Abstract :
The following research studies hazelnut (Corylus avellana) growth conditions in various geographical directions in natural ecosystems in a case study from Ardabil Province Fandoqlu forests. To achieve this, habitat range was determined on 1:100000 map through initial circulation forest and studying forest areas. By preparing slope, direction and altitude maps and integrating them in GIS software, land unit maps were provided and finally, 4 land units in hazelnut habitat were determined to study. 16 sample plots were randomly harvested and in each sample plot quantitative parameters (number of hazelnut species group shoot per hectare, number of legs in each group shoot, diameter at breast height group shoot) were measured. Research results suggested that hazelnut species were deployed in geographical directions if north, south and west along with areas without any directions in Fandoqlu forests. North direction is the best geographical direction for growing hazelnut in Ardabil Province Fandoqlu forests.
