that retain green foliage all year round. Such forests may be broadleaved evergreen
forests, such as Moist forest that occur in tropical climates or coniferous evergreen
forests such as those found in temperate and boreal climates. Some subtropical or
warm temperate areas may contain laurel forest, which are broadleaved evergreen,
while isolated areas of evergreen forests may occur in montane forests, and cloud
forests. Tropical evergreen forests or (tropical rain forests) are usually found in
areas receiving more than 200 mm of rainfall and having a monthly mean
temperature of 18 C or higher in the coldest months. They occupy about seven per
cent the Earth's land surface and harbour more than half of the planet's terrestrial
plants and animals. Tropical evergreen forests are dense, multi-layered, and
harbour many types of plants and animals. The trees are evergreen as there is no
period of drought or frost. The canopy tree species are mostly tall hardwoods with
broad leaves that release large quantities of water through transpiration, in a cycle
that is important in raising as much mineral nutrient material as possible from the
soil.
Example:
In India, evergreen forests are found on the eastern and western slopes of
the Western Ghats in such states as Tamil
Nadu, Karnataka, Kerala and Maharashtra. And also found in Assam, Arunachal
Pradesh, Meghalaya, Nagaland, Tripura, West Bengal and Andaman and Nicobar
Islands. They are also found in the hills of Jaintia and Khasi. Some of the trees found
in Indian tropical forests
are rosewood, mahogany and ebony. Bamboo and reeds are also common. Because
of dense foliage competing for light, little direct sunlight reaches the under story.
The tropical evergreen forests usually occur in areas receiving more than 200 cm of
rainfall and having a temperature of 15 to 30 degrees Celsius. They occupy about
seven per cent of the earth's land surface and habours more than half of the worlds
plants and animals. They are found mostly near the equator.
These forests are dense and multi-layered. They harbour many types of plants and
animals. The trees are evergreen as there is no period of drought. They are mostly
tall and hardwood type. Leaves are broad and give out excess water through evapotranspiration.
In India, evergreen forests are found in the western slopes of the Western Ghats in
States such as Kerala and Karnataka. They are also found in hills of Jaintia and
Khasi. Some of the trees found in Indian Tropical Forests are rosewood, mahagony
and ebony. Bamboos and
reeds are also common.
