Do climatic variations and drought magnitude affect large-scale vegetation composition in the Central Zagrosian forests, and to what extent do topographic variables of altitude and aspect play a role in these potential differences? To answer this question, in this research, the flora list of 15 Central Zagros forests was obtained in five plant life forms between the valleys of two rivers, Gerdb...
In applied studies, identification and study of vegetation, for management and protection of natural ecosystems, are very important. This study was carried out in Vezg forest with an area of 308 hectares located in southeast of Yasouj city. The purpose of this study was to classify ecological species groups and survey their relation to soil physic-chemical properties and physiographic attribute...
