Abstract :Considering the recently prepared forest management plans, Oaks, which were previously represented by a single nickname (Quercus spp), are now separated based on their species. Although there are still forest management plans that are using old pseudonyms, the plans that have expired are being renewed while taking into account the distinction between Oak species. There is no study that provides up-to-date information on the spatial distribution, mixture status, and stands’ distribution according to age, site and canopy classes. However, such studies provide valuable information at various levels, ranging from sectorial planning to revealing honey production efficiencies.This study examines the spatial distribution of Oaks across different parameters mentioned above by using the spatial database obtained from the General Directorate of Forestry. ArcGIS 10.8TM software was used to query the attribute data and present it in tables and figures. According to the results obtained, there are a total of 9.05 million ha of Oak stands, of which, 6,116,992.7 ha (67.6%) are pure or mixed within Oak species, and 2,928,775.9 ha (32.4%) are mixed. Pure and mixed stands within Oak species have 2,075,508.4 ha of productive (33.9%) and 4,041,484.3 ha degraded (66.1%). Moreover, 4,986,288.1 ha (81.5%) are managed as high forest and 1,130,704.6 ha (18.5%) are managed as coppice. Considering their developmental stage and crown closure (excluding degraded stands), 94.5% of those were less than 20 cm in dbh (diameter at breast height), with 44.1% of them having more than 70% of the cover. In conclusion, it is recommended that the parameters mentioned above be considered when publishing forestry statistics for Oaks.
