Pathogenic networks and natural thinning of stands

In pine cultures on an area of 0.66 hectares, 345 trees that had fallen away by the age of 59 and 1436 pathogenic zones were studied using biolocation. The cells of their networks have sides with distance fluctuations of 69-845 cm, and north-south and west-east in the Hartman network, the distances between the zones are 360±5 and 390±6 cm, and in the Kurri network 262±2.7 and 295±3 cm. The cells can be triangular, and one side is longer than the other by a maximum of 4 times. In the Hartman network, 0.55 m zones alternate through two 0.3 m zones. There are three gradations of zone sizes in the Kurri network: 0.33 m, 1 and 2 m. The most important zone is 1 m. To the west-east, it alternates through two zones of 0.33 and 2 m, and in the adjacent row of cells it is always located diagonally, where their number is fixed to four. Hartman zones damage the stem cambium cells within a radius of 29 cm, Kurri zones - 44 cm, as a result, trees gradually die off. For the first time, a “point of early death” with a diameter of 14 cm was found inside these zones, where trees probably died before the age of 10 and therefore left no traces. According to these points, 14 places were found in the rows of crops where, with a high probability, trees simply did not take root. In general, 90.7% of trees fell off in pathogenic zones, in depression belts of other geoactive zones and inside death points, and only 9.3% died due to a small feeding area. This destroys the old paradigm and narratives of forestry with the justification of the fall of trees due to intraspecific competition, which we previously carried out detailed calculations do not confirm, and at an average age competition determines the fall of only about 10% of trees.
