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.
In the north of the region is the Sailughem Mountains, also known as Kolyvan Altai, which stretch northeast from 49° N and 86° E towards the western extremity of the Sayan Mountains in 51° 60' N and 89° E. Their mean elevation is 1,500–1,750 m (4,920–5,740 ft).
The Sayan Mountains' towering peaks and cool lakes southwest of Tuva give rise to the tributaries that merge to become one of Siberia's major rivers, the Yenisei River, which flows north over 3,400 kilometres (2000 mi) to the Arctic Ocean. This is a protected and isolated area, having been kept closed by the Soviet Union since 1944. [3]
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.
The Sayan Alpine meadows and tundra ecoregion (WWF ID: PA1016) is an ecoregion that covers the high areas of the Sayan Mountains above the treeline, between the Altai Mountains in the west and Lake Baikal in the east. The area is remote and protects diverse species of alpine flora and fauna.
Altai is located in the Sayan montane conifer forests ecoregion. This ecoregion is characterized by mountains dissected by river valleys, high levels of precipitation, and high biodiversity. This ecoregion is characterized by mountains dissected by river valleys, high levels of precipitation, and high biodiversity.
Altai Mountains, Sayan Mountains and Khangai Mountains. Mongolia has four major mountain ranges. [2] The highest is the Altai Mountains, which stretch across the western and the southwestern regions of the country on a northwest-to-southeast axis. [2] The range contains the country's highest peak, the 4,374 m (14,350 ft) high Khüiten Peak. [2]
The Sayan montane conifer forests ecoregion (WWF ID: PA0519) covers the mid-elevation levels of the Sayan Mountains, the high mountain range between the taiga of Siberia, Russia to the north, and the steppes of Mongolia to the south. The slopes of the mountains at the mid-altitudes are covered by Temperate coniferous forest.
