1. Introduction
The Mongolia's Southern Gobi Desert is among the world's largest and most intact arid rangelands, and thus is of global importance (Batsaikhan et al., 2014). This region supports a unique assemblage of native wildlife, including the largest populations of Asiatic wild ass (or khulan, Equus hemionus) and goitered (or black-tailed Gazella subgutturosa) gazelle in the world (Buuveibaatar et al., 2016). For both species, poaching is primary driver of population declines throughout their range (Mallon and Zhigang, 2009; Stubbe et al., 2012), although habitat loss and fragmentation across the species' range may also be important (Clark et al., 2006; Ito et al., 2013a; Batsaikhan et al., 2014). The khulan is categorized as Near Threatened (Kaczensky et al., 2015), while goitered gazelles are listed as Vulnerable on the IUCN Red List (Mallon, 2008). The desert ecosystem is characterized by seasonal extremes of heat and cold, unpredictable precipitation, and accompanying low and dramatically variable pasture productivity (von Wehrden et al., 2012). The overall sparse environment with tremendous interannual variability in high-quality pasture resulted in the development of a nomadic ungulate system. Well-adapted ungulate species in the region survive because of their ability to move long-distances to find suitable habitat (Olson et al., 2010; Kaczensky et al., 2011a). Conservation of this highly dynamic system is particularly challenging because of the large areas required to provide enough pasture for viable populations (Ito et al., 2013b). The Southern Gobi also is rich in mineral deposits (World Bank, 2006), and a number of mining-related development and infrastructure projects are underway or planned (Walton, 2010; Batsaikhan et al., 2014). As extractive industry developments expand across the region, they disrupt migratory movements, fragment habitat, and cause direct or indirect habitat loss (Ito et al., 2008; Kaczensky et al., 2011a). However, little is known about the impacts of mining development and operations on khulan and goitered gazelles and their habitats. Consequently,determining key variables influencing distribution of and the amount of potential habitat available to khulan and goitered gazelle in the vast landscape of the Southern Gobi is crucial to policy makers, managers, and industry for developing mitigation measures and planning landscape-level conservation strategies (Kaczensky et al., 2008; Mallon and Zhigang, 2009). In this manuscript, we present results of statistical analyses using observations of khulan and goitered gazelle group locations, remotely sensed variables, and disturbance indices to produce spatially explicit habitat models for these ungulates. We were particularly interested in determining whether environmental or human associated factors are the main drivers in influencing the distribution and habitat of both species. These results are important for understanding the current drivers of distribution, determining critical habitat for these species, and offering guidance to mitigate impacts from mine and associated infrastructure developments in the region.
