Abstract
Gharaviz no hunting area is known as one of the most important habitats of Persian gazelle (Gazella Subgutturosa Subgutturosa) in West Zagros Mountains. Developing models to predict the distribution of wildlife is suitable tool for conservation and management. In this approach, the boundary of the study area was considered the distribution area and then were compared with actual region. Field data collected in the framework of the ecological niche factor analysis (ENFA), used to developing the habitat suitability model by Biomapper software. In the correlation matrix the presence point data as the dependent variable and 14 independent environmental variables were considered. The results showed that Persian gazelle selects hilly areas with the average height of 590 meters, the average southern slope of 13% and a maximum distance of 1290 to 1775 meters of the springs and watering points with the vegetation type Po. bu - An. gr as fall and winter habitat. Persian gazelle in fall more towards the outside and in winter tends to stay within the boundaries of the region. Tolerance factor decreases from fall (0.602) to winter (0.334), which can be the result of anthropogenic impact on environment.
