Oak trees decline and death of the oak trees are multi-agent phenomena that in the past century have occurred in many of the world’s forests. In recent years the phenomenon of oak decline and mortality of trees in the forests of the Zagros Mountain in Iran has occurred. Oak Forests decline of Zagros in Ilam Province are caused by a complex interaction of environmental stresses and pests. Zoning forest areas according to their susceptibility to decline helps to put off operations and reduces catastrophic losses caused through a wise management plan. Therefore, creation of one regional strategy is very necessary to reduce its damages and maintains natural and oak forests. In this study, AHP model and GIS technique have been used to achieve goals. The results shows that mean annual rainfall, mean annual temperature, annual evaporation, annual moisture and dust buffer have major role in decline of Persian oak in the region. These results also show that majority of the study area (51.19%) lied under moderate hazard zone followed by high hazard (36.70%) and low (8.28%). Furthermore, oak decline hazard zonation map can help research centers in environmental management and planning to control this phenomenon.
