The same old pure spruce stands of the eastern region Artvin diameter and height growth models development

A stand growth model is an abstraction of the natural dynamics of a forest stand, and may encompass growth, mortality, and other changes in stand composition and structure. Yield tables developed for various forest types is a growth model. The first yield tables were published in Germany in 1787 and within a hundred years, over a thousand yield tables had been published. Modern yield tables often include not only yield, but also stand height, mean diameter, number of stems, stand basal area and current and mean annual volume increments. As a result of these developments of yield in Europe, a lot of techniques, approaches and models such as growth and yield equations, more detailed stand models, stand tables, transition matrices, and distance-independent and distance-dependent single tree models were developed after normal yield tables.Forestry activities in the forests of the wrong decisions on the compensation of the negative effects difficult. They can get the correct time even as long as 90-100 years of being even possible. In this study, within the boundaries of the Artvin Regional Directorate of Forestry and the same old Diameter and Height Growth Model for Pure Stands spruce has been developed. The model of stand development through time, depending on how the measured shape, and thus more effective for decision-makers may make decisions, they want to be able to have accurate and reliable information instantly, development stands a better given the opportunity to watch.
