Conservation of Plants and Animals:

Conservation of Plants and Animals


Biodiversity The term biodiversity is derived from Greek word bios = life and diversity =variety. It may be defined as the variety of life forms found on our planet in a particular area.

What are megabiodiversity nations?:

What are megabiodiversity nations? They are the nations which are very rich in plants and animals.

Biodiversity in India:

Biodiversity in India India has a rich and varied biodiversity because of a variety of habitats such as deserts, grasslands tropical and temperate forests, costal wetlands and alpine vegetation. More than 50%of total species of plants and animals are found in India.

Threat to biodiversity:

Threat to biodiversity The various factors leading to extinction of wild species and depletion of biodiversity are:- Habitat loss due to increase in human population Deforestation and overgrazing Human greed Climatic changes Pollution

Need for conservation of biodiversity:

Need for conservation of biodiversity Biodiversity maintains balance in nature or balance in the ecosystem. Wild animals and plants provide a variety of commodities. Wildlife is needed for breeding programs in agriculture, horticulture, sericulture, apiculture, etc.

Flora and Fauna:

Flora and Fauna The plants found typically in particular area from the flora of that area. The term fauna represents the wild animals found in a particular region. For example the trees of jamun from flora of Himachal Pradesh and ber from flora of Rajasthan. Tiger represents fauna of Rajasthan.

Endemic species:

Endemic species Some species of plants and animals are found exclusively in a particular area and do not occur naturally anywhere else. Eg. Lion(Babbar sher) is endemic to Gir forests in Gujarat Himalayan weasel is endemic to Himalayan region Snow leopard is endemic to Himalayan range Wild mango and sal trees from endemic flora of Pachmarhi Biosphere Reserve Babbar Sher

Conservation of Biodiversity:

Conservation of Biodiversity Conversation of biodiversity essentially implies :- Conservation of forests Conservation of wild life

Conservation of forests:

Conservation of forests Forests are described as natural treasures and nature’s lungs. We can describe forests as well organized communities of flora and fauna on the earth. Main causes of forest depletion is deforestation

Process of clearing forests!:

Process of clearing forests! Rates of deforestation are particularly high in the tropics, where the poor quality of the soil has led to the practice of routine clear-cutting to make new soil available for agricultural use. Deforestation can lead to erosion , drought, loss of biodiversity through extinction of plant and animal species, and increased atmospheric carbon dioxide. Many nations have undertaken afforestation or reforestation projects to reverse the effects of deforestation, or to increase available timber.

Causes of Deforestation:

Causes of Deforestation Deforestation is clearing of forests for using the land for other purposes. This poses a serious threat to our resources, economy, quality of life and our environment. The causes of deforestation are:- Manmade causes of deforestation Natural causes of deforestation DEFORESTATION

Manmade Causes:

Manmade Causes Men are felling trees for:- Land for crops, vegetable etc. Clearing land for mining Cutting trees for making furniture

Natural Causes:

Natural Causes Forest Fire Severe Droughts Floods, earthquakes and landslides

Consequences of Deforestation :

Consequences of Deforestation Global warming Change in climate Desertification Drought Soil erosion and floods Loss of wildlife Depletion of resources

Forests conservation and management:

Forests conservation and management Preventing overgrazing Protection from fire, pests, and diseases Afforestation General awareness

Wildlife Conservation:

Wildlife Conservation Wildlife basically refers to organisms living in there natural habitats, like tigers in Dense forests.

Causes of Wildlife Depletion:

Causes of Wildlife Depletion Habitat Loss Indiscriminate Hunting Pollution Pollution

Threatened Species:

Threatened Species The species of plants and animals whose members are greatly reduced in a number or are near extinction are called threatened species. The IUCN has classified threatened species into the following categories:- Endangered species Vulnerable species Rare species ENDANGERED SPECIES

Red Data Book:

Red Data Book Red Data Book contains a record of all those species of plants and animals which are under threat of extinction or are rare and vulnerable for extinction. The Red Data Book is being maintained by the IUCN, Switzerland . Now this is known as World Conservation Union. This book provides information about the distribution and status of threatened species, and guides their conservation programmes.

Strategies for wildlife conservation:

Strategies for wildlife conservation Strategies for wildlife conservation include:- Creation of protected areas Strict laws to regulate hunting Captive breeding programmes

Protected areas:

Protected areas Protected areas are undisturbed habitats for wildlife. These include :- National parks Wildlife sanctuaries Biosphere reserves

Hunting regulation:

Hunting regulation Strict laws are needed to regulate hunting or poaching of animals. Hunting of endangered species should be banned. Destruction of natural habitats of wild animals should be prevented.


Migration The seasonal movement of animal in one group from e habitat to another is called migration. The animals that migrate are called migratory animals. The common are:- Birds Fishes Turtles Whales Butterflies

Need for Migration:

Need for Migration Animals migrate to:- Escape the inhospitable winter condition Find plenty of food lay eggs at warm place where they can incubate early
