Development of Forest Stands. Models, Laws, Hypotheses

Development and management of forest stands is examined through a model of growth. We will discuss the types of ontogeny, biogroups, biorhythms, right and left forms of conifers, heredity, forest selection for rapid growth, "memory" of the descendants of the competition, which was prepared by their parents, biological constants, geo-active zones. For indicators of canopy, forest growth and productivity found periods of increase, the maximum and fall depending on the initial density cenosis. It proposes a law of development of forest stands with allocation of phases of progress and regress. On the basis of this law, we are reviewing provisions for forestry and we give 19 new models of spruce stands. n these models, we found a constant, which I.S. Marchenko proposed. This constant represents the total volume of the crown of the trees and it is constant at the age of 45-110 years in the rarest of the initial density of the models.
