EVALUATION OF SELECTION OF TREES OF SALIX ACUTIFOLIA WILLD
DescriptionIn order to identify high-genotypes in natural stands of Sacutifolia Willd we worked to identify the categories of breeding trees. Experimentally proved, that for breeding to increase the productivity of bark of Salixacutifolia Willd the selection would be best carried out with plants, the diameter of the barrel of which is in the range of 9 to 16 cm, tree age 15 - 19 years

PYROLYSIS OF FOREST RESIDUES IN THE CHARCOAL FURNACE
DescriptionThe article presents the modernization option of the forest residue furnace that allows speeding up the drying process by boosting it. The dependencies, reflecting the influence of the temperature of the drying process on the heat losses of the furnace and the effect of the load and the moisture content of the feedstock to the fuel consumption for the entire drying process, are presented in the article

ANTHROPOGENIC DISTURBANCE RESEARCH OF NATURAL ENVIRONMENT IN THE CONDITIONS OF SANDPITS
06.00.00 Agricultural sciences
DescriptionIn this article, an anthropogenic influence on natural ecosystem such as an excavation of sand is discussed. Investigations were done in Kuyar Forest District of the Mari El Republic on a sandpit. The adjacent plot of natural forest was taken as a control. For evaluation the degree of environment transformation as a result of sand excavation several indicators were used. As indicators of physical soil degradation - thickness of organogenic horizon and soil density; for assessment a chemical degradation – content of main nutrients and humus; as an indicator of biological degradation – the level of active microbial biomass. Besides, a potential phytotoxicity was estimated. The study proved: physical and chemical parameters corresponded with the fourth degree of soil degradation, at the same time, biological parameters approximated to parameters of soil from natural territory

PECULIARITIES OF ONTOGENESIS AND POPULATION AGE STRUCTURE OF PULSATILLA PATENS (L.) MILL
DescriptionIn the article we have investigated the ontogeny and the peculiarities of the passage of its stages from Pulsatilla patens (L.) Mill. We have characterized the morphological features of the developmental stages. The age structure of populations and the influence of anthropogenic factors on it have been set

MANAGEMENT PROCEDURE OF LOGGING ROUTES OF OIL AND GAS PIPELINES AT FOREST TERRITORIES
DescriptionProcedure of management by process of routes logging is developed for linear objects (oil and gas pipelines and power lines) by petrol saws, delimbing-bucking machines and timber transport road trains in wood territories. The documents and the performers providing management of operations and the registration of the quality of the works, the resources and the equip-ment, used in the process of logging are defined

GROWTH AND PRODUCTIVITY OF POPULUS TREMULA L. IN THE KOSTROMA REGION
06.00.00 Agricultural sciences
DescriptionA comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
