The Uvs Nuur Basin (1,068,853 ha), is the northernmost of the enclosed basins of Central Asia. It takes its name from Uvs Nuur Lake, a large, shallow and very saline lake, important for migrating birds, waterfowl and seabirds. The site is made up of twelve protected areas representing the major biomes of eastern Eurasia. The steppe ecosystem supports a rich diversity of birds and the desert is home to a number of rare gerbil, jerboas and the marbled polecat. The mountains are an important refuge for the globally endangered snow leopard, mountain sheep (argali) and the Asiatic ibex. © UNESCO

Diversity of landscapes, ecosystems and habitats
Criterion
(ix)
Uvs Nuur Basin is an ancient, enclosed and remote salt lake system in Central Asia that comprises a wide range of interconnected landscapes, ecosystems and habitats of high degree of naturalness. These include cold desert, desert-steppe, steppe, taiga, alpine tundra, boreal, deciduous and floodplain forests, river valleys with associated wetlands, saltmarshes and saline lakes (UNEP-WCMC, 2011). The international importance of Uvs Nuur Basin stems from its large-scale undisturbed climatic, hydrological and ecological processes and phenomena (World Heritage Committee, 2014). Because of the unchanging nature of the nomadic pastoral use of the grasslands within the basin over thousands of years, the area provides researchers with an invaluable natural laboratory for understanding long-term ecological processes, including the still intact processes of lake salinisation and eutrophication. Past and current research on both sides of the border, in Mongolia and the Russian Federation, has shed light on the basin's unique geophysical and biological features, further highlighting its global significance. Recognizing this, the Uvs Nuur Basin has been selected as a field site for the International Geosphere-Biosphere Programme (IGBP), a worldwide initiative aimed at monitoring and understanding global change (World Heritage Committee, 2014).
Threatened and endemic plants
Criterion
(x)
The flora and vegetation of Uvs Nuur Basin reflects its wide range of habitats: 552 plant species have been recorded, 234 of them restricted to the mountains of southern Siberia and northern Mongolia; 52 are relict species, 19 are recorded as endemic to Mongolia and Tuva, while five are endemic to Uvs Nuur: Astrogalus polozhinae, Juncus salsuginous ssp.tuvinicum, Stipa barhanica, Astragalus tuvinicus and Zygophyllum pterocaprum ssp.tuvinicum (UNEP-WCMC, 2011). The vegetation zones are clearly layered by altitude. The joint management plan of the site lists even higher species numbers, among them many rare ones (Joint management plan, 2010).
Rare and threatened bird species
Criterion
(x)
The avifauna of the Uvs Nuur Basin series is similarly complex and habitat-depended as its mammal fauna. 359 bird species have been recorded (IUCN, 2003), many of which are of international conservation importance, including the Siberian Crane (Leucogeranus leucogeranus) (CR), Red-crowned Crane (Grus japonensis) (EN), Dalmatian Pelican (Pelecanus crispus) (VU), White-headed Duck (Oxyura leucocephala) (EN), Great and Asian Houbara Bustards (Otis tarda and Chlamydotis macqueenii) (VU), Relict Gull (Larus relictus) (VU), Eastern Imperial Eagle (Aquila heliaca) (VU), Asian Dowitcher (Limnodromus semipalmatus) (NT) and both Cinnereus and Bearded Vultures (Aegypius monachus and Gypaetus barbatus, both NT) (IUCN, 2017; UNEP-WCMC, 2011). Some of the migrating birds that use Uvs Nuur as a temporary habitat are rare: Bewick’s Swan (Cygnus columbianus), the globally vulnerable Lesser White-fronted and Red-breasted Geese (Anser erytrhopus and Branta ruficollis), and the Baikal Teal (IUCN, 2017; UNEP-WCMC, 2011).
Rare and threatened mammals
Criterion
(x)
The various ecosystems of this complex serial property have distinct mammal faunas. 173 species of mammals have been reported for the Mongolian part of the property alone, while the corresponding number for the Tuvan reserves appears to be 72 (UNEP-WCMC, 2011). These include Snow Leopard (Uncia uncia) (EN), Siberian Marmot (Marmota sibirica) (EN), Siberian Musk Deer (Moschus moschiferus) (VU), Marbled Polecat (Vormela peregusna) (VU), Argali (Ovis ammon) (NT), Pallas’s Cat (Otocolobus manul) (NT), Eurasian Otter (Lutra lutra) (NT), and the rare Mongolian Gazelle (Procapra gutturosa) (IUCN, 2017; UNEP-WCMC, 2011). The presence of the globally endangered Asiatic Wild Dog (Cuon alpinus) is questionable (IUCN, 2010, 2017). There are also many other charismatic mammal species typical for their habitats, including carnivores such as Brown Bear (Ursus arctos) and Eurasian Lynx (Lynx lynx), herbivores such as Siberian Ibex (Capra sibirica), Reindeer (Rangifer tarandus), small mammals and bats. Monitoring of large mammals in the two protected areas indicated that Turgen Uul contains around 7,000 ibex and 200 argali, while Tsagaan Shuvuut probably holds 2,000 ibex and 800 argali (IUCN, 2003).
