The Asiatic wild ass, or khulan, Equus hemionus, is native to the arid landscapes of Central and East Asia. Although the Mongolian Gobi supports the largest population, the species remains threatened by habitat fragmentation, competition with livestock, illegal hunting and climate change. Historically, the khulan ranged widely across Mongolia, including the Eastern Steppe. However, the construction of the fenced Trans-Mongolian Railway in the mid 20th century created a near-continuous barrier to movement, leading to the species’ local extinction east of the railway. In 2019, a pilot conservation initiative removed sections of the fence and documented the first confirmed crossing of the Trans-Mongolian Railway by a khulan in over 6 decades. To assess the current status of khulan east of the railway, we combined GPS data from 29 collared individuals in the South Gobi with distance sampling and opportunistic field surveys. We recorded two confirmed crossings near the Zamiin–Uud border during the winters of 2023 and 2024. Additionally, during field surveys in 2024 we observed 384 khulan in four groups east of the railway. These findings provide the first confirmed evidence of khulan recolonization within their historical range and establish a baseline for future conservation efforts. Strategic investments in wildlife-friendly crossings and habitat restoration east of the Trans-Mongolian Railway are critical to support further recolonization, enhance connectivity and reduce pressure on core populations in the South Gobi.

The Medieval Wall System (MWS), constructed in the tenth–thirteenth centuries AD across parts of Mongolia, China and Russia, was one of several long walls built along ancient frontiers in Asia. Despite a growing body of literature about this network of walls and trenches, many questions still surround its construction and function. Here, the authors present results of archaeological investigations on the Mongolian Arc of the MWS, revealing new construction dates and insights into daily life. Rather than a regimented defence, the MWS, at least in parts, was a symbolic boundary that endured within the social landscape long after it was abandoned.

We report a set of radiocarbon dating of prehistoric settlements located on the paleolake Baruun Khuree shores in the Gobi-Altai area, southern Mongolia. The obtained series of 11 AMS 14C measurements on charcoal and other charred plant macro-remains can be associated with one of the earliest episodes of the Holocene highly mobile desert-adapted hunter-gatherers activities from the Gobi desert (ca. 11,250–10,500 cal BP). Exploiting a wide range of environments, including dune fields, they are characterized by pottery usage and microblade core technology with wedge-shaped cores as well as osteological materials. These preliminary results are part of a project analyzing the nature of long-lasting prehistoric occupation around Tsakhiurtyn Hundi (Eng. Flint Valley)—one of the most extensive early prehistoric sites of Central Asia owing its name to the presence of abundant flint outcrops, lithic workshops and their innumerable flint artifacts.

In 2013, Chinese President Xi Jinping put forward the One Belt and One Road Initiative, commonly known as the Belt and Road Initiative. The initiative proposed ‘peaceful development’ and ‘economic cooperation’ connecting Asia, Europe and Africa. Within this framework, the establishment of the ‘China-Mongolia-Russia Economic Corridor (CMREC)‘ is envisaged as a promising step toward regional connectivity and economic development in Eurasia through the territory of Mongolia. This article analyzes the BRI projects to identify opportunities and challenges to creating the Corridor in Mongolia. The data draw on both primary and secondary sources.

Candelariella ahtii Yakovchenko sp. nov. is described based on phenotypic and ITS nrDNA sequence data. The species, occurring on soil in the crevices and cracks of siliceous rocks, is characterized by its squamulose cushion-forming thallus of imbricate, rounded to weakly incised granules/squamules with a greenish yellow to pale yellow pulverulent upper surface, lecanorine apothecia with a plane to somewhat convex ochre-yellow disc and a permanent thick thalline margin, 8-spored asci and ellipsoid to narrowly ellipsoid ascospores with rounded ends, as well as a distribution in Central and North-East Asia. It is similar to Candelariella citrina but differs in having ascospores without attenuated ends and smaller squamules. Candelariella citrina is excluded from the lichen flora of Russia. A worldwide key to all known Candelariella species with 8-spored asci, including 41 names, is provided.

