fens the abundance and species diversity were higher than in sphagnum bogs and the fauna were based on spring species. The representatives of the halacarid mites dominated in sphagnum bogs, which were not found in the fens. The specific similarity of the studied bogs was low. At the same time, the peculiarities of seasonal dynamics in bogs and fens were similar and resembled temporary water bodies: high numbers in the spring and an abruptly decline in the summer, with a slight increase in autumn.

Development Data

Forest cover in term of distribution, extent and types, is major information required to manage the forest resources. Notably for Indonesia, which covers by approximately 98 Mha (>50%) forests, consist of 93 Mha (49.6%) natural forest and 5 Mha (2.6%) plantations forest. The forests are invaluable, including significantly preserve carbon, maintain unique biodiversity, support water and mineral cycle, as well as support local and global community. Here we report efforts have been made for years in the Ministry of Forestry for providing land cover information. Those efforts are including early development, data sources selection, method employed, techniques, and classification scheme, as well as problem encountered and approach for improvements.
