Having several mountains, Khojir National Park located on eastern Tehran is considered among habitats suitable for the wild Goat Capra aegagrus aegagrus. Human-wildlife conflict and anthropogenic threats in the park has isolated wild goat from some suitable habitats. Accordingly, the species presence has been restricted in some areas. In order to model the habitat of Capra aegagrus aegagrus, Ecological Niche Factor Analysis (ENFA) Method was used at environment of the Biomapper software. In this research, the specie presence spots were considered as dependent variable while independent variables were defined in the form of a total number of 9 environmental variables. Afterwards, the relevant map layers were prepared and analyzed. The obtained results indicated that suitable habitats for Capra aegagrus aegagrus in Khojir National Park include the areas that their slop and elevation are more than average slope (42%) and elevation (1495m). According to the specialism values, the most important factors affecting the species ecological Niche are elevation, distance from roads and environmental checkpoint. It should be mentioned that villages inside the park impose negative impact on dispersion of the wild goats. It was also specified that asphalt and dirt roads have no impact on dispersion of the species in Khojir National Park.
