Determination of optimal structure of the forest managed for service purpose

Abstract

A regulated forest structure exists that will best fulfill the expected forest value for both protection and service purposes. For the forest functions designated or to be assigned for service production purposes, optimal formations have not been disclosed yet. For this purpose, the optimal forest structure in the aesthetic and recreation managed forest unit in Odayeri planning unit, reserved to the service production function is explained theoretically, and afterwards presented by numerically and graphically. The optimum rotation age obtained with the calculations for the aesthetic management unit was determined as 198 years, the diameter of the target 72 cm and the target volume 270 m3/ha. Since the aesthetic management unit consists of multi-layered and mixed stands, the continuous forest form has been adopted as the management method and the optimal structure has been determined using the French volume method. The recreation management unit consists of fir and beech mixed stands and was managed according to the age class method. In this study, an example of determining the optimal formation for a management unit consisting of mixed forests has been presented.
