This region includes Oak forests with dominant species of Quercus brantii. Based on IUCN guidelines, three criteria were used to evaluate the status of this species as follows: Extent of occurrence (EOO), area of occupancy (AOO) and size of population. Based on field studies and taking plots Zeugandra iranica occupies an area of 6 ha. The extent of occurrence was estimated about 98000 ha using GeoCAT software.