Other rare and threatened fauna
Criterion
(x)
Uvs Nuur Basin holds globally important herpetofauna, ichthyofauna and entomofauna. 16 out of the 20 rarely met species of beetle are endemic. Two endemic fish species (Oreoleuciscus potanini and O. pewzowi) have been recorded. There are also four isolated populations of reptiles: Toad-headed Agama (Phrynocephalus versicolor), Multicellated Racerunner (Eremias multicellata), Gobi Racerunner (Eremias przewalskii), and patterned Grass Snake (Elaphe dione).
Assessment information
The low level of urban population, negligible human impact and lack of industry in both Tuvan and Mongolian sectors of the site still ensure the protection of the site. Its geographic isolation, climatic extremes, and limited surface water flow make it an unattractive locality for agricultural industries. Apart from overgrazing, which only affects some of the ecosystems of the site, there are very few serious threats to the natural environment of Uvs Nuur Basin. Poaching and illegal logging are of some concern, but their impact on target fauna and flora appears to be relatively low. Fires cause harm to the forests in and around the site but are currently perceived as a low threat.
Mining & Quarrying
(Small scale mining)
Inside site
, Localised(<5%)
Outside site
Small scale mining operates in the transition zone on both the Mongolian and Russian parts of the site (Schuerholz et al., 2007; Butorin, 2005). Illegal vehicle traffic from the salt mine traverses the northern section of the Special Protected Area (SPA) on the Mongolian side. In terms of Uvs Nuur water quality, mining apparently does not cause any impacts (Walther, 2020).
Logging, Harvesting & Controlling Trees
(Illegal logging)
Inside site
, Scattered(5-15%)
There is little potential for commercial forestry in the site and the forest use has been limited by the collection of non-timber forest products, firewood and poles and fencing for livestock keeping (IUCN, 2020). However, there are concerns about illegal logging in some areas of the World Heritage site (World Heritage Committee, 2014), which need to be understood better. With the increase of domestic need for timber, the forest use could increase significantly.
In a study of land cover change in the Uvs Lake Basin ecoregion, Jamsran et al. (2019) found that between 1995 and 2015, the forest area in the basin decreased by almost 25%, mostly due to illegal logging, but also forest fires and pest damage.

Fire & Fire Management
(Forest fires)
Inside site
, Extent of threat not known
Outside site
Forest fires cause harm to the forest areas in the site (Uvs Basin Management Plan, 2000; Jamsran et al., 2019). The incidence and frequency of forest and steppe fires increased in recent years due to dryness in overall climate and negligent human attitudes. However, measures such as strict anti-logging laws, improved conservation management and expanded training and ecological education have been implemented to mitigate against human induced forest fires (IUCN, 2020a).
Hunting, Collecting & Controlling Terrestrial Animals
(Poaching)
Inside site
, Extent of threat not known
Outside site
Low-level subsistence and possibly recreational poaching exists in the site (UNEP-WCMC, 2011). Some of the main targeted species include snow leopard, manual (Pallas’s cat), argali, Siberian ibex, maral wild reindeer, dzeren (Mongolian gazelle), musk deer, beaver, red fox, and Mongolian bobak (Uvs Basin Management Plan, 2000). Weak enforcement capacity in combination with increasing visitation (at least on the Russian side) leads to an increase in poaching (IUCN, 2017). WWF Russia supports anti-poaching activities in the area.
Terrestrial Animal Farming, Ranching & Herding
(Overgrazing)
Inside site
, Scattered(5-15%)
Outside site
With the emergence of individual peasant economies after the collapse of collective system of animal husbandry, the number of moves and distance between seasonal pastures has decreased substantially (Uvs Basin Management Plan, 2000). This creates concentrations of domestic animals in the vicinity of water sources. However, despite there being relatively few people with livestock living in the area (IUCN, 2020), competition for pasture is generally increasing and the habitat area available to wild ungulates, in particular Argali, is shrinking. Overgrazing can directly lead to erosion and the reduction of productive grassland areas and thus convert these to bare lands, especially when accompanied with serious water stress (Jamsran et al., 2019; World Heritage Committee, 2014). WWF Mongolia/Mongolian Protected Areas, (2022) noted that overgrazing is assessed as relatively minor in comparison to other threats in the Uvs Nuur area. Nevertheless, the number of livestock in Uvs Nuur area has increased rapidly, e.g., between 1990 and 2017, the number of animals doubled from 1,6 to 3,1 million (Walther et al., 2020; IUCN, 2003).
Overall increase in annual temperature has been observed throughout the whole region and climate change might ultimately result in dryness of the area and increased frequency of forest and steppe fires, as well as desertification. The area is sensitive to environmental changes, but more data is needed to make predictions of climate change impact, based on long-term monitoring and research on the natural environment of the site. Further information is also required in relation to the impact of the potential mining, although, the assessment of the scientific and technical council of the reserve not to grant the permission for exploration is promising. Other potential threats include possible road construction and tourism impact.
