It is located in the Republic of Buryatia in Kurymkansky region. The reserve is unique due to its location in the eastern part of the northeast shore of Lake Baikal, where the three huge mountain ridges Barguzinsky, Ikatsky and south Myisky cross. The heart of the reserve is the delightful, sacred relic glacial hollow Amutskay, in which crystal clear lakes are located. The reserve area is 238,000 hectares; 0,894 thousand hectares are occupied by water. The Dzherginsky Nature Reserve occupies 19 % of the area of Kurymkansky region. Dgerginsky Nature Reserve was set up on August 14, 1992 with a total area of 238,700 hectares.

Baikalsky Nature Reserve is located in the Republic of Buryatia, stretching along the southern bank of the lake Baikal. It was founded in 1969 to cover the area of 1657 sq.km. It has a status of a biosphere reserve. It includes the central part of Khamar Daban Mountains, between the water mirror and the heights from 2000 to 2300 m above the sea level. Alpine reliefs, with their mountain circuses, canyons and pointed peaks dominate the highlands.
The northern slopes are covered by the dark coniferous (fir, spruce and cedar pine) taiga, or by sphagnum bogs and birch forests. The vegetation of the southern slopes consists of light coniferous (pine and larch) forests, while in the lowlands the steppe parcels are not unusual. A total of 68 % of the protected territory is forests. The vascular flora counts up to 812 species, of which 12 are enlisted in the Russian Red Data Book. The fauna of 49 mammal, 272 bird and 7 fish species are common for the southern mountain taiga.

Barguzinsky Nature Reserve is located in the northern part of Republic of Buryatia, on the North-Eastern shore of the lake Baikal. It was founded in 1916 and primarily aimed for the protection of sable (Martes zibellina). It covers the area of 3743 sq. km. It includes the western slope of the Barguzin Mountain Range with the highest peaks up to 3000 m above sea level. To 1111 sq. km the status of the Biosphere polygon was granted. The reserve borders the Zabaikalsky National Park in the south.
The total area covered by woodlands and forests is 2200 sq. km. The vascular flora of the reserve consists of 874 species, of which 7 are considered relic or endemic. Numerous hot springs (temperatures above 36°C, up to 76°C) by peculiar thermophilous plant communities.
The terrestrial vertebrate fauna is presented by 39 mammal, 260 bird, 4 reptile and 2 amphibian species.

Baikalo-Lensky Nature Reserve is located on the western shore of the lake Baikal, opposite the Bargusinsky Nature Reserve. It was founded in 1986 to cover the area of 6600 sq.km. It includes the upper basin of the River Lena and its tributaries - the Kirenga, the Tongoda, the Maly Anoy and Bolshoy Anoy. All these rivers begin in the Baikal Mountain Range. The nature reserve stretches along the Lake Baikal bank for 100 km.
Cedar, fir, larch and spruce prevail in the tree flora on the western slopes of the Baikalsky mountain range and in the lower dark coniferous forests.
The Reserve's vascular flora consists of more than 800 plant species; 27 of them are rare and were included into the Red Data Book. 48 mammal species and 171 bird species have been registered at the territory of the Reserve.

Zabaikalsky National Park was established in 1986 and is situated on the eastern shore of Lake Baikal in the Barguzinsky District in central Republic of Buryatia. The park includes the western slopes of the southern Barguzin Mountain Range, Syatoy Nos Peninsula, Ushkani and Chivyrkuisky islands, and Chivyrkuisky and Barguzin Gulfs. To the north, the park borders the Barguzin Nature Reserve.
Wildlife in Zabaikalsky National Park is made up primarily of taiga faunal communities. There are 291 terrestrial vertebrates in the park, including 44 mammals, 241 birds, three reptiles, and three amphibians. Plant communities in the park are distributed according to vertical zoning along the mountainous terrain. The bottom belt of forests is primarily made up of larch forests with an undergrowth of mountain pine. Mixed pine (P. sylvestris, P. sibirica) and larch forests occupy areas higher up. From 1400-1500 m above sea level, mountain tundra ecosystems, alpine meadows, and rocky slopes dominate the terrain.
There are a number of historical and cultural monuments in the national park. Archeological sites of interest in the park include camps from the Neolithic era, tombs from the second century b.c., tombs of nomads from the XIV-XV centuries, traces of an ancient irrigation system, and 35 settlements from the Bronze and early Iron ages.

The Tunkinsky National Park is located in the Republic of Buryatia. It was established 1991 to cover an area of 1,183,662 hectares. It occupies the Tunkinsky Valley with the adjacent mountain ridges of the Eastern Sayans and Khamar-Daban.
Absolute heights range from 668 m to 3172 m above sea level. Siberian cedar, larch and pine forests prevail in the forest altitudinal belt, higher they are changed by krummholz thickets.
The tops of the highest mountains and ridges are covered by mountain tundra and alpine glades.
At present there are more than 310 kinds of the vertebrate animal referring to 5 classes, including - fishes (more than 10 species), amphibious (more than 4 species), reptiles (5 species), birds (237 species), mammals (54 species). 150,836 hectares from the whole territory are in agricultural use. The Tunkinsky National Park is well developed; alarge part of the Tunkinsky Valley is cropland, hayfields and pastureland. The Tunkinsky Valley is famous for its mineral springs. Among the most famous are Arshan, Nilova Pustyn and Zhemchug mineral springs health resorts.

It was developed in 1986. The park is spreading for about 350 km along the southwestern coastline of the Baikal lake, from Kultuk settlement to the river Kheiren. It includes the whole of the island of Olkhon and covers 4180 sq.km of the slopes of the Primorsky range overlooking the lake (the maximum altitude within the park is 1707 m above the sea level and 1250 m above the lake level). 85 % of the park are under the forests.
380 species of vertebrates are registered in the park fauna. Among them are 59 mammal species, 272 bird species, 6 species of reptiles, 3 amphibious species and, finally, 40 fish species.
Several thousand birds (over 10 thousands certain years) stay for winter in the mouth of the Angara as it does not freeze. This is most unusual for Siberia.

In the park there have been determined 54 natural monuments, of them 22 geological, 2 botanical, 10 zoological, 8 aquatic and 12 are combined monuments.
