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.

Oil production, as well as the transportation of oil and gas through pipeline systems, cause the destruction and man-made transformation of the natural ecosystems of Northern Eurasia, an increase in the area of disturbed lands, and a reduction in the habitats of specially protected plant species. In this regard, the most significant measures for biological diversity are the identification of conditions for the growth of populations of rare plants in man-made biotopes and the development of methods for their conservation and restoration. 12 species (Carex sylvatica, Dactylorhiza baltica, D. fuchsii, D. incarnata, D. maculata, Fragaria moschata, Glyceria lithuanica, Listera ovata, Neottia nidus-avis, Ophioglossum vulgatum, Platanthera bifolia, Veratrum lobelianum) from the Red Book of the Yaroslavl region and 1 species (Dactylorhiza baltica) from the Red Book of the Leningrad region were recorded in the protected area of oil pipelines. Moreover, Dactylorhiza baltica is listed in the Red Book of the Russian Federation. For Dactylorhiza fuchsii, D. incarnata, D. maculata, Fragaria moschata, at the risk of complete destruction of their biotopes, methods of their transplantation, repatriation and rehabilitation have been developed and transferred to the appropriate Department of the Yaroslavl region. For the restoration of biotopes on bulk sand dams of an oil field in Western Siberia, an experimental study of the wild species Leymus arenarieus as a fixative of technogenic sands showed good results.