Roads, Trails & Railroads
(Road infrastructure development)
Inside site
, Widespread(15-50%)
The area is important as a migration corridor for Argali (Ovis ammon) and Snow Leopard (Uncia uncia). The planned 65km long unpaved road through the northern part of the Uvs Nuur Basin from Mongun-Taiga (Tuva) to Kosh-Agach (Altai) would open year-round transport passage (Tyvaavtodor, 2018). It may lead also to irreversible transformation of sensitive high mountain ecosystems. There would be an increase in cargo and passenger traffic and therefore potential human pressure in view of wildlife disturbance and poaching (IUCN, 2020b).
Mining & Quarrying
(Potential mining exploration in the buffer zone)
Outside site
In the beginning of 2019, information emerged that a company Resource Ltd. Co. from the Republic of Buryatia applied for a license for geological exploration and chrome ore mining on the Agar-Dag ridge in the buffer zone of the Yamaalyg cluster. The Department for Mineral Resources in the Central Siberian District (Tsentrsibnedra) requested permission from the reserve’s management for geological exploration, study, prospecting and assessing chrome ore deposits in the Uvs-Nuur basin.
The scientific and technical council of the reserve unanimously decided not to grant such a permission, noting that geological exploration and development of the deposit could lead to environmental degradation of the Agar-Dag ridge. In addition, part of this site is a sacred natural territory for the local population, and geological work here would violate the traditional principles and customs for caring for sacred natural territories (IUCN, 2020c).

Changes in Temperature Regimes, Changes in Precipitation & Hydrological Regime
(Climate change)
Inside site
, Extent of threat not known
Outside site
The rise in annual temperature and occurrence of consecutive dry years might cause increased risk of forest and steppe fires, as well as desertification, which ultimately may pose a threat to the OUV of the site (IUCN, 2013). In their reconstruction of climate change in the Altai mountain region west from the Uvs Nuur Basin, Ganyushkin et al. (2018) showed that the landscape, glaciers and forests have reacted sensitively to environmental changes. The glaciers of the Altai Mountains are estimated to have receded by over 40% in reaction to increasing summer temperature trends in the last 30 years (Pan et al., 2017). During the last two decades, global warming and extreme drought (in combination with soil degradation, aeolian processes and overgrazing) have caused an almost 5 times increase in the area covered by sand, having a profound effect on the Uvs Lake Basin ecoregion (Jamsran et al., 2019). Climate change may have impacted past lake-level fluctuations in the Uvs Nuur Basin (Walther et al., 2020), but there does not seem to be irreversible damage to the property’s integrity (The Government of the Russian Federation and the Government of Mongolia, 2001).
Recreational Activities
(Tourism pressure)
Inside site
, Localised(<5%)
Tourism does not pose a significant pressure on Uvs Nuur Basin. Although the number of domestic and international visitors has increased in some World Heritage component areas such as Tore-Khol Lake and Uvs Nuur (lake) (IUCN, 2017; Walther et al., 2020), the research on tourism resources and capacity of the Uvs Nuur Basin undertaken in 2018, showed that the visitor numbers are still well within the carrying capacity of the site (IUCN, 2020a). The main threats are associated with pollution (littering as well as inappropriate waste management and insufficient water and sanitation management) (Walther et al., 2020). However, the opportunities for large-scale tourism in the Uvs Nuur Basin are currently very limited, due to its remoteness and lack of tourism infrastructure.
Involvement of stakeholders and rightsholders, including indigenous peoples and local communities, in decision-making processes
It has been noted that the management authority on the Russian side does not pay sufficient attention to the needs of local population wishing to generate income through their traditional ways of livelihood in the areas neighbouring to the site (Butorin, 2005). There seems to have been a general lack of cooperation with local self-government structures, and probably also with local inhabitants and resource users (IUCN, 2017; UNEP-WCMC, 2011). The park authority on the Mongolian part of the site is engaging local people in the conservation activities by allowing non-detrimental traditional use of natural resources. In addition, it is collaborating with local communities in the tourism development, by supporting traditional handicraft making of the local people for the sale to tourists. Since 2009, in partnership with the WWF Mongolia Programme Office, the Altai-Sayan Project, and the Climate Change Project, the “Community Development and Partnership” event has been organized annually at local levels. Community members are empowered and learning from each other. There are also some 30 volunteer rangers who work together on conservation activities, which is important for effective monitoring. Although there are some concerns in the Russian component parts, the relationship with local people on the Mongolian side seem effective.
