Plants in mongolia

Plants in mongolia: Mongolian vegetation presents special features which have developed through time and because of local landscape forms, the environment and climate. Mongolia is a site of convergence with flora originating both in the Great Siberian Taiga and the central Asian steppe and desert.
Mongolia has acquired plant species from Manchuria in the east and from the Kazakhstan-Turan area in the west. The gradual transition from high mountain taiga, to mountain forest steppe and flat grassy plains, and on to semi-desert and true desert, offers features of the world's three basic vegetation regions. This is reflected in the change in precipitation and plant distribution, from foothills to the tops of mountain ranges in vertical belts. Mongolia has over 2,823 plant species, while central Siberia has 2,400 and Inner Mongolia has 2,176.
There are 845 species of medicinal plants; over 1,000 of fodder plants; 173 of food plants; 489 of ornamental plants; and 195 of other significant plants. Mongolia has 2,095 species of herbaceous plant and 348 species of woody and shrubby plants. These comprise 17 species of big trees; 40 species of low trees and gig shrub; 146 species of shrub; 48 species of sub-shrubs; 91 species of partial sub-shrubs; 6 species of fodder and herbaceous; 1,765 species of longevity plants; 330 species of one- and two-year vascular plants; 21 families of flat moss; 38 families of leafy moss; 53 families of lichen; 1,236 species and sub-species of algae; and 900 species of mushrooms. There are relic species from prehistoric desert, forests, tertiary lakes, savannahs and the Ice Age in particular, many native to Mongolia. There are about 150 endemic vascular and lower plants, such as stipa mongolorum; adonis mongolica; betula mongolica; atraphaxis bracteata; calligonum gobicum; nanophyton mongolicum; gymnocarpus przewalskii; silene mongolica; potaninia mongolica; chesneya mongolica; astragalus gobicus; oxytropis ulzii-chutagii; and armisia gobica.

The Khangai, Gobi-Altai and Mongolian Altai regions are the most abundant in species. Eighty-six plant species were registered as endangered or threatened in the first edition of the Mongolian Red Book. In the second edition (1997), this had increased dramatically, and included 75 medicinal species, 11 of food, 16 used in industry, 55 decorative species and 15 species used in soil fixing or controlling pests. The group includes nitraria sibirica; amygdalus mongolica; populus diversifolia; caragana bungei; artemisiacaespitosa; sophora alopecuroides; allium altaicum; adonis mongolica; saussurea involucrate; agriophyllum pungens; elaeagnes moorcroftii; aves sibirica; gemnocvarpus przewalskii; rodiola rosea; and allium oliquum. A law was passed in 2003 on international trade in animals, plants and related items, resulting from Mongolian membership of the 1975 CITES (Convention on International Trade in Endangered Species of Wild Flora and Fauna. Failure to meet convention standards results in an embargo on exports and imports, and stopping of financial assistance and support from other signatories.
Mongolia joined CITES in 1996 but still earns Tg1.5 billion from the international trade in endangered native flora and fauna. Mongolia has 14 mammal species, 71 birds, eight plants and two fish on the CITES protected list. These include the takhi, mazaalai (Gobi bear), snow leopard, wild ass, Siberian crane, white-naped crane, Dalmatian pelican, Macqueen's (Houbara) bustard, relict gull, Japanese crane and the oriental white Mongolian stork. However the grey wolf, lynx, musk deer, argali, saker falcon, apollo butterfly, European wild cat, Eurasian otter, elk, moose, tatar sand boa, Siberian and Amur sturgeon can still be traded with CITES permission. The Environment Ministry has a council to license such trade.
