Technogenic forests on the disturbed lands of Western Siberia

State of forest stands, which were originated naturally on mechanically disturbed moor-forestry lands near oil and gas complexes of Surgut Poles’e (Western Siberia) is estimated in the paper. The differences of their timber value from natural stands are also discussed. Newly originated forests on the higher relief technogenic positions differ significantly from natural stands not only by their productivity, but also by their structure and biological diversity. It gives full possibility to call them technogenic forests. ft was unexpected, but the raised role of such forests opened potential productive forces of the Surgut Poles’e. This role showed a necessity of cardinal revision of forestry principles and natural protection of moor-forestry ecosystems. The state of compound technogenic forests witness positive consequences of the destruction of soil cover and significantly surpass the soil damage. Due to this fact, it is necessary to study deeply this phenomenon. The new data concerning this phenomenon will be a scientific development for creation a new normative base for rational natural use and re-cultivation of disturbed forestry parts of Western Siberia