Legal framework
The basis for legal protection of protected areas that form part of the World Heritage Site include the Law on Special Protected Areas (1994) and the Law on Buffer Zones (1998) in the case of Mongolia, and the Federal Law on Special Protected Areas (1995) in the Russian Federation (The Government of the Russian Federation and the Government of Mongolia, 2001). The five Tuvan cluster areas making up the Ubsunorskaya Kotlovina (Ubsunuur Hollow) Nature Reserve in the Russian Federation were given protected area status by both the governments of the Republic of Tuva and the Russian Federation in 1993. In 2000, two clusters were added, expanding the territory of the protected area ("Kara-Khol" and "Khan-Deer", covering Snow Leopard habitats).
Governance arrangements
The protected areas in both countries are governed by the Ministry of Natural Resources of the Russian Federation and the Ministry for Nature and the Environment of Mongolia. Transboundary cooperation has been enabled through the provisions of the World Heritage Convention, the Agreement between the Governments of Mongolia and the Russian Federation on Cooperation in the Field of Environmental Protection (1994), the Ulaanbaatar Declaration (2000), and diverse relevant agreements between the Government of the Republic of Tuva of the Russian Federation and administrations Ubsu-Nur and Zavkhan aimags of Mongolia (UNESCO, 2022). In 2011, the two countries established the Russian-Mongolian Joint Commission for the Management of the Uvs Nuur Basin Transboundary Reserve, a high-level decision-making body responsible for the planning and evaluation of activities in the transboundary Biosphere Reserve (World Heritage Site is part of it) (UNESCO, 2022). According to the latest periodic report, coordination between the administrative bodies could be further improved (States Parties of Mongolia and the Russian Federation, 2023).
Integration into local, regional and national planning systems (including sea/landscape connectivity)
On the Russian side, the nature reserve is poorly integrated into the regional programmes (socio-economic, conservation and educational). Although in connection with the expansion of the reserve in 2000 (new clusters "Kara-Khol" and " Khan-Deer" covering Snow Leopard habitats were created), the reserve's office was transferred to Kyzyl, the capital of the Tuva Republic, a point equidistant from all clusters and district inspections. Located in Kyzyl, the reserve has improved its interaction with the authorities and public organizations (IUCN, 2020b).
Boundaries
Park boundaries are marked at the main entrance points with signboards. Back in 2005, the participants of the workshop on the “Management problems and development perspectives of the Uvs Nuur Basin World Heritage Site” noted that in the Tuvan side, the boundaries of the site were not well marked (Butorin, 2005). In order to develop the natural conservation management, ”border columns” and information boards have been set up in the strictly protected areas (IUCN, 2020). There is an agreement between Mongolian and Russian parts of the site to conduct joint inspection along both sides of the frontier, exchanging information on law infringement (Butorin, 2005).
Overlapping international designations
In 1997, the two Uvs Nuur nature reserves have been designated as UNESCO Biosphere Reserves in Mongolia and the Russian Federation, followed by proclamation of a single Uvs Nuur Basin transboundary Biosphere Reserve in 2021. The Mongolian Lake Uvs and its wetlands is a Ramsar Site, designated in 2004. Additionally, in Mongolia, Uvs Nuur with its surroundings is an Important Bird Area (MN009), and part of the East Asian Australian Flyway Network (EAAF130) (WWF Mongolia/Mongolian Protected Areas, 2022). The basin has been recognized by WWF as one of 200 Global Priority Ecoregions. The extent to which the management of the overlapping designations is effective could not be comprehensively assessed.
Implementation of World Heritage Committee decisions and recommendations
The 27th Committee decisions and recommendations focused on (1) upgrading the Tes River Specially Protected Area in Mongolia, protected at a provincial level at that time, to a Specially Protected Area under State legislation, which has since been implemented (World Heritage Committee, 2014); and (2) encouraging States Parties to ensure adequate resources made available quickly and maintained for the effective implementation of the management plans - this seems to have not fully been addressed yet (IUCN, 2017). No more recent decisions have been made.
Climate action
Monitoring of climate change is carried out regularly at scientific stations (The Government of the Russian Federation and the Government of Mongolia, 2001). At the site level rainwater and snow water are accumulated to form ponds, and in order to reduce desertification and increase green space, seedlings of water-retaining plants have been tested (States Parties of Mongolia and the Russian Federation, 2023).
