Authors: Butko G , Yakovenko N , Menshikova M , Porotnikov P , Tihomirov E 
Published: November 2021

Abstract
The development and implementation of innovations are becoming integral functions of a modern industrial enterprise. The author has developed an author’s approach to assessing the innovation potential of forest enterprises through the analysis of financial sustainability and the ability to cover their own liabilities to achieve competitive advantages. The methodological research toolkit uses the competitiveness rating of economic entities of the timber industry complex of the Ural region, formed according to several economic indicators of the market segment occupied by the enterprise, the quality of its products, innovation activity and its efficiency, the degree of financial support, innovative research projects and the availability and effectiveness of facilities, as the resulting indicator. The economic profit indicator used to assess the effectiveness of enterprises is positive if the enterprise has managed to earn more than the profitability of similar enterprises, i.e. the enterprise implements innovative projects, which in turn bring additional competitive advantages. The developed approach makes it possible to identify and evaluate the most significant elements of the innovative potential of the enterprise on the basis of the rating assessment, thus allowing to take into account the specific features of the enterprise and its operating conditions.
An assessment of the contribution of forest sector to federal and regional fiscal budgets in Russia
Authors: Glazyrina I P , Demchenko K A 
Published: November 2021

Abstract
The article deals with the problems of effective use of forest ecosystem resources. The purpose of the article is to quantify the socio-economic efficiency of forest management in the regions of Russia. The paper uses the methods of correlation analysis and spatial analysis with the use of Geographic information system technologies. The assessment of the socio-economic efficiency of regional forest management was carried out using the author's methodology. Several quantitative indicators are considered. The calculations allowed us to draw a number of conclusions. In the 2010-2019 period, these indicators in the east of the country, as a rule, are significantly lower than the national average. At the same time, revenues from regional forest management to the consolidated budget of the country in some regions are negative due to the return of the export value added tax. The federal government encourages the development of the forest sector, using the mechanism of Priority Investment Projects, providing significant benefits to large-scale investors. The analysis shows that in general, the Priority Investment Projects mechanism contributes to the development and modernization of the forestry in Russia, but it does not take into account some regional features and needs to be adjusted.

The theoretical and methodological basis of the study was the analysis of scientific works of Russian and foreign scientists devoted to the study of economic security and methodological support for its assessment, modeling of the forest sector, and forest management. The research used methods of multidimensional comparative analysis, as well as traditional methods of processing statistical information. The result of the study is the development of a methodology for rating the economic security of a regional industrial complex and its practical testing in relation to the forest sector of the economy of the subjects of the Ural Federal District. The proposed methodology is universal and, provided that the key provisions are preserved, can be used to assess the economic security of other socio-economic systems.
Floristic core of the Russian Plain pine forests along Pinus sylvestris southern borders
Authors: Kin N O 
Published: November 2021

Abstract
Pine forests - forest tracts on the sandy left banks, where the main area is occupied by plant communities with a predominance of Pinus sylvestris. Due to the significant distance from each other, the floras of the pine forests differ. However, the flora of these pine forests also shares common characteristics. In order to establish the floristic unity of the forests at the southern limit of the distribution of Pinus sylvestris, work was carried out to identify their floristic core. For 20 years, floristic surveys have been carried out in the forests of the steppe and forest-steppe zones. A general floristic list was compiled, with the identification of aboriginal and alien fractions, and the floristic core was established. Revealed: the core of the flora is determined by the pine forest flora with the lowest number of species among the comparable pine forests. The core of the flora of the studied pine forests included 30.8% of the species of the general flora. An increase in the number of analyzed floras will bring accuracy to the determination of the floristic core. This will make it possible to form an understanding of the pine forest flora as a single floristic complex.

Published: November 2021

Abstract
Over the past 10 years, the country’s legal and regulatory framework has been developing instruments related to sustainable development and security in the context of climate change. To investigate the practice of planning measures for adaptation of the Russian forestry sector to climate change, an analysis has been made of the information on planned measures for the conservation of the ecological potential of forests, adaptation to climate change and increasing forest resilience provided in the forest planning documents of the constituent entities of the Russian Federation. The information in the Forest Plans shall be correlated with the results of the vulnerability and risk assessment carried out for the specific forestry conditions and forms an appropriate set of adaptation measures. The conducted study showed that 100% of the constituent entities whose forest plans contain adaptation indicators have planned to carry out adaptation measures to the risk associated with the increased frequency of wildfires. The analysis showed no correlation between the amount of work and the cost of implementing each of the planned adaptation actions and events. At the same time, the validity of risk adaptation priorities in some constituent entities probably requires further refinement and clarification.

