also includes species like Arctic Fox and lemmings. Because of the easy accessibility of the mountains there are no specifically mountainous species. In the Middle Urals, one can see a rare mixture of sable and pine marten named kidus. In the Southern Urals, badger and black polecat are common. Reptiles and amphibians live mostly in the Southern and Central Ural and are represented by the common viper, lizards and grass snakes. Bird species of Northern, Middle and South Urals are represented by Western Capercaillie, black grouse, hazel grouse, spotted nutcracker, Siberian Jay, Common and Oriental cuckoos. Unlike mammals, the highest peaks and platoes of Northern and Southern Urals are inhabited by some mountaneous or tundra avian species, like Golden Plover, Dotterel, Ptarmigan and Willow Grouse, in Polar Urals also by Rough-legged Buzzard and Snowy Owl. The steppes of the Southern Urals are dominated by hares and rodents such as hamsters, susliks, and jerboa. There are many birds of prey such as lesser kestrel and buzzards. Ecology The continuous and intensive economic development of the last centuries has affected the fauna, and wildlife is much diminished around all industrial centers. During World War II, hundreds of factories were evacuated from Western Russia before the German occupation, flooding the Urals with industry. The conservation measures include establishing national wildlife parks. There are nine strict nature reserves in the Urals: the Ilmen, the oldest one, mineralogical reserve founded in 1920 in Chelyabinsk Oblast, Pechora-Ilych in the Komi Republic, Bashkir and its former branch Shulgan-Tash in Bashkortostan, Visim in Sverdlovsk Oblast, Southern Ural in Bashkortostan, Basegi in Perm Krai, Vishera in Perm Krai and Denezhkin Kamen in Sverdlovsk Oblast. The area has also been severely damaged by the plutonium-producing facility Mayak, opened in Chelyabinsk-40 (later called Chelyabinsk-65, Ozyorsk), in the Southern Ural, after World War II. Its plants went into operation in 1948 and, for the first ten years, dumped unfiltered radioactive waste into the river Techa and Lake Karachay. In 1990, efforts were underway to contain the radiation in one of the lakes, which was estimated at the time to expose visitors to 500 millirem per day. As of 2006, 500 mrem in the natural environment was the upper limit of exposure considered safe for a member of the general public in an entire year (though workplace exposure over a year could exceed that by a factor of 10). Over of land were