Management plan and overall management system
Uvs Nuur Basin (898,064 ha) is a transnational serial property consisted of formally protected public lands in both countries, Mongolia and the Russian Federation (World Heritage Committee, 2014). The property consists of twelve components. Seven components are in the Russian Federation and form part of Ubsunur Hollow Nature Preserve, while five components are in Mongolia and form part of Uvs Nuur Nature Preserve (World Heritage Committee, 2014; UNEP-WCMC, 2011; The Government of the Russian Federation and the Government of Mongolia, 2001). The Mongolian part is a strictly protected area (IUCN protected area management category Ib) and covers almost half of the surface area of the entire property (UNEP WCMC, 2024; World Heritage Committee, 2014). There is no buffer zone in the Mongolian territory, but about 170,00 ha in the Russian Federation form the property’s buffer zone (World Heritage Committee, 2024). The two protected areas are managed by the respective countries’ park administrations (the Russian protected area falls under the Tuvan Ministry of the Environment). Protected areas are governed by the respective ministries of the two countries. Sacred natural objects located in the basin benefit from the protection by local communities (Uvs Nuur, Tore-Holl, Tsagaan-Khairkhan, Turgen, and others) (The Government of the Russian Federation and the Government of Mongolia, 2001). The management plan for the Tuvan section (Russian Federation) was approved in 2007 and covered the period of 2008-2012. It is not clear if a new management plan was developed and approved since. The latest management plan for the Mongolian section was developed and approved in 2019, covering the period from 2020 to 2024 (UNEP-WCMC, 2024; IUCN, 2020a). A first joint transboundary management plan was approved by both Governments in 2010, followed by an update approved in 2018, covering the period of 2018-2022. The plan provides an overview of essential ecosystems, communities (lakes, steppes, glaciers) and species and management based on the conservation strategy of guarding the territories, expansion of species' migration corridors, education and awareness raising activities, development of scientific research and monitoring, as well as the development of ecotourism (Ubsunurskaya Kotlovina State Biosphere Reserve, 2020).
Law enforcement
Detailed information on enforcement effectiveness; such as on the number of violations detected and brought to court, long term statistics in infringements, and similar, is not available. According to the website of the Russian component protected area, there is a lack of equipment for effective enforcement in some of the remote component areas of the series in Tuva Republic (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017). The geographical distance of the administration from the component areas, as well as the high staff turnover and lack of qualified staff have also been noted (IUCN, 2017) and are likely to limit enforcement effectiveness. It has been reported that weak enforcement capacity in combination with increasing visitation (at least on the Russian side) has led to an increase in poaching (IUCN, 2017). There are also concerns about illegal logging in some areas of the property (World Heritage Committee, 2014). Recently, stricter penalties for environmental crimes, joint inspections, as well as better advocacy and monitoring have been implemented to combat illegal activities (IUCN, 2020a), however, some concern regarding law enforcement still exist. According to the latest periodic report illegal hunting, logging, and violations of natural resources have been stopped as law enforcement improves. One ranger of the World Heritage site conducts 36 patrols and inspections per year, and specialists of the administration 24 times a year (States Parties of Mongolia and the Russian Federation, 2023).
Sustainable finance
Due to the small state budget for conservation work, the protected area management authorities with international and domestic environmental projects and programmes (IUCN, 2020). However, there are no up-to-date figures available on the annual budget of the reserves in any of the recent documents (IUCN, 2017; Ubsunurskaya Kotlovina State Biosphere Reserve, 2017; UNEP-WCMC, 2011; World Heritage Committee, 2014). This makes it difficult to assess the sustainability of current financing levels. However, there is concern because the high number of clusters that are remote requires effective transport and communication devices (Butorin, 2005). Lack of investment into the infrastructure can negatively impact the monitoring and protection activities of the park administration (IUCN, 2013). In addition, the website of the Tuvan component protected areas states that there are resourcing shortfalls on equipment, infrastructure and salaries (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017), which suggests that the financing level is not fully sustainable in the long-term.
Staff capacity, training and development
The reserve on the Tuvan side of the World Heritage site had 83 employees in 2013. The remoteness of the site and the high cost for travel to the training centres limit professional training and capacity building of site managers and staff although some programmes are ongoing (States Parties of Mongolia and the Russian Federation, 2023). Furthermore, the low level of remuneration for the park staff negatively influences the quality of their performance, leads to high staff turnover and hence to frequent losses of experienced staff (IUCN, 2013; IUCN, 2017; Ubsunurskaya Kotlovina State Biosphere Reserve, 2017). The size of the area monitored by each ranger is very large (between 7,500 and 22,000 ha per ranger) (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017). This discourages rangers to be committed for a long term (Enkhtsetsteg, 2009). Some trainings have been organized twice a year for the protected areas administration specialists, rangers and volunteer rangers (IUCN, 2020) and although overall the training programme was considered satisfactory in 2014, it needs to be further improved with the integration of new subjects on monitoring, research, GIS and remote sensing. Uvs Nuur Basin SPA administration has been paying particular attention to its staff development through providing external training at training institutions (Enkhtsetseg, 2009). Overall, the human capacity could be further improved but is considered adequate to protect the OUV (States Parties of Mongolia and the Russian Federation, 2023).