AbstractThe effectiveness of the use biologically active substances in the rooting of cuttingsprivet common (Ligustrum vulgare L.) in its introduction in the region of Nizhny Novgorod was studied. The processes of callus adventitious root formation were studied. The research target was an arboretum collection of common privet in Nizhny Novgorod State Agricultural Academy with geographical coordinates 56°19′43” N, 44°00′O7” E and an altitude of 141 m above sea level. Tested nine industrially produced biologically active preparations widely used in tree and forest nurseries to increase the efficiency of rooting cuttings. The positive effect of cutting treatment with biologically active preparations was confirmed. A significant intensity of callus formation was recorded in the variants with profistim (98.50±1.05%) and extrasol (96.50±0.76%). A noticeable increase in the number of adnexal roots was caused by the use of the drugs heteroauxin (24.55±1.08 pcs.) and ferovit (22.00±1.38 pcs.). The best results for the total length of adventive roots were obtained after the use of heteroauxin (266.92±16.71 cm) and ecofus (272.22±14.42 cm). The effectiveness of bioactive drugs in stimulating regeneration processes on privet cuttings, increasing in the intensity of callus formation and the rate of linear growth of adventitious roots has been proven.

Published: November 2021

Abstract
This study aims to assess the possibility of using a biostimulant Verva-spruce based on spruce’s natural phenolic compounds to reduce the time of growing planting material with improved features. The targets were seeds and 1-4-year-old seedlings of Siberian spruce, untreated and treated with the biostimulant. The effect of the biostimulant on seed germination, seedlings growth, and the pigment’s content in needles were studied. Results shown that soaking seeds in biostimulant at a concentration of 0.00025% increased the germination energy and accelerated hypocotyl growth. Moreover, using the biostimulant significantly increased the growth rate of experimental seedlings and heightened the amount of green pigment chlorophyll a up to 2.5 times. In 2020, in order to study the dynamics of the qualitative characteristics of the plants grown using biostimulant, experimental forest plantations of 4-year-old Siberian spruce seedlings were planted in the Altai-Sayan mountain taiga area. The experimental plantation will be monitored at least until the closure of the canopy.

Published: November 2021

Abstract
The work was carried out in three directions: changing the rotation system of mini-tractor, installing remote control of the winch and improving the trailer. The modernization of the mini-tractor in all directions was successfully completed, and the research results were patented. Testing of the improved mini-tractor in real working conditions confirmed our expectations. Replacing the rotary mechanism with steering, installing the driver’s seat significantly reduced operator fatigue when wood skidding. Remote control of the winch reduced the time of wood loading on the trailer by 1.7 times compared to the option without using it. The total time to perform entire technology cycle from cutting trees to loading them on the trailer, skidding and unloading is decreased by 19.4%. Changing the design of the trailer allows to exclude the turn of the tractor train along the skidroad with penetration into the forest and facilitate the loading of harvested timber.

Published: November 2021

Abstract
The aim of the research is to identify the recreational potential of green plantings in the vicinity of the village of Kradikhino, Kichmengsko-Gorodetsky district of the Vologda Region. The research has been carried out according to the methods of a comprehensive assessment of the recreational potential of S.L. Rysin. The research results indicate that the most recreationally valuable plantings are concentrated in commercial forests. Recreational value plantings of Class III predominate in protective forests (60%), and of Class II – in commercial ones (54%). The expediency of recreational use of these plantings by the local population has been noted. The negative impact on the recreation of clear cuttings in commercial forests has been revealed. Some measures have been recommended to optimize the multifunctional use of the forests. Taking into account the high recreational value of commercial forests, it is advisable to create a landscape reserve in the 1st and 11th compartments of the Karyugsky forestry, where scientific work should also be organized to study the effect of recreation on the forest environment.

Published: November 2021

Abstract
The winter-hardy introduced North American Populus trichocarpa Torr. & Gray is of particular interest. The results of the study of some clones of poplar on the experimental sites of the Voronezh region are presented. It was found that the rootability of standard stem cuttings of poplar was 98-100%. The survival of plants during the first 3-5 years varied from 75 to 100%. The growing season in different years was 135-146 days. The yield of standard cuttings on root-cutting plantations under favorable conditions and optimal age varied in different clones from 592 000 to 1 380 000 pieces per ha. The wood stock at the age of economical exploitability (~25 years) reached 400 m3/ha, while the stock of local balsam poplar at the same age reached 220 m3/ha. The green mass of leaves contained 0.22-0.28 feed units/kg. In addition, the content of digestible protein, calcium, phosphorus, carotene, crude protein, crude fat, crude fiber, nitrogen-free extractives and ash was determined. In general, studied clones of P. trichocarpa can be used in short rotation coppices for bioenergy and feed production, as well as in reclamation plantings. Clones of the poplar can be used in hybridization with black poplars to increase their winter hardiness.

