چکیده مقاله:
The Equus hemionus is distributed in the steppe habitats of desert areas. Equus hemionus onager is one of the five subspecies of E.h. onager that has the lowest population compared to other taxon. Their habits are fragmented and this species are listed as highly endangered in the IUCN Red List. Reintroduction and release of animals to their native and historical areas is an important issue in wildlife management. Kavir National Park has a high habitat similarity to Turan Protected Complex. In the present article, based on the presence data of the of the E.h. onager in the Turan protected area and environmental variables (physiography, land cover and climate), modeling, feasibility and habitat suitability of E.h. onager in Kavir National Park were performed. Population presence data were obtained during the annual census of Turan area between ۲۰۱۱- ۲۰۱۸ (۱۹۵ points). The distribution pattern of E.h. onager showed that the most suitable habitats for this species are located in the east of Kavir National Park. The habitat areas of high and medium suitability of E.h. onager in Kavir National Park were estimated at ۲۹۴۴۰ and ۵۶۷۹۷ hectares, respectively (۶.۵۸% and ۱۲.۶۸%). The results of sensitization and determining the importance of each of the variables in the model showed that precipitation in the wettest season of the year is the most influential parameter in the development of the feasibility model of E.h. onager distribution probability in the study area. Distance to poor rangeland cover (≤ ۲۵%), distance to barren areas, distance to saline lands, total annual rainfall, altitude, Variety of roughness and average annual temperature were other important variables in the development of E.h. onager distribution model, respectively. According to the modeling results, the eastern part of the Kavir National Park near the watering place of Talhe spring is one of the favorable habitats of E.h. onager and has a suitable habitat connection with Dom Dozdan spring and Shoorab Tak area.
