Russia extends from the Baltic Sea to the Pacific Ocean over much of northern Eurasia. It is the world’s largest country in total area. Russia displays both monotony and diversity.The changes in vegetation reflect the changes in climate: from north to south the East European Plain is clad sequentially in tundra, coniferous forest (taiga), mixed and broadleaf forests, grassland (steppe), and semi-desert (fringing the Caspian Sea). Siberia supports a similar sequence but is predominantly taiga.The country contains forty UNESCO biosphere reserves.
Russia is bounded by Norway, Finland, the Black Sea, Estonia, Latvia, Georgia, Azerbaijan, Belarus, Ukraine, Kazakhstan, Mongolia, China, the Pacific Ocean and the Arctic Ocean.
