Thinning: old and new theories

The analysis of the literature on horizontal patterns, the care and cultivation of forests and identify ways to find new factors affecting the productivity of forest stands. Considered old theoretical basis of thinning in the form of a desire for uniform placement and optimization of the feeding area of trees. Describes an unsuccessful experience for its verification. It is shown that there is a law of development of simple single-tiered stands, according to which the development of phytocenosis is clearly divided into two periods: progress and regress. Each requires a different type of forest management: active - a period of progress and passive - in the period of regression that ignores the modern theory of silviculture. It is noted that in the models of development of spruce forests with a large initial density of progress ends in 20-25 years, whereas in initially rare it happens in 40 years. For these reasons, the current in 30-40 years clearing in dense forest stands is hopelessly late and almost useless, and decimation and through cuttings do not have a theoretical basis, effectively destroying the forest and therefore should either be banned or radically changed. The presence of gaps and displays biological groups, which is formed in 28-57% of the trees in different plantations, is an attribute of the forest, and it must be considered in forestry, i.e. biological groups to maintain and not retrieving. Their placement, as well as the formation of gaps is not accidental and may be due to interactions in the system Earth-a plant in geoactive zones and geobiological networks (GBS). According to the author, the gaps are confined to the uncomfortable zones of these networks with sizes ranging from 0.55 to 2.0 m, which occupies about 2% of the area on which the spruce was significantly reduced growth in height by 14%. Clumps of trees occur in areas favorable for their growth; they have dimensions of from 1.0 to 8.0 m and is 25% of the territory. Biological groups, as well as the largest trees in the stands indicate the location of such zones. However, the presence of GBS questioned on the basis that they are biolocation. However, pathogenic network devices determine the technical and objective methods of control, locking the radiation of GBS on the photographs, and they fully confirmed by the evidence of dowsing. In search of reasons for the uneven placement of trees new hypotheses that should be checked, no matter how improbable they may seem.
