The World Wildlife Foundation and Saiga Antelope

They were almost swept away in the 1920s and nearly 2 million were found in the USRR prairie by the 1950s. Because they want a medical corner in China their population is decreasing due to USRR. Once the World Wildlife Fund wanted to kill these animals because that horn was substituted for the horn of Sai. Today, their population has dramatically decreased to 95% in 1995 (wow!). So far, 50,000 people live in Kalmaik of Kazakhstan and Mongolia. At the beginning of 2000, the number of Saiga increased to 21,000, reaching 81,000 by 2010.

In the vast grasslands of North America and Eurasia, massive migration of large vertebrate animals such as buffalo (Bubalus bubalis), Sagatata Turkica, Tibetan Antelope (Pantholops hodgsoni), and Can (Equus hemionus) are experienced. This special phenomenon currently occurs only in isolated pockets of Daur's meadow and Qinghai-Tibet Plateau (see Montane Grasslands). Extraordinary flower communities of the Eurasian prairie and Great Plains in North America almost disappeared due to the shift to agriculture. Nonetheless, in North America you can cultivate up to 300 different plant species in high grasslands of less than 3 acres, supporting more than 3 million insects per acre. Patagonia's meadows and meadows are known for their uniqueness at the general level and family level of the various groups.

Approximately 900 Saiga tatarica mongolica (nearly 10% of the sub-population) died in Hobud province in western Mongolia. Samples taken from corpses are positive for Peste des Petits ruminant (PPR), a highly fatal viral disease that these animals have a pest-like effect on livestock sheep and goats and can lead to death It is shown that it is. 90% of infected animals. People who died strongly suggest that livestock are causing overflow events in their common pasture land. Especially efforts are being made to investigate local conditions on other causes such as bacterial infection (P. pastoris) suspected to cause hundreds of thousands of Saiga people in Kazakhstan in 2015 .