Authors: Tsypouk A , Rodionov A , Druchinin D 
Published: November 2021

Abstract
Problems of mechanization of artificial reforestation in the taiga zone are increasing the productivity of manual labour and reducing the costs of subsequent young stand treatment (early tending and early pre-commercial thinning). Petrozavodsk State University has developed the complex of machines and technologies capable to solve these problems. This complex includes: seeder, root-cutter, dynamic hole-maker and mechanical mounder. Seeder and root-cutter are intended for growing enlarged seedlings with an open root system in forest nurseries. Seeder provides mechanization of sowing seeds. Root-cutter is used for pruning the root systems of seedlings during cultivation. Dynamic hole-maker provides strip soil clearing, surface tillage and preparation of holes for manual planting of seedlings. The hole-maker is also capable to make soil scarification and sowing forest seeds. Mechanical mounder provides strip clearing in the forest plot and creation of humus mounds with mineral soil cover for manual planting of seedlings. Basic technological parameters of the complex of machines have been also substantiated at the Petrozavodsk State University.

Authors: Tseplyaev A N , Tseplyaeva A A 
Published: November 2021

Abstract
For the sparsely wooded regions of Russia, and in particular, the Central forest-steppe, new technologies for growing seedlings and seedlings of tree species are extremely important. It provids rapid growth and high survival rate, which is compared to classic technologies. The purpose of our experiment was to establish the effect of temperature screens from pots of various sizes on the temperature in the root zone of the substrate, and, as a consequence, on the growth and productivity of Thuja occidentalis “Smaragd” in plastic pots for three seasons. The most favorable temperature conditions for plants are formed in large pots, which is facilitated by smooth temperature drops in the substrate and a large area of contact between the substrate and the root system. Agrotechnical methods of growing plants have shown the main advantages of “Pot-in-Pot” technology. This is accelerated plant growth due to more efficient use of water and fertilizers on a specially prepared substrate under conditions of minimal temperature fluctuations. Plants, especially large ones, will have a favorable presentation due to better leafing, a well-developed crown, and a large crown diameter. High safety during wintering also increases the efficiency of the technology providing a higher yield and subsequent more intensive growth.

Abstract
Precipitable Water Vapor (PWV) refers to the content of water vapor in the atmosphere which is significant in observing climate changes. The trends and variations of precipitable water vapor in Laoag, Legazpi, Mactan, and Puerto Princesa from 2012-2019, are presented through the use of radiosonde data derived from the database of the Integrated Global Radiosonde Archives (IGRA). These data were analyzed for possible patterns through a time series of its daily, monthly, and annual mean, together with a Lomb-Scargle periodogram, and Mann-Kendall test. The results observed varying trends and variability. Legazpi and Puerto Princesa with a minimum value of 20 mm, observed a gradual downward trend of PWV. Laoag and Mactan detected an upward trend of PWV with a minimum of 10 mm and 20 mm, respectively. It also showed an annual and bi-annual periodicity of PWV. Furthermore, all cities detected an increase of PWV during the wet months of May to September, while the dry months of October to April with slight variations over 8 years. In terms of seasonality, only Laoag observed a slightly different dry season, with January, February, and March experiencing around 5 mm less in monthly PWV variation compared to the other cities. The correlation of surface temperature and relative humidity of PWV observed an overall increasing trend while showing a general moderate positive correlation. This study can be used for future references for meteorologists for upcoming forecasting on the likelihood of different weather phenomena in the Philippines.

Abstract
Sarawak Region of Malaysia is currently experiencing a high demand for capital needs such as transformation forest to plantations, economic development, and improving transportation systems. Those land cover changes will increase primary pollutant emissions and trigger surface O3 formation. Surface O3 is a secondary pollutant and a significant greenhouse gas contributing to climate change and declining air quality. In this study, variations in surface O3 concentrations at urban and suburban sites in Sarawak were explored using the Malaysian Department of Environment data spanning a two-year cycle (2018-2019). The primary aim of this study is to ascertain the variation of surface O3 concentrations reported at four monitoring stations in Sarawak, namely Kuching (SQ1) (Urban), Sibu (SQ2) (Suburban), Bintulu (SQ3) (Suburban), and Miri (SQ4) (Suburban). The study also analysed the relationship between O3 distribution and nitrogen oxides (NO and NO2). The findings showed that O3 concentrations observed in the region during the study period were lower than the maximum permissible value of 100 ppbv suggested by the Malaysian Ambient Air Quality Standard (2020). SQ4 (Miri) at suburban sites recorded the highest average surface O3 concentrations with an hourly average and daily maximum O3 concentration of 15.7 and 89.5 ppbv, respectively. Temperatures, UV exposure, and wind speed all impact the concentration of surface O3 in Sarawak. In all stations, concentrations of O3 were inversely linked with NO, NO2, and relative humidity (RH). This research will assist the relevant agency in forecast, monitor, and mitigate the level of O3 in the ambient environment, especially in the Sarawak Region.
