Abstract The paper presents the results of a study of the decorativeness of pines, which are actively grown on the territory of the European part of Russia. Decorativeness is based on the visual perception of plant habitus. The state of the habitus depends on the genotype and adaptive characteristics in certain growing conditions. The study examined 25 decorative features of 56 species. 24 traits were related to vegetative and generative organs. 1 trait was assessed by the method of weight taxonomy as an indicator of originality of all species for 24 traits. Studies have shown that the total score on a 100-point scale of decorativeness in the studied pines varies from 40 in Pinus heldreichii Chirst and Pinus waschoensis Mason & Stockwell to 68 in Pinus patula Schltdl. & Cham. The research results can be applied when choosing species for cultivation on landscaping objects to increase their aesthetic appeal.

Information technologies are more and more introduced into our life. They are also applied in agriculture under the growing conditions of this industry. It is especially important to manage agricultural processes influenced by rapid changes of climate, limitation of various resources. To overcome diverse uncertainty, it is efficient to use information technologies providing forecast information for high-quality management. The developed online system allows optimizing the economic activity on irrigated lands under the changing climate. Its distinctive feature is the scope of coverage of a considerable territory of the European part of Russia and duration of meteorological observations.

There is a relationship between the properties of wood. Percentage of late wood – wood macrostructure characterization is a definite relation to density. This relationship varies slightly depending on the species and environmental factors. Establishment of interrelation of these parameters for wood from different regions and growing conditions, will more accurately judge the quality indicators of wood in specific circumstances. The studies were conducted with a timber of Scots pine growing in the Vologda region. In Ustyuzhansky Forestry two sites differing in conditions of growth are selected - lichen pine forest and blueberry and cranberry pine forest.

The article examines the condition of roads in Siberia in the second half of the 19th century, identifies the related characteristics of the Siberian land vehicles and skills of coachmen obtained in the harsh climatic conditions, with enormous distances between stations and the need to spend long hours in transit. The sources for this article are travel notes and memoirs written at the end of trips. The work of the German geographer and ethnographer R. Andre, travel notes of the American J. Kennan deserve special attention. Among the works of domestic authors who passed through Siberia in the middle or at the end of the 19th century, the notes of the writer A.P. Chekhov, and of the merchants I. Zavalishin and N. Chukmaldin deserve attention. Documents of the State Archive of Tomsk Oblast (GATO), which contain information about the state of communication routes in Tomsk Province, are attracted for a more complete picture. Thus, the documents of the Fund “Tomsk Provincial Administration (1823-1916)” allow, in particular, tracking the passing travelers' reaction to the unsatisfactory condition of roads in Tomsk Province at the end of the 19th century. This article aims to summarize the facts that relate to the state of Siberian roads, land vehicles, skills of Siberian coachmen, as well as to identify the features of travel in Siberia in the second half of the 19th century. In the course of the study, the authors come to the following conclusions. The condition of roads generally did not satisfy people traveling through Siberian provinces. This was especially true during the off-season when the roads were heavily flooded and washed away by rain or meltwater. Our compatriots' negative comments on Siberian roads in general merge into the common chorus of complaints by foreign travelers. Although there were exceptions when both Russian travelers and foreigners praised the state of the roads in some provinces of Siberia, which was reflected in the archives and travel notes. In winter, the moving speed increased because the snow-covered roads were easier to move along on a sled. However, during severe frosts, there was a great risk of freezing on the road. Because of the harsher climate and the need to stay on the road longer than in the European part of Russia, it was necessary to use vehicles with design features that made them more stable in Siberia. The preparations of the coachmen and the coachmen's preparation of their horses for a long journey influenced its successful outcome. Coachmen had large energy expenditure and were to have endurance. Siberian coachmen maintained a high moving speed with the help of their horses. This fact surprised both Russians coming from the European part of Russia and, especially, foreigners.

On the basis of author's graphical analysis method, the typification of lake ecosystems transformation scenarios depending on the size of lakes was carried out. It was confirmed that the type of transformation depends not only on size of the lake, but also on the landscape and climatic region in which it is located. The distinctive features of lake ecosystems transformation types in the European part of Russia and in Western Siberia were analyzed and compared.

The article analyzes problems of the Russia forest complex development related to social, environmental and infrastructure issues, the solution of which is impossible without state participation. The reasons of the poor adaptation of the forest complex market economy to long development periods, as well as the environmental consequences of economic activity, including environmental pollution, depletion of natural resources, loss of biodiversity and damage to public health, are considered. The analysis of the forest complex market economy features is made on domestic and foreign examples, a serious shortcoming of which is the isolation of the investment payback process from the chosen economic development direction. Forest rejuvenation in this way leads to a decrease or even loss of the forests biospheric properties to regulate the surface runoff of atmospheric precipitation and the formation of groundwater reserves. It is known, that in the forests of the European part of Russia have been accumulated large reserves of semi-subsistence conifer and hard wood. It is shown that to involve it in use it is necessary to change the principles of annual use calculations and to actually re-develop the regulatory framework for the intermediate use of forest wood resources. Four forest management units in the forest economy of the forest complex were identified: state forest management and implementation of medium-term and long-term planning of all types of work in forests, taking into account materials of the state forest inventory and assessing the state and trends in the development of domestic and foreign timber markets; protection and protection of forests from fires and other adverse natural factors (insects, fungi, pollution); carrying out planned logging with the differentiated use of all types of wood and the organization of reforestation taking into account the diversity of growing conditions and the possibilities of using the lands of the state forest fund of Russia. It is advisable to create economic mechanisms to stimulate the activities of all enterprises and institutions of the Russia forest complex for the transition to new environmentally sound technologies in the forest. A flexible economic mechanism is needed to include forest management costs in the cost of harvested wood in order to restore the ecological, economic, social and cultural properties of forests.

The results of a sintaxonomical study of plant communities of the Yamozero lake (the North-East of the European part of Russia) are presented. The diversity of the aquatic and helophytic vegetation of the Yamozero lake consists of 16 associations and 2 communities of 6 unions, 4 orders and 2 classes of the floristic classification: Potamogetonetea (7 associations, 2 communities), Phragmito-Magnocaricetea (9 associations). Many of described associations are widely distributed in the Central and the Eastern Europe. Some associations have the boundaries of their ranges. Some communities include 2 rare species of regional level: Isoetes setacea and Sagittaria natans.
