[ 1 ] - بررسی وضعیت زادآوری طبیعی در تودههای بلوط سیاه (Quercus macranthera) در شرایط فیزیوگرافی مختلف در جنگلهای ارسباران
Natural regeneration ensures the survival of forest stands and sustainable forest development. The present study was conducted to investigate the natural regeneration of Persian oak (Quercus macranthera fisch. & C.A.Mey. Ex Hohen) stands in Arasbaran protected forest. Measurement of the frequency of standard and coppice regenerations was carried out in one-hectare square plots (100 × 100 m) in ...
[ 2 ] - The Influence of landform, Terrain Shape Index and Aspect Slop on the Structural Distribution of Mixed Stands in the Arasbaran Forest by Ordination Method (Case Study: Kaleybarchay Watershed)
The forest structure and stand composition are controlled by several physiographic factors, because these factors play an important role in control the physical and chemical conditions of the environment, including access to light, soil moisture, and nutrients. In this study, the physiographic characteristics indices of the study area including landform index, terrain shape index and aspect slo...
