The Tian Shan montane conifer forests ecoregion (WWF ID: PA0521) covers the "forest belt" of the Tian Shan mountains - generally the north-facing slopes that get enough moisture, and are warm enough, for trees to grow. This conifer belt is found mostly between 1,500 and 2,700 meters. [1] [2]

Location and description

The ecoregion stretches in patches on the main Tian Shan mountain ridge, across approximately 2,000 km from western Kyrgyzstan to eastern Xinjiang Province in China. The conifer forest belt is found on north-facing slopes, at altitudes from a minimum of 1,500 meters (below which it is too dry to support conifers) to a maximum of 2,700 meters (above which it is too cold). The disconnected components of the ecoregion tend to be elongated along ridges that average 4,000 meters in height, with one of the larger sections wrapping around Lake Issyk-Kul. [1] In general, the landscape below the forest belt is steppe, and above is alpine meadow with occasional dwarf junipers.

Climate

The climate of the ecoregion is cold semi-arid (Köppen climate classification (BSk)). This climate is generally characterized as having precipitation greater than a true desert, and also a colder temperature. [3] [4]

Flora and fauna

The dominant conifer in these forests is the Asian spruce ( Picea schrenkiana ), which usually grows in stands of the same species. Aspen is found mixed with the spruce at lower altitudes. Birch, willow, and mountain ash are found at higher altitudes. At lower altitudes within the forest belt, an understory of shrubs, grasses and forbes are found under the tree canopy. [1]

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.

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.

Zhongar-Alatau National Park, also Jungar Alatau, or Dzungurian Alatau, was created in 2010 to protect the unique ecology of the Dzungarian Alatau, an isolated, glaciated mountain range in Kazakhstan, on the southeastern border with China. One stated reason for creating the park is to protect forests of wild fruit trees, including apricots, barberry, cherries, and currants. Approximately 1% of the land area of the park is forested with Sievers Apple trees, which are the progenitors of all cultured apple varieties in the world. The park is 300 km long (west-to-east), and spreads across Aksu District, Sarkand District and Alakol District of Almaty Region, 300 km northeast of the regional city of Almaty.
