Industrial exploitation of the deposits of the North is followed by the large scale use ofnatural resources (land, water, forest, fish, etc.) along with intensive disturbance andcontamination of the environment. The successful decision of the problem of sustainablenature management is largely determined by the presence of ecologically andeconomically "weighted" system of norms, standards, regulations, which are restrictingthe pressure on the components of the environment. By present in Russia there are morethan 20 state standards concerning the remediation of lands and conservation of soils. TheFederal law "About the recultivation of lands" is under the preparation. But all-Russianstandards are not well adapted for the concrete conditions. Such norms need to beregional. They should take into account the specific of the disturbance of theenvironment, type of waste, climatic and economic conditions along with sustainabilityof the ecosystems.Such technological methods of remediation, as creation ofreservoirs in the depressions oftechnogenic relief, covering of dusty sands (waste of smelter industries) by erosive-stablefractions of minerals, hydro-sowing of the perennial herbs, use of plant vegetativereproduction in recultivation, seem prospective. If natural fertile soil is absent, lakeground deposits can be a source of the local organic fertilizer for the purposes ofrecultivation. Also sideration (sowing followed by plowing at the stage of maximalaboveground biomass) can be used. Such method as the formation of water reservoirs intechnogenic depressions should be wider used. Technological methods should take intoconsideration conservation and protection of the environment. It is important to preventnegative processes leading to the destruction of the landscape. Therefore it is expedient tohave such technical methods for the environmental protection which could allow quicklyand efficiently to stop negative process and to provide ecological safety.

The structure and composition of the forming vegetation at the developed oil field in Western Siberia is considered. The absence of pathologies in plants in reclaimed and self-growing developed areas and the growth of Dactylorhiza maculata (a specially protected plant from the Khanty-Mansi AO Red Book) in the post-technogenic territory testify to the restoration of biodiversity and environmental safety of the emerging post-technogenic communities. Dactylorhiza baltica populations from the Red Book of the Russian Federation have been identified on the Russian Plain in the Leningrad and Yaroslavl Regions in the protected area of oil pipelines. In addition, in the Yaroslavl region, populations of Neottia nidus-avis, Platanthera bifolia, Glyceria lithuanica, Carex sylvatica, Dactylorhiza incarnata, Dactylorhiza maculata, Dactylorhiza fuchsii, Listera ovata, Ophioglossum vulgatum, Veratrum lobelianum, were found. These species are especially protected in the Yaroslavl region. The characteristics of their populations are given: the number of locations, the number of specimens, biotopes. The areas of various grassy biotopes in forest regions are increased through the length of treeless and protected spaces above oil pipelines. Thus these treeless spaces contribute to the conservation of rare and endangered edge-meadow, meadow and bog-meadow plants. Measures for the conservation and restoration of populations of specially protected species are recommended. A suggestion is made about the necessity to expand the assortment of sown plant species when carrying out reclamation work on post-technogenic lands using indigenous species for sowing seeds.

In Saint-Petersburg and its surroundings land reclamation works by hydraulic filling have been performed for several decades. For the hydraulic filling fine-grained slightly silted and clayed sands from the bottom of the Gulf of Finland are used. We have examined the properties of alluvial soils as substrate for planting, figured out unfavorable hydrophysical features of the soils related to soil fractionation caused by water flows while hydraulic filling, which, in their turn, have negative impact on preservation and growth of vegetation. We have given examples of measures on melioration of soils, at the same time having taken into consideration their features while the design performance and working on creation green spaces on the alluvial soils.
