ASSESSMENT OF CULTURES UNDER FOREST CANOPY OF SIBERIAN CEDAR PINE IN THE TRACT “MAYDAT” IN THE SUBURBAN ZONE OF KRASNOYARSK
Abstract
The forestry and taxation assessment of Siberian cedar pine crops created by nesting under the canopy of an aspen stand in the suburban area of Krasnoyarsk in 1963 was carried out. The average size of trees depends on their number in one planting place – with a decrease in the safety of plants in the “nest”, the average height and diameter of the remaining trees increase by the biological 58-year age. The sizes of the trees leading in the planting places (of the first rank) correspond to the first class of bonitet and are characterized by low variability in all variants, regardless of the safety of plants in the “nest”.
The indicators of the selection coefficient and the relative height of the Siberian cedar pine trees, characterizing the condition of the trees in the “nests”, are calculated. The selection coefficient differs in large values with greater preservation of trees in one planting site, but less variability, which indicates a decrease in competition between trees of dense “nests”, growing under better light conditions than “nests” in which, due to low light conditions, fewer trees were preserved.
It was found that Siberian pine trees growing under a canopy of less complete forests are characterized by the largest sizes.
