“…Numerous burial mounds, ritual surface monuments and rock art sites, dating from the late Neolithic (3200 BC) onwards are scattered across its valleys, highlands and steppes. Insights into their density and distribution are limited despite a century of archaeological excavations, but recently, well-directed surveys have shown the full archaeological potential of this broad region (Allard & Erdenebaatar 2005;Bourgeois et al 2007;Krupochkin 2009;Wright et al 2009;Jacobson-Tepfer & Meacham 2010). Unfortunately, infrastructural growth, intensive agriculture and increasing tourism are putting pressure on the archaeological heritage (Plets et al 2011a).…”
