Conservation of Wildlife Resources

The term wild life generally refers to those organisms that live in their natural habitat. And the term conservation means the protection of nature and natural resources for future generation by using it sustainably.

Importance of wildlife conservation:

Economic value: Wildlife resources are the main resource on which human beings depend. It provides various raw materials for textile, leather,tannis, dyes, timber, and furniture for the industries and people can earn money by selling them. From animals fur, wool, horn, bone, silk, meat, leather etc can be produced and by selling them money can be earned.

Food Value: It provides the vast majority of foodstuffs. Many kinds of animals and plants are lived and grow in different climate and geographical conditions. These plants and animals supply lots of food products such as fruits, cereals, nuts, mushroom, honey, meat, mike etc.

Medicinal value: It is estimated that 80% of people in the developing world depend directly on traditional medicines derived from plants and animals. More than 1500 plants of Nepal have medicinal value.

Other value: Biological diversity exerts direct influences on regional and local weather patterns. Plant purifies the air and regulates the composition of the atmosphere, recycling oxygen and filtering harmful particles release due to industrial activities.

Categories of wildlife status:

Following species are placed in a threat species by IUCN (International union of conservation of nature and natural resources).

Extinct (Ex): species not definitely located in wild during the past 50 years. On a few occasions, the category Ex? Is used; this donates that it is virtually certain that the taxon has recently become extinct.

Endangered (E): Taxa in danger of extinction and whose survival is unlikely if the casual factors continue to operate. Also included are taxa that may now be extinct although they have been seen in the wild in the past 50 years, e.g. Talauma hodgsonii.

Vulnerable (V): Taxa believed likely to move into the endangered category in the near future if the casual factors continue operating. Included are taxa of which most or all the populations are decreasing because of over-exploitation, e.g. Nardostachys grandiflora, Paris ployphylla etc.

Rare (R): Taxa with small world populations that are not present endangered or vulnerable but are at risk. These species are usually localized within restricted geographical regions or habitats.

Indeterminate (I): Taxa known to be endangered, vulnerable or rare but where there is not enough information to say which of the three categories is appropriate.

Insufficiently known (K): Taxa that are suspected but not definitely known to belong to any of the above categories, because of lack of information.

Threatened (T): The general term threatened is used to refer to a species considered to belong to any one of the above categories.

Commercially threatened (CT):Taxa not currently threatened with extinction, but most or all of whose population are threatened as a sustainable commercial resource or will become so.

Causes of extinction of wildlife: Like most developing country, threat to biodiversity in Nepal is initiated by the activities of the human beings. Habitat destruction and over-exploitation are the main cause of extinction of wild life.

a. Habitat loss, forest destruction and degradation: In Nepal the greatest threat to the conservation of wildlife comes from the activities of man which include habitat loss and forest destruction. The destroying habitat of wild life by overpopulation for commercial timbering, cropland, industries, road ways, canal developmental activities, for fuel wood, power plants cause wildlife extinction.

b. Over-exploitation of forest resources: People to large extent depend on forest resources for their sustenance. People use forest products for fulewood, fodder, timber, shelter, medicine and food plants which increase the extinction of wild life.

c. Illegal hunting and poaching: Illegal hunting is common practice throughout Nepal. Mammals and birds are killed, river fish stocks are overexploited, dolphins are trapped for meat, pheasants are hunted for their meat and carnivores are hunted for their pelts and bones.

d. Trade: There has been commercial trade of wild flora and fauna both legally and illegally. One of example is one-horned rhinoceros which is in decreasing amount due to trading.

e. The population growth and poverty is also the main cause of wild life extinction.

Conservation and management of wildlife


Conservation strategy

- The habitat study, protection, improvement and habitat management should be done.

- The habitat of wildlife should be increased.

- Population growth rate should be decreased.

- The data about the wildlife should be refreshed and should collect in regular interval.

- The laws in the field of trade and hunting of wild life should make tight and fine amount should be high.

- Education, and public awareness should be done.

- Establishment of national parks and wild life reserves.

- Scientific researches should be done and the threatened species should get priority in order to conserve them.