Education and interpretation programmes
In Mongolia, the environmental information centre is working with the aim to provide local population and visitors with the information on nature conservation, scientific literature and legislative acts. Educational programmes are broadcasted regularly through local and national TV and radio. Roundtable discussions are organized with the involvement of scientists, researchers and protected area staff. Annual events such as visits to the most prominent spots in the site, consultation with the local communities and environmental action days are organized in order to raise public awareness on the site’s protection (IUCN, 2013). In the Natural Heritage transition zone, training and advocacy for 7,500 people annually has been organized through four information centers and 14 school Eco-clubs, to disseminate environmental information, support Eco-club teachers and students in the suburbs, to provide opportunities for them to learn from each other and to improve their ecological education. Currently, over 500 children and teachers have taken part in the activities. The Uvs Nuur Basin has participated for the third year in the "Land of the Snow Leopard" festival which is organized by the Tuva Biosphere Reserve (IUCN, 2020a; UNESCO, 2022). The website of the Russian component protected area lists a range of education and awareness raising activities (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017). However, several reports refer to the fact that, overall, the awareness of the local population on environmental issues particularly on the transboundary biodiversity conservation, landscape and water conservation (IUCN, 2013) and ecological knowledge remains low (Butorin, 2005). It has also been noted that, on the Tuvan site, there is a need for closer integration of education and awareness raising activities with those of other local and regional players (IUCN, 2017).
Tourism and visitation management
Although the World Heritage Site includes a variety of places representing diverse natural landscapes and historic importance and has a great potential for eco-tourism, its recreational resources are underutilized (IUCN, 2013). The tourism does not generate tangible benefits and income for local people and protected area management. Furthermore, there are no statistics and related information on the number of visitors, main tourist routes and possible impact caused by the visitation. It also appears that there is localized and unregulated tourism pressure in some areas, such as Lake Tore-Khol in the protective zone of “Tsuger Els” cluster, and that unregulated dirt roads are appearing in steppe and sandy areas along Tes-Khem River (IUCN, 2017). This points to a potential need for more systematic and proactive tourism management.
Sustainable use
Local people are allowed to carry out non-detrimental traditional use of natural resources, particularly through grazing. Land use and waste management agreements have been set up with the households and livestock farmers in the transition areas of the site, which are evaluated once a year (IUCN, 2020). However, there is a need to regulate this more pro-actively (World Heritage Committee, 2014). Overgrazing seems to be evident in some areas, as a result of abandonment of nomadic lifestyle (The Government of the Russian Federation and the Government of Mongolia, 2001). It has also been noted that there is a rise of harvesting of non-timber forest products in the region (IUCN, 2017), which also suggests a need for a more systematic, regulated approach. Altai Onion (Allium altaicum) and some other valuable medicinal and food plants are being illegally harvested in larger quantities, however, this is occurring very locally (The Government of the Russian Federation and the Government of Mongolia, 2001). There is no information about the current situation in that regard.
Monitoring
Since 1997, Uvs Nuur Basin has been one of the International Geosphere-Biosphere Programme study areas. This programme conducts scientific research to monitor and understand global change, as well as into wetlands and wildlife (UNEP-WCMC, 2011, World Heritage Committee, 2014). This has been coordinated by the Ubsunur International Centre for Biospheric Research guided by the Siberian branch of the Russian Academy of Science (UNEP-WCMC, 2011). Both reserves’ authorities carry out monitoring activities on their respective territories (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017; World Heritage Committee, 2014; IUCN, 2017). However, no details are available on these monitoring programmes. Consultation reveals that the park administration lacks the adequate use of modern monitoring devices that include camera traps, genetic certification, GIS and remote sensing that are required for the monitoring of rare and endangered species (IUCN, 2013). Furthermore, there is a need to exchange research and monitoring/assessment data on transboundary endangered and migratory wildlife species, but progress in this direction has been slow in the past, due to lack of funding (Enkhtsetsteg, 2009). One exception is the joint transboundary Argali study that started in 2008. The population size is estimated during mating season, newborn Argali are captured, collared and telemetry surveys conducted. Results show that Argali populations in the transboundary area are doing well, with seasonal migration between Russia and Mongolia. In 2019 under an agreement with the Border Guard Office for the Republic of Tuva and the Ubsunur Basin reserve, barbed wire fences on the Argali migration routes were dismounted. However, there is a need for resources, capacity and involvement of local conservation communities to address negative factors on virgin high mountain ecosystems, degradation of pasture, infrastructure development, highway construction, illegal hunting and mining activities (IUCN, 2020a).
Research
The basin has an exceptional scientific importance because of its relatively pristine conditions. Research activities have been ongoing for decades, while in 1984, an ”Ubsunur Experiment” international programme was launched. The programme has been gathering specialists from diverse disciplines, such as biology, geography, soil sciences, mathematics, economy, history and other, to study the area using satellite information and mathematical modelling (UNEP-WCMC, 2011; The Government of the Russian Federation and the Government of Mongolia, 2001; UNESCO, 2022). Every two years since 1989, the two protected areas’ administrations have been co-organizing the "Uvs Nuur" international symposia “Ecosystem of Central Asia: Research, Conservation and Sustainable Use”, leading to relevant recommendations, declarations, and actions to be taken (IUCN, 2020a; The Government of the Russian Federation and the Government of Mongolia, 2001). The programme enabled the development of three major publications and 12 research projects into glaciers, soils, ecosystems and rare animals (UNEP-WCMC, 2011). Some research activities have been undertaken with the support of WWF and UNDP, and in cooperation with a range of research institutions predominantly in Russia (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017). There is also scientific cooperation between the Russian and Mongolian protected areas and their partners. Joint research on snow leopards in transboundary areas started in 2010. Migration and gene flow are important to keep the populations healthy, especially for the small Russian population at the northern edge of the world’s snow leopard distribution area. Results show that snow leopards migrate between Mongolia and Russia crossing the Asgat River (IUCN, 2020a; Мunkhtsog et al., 2015). Since 2017, 39 surveys of rare insects, reptiles, birds, and plants, as well as climate change and glaciation studies have been conducted in the Uvs Nuur Basin. These include: Snow Leopard, Argali, Ibex, Beaver, Siberian Sparrowhawk, Central Asian Beaver, Reed Pig, River Otter, Altai Snowcock, Musk Deer, Mongolian Marmot and plant research (IUCN, 2020a; UNESCO, 2022).
