The relations of growth and increment in thrace oak forests

In this study, increment and growth relationships of oak forests of Thrace in different ages, densities and site indexes were examined. For this purpose, double-entry tree volume table, site quality table and the density dependent yield table was created with the help of the data provided to 101 sample plots were taken. Density dependent yield table was programmed using VBA macro feature of MS Excel 2010 program. Thus, yield table can be taken as output in computer environment according to the desired age, density and site index. Trends of stand volume and volume elements provided to density - dependent yield table for the oak forest of Thrace according to the age in different site conditions and densities was presented comparatively. Values obtained by density dependent yield table were compared with values of the yield table generated by Eraslan (1954) and Eraslan - Evcimen (1967) for the oak forests. The same comparison also was made with values of the yield table generated by Carus (1998) for beech forests with broad-leaved species
