The Altai-Sayan region is an area of Inner Asia proximate to the Altai Mountains and the Sayan Mountains, near to where Russia, China, Mongolia and Kazakhstan come together. This region is one of the world centers of temperate plant diversity. Its biological, landscape, historical, cultural and religious diversity is unique. 3,726 species of vascular plants are registered in the region including 700 threatened or rare species, 317 of which are endemic; fauna consists of 680 species, 6% of which are endemic. Its ecosystem is comparatively unchanged since the last ice age, and it is the host of endangered species that include the saiga, nerpa, and snow leopard. It is the focus of ongoing international and regional environmental conservation initiatives.
The area is also culturally diverse, with four language groups (Slavic, Mongolic, Sinitic and Turkic, formerly Samoyedic and Yeniseian as well) and more than 20 indigenous ethnic groups practicing traditional land use systems. There are also a variety of religions including Christianity, Islam, Buddhism, Tengrism and Shamanism. The region covers more than one million square kilometers, and has a population of between 5 and 6 million inhabitants. [1]
The Altai-Sayan ecoregions contain and share a name with the Altai Mountains and the Sayan Mountains. The Altai Mountains are a mountain range in East-Central Asia, where Russia, China, Mongolia and Kazakhstan come together, and are where the rivers Irtysh and Ob have their headwaters. The Sayan Mountains lie between northwestern Mongolia and southern Siberia.
The Altai-Sayan has a total area of 1,065,000 square kilometers. Its area belongs to the territory of Russia (62%), Mongolia (29%), Kazakhstan (5%) and China (4%). [2] : 233
Part or all of the Russian oblasts of Kemerovo, Novosibirsk, and Irkutsk; the Krais of Altai and Krasnoyarsk; and the Autonomous Republics of Altai, Khakassia, Tuva, and Buryatia lie within the Altai-Sayan, as do parts of the Ili Kazakh Autonomous Prefecture of China's Xinjiang Uyghur Autonomous Region, East Kazakhstan province of Kazakhstan, and the Mongolian Aimags of Govi-Altai, Khovd, Bayan-Ölgii, Uvs, Zavkhan, and Khövsgöl.
At the far north of the Altai-Sayan region, near its boundary, is the Russian city of Krasnoyarsk (population above 900,000 in 2010 census). [2] : 233 Other towns in the region include Kyzyl in Russia (pop. about 110,000 in 2008), as well as Ulaangom, Ulgii, and Khovd, all in Mongolia (each with population under 30,000). [2] : 233 The Russian town of Gorno-Altaysk (pop. about 60,000 in 2010) lies within the region near its western boundary, and the Russian city of Irkutsk lies just outside the region to its east. [2] : 233 The Altai-Sayan region's total population is estimated as about 5.5 million. [2]
Contained within this ecoregion is the Great Lakes Hollow, a large semi-arid depression, bounded by the Altai in the West, Khangai in the East and Tannu-Ola Mountains in the North. [3] This contains six major lakes: the saline lakes Uvs Nuur, Khyargas Nuur and Dörgön Nuur; and freshwater lake Khar-Us Nuur, Khar Nuur and Airag Nuur. These are remnants of the West Siberian Glacial Lake, a periglacial lake formed when the Arctic Ocean outlets for each of the Ob and Yenisei rivers were blocked by the Barents-Kara Ice Sheet during the Weichselian Glaciation, approximately 80,000 years ago. [4]
According to Anatoliy Mandych, a geographer at the Russian Academy of Sciences (see also WWF [5] ),
For many centuries, the region has been at the crossroads of European and Asian civilizations, and thus is home to great historical treasures. The ancient history of the region is so unique that many historians and archaeologists call it “the cradle of civilization”. The ancient historic monuments are integrated into the natural landscape in such a way that it forms a harmonious and inseparable unity. Thousands of petroglyphs, cave paintings, antique burial mounds, menhirs, steles, tumuli and other ancient monuments are found in the area, some even as ancient as the Egyptian pyramids. [2] : 235–6
Altai-Sayan is home to the Denisova cave, famous for the 2010 discovery of 50,000-year-old fossils of a new kind of human, the Denisovans. Since then, Neanderthal bones, and tools crafted by Homo sapiens have been found in the cave. This makes it the only place where all three hominins have been known to live. Conditions in the Altai-Sayan are stable, so ancient humans may have taken refuge there during glacial interchanges and lived off the diverse game species. [6] Malaya Syya in Khakassia, another ancient archeological site in the region, has been dated to 35,000 BCE. [2] : 236 [7]
