The Khangai Mountains conifer forests ecoregion (WWF ID: PA0512) covers the northern slopes of the Khangai Mountains in central Mongolia. The montane taiga supports a populations of elk, deer, wild boar, wolves, and brown bear. The diversity of plants and animals has benefited from the relative isolation and low human population of the area. [1] [2]
The ecoregion is small, only 100 km from west to east, and 25 km from south to north. It covers the northern ridges and valleys of the Tarvagatai Range of the Khangai Mountains, at elevations of 2,000–2,600 metres (6,600–8,500 ft). Stream valleys drain the slopes northward into the Ider River, which runs below the northern edge of the ecoregion. [3] [4] The northernmost slopes of Mongolia's Tarvagatai Nuruu National Park are in the ecoregion.
The climate of the ecoregion is Cold semi-arid climate (Köppen climate classification (BSk)). This climate is characteristic of steppe climates intermediary between desert humid climates, and typically have precipitation is above evapotranspiration. At least one month averages below 0 °C (32 °F). [5] [6]
The ecoregion is a thin band of taiga; the slopes above the valley floors are generally forested with Siberian larch (Larix sibirica) and Cedar. Large mammals include Red deer (Cervus elaphus), Siberian roe deer (Capreolus pygargus), and Wild boar (Sus scrofa). A portion of the ecoregion is now protected by the Tarvagatai Nuruu National Park.
Barguzinsky Nature Reserve is the oldest of zapovedniks, established in 1916 for the protection of the Barguzin sable. It is located in Buryatia (Russia) on the west slope of the Barguzinsky Range, including the northeast shores of the Lake Baikal and a part of the lake itself. The area of the reserve is 2,482 km2 (958 sq mi), covering several types of boreal ecosystems, from bogs and taiga coniferous forests to subalpine meadows and mountain tundras. The landscape is postglacial, featuring rugged highlands, long river valleys and outwash, alluvial and lacustrine plains.
Shushensky Bor National Park consists of two representative forests in the extreme southwest of Siberia, in the northern foothills of the Western Sayan Mountains. The northern section is forest-steppe in character, while the southern section is mountain conifer forest. The southern section is bordered on two sides by the Yenisei river reservoir behind the Sayano-Shushenskaya Dam, the largest hydroelectric dam in Russia. The forest has both high biodiversity value and recreational value for hikers and tourists. It is located in the Shushensky District of Krasnoyarsk Krai.
Zaybaykalsky National Park covers the middle section of the eastern shore of Lake Baikal, the west slope of the Barguzin mountains to the east, the Ushkany Islands, and the only large peninsula on the lake, Svyatoy Nos. Of the 2,690 km2 (1,040 sq mi) of the park, 38.8 km2 are protected water areas of the lake itself.
Zeya Nature Reserve is a Russian 'zapovednik' located over the mountainous headwaters of the Zeya River, on the eastern end of the Tukuringra Range, where it joins the Dzhagdy, in the Amur Region of the Russian Far East. It was created in part to serve as a "reference plot" for the study of the ecological impact of the Zeya Dam and the Zeya Reservoir which were built in the 1960s and 1970s. The ground cover in the reserve is primarily taiga, of mostly larch and Mongolian oak. The reserve is situated 13 km north of the city of Zeya, in the Zeysky District of Amur Oblast.
Sokhondo Nature Reserve is a Russian 'zapovednik' in the south of Eastern Siberia, 25 km north of the border with Mongolia. It is the farthest source of the Amur River, and is centered on the Sokhondo Mountain massif, in the highest sector of the Khentei-Chikoy Highlands in the Khentei Range mountain range. The Sokhondo massif has two peaks, and is an ancient volcano. Also within the borders are many lakes of glacial origin. In 1985, Sokhondo was named a UNESCO MAB Biosphere Reserve. The reserve is situated in the Chita district of Chita Oblast.
Nora Nature Reserve is a Russian 'zapovednik' on the northeastern part of the Amur-Zeya lowland plain between the Nora River and the Selemdzha River. The reserve is known for its herd of Norsk roe deer, the largest migrating herd in the world, with 5,000-7,000 individuals migrating through every September. The terrain is half forested, and half wetland and bogs, in the meeting zone between Siberian, Okhotsk, and Mongolian plant and animal communities. The reserve is situated in the Selemdzhinsky District of Amur Oblast.
The Transbaikal conifer forests ecoregion covers a 1,000 km by 1,000 km region of mountainous southern taiga stretching east and south from the shores of Lake Baikal in the Southern Siberia region of Russia, and including part of northern Mongolia. Historically, the area has been called "Dauria", or Transbaikal. It is in the Palearctic realm, and mostly in the boreal forests/taiga biome with a subarctic, humid climate. It covers 200,465 km2 (77,400 sq mi).
Sayano-Shushenski Nature Reserve is a Russian 'zapovednik' reserve in a remote area of the West Sayan Mountains of south Siberia. It is on the southern bank of the Yenisei River along the Sayano-Shushenskoye reservoir. The reserve thus protects a large section of the wooded, mountainous territory above the reservoir created by the Sayano-Shushenskaya Dam, the largest power plant in Russia. Both the reserve and the dam were established 1976, and a major purpose of the reserve besides conservation is the study of the ecological effects of a large reservoir on the local ecology. The reserve covers an area of 390,368 ha (1,507.22 sq mi). It is situated in the Shushensky District of Krasnoyarsk Krai.
