Zoning of Areas with Susceptibility to Oak Decline in Western Iran

Abstract Zagros forests have the greatest impact on soil and water protection in western Iran. Despite this, a significant part of these forests, especially Ilam province, suffered lot due to phenomenon oak decline. The first most fundamental thing person must know when combating this issue is distribution areas forests. Therefore, using parameters affecting decline province based fuzzy logic, map susceptible was prepared. In study, temperature precipitation, slope, aspect, altitude, distance from farmlands, roads forest density were selected as effective gamma overlap method used. results showed that more than 77% are highly extremely This confirms need for rapid action plan protect addition, proposed, which considered fast efficient preparing such maps other areas.
