Biodiversity: Types, Importance and Conservation Methods (with diagram)

Conserving biodiversity outside the areas where they naturally occur is known as ex situ conservation. Here, animals and plants are reared or cultivated in areas like zoological or botanical parks. Reintroduction of an animal or plant into the habitat from where it has become extinct is another form of ex situ conservation.

For example, the Gangetic gharial has been reintroduced in the rivers of Uttar Pradesh , Madhya Pradesh and Rajasthan where it had become extinct. Seedbanks, botanical, horticultural and recreational gardens are important centres for ex situ conservation. Conserving the animals and plants in their natural habitats is known as in situ conservation. This includes the establishment of. After the introduction of cotton, tobacco, sugarcane, sunflower, soyabean and so on, farmers became victims of monocultures in their greed for money.

Therefore many of the indigenous varieties of crops were lost. Moreover, the hybrid varieties of fruits and vegetables e. Though hybrid varieties are preferred, traditional wild varieties of the seeds should be conserved for future use in the event of an epidemic which would completely wipe out the hybrids. Botanical gardens, agricultural departments, seed banks etc.

Every farmer, gardener an cultivator should be aware of his role in preserving and conserving agrobiodiversity. The aim of the convention is to save species and plants from extinction and their habitats from destruction. The developed countries are looking for a sustainable supply of biological resources from the developing countries and easy access to them as well. The developing countries lacking the technology to exploit their resources are inviting the developed countries to do so.

This has resulted in the developed nations channeling out the benefits of these natural resources. The developing countries are now demanding a higher share of the accrued economic benefits.

The developed nations are also concerned by the unsustainable exploitation of natural wealth, particularly rainforests. The aim of the Convention on Biological Diversity is 'the conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources. The convention stipulates that Parties must :.

Loss of biodiversity occurs when either the habitat essential for the survival of a species is destroyed, or particular species are destroyed. The former is more common as habitat destruction is a fallout of development. The latter reason is encountered when particular species are exploited for economical gain or hunted for sport or food. Extinction of species may also be due to environmental factors like ecological substitutions, biological factors and pathological causes which can be caused by nature or man.

Natural causes include floods, earthquakes, landslides, natural competition between species, lack of pollination and diseases.

Project Tiger was initiated as a Central Sector Scheme in with 9 tiger reserves located in different habitat types in 9 different states. There are totally 18 Reserves in 13 states. At present tiger Conservation has been viewed in India not only as an effort to save an endangered species but, with equal importance, also as a means of preserving biotypes of sizeable magnitude. The main objective was to protect the three endangered species of crocodiles namely - Gavialis gangeticus, Crocodylus palustris and the salt water crocodile, Crocodylus porosus.

The project was launched in with the assistance of WWF in India for conservation of four species of lesser cats e. This was launched in in Manipur to save the brow-antlered deer Cerevus eldi eldi which is on the verge of extinction. The habitat includes 35 sq.

The population of the deer has increased from 18 to It was launched in to protect the Asiatic elephant which is also a highly endangered species because of large scale poaching. It was launched in in Kaziranga Wildlife Sanctuary in Assam to save the lesser one horned rhinoceros from extinction.

It covers an area of sq. This was launched in to save the endangered musk deer which is facing extinction. Captive breeding has yielded good results. This project was launched in in Kashmir valley to save the highly endangered Kashmir stag Cerevus elaphus hanglu which is facing extinction. As a result their population has increased.

Objectives and advantages of biodiversity conservation Conservation of biological diversity leads to conservation of essential ecological diversity to preserve the continuity of food chains.

The genetic diversity of plants and animals is preserved. It ensures the sustainable utilisation of life support systems on earth. It provides a vast knowledge of potential use to the scientific community. A reservoir of wild animals and plants is preserved, thus enabling them to be introduced, if need be, in the surrounding areas. Biological diversity provides immediate benefits to the society such as recreation and tourism. Biodiversity conservation serves as an insurance policy for the future.

Types of conservation Ex situ conservation Conserving biodiversity outside the areas where they naturally occur is known as ex situ conservation. In situ conservation Conserving the animals and plants in their natural habitats is known as in situ conservation. This includes the establishment of National parks and sanctuaries Biosphere reserves Nature reserves Reserved and protected forests Preservation plots Reserved forests Agrobiodiversity conservation After the introduction of cotton, tobacco, sugarcane, sunflower, soyabean and so on, farmers became victims of monocultures in their greed for money.

