Phantoms of theories of thinning forests

Considered long used by practice postulates: a) the tree feeding area should be optimal; b) trees should be placed evenly. The postulates formed theories that justify the need for thinning, such as thinning, which were supposed to increase the productivity of forests. However, S. N. Sennov first proved that this is not the case, and furthermore the theories of these thinning cuttings turned out to be phantoms. The reason was in ignorance and neglect of the action of two laws: the rank growth law of trees E. L. Maslakov and the main regularity of the morphogenesis of forest stands G. S. Razin. The latter law distinguishes an upward line (increase in growth, progress) and a downward trend (a fall in growth, a regression). Their presence entails different approaches to the management of the stand: active intervention in the phase of progress and passive in the phase of regression. 13 provisions of the old and new forestry paradigm are presented on the development of simple stands. From the new paradigm, new principles of thinning are also emerging: high intensity in young growth and harvesting only of stagnant trees in the middle and ripening age.