Recent genetic studies have shown that some indigenous peoples of the Americas are partially derived from southern Altaians. [8]
According to the New Scientist , the mix of mammals in the Altai-Sayan region has been among the least changed since the last ice age, in comparison to the mammalian population of any other region on earth. Its stability over time suggests that it may have acted as a refugium for mammoth steppe fauna both during and between ice ages. [10] [ better source needed ]
There are three major UNESCO World Culture and Natural Heritage Sites in the ecoregion – the Golden Mountains of Altai, consisting of the Altai and Katun Natural Reserves, Lake Teletskoye, Belukha Mountain, and the Ukok Plateau; Lake Baikal, which forms part of the eastern border of the region, and Uvs Nuur Basin in the Great Lakes Hollow.
The Great Lakes Hollow, in addition to its saline lakes, contains some of the most important wetlands of Central Asia. The wetlands are based on the system of interconnected shallow lakes with wide reed belts within the steppe. As a key part of the Central Asian Flyway, the wetlands support a number of rare and endangered migrating birds: Eurasian spoonbill ( Platalea leucorodia ), black stork ( Ciconia nigra ), osprey ( Pandion haliaetus ), white-tailed eagle ( Haliaeetus albicilla ), swan goose ( Cygnopsis cygnoides ), bar-headed goose ( Anser indicus ), and white pelican Pelecanus onocrotalus . [11]
The World Wildlife Fund has conducted studies of the region. [2] It has identified the Altai-Sayan ecoregion as a priority region for wildlife conservation. [12] According to the World Wildlife Fund, "The Altai-Sayan ecoregion is one of the last remaining untouched areas of the world." [12] Furthermore:
680 species of the vertebrates are registered in the Ecoregion. Among them: 77 species of fishes, 8 species of amphibians, 25 species of reptiles, 425 species of birds and 143 species of mammals. [12]
Threats to the biodiversity of the region, according to the Fund, include poaching and illegal wildlife trade, industrial development, climate change, overgrazing and competition for pastures, unsustainable forestry, water pollution, and poverty. [12]
Beginning in the late 1990s, several government-level initiatives were begun with the stated purpose that included helping to preserve the Altai-Sayan ecoregion and biodiversity. In 1998, representatives of Kazakhstan, China, Mongolia and Russia met in Urumqi to organize a trans-boundary nature reserve and launch joint biodiversity conservation programs. [2] : 237 That same year, several republics in the Russian Federation (Tyva, Khakassia and Altai) also signed an environmental protection agreement. [2] : 238 Five years later, in March 2003,
organizations representing state governments of Altai Region (Russia), Bayan-Ulgii Aimag (Mongolia), Eastern Kazakhstan Region (Kazakhstan), the Republic of Altai (Russia), Xinjiang Uygur Autonomous Region (China) and Khovd Aimag (Mongolia) resolved to establish an International Steering Board called "Altai, Our Common Home" [2] : 238
However, as of 2010, the steering organization "Altai, Our Common Home" had played a coordinating role "less in conservation and ecological themes" than in "economic and cultural exchange programmes". [13] : 250 Analysts stated that "while the [ecosystem conservation] soil has been prepared for cultivation rather well", after 10 years "there are no tangible results yet". [13] : 250 They expressed concern that
At the 'grass roots' level, managers of transboundary protected areas were not involved in the process. The leading role was played by international NGOs and funders. Overall, the general concept was not clearly formulated and developed. [13] : 250
The Altai-Sayan region is the northernmost habitat of the snow leopard. [2] : 235 a species listed on the IUCN Red List of Threatened Species as globally vulnerable. [9]
The Altai-Sayan region, or phenomena associated with it, have been the focus of various types of science and scholarship in diverse fields:
The Altai Mountains, also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia, and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E.