Almost half of countries globally are implementing national strategies to lower population salt intake towards the World Health Organization’s target of a 30% reduction by 2025(1). However, most are yet to lower population salt intake(1). We conducted process evaluations of national salt reduction strategies in Malaysia and Mongolia to understand the extent to which they were implemented and achieving their intended outcomes, using the findings to generate insights on how to strengthen strategies and accelerate population salt reduction. Mixed methods process evaluations were conducted at the mid-point of implementation of the strategies in Malaysia (2018-19) and Mongolia (2020-21)(2). Guided by theoretical frameworks, information on the implementation, mechanism and contextual barriers and enablers of the strategies were collected through desk-based reviews of documents related to salt reduction, interviews with key stakeholders (n = 12 Malaysia, n = 10 Mongolia), and focus group discussions with health professionals in Malaysia (n = 43) and health provider surveys in Mongolia (n = 12). Both countries generated high-quality evidence about salt intake and salt levels in foods, and culturally-specific education resources in 3 and 5 years respectively. However, in Malaysia there was moderate dose delivered and low reach in terms of education and reformulation activities. Within 5 years, Mongolia implemented education among schools, health professionals and food producers on salt reduction with high reach but with moderate dose and reach among the general population. There were challenges in both countries with respect to implementing legislative interventions and both could improve the scaling up of their reformulation and education activities to have population-wide reach and impact. In the first half of Malaysia’s and Mongolia’s strategies, both countries generated necessary evidence and education materials, mobilised health professionals to deliver salt reduction education and achieved small-scale salt reformulation in foods. However, both faced challenges in implementing regulatory policies and the scaling up of their reformulation and education activities to have population-wide reach and impact could be strengthened. Similar process evaluations of existing salt reduction strategies are needed to strengthen intervention delivery and inform areas for adaptation, to aid achievement of the WHO’s global target of a 30% reduction in population salt intake by 2025.

The Mongolian gazelle Procapra gutturosa is a wild ungulate ubiquitous across the largest remaining temperate grasslands of Mongolia, Russia and China. The species is nomadic and ranges over long distances, resulting in widely fluctuating abundance in any given location. Therefore, a comprehensive and range-wide survey is required to accurately estimate its global population size, but challenges are posed by the expansive geographical distribution and the political boundaries across the species’ vast range. To obtain an estimate of the total population, we compiled data from recent range-wide surveys. During 2019–2020, we estimated the population size in Mongolia by conducting line transect distance surveys and total counts, and by deriving numerical predictions for unsurveyed areas through data analysis. The gazelle's population in Russia was surveyed in 2020 across its summer range using simultaneous counts, transect surveys and expert knowledge. The distance sampling surveys in Mongolia revealed that slightly more than half of the gazelles along the transects were detected. Our assessment of the gazelle population, although probably an underestimate, suggests there are c. 2.14 million individuals in Mongolia and c. 30,000 in Russia. These results confirm that the Mongolian gazelle is the most abundant nomadic ungulate in the open plains across its range. However, to obtain more accurate estimates across all range states and effectively monitor the gazelle?s population status, it is essential to implement standardized survey protocols that correct for imperfect detection. At present, the management of the Mongolian gazelle is inadequate, as there is a lack of regular monitoring to identify any adverse population changes that could necessitate conservation interventions.

The authors present results from a new research project focusing on the prehistory of the area surrounding a vast flint outcrop in Mongolia, called Tsakhiurtyn Hundi, in the borderland between the Gobi-Altai Mountains and Gobi Desert. They present the discovery of a cave and the results of its exploration, confirming its use by Pleistocene hunter-gatherers.

Innovations in horse equipment during the early Middle Ages provided advantages to societies from the steppes, reshaping the social landscape of Eurasia. Comparatively little is known about the precise origin of these crucial advances, although the available evidence points to early adoption in East Asia. The authors present new archaeological discoveries from western and northern Mongolia, dating to the fourth and fifth centuries AD, including a wooden frame saddle with horse hide components from Urd Ulaan Uneet and an iron stirrup from Khukh Nuur. Together, these finds suggest that Mongolian groups were early adopters of stirrups and saddles, facilitating the expansion of nomadic hegemony across Eurasia and shaping the conduct of medieval mounted warfare.

A Mongolian-German project is investigating abandoned early modern military and monastic sites in central Mongolia, including how the ruins of these urban nodes continue to shape cultural memory within nomadic society. Initial excavations have revealed a previously unknown site type, interpreted as garrisons from the period of Manchu rule (AD 1636–1911).

As wildlife becomes more isolated in human-dominated and rapidly changing environments, species conservation requires investment in landscape connectivity. Identifying stepping stones (discrete areas of suitable habitat that facilitate the movement of dispersing individuals) can help meet connectivity goals. We report the occurrence of the snow leopard Panthera uncia in Ikh Nart Nature Reserve, Mongolia, over 250 km from the nearest known population, one of the easternmost records for the species. Ikh Nart Nature Reserve lies within a region considered highly resistant to movement but harbours high densities of argali sheep Ovis ammon and Siberian ibexes Capra sibirica, both important prey items for snow leopards. This occurrence reveals a new distribution record for the species, the capacity of the species to move across low-quality environments, the value of investment in community conservation and collaborative park management, and the role of remote protected areas such as Ikh Nart Nature Reserve as stepping stones for facilitating population expansion and broader connectivity to other potentially suitable but unoccupied areas.
