July are and . The western areas also receive more rainfall than the eastern ones by per year. This is because the mountains trap clouds from the Atlantic Ocean. The highest precipitation, approximately , is in the Northern Urals with up to snow. The eastern areas receive from in the north to in the south. Maximum precipitation occurs in the summer: the winter is dry because of the Siberian High. Flora The landscapes of the Urals vary with both latitude and longitude and are dominated by forests and steppes. The southern area of the Mughalzhar Hills is a semidesert. Steppes lie mostly in the southern and especially south-eastern Urals. Meadow steppes have developed on the lower parts of mountain slopes and are covered with zigzag and mountain clovers, Serratula gmelinii, dropwort, meadow-grass and Bromus inermis, reaching the height of . Much of the land is cultivated. To the south, the meadow steppes become more sparse, dry and low. The steep gravelly slopes of the mountains and hills of the eastern slopes of the Southern Urals are mostly covered with rocky steppes. River valleys contain willow, poplar and caragana shrubs. Forest landscapes of the Urals are diverse, especially in the southern part. The western areas are dominated by dark coniferous taiga forests which change to mixed and deciduous forests in the south. The eastern mountain slopes have light coniferous taiga forests. The Northern Urals are dominated by conifers, namely Siberian fir, Siberian pine, Scots pine, Siberian spruce, Norway spruce and Siberian larch, as well as by silver and downy birches. The forests are much sparser in the Polar Urals. Whereas in other parts of the Ural Mountains they grow up to an altitude of , in the Polar Urals the tree line is at . The low polar forests are mixed with swamps, lichens, bogs and shrubs. Dwarf birch, mosses and berries (blueberry, cloudberry, black crowberry, etc.) are abundant. The forests of the Southern Urals are the most diverse in composition: here, together with coniferous forests are also abundant broadleaf tree species such as English oak, Norway maple and elm. The Virgin Komi Forests in the northern Urals are recognized as a World Heritage site. Fauna The forests of Urals are inhabited by animals typical of Eurosiberia, such as elk, brown bear, fox, wolf, wolverine, lynx, squirrel, Siberian chipmunk, flying squirrel, reindeer and sable (north only).
