The studies were carried out on the dumps of overburden rocks and tailings of poor ores of the chrysotile asbestos deposit. According to the scheme of forest site zoning, the studying area belongs to the pre-forest steppe district of pine and birch forests of the Zabaikal’ye plain province of the West Siberian plain forest site area. The survey sites were laid out on the terraces of the dump along the running lines. Undergrowth was counted at each survey site. It was classified by viability, size (small, medium, large), and life form (tree, bush, scrub). The provision with undergrowth of the indicated type of disturbed soils was defined and recommendations for measures aimed at accelerating the process of reforestation were given. Undergrowth on the dumps is represented by Scots pine (Pinus sylvestris L.), silver birch (Betula pendula Roth.), aspen (Populus tremula L.), and goat willow (Salix caprea L.). Scots pine and silver birch are the dominant species in the undergrowth composition. Large share of Scots pine of scrub and bush form is the specific feature of the developing young growth. These specimens were found among small- and medium-sized undergrowth. It is the undergrowth of these heights that becomes an annual attrition without passing into the large-sized category. The latter is the main reason for faster conversion of the dumps into forest-covered area, for increasing the share of clay particles in the upper 50 cm thick dump layer, or for coating the dump surface by non-traditional fertilizers, in particular sewage sludge. It was noted that silvicultural trend in the dump reclamation on the chrysotile asbestos deposit is the most preferable. Scots pine should be preferred as the primary species for reclamation planning. For citation: Zaripov Yu.V., Zalesov S.V., Zalesova E.S., Popov A.S., Platonov E.P., Starodubtseva N.I.

Legal and technical documents on the implementation of forest management in the Russian Forest Fund have been analysed. It is established that the current regulatory technical documents do not provide practical forestry, management on a zonal (subzonal) typologic basis. Selected forest areas often combine completely different forest conditions to the areas of forest fund which does not contribute to the forest management optimisation. There are a lot of contradictions and recommendation in the normative and technical documents as concerns mature and over mate stands felling, sanitary felling, improvement felling, forest restoration and forest growing that are not substantiated on factual material. That has resulted in conflicts between forest users and control authorities, reduced efficiency of forestry activities and unjustified financial costs. Elaboration of normative and technical documents is required to improve forest management in protective forests, taking into account their intended purpose. The current recommendation does not take into account the latter and only regulate the relative completeness and composition of stands. Reforestation and afforestation are noteworthy in particular. The requirements for the transition to use when creating forest crops only planting material with a closed root system cannot be considered correct for all regions of the country. Also, specifications on the density of the forest crops created require clarifications as well as correlation artificial and natural reforestation. Relevant is the development of tables of trees attrition having in view the operational appointment of sanitary felling. We believe that improving the regulatory framework for forestry in the forest for various purposes will contribute to increasing their productivity and sustainability.