The Northeast Siberian taiga ecoregion is an area of "sparse taiga forest" between the Lena River and the Kolyma River in northeastern Siberia, Russia. The ecoregion's internal borders form a patchwork of territory constituting the southern part of the East Siberian Lowland, as well as lowlands around the East Siberian Mountains, including the ridges and peaks of the Verkhoyansk Range and the Chersky Range. On the southern border of the ecoregion is the north coast of the Sea of Okhotsk, giving the region maritime boreal forests as well as the continental forests situated inland. The ecoregion is one of the largest tracts of virgin boreal forest in the world, due to the very sparse population and difficult access. It is mostly in the Sakha Republic.
The Da Hinggan-Dzhagdy Mountains conifer forests ecoregion covers the Greater Khingan Mountains of Northeast China, and across the border north into the Russian Far East where it follows the mountain ridge for another 500 km to the east. The mountain forests exhibit a floral community called "Daurian flora", a combination of the Siberian taiga to the north and the Manchurian floral types to the south. The eastern slopes are steep and drained by many rivers, the western slopes are gentler, and there are grasslands on some slopes. The ecoregion is in the Palearctic realm, with a subarctic climate. It covers 35,199,998 km2 (13,590,795 sq mi).
The Sayan montane conifer forests ecoregion 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. The ecoregion is in the Palearctic realm, with a cold semi-arid climate. It covers 35,741,835 km2 (13,800,000 sq mi).
The Selenge–Orkhon forest steppe ecoregion stretches across north central Mongolia, and follows the Selenga River northeast into Russia. The ecoregion is itself at high elevations, but surrounded by higher mountain ranges. As a transition zone between taiga and steppe, it features conifer forests on the north slopes of mountains, and pine/aspen stands on southern slopes. It has an area of 227,660 square kilometres (87,900 sq mi).
The Manchurian mixed forests ecoregion covers the forested hills surrounding the river plains of northern China, Russia, North Korea, and South Korea. The ecoregion supports a number of rare species due to the relative isolation, the diversity of habitat, with mixed forests of deciduous Mongolian oak and conifers of Korean pine. Because mountains rise above the region on three sides, with plains and wetlands below, the area supports high biodiversity as a transition zone.
Tarvagatai Nuruu National Park covers the southwestern sector of the Tarvagatai Range of the Khangai Mountains in central Mongolia. The park is remote, protecting a transition zone between semi-arid steppe to the south and coniferous forests on the northern slope of the range. A large fire burned a significant part of the park in 2002, including 800 square kilometres (310 sq mi) of forest, mostly larch and siberian pine. The park is located about 60 km northeast of Uliastai, in the eastern region of Zavkhan Province.
The Khangai Mountains alpine meadows ecoregion runs along the central ridge of the Khangai Mountains in central Mongolia. The slopes to the north are conifer forests, the lowlands to the south are semi-arid steppe. The Khangai are an "island" mountain range surrounded by lower forest steppe and semi-arid regions of central Mongolia. Most of the region is now protected by Tarvagatai Nuruu National Park and Khangai Nuruu National Park.
Khangai Nuruu National Park stretches in a west-to-east band across the middle of the Khangai Mountains, with the eastern half following the upper Orkhon River valley. There are a variety of habitat types in the park: steppe, riparian forests, larch taiga, and alpine meadows.
Khorgo-Terkhiin Tsagaan Nuur National Park covers the picturesque Terkhiin Tsagaan Lake and the nearby Khorgo Mountain in the north central Khangai Mountains of Mongolia. The marshes along the west end of the lake are an important breeding and staging area for birds. The park is located in Tariat District of Arkhangai Province.
Onon-Balj National Park covers two sectors of the Onon River valley as it flows north from Mongolia into Russia. The region is in the transition zone between the Siberian conifer forests of the north and the Daurian steppe and forest steppe of Mongolia. The area is one of relatively high biodiversity, and is also historically and culturally important for its association with Genghis Khan. The park is located in the far northeast of Khentii Province, 280 km northeast of Ulaanbaatar.
The Taiheiyo montane deciduous forests ecoregion stretches for about 700 km (430 mi) along the eastern slopes of the island of Honshu, with some small patches on the southern islands of Shikoku and Kyushu. Lower elevations to the east along the coast are in the Taiheiyo evergreen forests ecoregion; higher elevations to the west are in the Nihonkai montane deciduous forests ecoregion. Characteristic forests are of Japanese beech, stone pine, and spruce.
Salair National Park is located on the west slope of the Salair Ridge, which separates Altai Krai from Kemerovo Oblast. The low mountains are covered with coniferous forest, while the non-park surroundings to the west are steppe and forest steppe that has mostly been converted to agriculture. Because of its warm, humid summers, scientists have referred to Salair as the "rainforest of Siberia", with resulting high biodiversity and relict plants preserved from the pre-glacial period. The park was officially created in 2020; it is located in the districts of Zarinsk, Togulsky, Yeltsovsky and Soltonsky of Altai Krai.