Convention of Biological Diversity The aim of the convention is to save species and plants from extinction and their habitats from destruction. Key points from the Convention on Biological Diversity The aim of the Convention on Biological Diversity is 'the conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources.

The major causes for biodiversity loss Loss of biodiversity occurs when either the habitat essential for the survival of a species is destroyed, or particular species are destroyed.

Natural causes for the loss of biodiversity Natural causes include floods, earthquakes, landslides, natural competition between species, lack of pollination and diseases. Man-made causes for the loss of biodiversity Destruction of habitat in the wake of developmental activities like housing, agriculture, construction of dams, reservoirs, roads, railway tracks, etc.

Pollution, a gift of the industrial revolution can be given the pride of place for driving a variety of species in air, water and land towards extinction.

Motorcars, air-conditioners and refrigerators, the three symbols of a modern, affluent society, have been instrumental in global warming and ozone depletion.

They have drastically altered the climate with disastrous effects on the various species. Factories and power stations spewing out poisonous gases and effluents have fouled up the environment bringing death and disease to many species.

Oil spills and discharge of sewage have ravaged the oceans and coastal habitats. A large number of species are threatened by overhunting, poaching and illegal trade. Indiscriminate use of toxic chemicals and pesticides and overexploitation of wildlife resources for commercial purposes are responsible for the rapid decline in the number of some species.

The tiger for instance is hunted for its claws and other parts believed to be effective cures for various ailments of man. Snakes and crocodiles are killed in large numbers for their skin and minks, sable, ermine, etc. Genetic erosion arises from the loss due to commercial and anthropogenic pressures of habitats rich in biodiversity and from the disappearance of the traditional conservation practices of wild species in their habitats by rural and tribal people. Projects to save threatended species Project Tiger Project Tiger was initiated as a Central Sector Scheme in with 9 tiger reserves located in different habitat types in 9 different states.

Lesser Cats Project The project was launched in with the assistance of WWF in India for conservation of four species of lesser cats e. The Manipur Brow-antlered Deer Project This was launched in in Manipur to save the brow-antlered deer Cerevus eldi eldi which is on the verge of extinction. Project Elephant It was launched in to protect the Asiatic elephant which is also a highly endangered species because of large scale poaching.

Project Rhino It was launched in in Kaziranga Wildlife Sanctuary in Assam to save the lesser one horned rhinoceros from extinction. Himalayan musk deer project This was launched in to save the endangered musk deer which is facing extinction.

The Definition

Because of these characteristics, biodiversity plays a fundamental role in maintaining the aesthetic value of the environment, the integrity of the natural environment, and promotes the overall well-being of all plant and animal life. This calls for the need for biodiversity conservation for the survival of all living things and their natural habitat. We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity. A single species of organisms with diverse genetic diversity portray more adaptability and survival mechanism against adverse environmental conditions compared to organisms of a single species with the same genetic make-up. Species diversity refers to the variety of organisms in the environment. They can be further subdivided into:.


diversity in nature, but we could lose all that wealth in less than two centuries if the present rates of species losses continue. Biodiversity and its conservation are​.

Biodiversity

Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level.

Biodiversity: Types, Importance and Conservation Methods (with diagram)

Biodiversity is considered as a reservoir of resources to be used for the manufacture of food, medicine, industrial products, etc. BNAT; Classes. The demarcation of biodiversity in each area is determined on the basis of climatic and physiological conditions. The different factors responsible for causing threat to biodiversity are as follows: The primary cause of loss of biodiversity is habitat loss or destruction which is resulted due to the large industrial and commercial activities associated with agriculture, irrigation, construction of dams, mining, fishing etc. NCERT Solutions Science … The factors which are detrimental to the existence of species concerned are eliminated by suitable mechanism. The protection and management of biodiversity through in situ conservation involve certain specific areas known as protected areas which include national parks, Sanctuaries and Biosphere reserves.

The term biodiversity was coined as a contraction of biological diversity by E. Wilson in Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. In other words, biodiversity is the occurrence of different types of ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, environments along with their interactions and processes.
