Abstract :

Background and Objectives: In order to identify different types of forest stands, present research was carried out in Ile Goran forest located in Kermanshah province with an area of 430 ha. Method: The number of 84 square sampling plots with the area of 1600 m2 by random-systematic sampling mehod and random starting point were established in the study area. Woody species and its origin (high forest or coppice) were observed and recorded in the plots. Based on species composition and species origin, forest type classification was done. First, the map of physiographical unit (elevation, slope, aspect) and landform units were prepared in GIS environment. Findings: The results showed that high forest types (including Quercus brantii and Quercus brantii – Pistacia atlantica type seed) have a narrower range of expansion in terms of altitude than other types. Quercus brantii as an indicator species, the species has wide range of elevation. In terms of land slope, Quercus brantii – Pistacia, either high forest of coppice, have a wider range of propagation than other types and is observed in gentle slopes up to 50% slope. Discussion and Conclusion: The results of this study can be used by experts and planners and help to improve the Zagros forests management.
