Increasure and production of stems and forest plantations – a scientific discipline that studies the laws on the process of growing a tree or whole plantations and determines the ceremony / opportunities of forests in terms of wood mass in different natural conditions. The task of this science is to investigate the quantitative relations between the process of growing the forest and the impact of the factors of the external environment that changes during the lifetime of the trees and plantations. The property of mercury (trees), through the division of cells, increase its volume is a growth. The value for which the diameter, height or volume of the tree or the plant for a certain period of time represents the increase of that element for that time. The production of the plant is the overall annual or periodic wood production in natural indicators (m 3 or tons). There is also a term yield of the plant, which is a quantity of used wood of unit area, from a whole plant or from a whole forest. The forests of the Republic of Macedonia have low production as a result of several factors, and above all, due to the method of cultivation and editing. It is spatially prevailing low-grade forests (71%) with total wood reserve 27.385,300 m 3 or 42.6 m3 / ha and with an ongoing annual increment of 1.4 m3 / ha. High instances and cultures (29%) are with total wood reserve 45.797.112 m 3 or 200 m3 / ha and with an ongoing annual increment of 3.7 m3. Al. And. Natural Reserve Ezerani
