Ural Economic Region () is one of twelve economic regions of Russia. This prominent industrial region consists of the following subdivisions (with their administrative centers): Bashkortostan (Ufa), Chelyabinsk Oblast (Chelyabinsk), Kurgan Oblast (Kurgan), Orenburg Oblast (Orenburg), Perm Krai (Perm), Sverdlovsk Oblast (Yekaterinburg) and Udmurt Republic (Izhevsk). It is mostly located in the Central, and partly in the Southern and Northern parts of the Urals, but also includes parts of the East European and West Siberian Plains. Its extent is different from that of the Ural Federal District; Bashkortostan, Orenburg Oblast, Perm Krai and Udmurtia are in the Volga Federal District while the other three are in the Ural Federal District. Geography and natural resources The region is crossed by rivers belonging to the Volga basin (Kama, Vishera, Chusovaya and Samara), Ob basin (Tobol, Iset, Tura and Tavda) and the Ural River basin. Their potential hydropower resources are estimated at 3.3 million kilowatts. By 2010, there are only two dams and associated reservoirs, both on the Kama River: Votkinsk Reservoir and Kama Reservoir. The climate is temperate continental in the western and continental in the eastern part of the region. More than 40% of the area is covered by taiga forests having the timber reserves of 3.5 billion cubic meters. The southern part is dominated by the steppe, which is largely cultivated. The area is exceptionally rich in various ores and minerals, such as valuable chalcopyrite, nickel oxide, chromite, magnetite, bauxite, potassium salts, manganese, aluminium, gold, platinum, as well as coal, oil and natural gas. The area is famous for semi-precious stones, such as emerald, amethyst, aquamarine, jasper, rhodonite, malachite and diamond. Industry Ural economic region accounted for 10 per cent of the national GRP in 2008. It has a diverse and complex structure of machinery and metal industries. Nationwide importance have ferrous and nonferrous metallurgy, mechanical engineering, chemistry, mining of minerals and natural gas, logging and wood processing. The Ural industry is characterized by the high concentration of production around certain areas, such as transport hubs, close cooperation between different branches and recycling of industrial waste. The timber production is concentrated in the north and agriculture mostly in the south. The areas of the Central Ural regions on the both sides of the Ural Mountains (Sverdlovsk, Nizhny Tagil, Chelyabinsk, Magnitogorsk, Orsk) are dominated by mining and processing of metals and suburban agriculture. The basin of Kama River (Berezniki, Solikamsk, Perm,