It is the largest lake in Mongolia by surface area, covering 3,350 km2 at 759 m above sea level. The northeastern tip of the lake is situated in the Tuva Republic of the Russian Federation. The largest settlement near the lake is Ulaangom. This shallow and very saline body of water is a remainder of a huge saline sea which covered a much larger area several thousand years ago.
Uvs Lake Basin is an endorheic basin located on the territorial border of Mongolia and Tuva, a republic of the Russian Federation. The basin is part of the Central Asian Internal Drainage Basin and is named after Uvs Lake, a large saline lake situated in the western part of its drainage basin, and is one of the last remnants of the mammoth steppes. Uvs Lake is a shallow lake with an area of 3,350 km2 (1,290 sq mi). Its entire basin, which includes several smaller lakes, is 70,000 km2 (27,000 sq mi).

Bounded by the Altai in the West, Khangai in the East and Tannu-Ola Mountains in the North, it covers the area of over 100,000 km2 (39,000 sq mi) with elevations from 750 to 2,000 m (2,460–6,560 ft).
South Central Siberia is a geographical region in North Asia, just north of the meeting point between Russia, China, Kazakhstan and Mongolia.
The wildlife of Mongolia consists of flora, fauna and funga found in the harsh habitats dictated by the diverse climatic conditions found throughout the country. In the north, there are salty marshes and fresh-water sources. The centre has desert steppes. In the south, there are semi deserts as well as the hot Gobi Desert in the south, the fifth-largest desert in the world.
The Southern Siberian rainforest is an area of temperate rainforest in South Central Siberia that occurs primarily along the Altai and Sayan mountain ranges in Khakassia and Tuva as well as a small area in the Khamar-Daban Mountains near Lake Baikal in Buryatia. The forest encompasses a total area of approximately 6,000 square kilometres (2,300 sq mi). The larger portion of the forest in the Altai and Sayan Mountains runs across a latitude range that encompasses between 51.5 degrees to 56 degrees north latitude, and a longitude range running between 86 degrees to 95 degrees east longitude. The region overlaps with the Golden Mountains of Altai World Heritage Site. Ecological zones range from hemiboreal forest to a forest-steppe ecotone and include a wider variety of plant species than surrounding areas.
Saylyugemsky National Park sits at the mountainous "X" where the borders of Russia, Kazakhstan, Mongolia and China meet in the Altai Mountains of central Asia. Because of its remoteness and position at the meeting points of mountains, steppes, desert and forest, it is a globally important natural reserve for biodiversity. The park was formally established in 2010–2012, with a particular purpose of protecting the vulnerable Altai argali mountain sheep and the endangered Snow leopard. The component Saylyugem Mountains are a ridge of the Altai, and stretch to the northeast to the Sayan Mountains. The climate is cold and semi-arid. Administratively, the park is located in the Kosh-Agachsky District of the Altai Republic. While ecotourism has a stated role, visits to the territory currently require special passes from park administration, and activities are limited to roads and trails.
Khakasski Nature Reserve is a Russian 'zapovednik' covering two large mountain areas, and a cluster of seven steppe sites located within the left bank of the Minusinsk depression. The reserve is situated in the Tashtypsky District of Khakassia. It was originally created to preserve steppe ecosystems, wetlands and waterfowl nesting sites, and a historical complex of monuments and cemeteries from the 4-11 centuries BC. The reserve is particularly noted for its variety of large lakes on the Yenisei River migration route for birds. The current configuration of protected sectors was established in 1999, and covers a total area of 2,675.58 km2 (1,033.05 sq mi).
The Altai montane forest and forest steppe ecoregion covers patches of the subalpine forest belt on the Altai Mountains, crossing the border region where Russia, Kazakhstan, Mongolia and China meet.
