Introduction to Forest : CBSE / NCERT Notes

Kerala, which is one of the India's southern states, is also known as "God's own country". It is rich in natural vegetation. The forests are spread over a large area, and consist of tropical wet evergreen, partly evergreen, deciduous and dry forests.

Some plants found in these forests are known for their medicinal value. These forests have given Kerala its healing touch in the form of Ayurvedic medicines for the treatment of various ailments.

Endemic species
When an animal or a plant is found in a specific area, it is known as an endemic species.

Wayanad Wildlife Forest

It's a large collection of flora and fauna.  Many endemic species of animals, such as pale-faced monkeys called bonnet macaques, striped-neck mongoose, small Indian civet, striped hyena, jackal, Indian fox, wild bear, giant squirrel, bison, chital and others, are found here. 

Kerala's forests have huge Neem trees that can grow up to a height of 50 to 65 feet. The Neem tree has high medicinal value and is said to treat around 40 diseases. The wood of the Neem tree is used to make a musical instrument, called the dhol.
Trees such as the bamboo, which can grow at the rate of 45 inches in a day, the fig tree, the amla tree or the Indian gooseberry, the Sal tree or the sandal wood tree, the teak tree and many more are all found in these forests. The crown, i.e. the branchy part of a tree above the stem, is not of the same type and size for all the trees. So they appear like different layers in the forest and are known as under storey. 

Apart from all these trees, the forest is covered with shrubs, herbs, tall grasses, creepers and climbers. The branches of the tall trees are just like a roof over the other plants, and are called the canopy. The soil of the forest is moist and warm because it is covered with leaves and fruits. The floor of the forest is a soft spongy carpet laid with dry leaves. Dead and decaying leaves, fruits and herbs produce a black substance called humus, which is good for the growth of the plants. Saprophytic organisms and micro-organisms convert the dead waste into humus. 

Plants are called producers because they prepare their own food. These producers are eaten by animals that are the primary consumers, which are, in turn, eaten by other animals that are the secondary consumers. Finally, the secondary consumers are eaten by the tertiary consumers.
Thus, forests play a very important role in the food chain. When forests are affected, they affect living beings such as animals and plants.
