Some of the more interesting mammals of the desert include the Bactrian camel (Camelus krus), the Gobi bear (Ursus arctos), the Asiatic wild ass (Equus hemionus), various species of jerboa, and the northern mole vole (Ellobius talpinus). Some of these, such as the Gobi bear, are now very rare. Birds such as Pallas’s sandgrouse (Syrrhaptes paradoxus) and the saxaul sparrow (Passer ammodendri)also make their home in the desert. Also reptile of agamid lizards are common in the desert zone. Desert SteppeStretching from Depression of Great Lakes, the Valley of Lakes and the Middle and Eastern Gobi Low Lands, the climate of this zone is dry with annual precipitation of 100-200 milliliters. Loose soil and high wind hinders the growth of plants and adapt them to be low grasses and shrubs. Numerous endemic plants of Central Asia, can be seen in this zone such as Cleistogenes songorica, Artemisa frigida, Caragana and the Taana onion (Allium polyrrhizum). Characteristic mammals include the wild ass, the goitered gazelle (Gazella subgutturosa) and the long-eared hedgehog (Erinaceus dauuricus). Birds such as the Mongolian trumpeter finch (Rhodopechys mongolicus), the chukar (Alectoris chukar) and the houbara bustard (Chlamydotis undulata) occur in this desert steppe zone. SteppeStretching from Khangai mountain range, this zone covers vast flat plain and rolling hills from westwards to northwest area. The vegetation is mostly abundant of feather grass and shrubs including Stipa krylovii , Agropyron cristatum, Caragana species and Artemisia species . Large mammals of the steppe include saiga (Saiga tatarica), Mongolian gazelle (Procapra gutturosa) and corsac fox (Vulpes corsac); birds include the steppe eagle (Aquila nipalensis), the rough-legged buzzard (Buteo lagopus) and the pied wheatear (Oenanthe pleschanka). Smaller mammals such as the Daurian pika (Ochotona dauurica), the Siberian marmot (Marmota sibirica) and Brandt’s vole (Lasiopodomys brandtii) are common in places. Migration of the Mongolian gazelle was one of the last spectacles of mass migration, something that can been only in a small case on the Serengeti plains of Tanzania.Forest steppeBetween steppe and taiga or Khangai and Altai range, one specific feature of forest mountain steppe is that the back sides of the mountains are always covered with different species of forest and woody plants whereas south area facing sides are densely covered by the steppe plants, giving an impression of sharp boundaries of habitats of the mountain forest and steppe species. The rare vegetation of forest steppe includes Poa, Koeleria and their “cushion” communities,Adonis mongolica and Saussurea involucrata plant species. It also is encompassed with endangered animals including Manul, elk (Cervus elaphus), wolf (Canis lupus), marmots (Marmota spp), sousliks (Spermophilus spp), black kite (Milvus migrans), buzzards(Buteo spp) and black grouse (Lyrurus tetrix). The Siberian wood frog (Rana amurensis) and the sand lizard (Lacerta agilis) also inhabit here ,too. TaigaTaiga zone in the northern part of the country around Khankhokhii, Khuvsgul and Khentii mountain ranges , with 300-400 milliliters of precipitation , is a relatively cold and humid area. The warm deficiency causes short season for many bunch grasses, dwarf shrubs and steppe grasses species including Siberian Pine sibirica,Larix sibirica and the Siberian Larch sibirica. And this zone is inhabited by such animal species registered in the Mongolian Red Book as theMusk deer (Moschus moschiferus),’ reindeer (Rangifer tarandus), sable (Martes zibellina), snow leopard (Uncia uncia), moose (Alces alces) and brown bear (Ursus arctos) and a total of 62 species of mammals and 277 species of birds have been recorded. The taiga zone balances the overall ecological balance by checking in soil erosion and water regimes.AlphineThe Alpine belt of the Mongolian Altai,Khovsgol, Khangai and Khentii mountainous regions which mountains are with perpetual snow-capped peaks,are the main contractors of this zones characteristics. The extreme cold climate, snow and glacier covers are constantly preserved regardless of summer seasons. Due to extreme climate, the vegetation is low including low shrubs and herbs, sedges, grasses, mosses, algae and lichens and is inhabited by few endangered animals including the Wild Mountain Sheep, Siberian Ibex, Snow Leopard, dotterel , Himalayan accentor, Rock Ptarmigan ,and Altai Snowcock and plants including SPECIES DIVERSITY Though relative to subtropical and tropical countries, Mongolia’s number of species are low , the collection of species and their quirky correlation with their ecosystem is almost one and only in Mongolia. According to the statistic house commision in Mongolia, it shows that 292 species of flora belonging to 20 genera, under 1 family of vascular higher plants were recorded in Mongolia. As of today, as in increased number, there are 3,014 species belonging to 676 genera, 112 families, 39 orders, 14 classes of 5 phyla (Urgamal et al., 2013). For Fauna, Of the 128 species of mammals in Mongolia, 16% are regionally threatened, of which 2% are Critically Endangered. And there are 476 species of birds and 22 species of 1 genus, 6 families of 2 sub-order reptiles and 6 species of 4 families of 2 orders of amphibians and 362 species of insects and unnotified species of fish habitating in Mongolia. Most decreasing in number as 90 percent of pasture land in Mongolia lies within a vulnerable region that is susceptible to desertification and land degradation and as projects against climate change are not highly supported. The low GDP of the country, leaves low budget for Conservation of Biodiversity, however external institutes including IUCT and UN have been encouraging and helping the project financially. GENETIC DIVERSITY Genes can be considered as the blueprint of the animals and living organisms coded in their DNA. It plays important role in the survival and adaptability of a species and it is essential that human race, the main directing power of today’s world to know the change in it. Most change in genetic, are caused by the environmental pollutions, or the human activities. So therefore, to save the genetic diversity depletion the country must act forwards the negative effects of urbanization and industrialization.CONCLUSION Though it is Mongolia’s pride to say that they have humongous storage for Biological Diversity, the reality of weak economical and ecological stability of the country, is crashing down the proud statistics. Having millions hectares of land being eroded and decreasing soil fertility by 20 percent , and losing more than 300 lakes, rivers, streams and water sources, the future for inhabitants will irreversibly heartbreaking. The number that of 100 animals and species becoming threatened by extinction in only 40 years, is warning that the danger has come and that it has started. Without knowing, rapid air, water, soil pollutions are taking place everywhere. Mongolia, a country which is economically suffering , is weak in regards of conserving the biodiversity and encouraging them financially and in policy aspects. Nomads who are in close relation with nature, are suffering because of the climate and industrial changes , and now, have no space to turn. Then separated traditional system of conservation, leaves organisms without care and with more suffering from pollutions and climate changes.So unless the nation take serious stronghold decisions on Conservation of Diversity matter, vulnerable Mongolia will be easy to crumble down. And the society dependent on the nature , moreover, the habitats famous for being only in Mongolia , will suffer irreparably.
