Studied a sample of the largest trees Siberian pine (Pinus sibirica), Siberian spruce (Picea obovata), Finnish spruce (Picea ×fennica), silver birch (Betula pendula) and small–leaved linden (Tilia cordata) subzone in the middle (“Vishera” Reserve) and in the subzone of the southern taiga (forest Perm) in the natural old–growth forests, only 82 pcs., Which are its parameters were close to the plus trees. Near these trees were determined 8 types of geo–active zones (hereinafter “zone”) using biolocation method. It was found that the largest trees in the Siberian pine forests of the reserve formed on a completely unique combination of these zones, with diameters of 1, 3, 4.5 meters with zones of large diameters. 16, 32, 55 m in the same forests of large trees Siberian spruce were localized exclusively on another combination of zones, with diameters of only 1 and 8 m. Further, in the southern taiga, we have studied the large Finnish spruce trees in spruce and linden forest. They were localized on a completely different combination areas than Siberian spruce: 1 m and 3–4.5 m, with preference zones 4.5 m where the biggest linden trees always met on Zones 1 m and within chains of these areas, and. in the majority of cases they were combined with zones of 3–4.5 m, with a preference for zones 3 m, indicating some differences in energy preferences spruce and linden. We were also studied biogroups one or two rocks; it turned out that they form 34–50% of the large trees and the zone diameter 1 or 4.5 m was located most often exactly in the middle between the trees. In this zone diameter is always greater than the distance between the trees, and may therefore be considered biogroups two trees with the distance of 4.0 m even if they are located in an area with a diameter of, for example, 4.5 m.
