Optimum structures of Black Sea Region fir forests.

Abstract

It is known that fir, being a shade-tolerant tree species, form selection forests which have naturally self-specific increment and growth laws. Because of that they are managed as even-aged forests or in the direction of allowable cut formulas which are not suitable to its natural structure, their optimum structures and ecosystems of these forests being spoiled. With the applied management form contrary to the concept of today’s sustainable forestry, these fir forests are managed at a level of very small increment. Whereas, if they are managed as selection forest, both its ecosystem improvement and sustainability will be provided and a contribution will be made to the economy of the country, running them with an increment potential equal to or more than 13 m 3 /ha. In this paper, the information about increment and growth laws which provide posibilities to manage the Black Sea Region fir forests as selection forests will be given.
