Modeling The Potential Distribution of Turkish Oak (Quercus cerris L.) in Kunduz District (Vezirköprü), Turkey

25502

Turkey oak (Quercus cerris L.) is one of the important tree species in hilly and mountainous forest sites of Turkey. Aim of this study was to predict potential distribution of the species in Kunduz district (Vezirköprü), using Classification and Regression Tree Technique (CART) with presence‐absence data. For this purpose, a total of 586 sampling areas (100x100 m) were sampled during the field studies in summer periods of 2014 and 2015. Turkey oak was recorded as presence in a total of 223 plots. On the other hand, totally 21 independent environmental variables were obtained from the digital maps. The potential distribution of the species was modelled by the statistical analysis using these variables obtaining from the district. Results from CART showed that elevation, radiation index and metasantdstone appears to be the most influential factors on the potential distribution of the species in the district, respectively. Consequently, climatic characteristics associated with elevation are the most affected parameters on the potential distribution of species in the district. Hence, the climatic characteristics should be definitely considered in the course of the management strategies of this species. On the other hand, radiation index and bedrock formation found to be other important environmental factors showed that the local climatic and edaphically features play also a partial role in the potential distribution of the species in the region.
