The organization of forest management in intact forest landscapes (IFL) is currently an acute and insufficiently methodologically provided problem, which causes numerous discussions and disputes. Siberia is a wide area and heterogeneous in terms of the disturbance of the territory. The use of natural resources on such vast area has its own specifics, which must be taken into account. Intensive forest management, which covers a significant part of boreal forests, leads to a decrease in biodiversity. Evaluation of the structural, component and functional diversity of forest areas showed that not always one source gives complete information (for example, the absence of an indication of the forest type in the background surveys does not allow to determine the ecological-cenotic group (ECG) of the ground cover plants). The forest management project in the intact territory can be represented by a whole complex of elements (accounting of forest use in adjacent territories, study of background disturbances of the landscape, assessment of species and structural plant diversity, organization of «sparing forest use» in the zone of «limited forest use», identification and description of the most valuable sites by unified criteria, organization of an ecological network) that will support biodiversity and the implementation of environmental functions at the level of ecosystems (large forest landscape). The organization of nature management in IFL requires a whole range of knowledge on various issues of landscape design, ecology, geobotany, silviculture, forest inventory, geoinformation systems, etc. To do this, it is necessary to involve a wide range of stakeholders. Only such an approach will allow, on the one hand, to harmonize rational use of natural resources, on the other hand, to maximally preserve natural landscapes in their natural dynamics.
