Expert Answer:

India is known for its rich biodiversity. The term ‘biodiversity’ is used to describe various life forms which are found on the Earth. This includes flora, fauna and various ecosystems in which species live or depend on one another.

Because of deforestation, the demand for hides and horns of animals and for medicinal plants, commercialisation etc., many species of plants and animals are on the verge of extinction at present.

Various survey reports suggest that about 10% of India’s flora (plant life) and 20 % of Indian mammals are facing threats of extinction. There is also the possibility that many more species of plants and animals may have become extinct in past. Indian forests are also fast vanishing. Though, according to the State of Forest Report, the forest cover in India has increases, it is to be noticed that this increase is due to the plantation programme carried out by different environment agencies. What the State of Forest Report failed to bring out is that natural vegetation and plantation are different from each other.

 

According to their present numbers, various species of plants and animals can be categorised into the following divisions:

Normal Species: Those species whose numbers are considered normal for their survival are known as normal species. Some examples are sal, pine, rodents and cattle.

Extinct Species: Extinct species are those species of plants and animals which cannot be found in the wild or in captivity in areas where they may occur. For example, the cheetah in India and the dodo bird in the world have become extinct.

Endangered Species: Species which are facing a grave threat to their lives and are in danger of becoming extinct are known as endangered species. Black buck and Indian rhino are examples of such species.

Vulnerable Species: These species can become endangered if positive steps are not taken to improve their numbers. Desert fox and Asiatic elephants are examples of such species.

Rare Species: Species which are very uncommon or scarce in numbers are called rare species. They can become vulnerable or endangered if their numbers continue to decline. Some examples of this species are wild Asiatic buffalo, hornbill and desert fox.

Endemic Species: These kinds of species are only found at a particular region, range or location in the world. Andaman wild pig and Nicobar pigeon are examples of such species.
