Growth relations in Turkey oak (Quercus cerris) stands in Bursa regional forest directorate

Forests constitute about 80% of the plant biomass in the ecosystems of our world. In addition to the wood raw materials they have, food, shelter, fresh air, medicine, recreation, landscape, fuel, livelihood as well as economic and ecological as well as socio-cultural as a natural source of benefits throughout the history is seen as a natural resource. About 450 species, many subspecies, varieties and natural hybrids of the oak, which will make valuable fruits and leaves for animals except for firewood, leaves and fruit goblets with a high percentage of essence, a pathological formation of precious stones with the precious side provide products. Therefore, there is a need for information regarding the growth, growth and yield of the species in the planning and management of the planning and management strategies of oak forests today and in the future. The prediction of the estimates used in the context of these parameters is the estimation of the tree volume tables. As stated in various workshops, symposiums and general assemblies, it is emphasized that the number of oaks with 18 species in our country should be taken into consideration. For this reason, in our study, the equations for the volume estimations of the Turkey Oak (Quercus cerris L.) stands, which are distributed within the Bursa Regional Directorate of Forestry, were determined and the relationships between the various stands and single tree parameters were presented. The local single- and double-entry volume table were formed and the coefficients were 95% and 97%, respectively. Models are respectively Brenac and Naslund models. The error percentages in the single entry and double entry tree volume tables are close to zero and absolute error percentages are calculated as 9.24% and 3.89%, respectively. In the light of these results, it was determined that the regression equations were compatible with the data obtained and the equations could be used in the region.
