Spatial Area Distribution of Oaks According to Different Selected Parameters in Türkiye

Considering the forest management plans prepared recently, the Oaks, which were previously represented by a single nickname (Quercus spp), are now separated based on species. Although there are forest management plans using old pseudonyms that are still in use, plans that have expired are being renewed considering Oak species distinction. 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 useful information at many levels, from sectorial planning for example to revealing honey production efficiency. In this study, the spatial distribution of Oaks according to the different parameters mentioned above was examined 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. Within this, 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 mix 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), and 44,1% of them having more than 70% of the cover. As conclusion, it is recommended that Oaks should be given with mentioned parameters, when publishing forestry statistics.
