), depriving them of their habitat and traditional ways of life. LOGATA, Moscow. ReferencesAbaimov, A. P., J. Redkie I nuzhdajushiesja v ohrane rastitel’nye soobshestvsa. [8] In the southwest of the region is the Vasyugan Swamp, one of the largest swamps in the world, with peat extending to an average depth of 2.3 meters. It is a vast, flat lowland region of boreal forests (taiga), and wetlands (40% of the region is swamps and bogs), covering an area about 1,800 km west–east, by 1,000 km north–south. The main threats to this ecoregion's integrity are poaching and clear-cut logging in the southern and central portions of the region. There are 80 species of mammals in the ecoregion, but none of them are endemic (found only in Western Siberia). The waterlogged nature of the terrain is due to the flat terrain, the heavy river flows from the south, and the fact that precipitation exceeds evaporation in the region. Rare and endangered plant communities]. [Green book of Siberia. The climate is strongly continental, reaching its extremes in the region’s northeast. 1998; Zelenaya Kniga… 1996). This region contains the highest number of brown bears (Ursus arctos collaris), Eurasian wolf (Canis lupus), moose (Alces alces) and wild reindeer (Rangifer tarandus) in Russia. Nauka, Moscow. editors. Flora and fauna of zapovednikov. To the north is the tundra, with a tree line transition zone that is about 100 km of gradually thinning tree cover. Vodop’yanova, N. S. 1984. There are 11 nationally threatened vertebrate species, including Aquila chrysaetos, Pandion haliaetus, Falco peregrinus, Ciconia nigra and Grus monacha. Zapovedniki Sibiri. A. Lesinski, O. Martinsson, and L. I. Milyutin. Husum. [5] Large numbers of birds migrate to the area each year, but relatively few species stay year-round. Nevertheless, the existing network of protected areas is not sufficient for such an extensive region. To the north is the tundra of the Yamal-Gydan tundra ecoregion (covering the Ob River estuary and related peninsulas).[1][4]. Swedish University of Agricultural Sciences. The diversity of this taiga is not fully represented in the protected area network. Although little of this ecoregion is protected, its conservation status is listed as "Relatively Stable/Intact". The anticyclone weather dominates most of the year. Located away from the Atlantic Ocean, and the center of Eurasian landmass, the climate of the Western Siberian Plain is mildly continental. Zapovedniki I natsional’nye parki Rossii. There have been numerous attempts of deforestation in the protected floodplain of the rivers. After the collapse of the Soviet Union, came a new threat. The southern edge of the region lies north of the belt of temperate forests and forest-steppe that runs along the Trans-Siberian railway. The ecoregion is very rich in mineral resources. The dominant vegetation formation is light coniferous taiga with Larix gmelini forming the canopy in areas with low snow cover. Novosibirsk, "Nauka". The maximum width from north-to-south is 1,600 km. The ecoregion boundary corresponds to the central and sparse forest taiga in the Central Siberian forest province and the East Siberian forest province west of the Dzhugzhur Mountains in Kurnaev’s (1990) forest map of the USSR. Justification of Ecoregion DelineationThis ecoregion lies in between the Yenisei River and the Verkhoyansk Mountains in Russia. Nationally endangered plant species (15 species in total) include: Cypripedium macranthon, Calypso bulbosa, Orchis militaris and Cotoneaster lucidus. [Zapovedniks of Siberia]. View our inclusive approach to conservation. Taiga SSSR. The Enisey River and its tributaries contain 42 species of fish. 54. It is a vast, flat lowland region of boreal forests (taiga), and wetlands (40% of the region is swamps and bogs), covering an area about 1,800 km west–east, by 1,000 km north–south. Prepared by: Sergei PonomarenkoReviewed by: Olga Alexandrovna Zyryanova, 1250 24th Street, N.W. Husum Druck-Verlag. [1], Also known as the Siberian Lowlands, the region is a large sink for atmospheric carbon dioxide, both in the forests and boggy peatlands. Because of the large environmental damage, their activities caused protests by local residents and the World Wide Fund for Nature[2][3]. This ecoregion is vast, spanning over 20 degrees of latitude and 50 degrees of longitude. The fauna is believed to have developed earlier here than in Western Siberia. Protected areas in this ecoregion include: All are "Zapovedniks", (that is, strict ecological reserves). Larch forests dominate the region as they are able to withstand the extreme continental climate and dry winters. The western edge of the region is the Urals mountains, and the western half of the region is dominated by the Ob River and its main tributary the Irtysh River. The eastern Siberian taiga is considered the heart of Siberia because most of the typical Siberian species are best represented there. The region is in the Palearctic realm (Euro-Siberian region), with a (Dfb) climate. The actions of the Chinese companies pose a threat to the native population of Siberia and the Far East (Evenks, Udege et al. Winters are long and very cold, but dry, with little snowfall due to the effects of the Siberian anticyclone. Larch forests dominate the region as they are able to withstand the extreme climate conditions. To the south of the ecoregion in forest-steppe transition, the climate grades to Humid continental climate (Koppen Dfa), where the temperature variations, seasonally and diurnally, are wider and the precipitation throughout the year is more evenly distributed. 1998. The following plant associations need priority protection: Pinus sylvestris-Duschekia fruticosa-Vaccinium vitis-idaea+Scorzonera radiata+Limnas stelleri, Pinus sylvestris-Sobcotoneaster pozdnjakovii-Dryas viscosa+Carex pediformis, Picea ajanensis-Pinus pumila-Diplazium sibiricum+Pyrola incarnata+Vaccinium vitis-idaea-Hylocomium splendens, Pinus sylvestris-Pinus pumila-Cladina stellaris+Cl.rangiferina, Pinus sylvestris-Arctostaphyllos uva-ursi+Pulsatilla flavescens (Zelenaya kniga.., 1996). Forest regionalization of the USSR (1:16,000,000). Washington, DC 20037. Precipitation is low, ranging from 200 to 600 millimetres (8 to 24 in), decreasing from east to west. Types and Severity of ThreatsThe main threats are widespread forest fires, intensive clear-cuts in the central and southern taiga subzones and poaching. Further south mammals in the East Siberian taiga include Siberian musk deer (Moschus moschiferus), Altai wapiti also known as Asian elk (Cervus canadensis sibiricus) and wild boar (Sus scrofa). Variability and ecology of Siberian larch species. LOGATA, Moscow. [2] The peatlands of Western Siberia are the most extensive in the world, covering an area the size of Texas.

Department of Silviculture. Goljakov, P. V. 1994. Annotirovannyj spisok vidov. The taiga or boreal forest has been called the world's largest land biome. In Krasnoyarsky Krai, which constitutes only part of the ecoregion, there are 4 species of amphibians, 2 species of reptiles, 203 species of birds and about 80 mammals (Syroechkovskij, Rogacheva 1980). Department of Geodesy and Cartography, Moscow. Some trees also shed their leaves annually, a characteristic of deciduous forests. Pine forests and deciduous forests composed of birch and poplar species become more common as one moves south, and at the headwaters of the Lena River and the Nizhnyaya Tunguska River, as well as in the Angara River basin, steppe and shrub-steppe communities can be found along with areas of forest-steppe. This vast ecoregion is located in the heart of Siberia, stretching over 20° of latitude and 50° of longitude[1] (52° to 72° N, and 80° to 130° E).