Effectiveness of management system and governance in addressing threats outside the site
Mongolia’s most important natural resource is its grasslands, and the most important threat from outside the World Heritage site is the continuously increasing stock numbers leading to overgrazing (IUCN, 1999). Since Mongolia privatized grazing herds in 1992, there has been a spectacular increase in the number of domestic livestock population from 20 million in 1992 to 40 million in 2010. However, according to a livestock census at the end of 2019, there are no households in the core and buffer zones of the World Heritage Site, and in the transition zone there are 232,688 livestock from 692 households (IUCN, 2020a). Managing livestock grazing is a key issue in maintaining the integrity of the natural and cultural values of ecosystems of Uvs Nuur, although its direct impact at the level of the property is unclear and in need of further study. Some limits to effective law enforcement have been noted, including lack of equipment, geographical distance between the administration and component areas, as well as the high staff turnover and lack of qualified staff. The size of the area monitored by each ranger is also very large (between 7,500 and 22,000 ha per ranger, depending on PA category). This could compromise the management of threats from, for example, illegal logging, poaching and forest fires.
Effectiveness of management system and governance in addressing threats inside the site
Formal protected area management effectiveness assessments were performed in 2005 and 2012 for the Mongolian protected area, and in 2012 for the Russian site, but there are no more recent assessments (UNEP-WCMC, 2024). The administration of the Russian reserve listed some issues related to the legal basis (particularly financial and legal obligations of land users), a lack of equipment of the protection service (vehicles, communications equipment, office equipment, uniforms and field clothing), a high staff turnover and low wages, and lack of qualified staff as factors limiting management effectiveness (Ubsunurskaya Kotlovina State Biosphere Reserve, 2017). Such situation imposes challenges in managing certain threats to the property such as poaching, illegal logging, or efficient management of visitors. It has also been noted that the geographical distance of the administration (based in the Kyzyl, the capital of the Tuva Republic) from the actual component areas, compromises effective management, but at the same time enables close relations with other public institutions. Transboundary cooperation seems to be well established, particularly through the Joint Commission for the Management of the Uvs Nuur Basin Transboundary Reserve whose members meet regularly. One of the important transboundary cooperative activities was temporary opening of the barriers at the state border in the Mongun-Taiga district of Tuva to allow seasonal migrations of Argali. This major achievement required more than a decade of negotiations and helped stabilize the Argali population on the Russian side (UNESCO, 2022).
The Governments of both Mongolia and Russian Federation are providing significant support to the protection and management of this transnational serial site through an enabling legislative environment and some financing. Regional and provincial governments are also involved in the landscape and biodiversity conservation, even if cooperation has been characterized as weak. The site has a joint management plan, but implementation has previously fallen short of expectations due to budget and staff constraints, and has been dependent on additional funding from donor organizations. Some threats such as overgrazing, particularly in the desert steppe landscape around Uvs Nuur, do not seem to have adequate response from the management authorities. Although aspects such as the legal framework, boundaries, relationships with local people and education and interpretation programmes are mainly effective, there is some concern with other aspects highly important for the protection and management of the site, such as the management system and its effectiveness, as well as the integration into regional and national planning systems, law enforcement, staff training and development, and sustainable finance.
Good practice examples
Transboundary collaboration: The first joint initiative between Russian and Mongolian scientists and conservationists was the “Ubsunur Experiment” survey (1984 – 1988) and the first joint scientific conference was organized in 1989. Since then, many joint research projects, international scientific conferences and conservation work have been carried out, and as a result of joint efforts by the both countries' Governments, researchers, and conservationists, this collaboration is expanding year by year (IUCN, 2020a).
Diversity of landscapes, ecosystems and habitats
Low Concern
Trend
Deteriorating
Although it is difficult to predict, increase in the annual temperature might be increasing overall dryness of the area. The process of desertification is gradually shifting from west to east on the Mongolian part of the Uvs Nuur Basin site and starts spreading to areas not previously covered by sand. In a recent study of land cover change in the Uvs Lake Basin, Jamsran et al. (2019) found that over the last two decades there has been an almost 5 time increase in the area covered by sand. Overgrazing in Mongolia, and possibly the Russian Tuva Republic, and the agriculture development through intensive use of water irrigation and conversion of natural areas into crop plantation on the Russian side could change the hydrological regime of the lakes (Anomymous, 2010). Some small areas have been affected, primarily by inadequate waste management, by uncontrolled visitation (IUCN, 2017). Since 2017, 39 surveys of rare insects, reptiles, birds and plants, as well as climate change and glaciation studies have been conducted in the Uvs Nuur Basin (IUCN, 2020).
