Environmental Impact Assessment of the Forest Management Plan, Using Degradation Model (Case Study: Patom District of Kheyroud Forest)

Forests are as renewable natural resources and because of its abundant environmental values have special status. Given the importance of forests as one of the most important sources of development in the country, several measures such as forest management plans are programmed in Iran. The Review of forest management plans in Iran indicates that in many of plans, the importance of ecosystems was ignored and most of decisions were made irrespective of environmental values. So multifunctional nature of forests, requires environmental impact assessment to be implemented in connection with forest management plans. The purpose of this study is the assessment and measurement of the Degradation coefficient because of human activities in Patom district of Kheyrud forest from the past to present. So, degradation model and degradation fuzzy set model was used that it is one of the environmental impact assessment methods and one of the important tools for the quantification of environmental destruction. The Results of this research showed that %100 of the study area need rehabilitation.
