Abstract

Nowadays, recognizing the desirable habitats of wildlife species, especially endangered and vulnerable species, is one of the important approaches in wildlife management and protection. Black Francolin is one of the least populated subspecies of Francolinus francolinus is endangered in Sistan and in order to preserve its genetic resources, in this study, the desirability of Black Francolin habitat was investigated using the Maximum Entropy Analysis (MaxEnt) model. Thus, in the spring of 2018, 65 species presence points in different areas of Sistan plain were identified through field monitoring and random linear transect method and recorded by the Global Positioning System. To validate the model, the area below the ROC receiver operating characteristic curve and the Jacknife analysis test were used. The results of this study showed that in Sistan plain, the optimal habitat of Black Francolin, areas with a topography of slope less than 5% and altitude less than 500 meters above sea level and dry arid climate are cold. According to Maxent, in the Sistan plain, the coverings of Hamada-Rhazya, Phragmites australis, Tamarix sp, and aquaculture and garden are the favorite. The area of desirable areas in the amount of 31188 hectares (1.85%) was calculated.