Threatened and endemic plants
Data Deficient
Trend
Data Deficient
The problem of overgrazing, disappearance and melting of glaciers, overall dryness in the area and lowering of water level of rivers and streams due to climate change effects are assumed to change the vegetation structure of the area. The situation is likely exacerbated by the anthropological impacts such as illegal artisanal mining, diverting rivers for agriculture use, removal of topsoil for reforestation and gardening activities in the cities and excessive extracting of medicinal plants (Compilation of Research Work, 2011). However, due to the insufficient research data it is difficult to assess the current state of the value.
Rare and threatened bird species
Data Deficient
Trend
Data Deficient
There are no available systematic bird monitoring data to analyze bird population status and trends, but there is also no evidence of any population decline of bird species and any concern and major problem raised by the park management and/or research communities.
Rare and threatened mammals
Low Concern
Trend
Deteriorating
Since 2017, surveys of snow leopard, argali, ibex, beaver, reed pig, river otter, musk deer and Mongolian marmot have been conducted in the Uvs Nuur Basin. The Snow Leopard (Uncia uncia) population was estimated to 62 individuals in 2019. Joint monitoring of the transboundary Argali (Ovis ammon) population is undertaken once every two years. The last survey showed that there are 1794 Argali sheep in Uvs province, and a total of 4555 individuals in the transboundary area (IUCN, 2020). However, there is evidence of illegal hunting of Argali, recorded on the Mongolian part of the site. Furthermore, decrease of the habitat area due to overgrazing and competition for pasture with the domestic livestock has taken its toll on the population growth of Argali. It is likely that this also affects other ungulates and potentially even predators. It is unclear if this should be considered of low or high concern overall, but because of the large area and low population density of the property, the former is chosen as the assessment category, although the trend is perceived as deteriorating.
Other rare and threatened fauna

Data Deficient
There is no detailed information about the current conservation state of herpetofauna, entomofauna and ichthyofauna inside the property.
Assessment of the current state and trend of World Heritage values
Data Deficient
The unique climatic and hydrological regime of the Uvs Nuur Basin might ultimately be affected by on-going climate change process and overall dryness in the area. While more scientific data would be needed to predict changes in the landscape and hydrological regime, climate change has already caused significant glacial retreat and desertification. Though it is apparent that overgrazing greatly affects the vegetation growth and structure in the basin, there are no sufficient data to make any definite conclusions on the status of the endemic plants. There is no evidence of population decline and/or significant problem recorded for the rare and endangered species of the bird. Due to the large area and low population density of the World Heritage site, the overall state of rare and threatened mammals is currently of low concern, however, illegal hunting and continuous shrinking of habitat area for the endangered mammals in particular argali (wild sheep) is of some concern. Although the trend for some landscape habitats and mammals seems to be deteriorating due to desertification, overgrazing and water stress, the trend for plants and bird species is difficult to assess due to the insufficient data.
Additional information
Water provision (importance for water quantity and quality)
The site provides water source in the region for domestic use.
Sacred natural sites or landscapes
Due to their nomadic way of living Mongolian and Tuvan people have a strong linkage and dependence on nature. The World Heritage site includes sacred mountains, mountain passes and worshiped rivers and streams. The area provides a source of livelihood for local people and security, and also holds aesthetic and spiritual values for external people (World Heritage Commitee, 2014).
Outdoor recreation and tourism
The unique natural features, the presence of historical, cultural and archaeological monuments, a traditional nomadic lifestyle with its ethnographic peculiarities and traditional crafts provide an ample opportunity for development of various types of tourism. Cultural and ethnic tourism, hiking, trekking, mountaineering and bird watching are the main types of tourism currently developed in the region. There are multiple burial mounds and fields, deer stones, vertical memorial plates, man stone effigies, rock paintings (petroglyphs) and ancient human camps (IUCN, 2003; World Heritage Committee, 2014; IUCN Consultation, 2017).
Collection of wild plants and mushrooms,
Livestock grazing areas
The area is used for extensive traditional grazing, as well as the collection of non-timber forest products (World Heritage Committee, 2014).
Uvs Nuur basin provides considerable benefits to local people through water provision, grazing areas and forest resource collection. It has also huge spiritual and cultural importance to the local people on the Mongolian and Tuvan side and a great potential (as yet only partially fulfilled) to provide benefits related to recreation and tourism to a wider international range of stakeholders. These benefits may be – to different and not always fully understood degrees – subject to threats from overuse, land use change, and climate change.
