Endangered animals
初一3 黄一轩
Hello, everyone! My topic today is the protection of endangered animals.
The Przewalski’s Horse
The Przewalski's Horse, also known
as the Mongolian wild horse, is named
after the Russian colonel Nikolai
Przhevalsky, the explorer and
naturalist who first described the horse in 1881. Many of these horses were captured around 1900 by a German and placed in zoos. About twelve to fifteen reproduced and formed today's population. By the end of the 1950s, only 12 individual Przewalski horses were left in the world. So it was classified "extinct in the wild". In 1992, sixteen horses were released into the wild in Mongolia, followed by additional animals later on. One of the areas to which they were reintroduced became a national park in 1998. The reintroduced horses successfully reproduced, and the status of the animal was changed from "extinct in the wild" to
"endangered" in 2005. The Przewalski's Horse is considered the only remaining truly wild "horse" in the world.
The Siberian tiger
The Siberian tiger , also
known as the Amur tiger, is a
tiger subspecies living mainly
the Sikhote Alin mountain
region with a small subpopulation in southwest Primorye province in the Russian Far East. In 2005, there were 331–393 adult-subadult Amur tigers in this region, with a breeding adult population of about 250 individuals. The population has been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population is declining. The Siberian tiger together with the Caspian and Bengal tiger subspecies represents the largest living felid and ranks among the biggest felids that ever existed. Phylogeographic analysis with extant tiger subspecies suggests that less than 10,000 years ago the ancestor of Amur and Caspian tigers colonized Central Asia via the Silk Road from eastern China then subsequently traversed Siberia eastward to establish the Amur tiger population in the Russian Far East.。
