In mountainous areas, the decrease in temperature with increasing altitude leads to the
corresponding change in natural vegetation. As such, there is a succession of natural
vegetation belts in the same order as we see from the tropical to the tundra region. The wet
temperate types of forests are found between a height of 1000 and 2000 metres. Evergreen
broad-leaf trees, such as oaks and chestnuts predominate. Between 1500 and 3000 metres,
temperate forests containing coniferous trees, like pine, deodar, silver fir, spruce and cedar,
are found. These forests cover mostly the southern slopes of the Himalayas, places having
high altitude in southern and north-east India. At higher elevations, temperate grasslands
are common. At high altitudes, generally, more than 3,600 metres above the sea level,
temperate forests and grasslands give way to the Alpine vegetation. Silver fir, junipers,
pines and birches are the common trees of these forests. However, they get progressively
stunted as they approach the snow-line. Ultimately, through shrubs and scrubs, they merge
into the Alpine grasslands.
