Chinkara is classified as a vulnerable species (IUCN, 2009). Yet, there is a little information on its biological characteristics and habitat in Iran. This study focuses on the habitat preference and social pattern of this species in Dareh-Anjeer wildlife refuge in 2010-2011. We first determined habitat boundaries of Chinkara in the area. During the survey, 15 transects were located within different habitat types and each transect was observed ~10 times annually. We used landform parameters and plant structure for the habitat type layers in Arc GIS software. Then, we mapped the habitat preference of Chinkara using Jacob’s selectivity index. The group size and sex ratio was obtained by the analysis of field notes. Results of the study showed that Chinkara preferred foothills and hilly plains (Jacob’s selectivity index for foothills was estimated 0.31 and for flat plains 0.03). The foothill habitat type covering 25 percent of the Chinkara habitats in the area provides better resources such as cover and water than the other habitat types. Our results suggest that the Chinkara’s activity in summer and autumn is greatest in the early morning. The mean group size of Chinkara in the area is 2.07±0.32 (n=53, SE=1.17), sex ratio (male/female) is 0.52±0.179, and there is no significant difference between the numbers of males and females in the population.
