ex situ conservation methods

0 Comment

When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. The living organisms on earth are of great diversity, living in diverse habitats and possessing diverse qualities and are vital to human existence providing food, shelter, clothing’s, medicines etc. These are the areas where only wild animals (fauna) are present. Simlipal, (Orissa), Sunderban (West Bengal), Kanha (M.P Kaziranga (Assam) etc. The consumptive value can be assigned to goods such as fuel woods, leaves, forest products etc. Many scientists and conservationists feel that until methods are available to discern easily which of the millions of species and varieties will have economic value, in-situ conservation through the protection … In-situ methods use conservation areas as "warehouses" of biological information. Ex situ conservation means conservation which takes place off-site. Ex situ conservation means the conservation of components of biological diversity outside their natural habitats. The only disadvantage of in situ conservation is that it requires large space of earth which is often difficult because of growing demand for space. (ii) It has 350 different mammals, 1200 species of birds- 453 different reptiles, 182 amphibians and 45,000 plants spices. (ix) There are a number of hot spots (namely Eastern Ghats, Western Ghats, North Eastern hills etc.). Ex Situ Conservation Methods Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. we save the entire forest to save the tiger. Some important areas under these conservation are: The strategies for ex-situ conservations are: (i) Identification of species to be conserved. The term biodiversity was coined as a contraction of biological diversity by E.O. In addition, the habitat fragmentation also brings about microclimatic changes in light, temperature, wind etc. While the identification of ex-situ initiatives leaves little room for ambiguity (e.g. Biodiversity can be conserved by In Situ and Ex Situ conservation. It relates varieties of habitats, biotic communities ecological processes in biosphere. The hot spots are determined considering four factors: (iii) Degrees of threat to habitat due to its degradation and fragmentation and. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. In-situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity. The discussion on each type of diversity is given below: It describes the variation in the number and types of genes as well as chromosomes present in different species. drought, flood etc. (iii) It provides different types of oil seeds for the preparation of oils. Since man is the most intelligent amongst the living organisms, it should be prime responsibility and moral obligation of man to preserve and conserve other organisms which will directly or indirectly favour the existence of the man. (15) Efforts should be made for setting up of National parks and wild life sanctuaries to safeguard the genetic diversity and their continuing evolution. Hot spots are the areas with high density of biodiversity or mega diversity which are most threatened at present. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. The area of national parks ranges between 0.04 to 3162 km. The term 'method' is often used to denote different concepts such as in situ conservation, ex situ conservation, ecosystem conservation, species conservation, static conservation, dynamic conservation and others. The shifting or Jhum cultivation by poor tribal people greatly affects the forest structure which is a store house of biodiversity. (b) To preserve the diversity of species. These are the small reserves meant for the protection of wild life and their natural habitats. This approach is called in in-situ (on site) conservation. Unless some legal value is attached to biodiversity, it will not be possible to protect the rapid extinction of species. (9) Efforts should be made to reduce the level of pollutants in the environment. Ex-situ conservation, which is also known as off-site conservation, refers to the conservation of endangered species in the artificial or man-made habitats that imitate their natural habitats, e.g. • They inform the public of the threatened status of endangered species and of those factors which cause the threat, with the hope of creating public inte… (v) It provides different drugs and medicines which are based on different plant products. Which one of the following is not a site for in-situ method of conservation of flora? Since the animals are more vulnerable to infection, the anthropological activities may increase the incidence of diseases in wild species, leading to their extinction. Ex-situ conservation: This method refers to the conservation of biodiversity in the areas outside their natural habitat such as zoos and botanical gardens. Biodiversity holds great ecological value because it is indispensable to maintain the ecological balance. Some important national Parks of India are: (i) Biological Park, Nandankanan, Orissa, (ii) Corbett national Park Nainital, U.P. (ii) Adoption of Different ex-situ methods of conservation. Botanical gardens, and zoosare the most conventional methods of Ex-situ conservation. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. When a species is confined entirely to a particular area, it is termed as endemic species. Continue . It is the methods of conserving all the living species in the artful habitats that reflect their natural living habitats. (10) Public awareness should be created regarding biodiversity and its importance for the living organisms. Now gametes of threatened species can be preserved in viable and fertile condition for long periods using cryopreservation techniques, eggs can be fertilized in vitro, and plants can be propagated using tissue culture methods. • The stresses on living organisms due to competition for food, water, space etc. (vi) Several crops arose in the country and spread throughout the world. ... eggs can be fertilized in vitro, and plants can be propagated using tissue culture methods. Advantages and Disadvantages of ex situ conservation. Seeds of different genetic strains of commercially important plants can be kept for … Biodiversity Conservation. (iv) It has 10 different biogeographical regions and 25 biotic provinces having varieties of lands and species. This was brief information to the Biodiversity, their types and the importance. Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. (16) Environmental laws should be strictly followed. There are two types of conservation methods namely in-situ and ex-situ conservations. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. 5.1. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Biodiversity has great economic value because economic development depends upon efficient and economic management of biotic resources. The factors which are detrimental to the existence of species concerned are eliminated by suitable mechanism. Please enable Cookies and reload the page. Ex situ conservation 1. Biodiversity must be seen in the light of holding ethical value. Protected areas include national parks, sanctuaries and biosphere reserves. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) Refer to these notes for reference. Ex situ conservation methods also encourage captive breeding to boost the member counts of species and prevent extinction. The global hot spot and endemic species present within them are: (iii) Cape region of South Africa (6,000); (xii) Californian Floristic Province (2,140); Different mechanisms involved in the conservation of biodiversity is shown in Fig. Biodiversity includes the genetic variability (for which different varieties of spices have appeared in the course of evolution) and diversity of life forms such as plants, animal microbes, etc. What is Ex-situ Conservation? You may need to download version 2.0 now from the Chrome Web Store. There are three interrelated hierarchical levels of biodiversity namely, genetic diversity, species diversity and community or ecosystem diversity. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI). (c) The existence in natural ecosystem provides opportunity to the living organisms to adjust to differed’ environmental conditions and to evolve in to a better life form. It offers an insurance technique for other methods of conservation. (7) The poaching and hunting of wildlife should be prevented as far as practicable. Ex-situ biodiversity conservation aims to reduce the ongoing extinction up to 30% or higher by … All these services together are valued 16.54 trillion dollars per year. The biosphere reserve net work was intro­duced by UNESCO 1971. Similarly botanical and zoological gardens are the means of biodiversity conservation and are of aesthetic values. The demarcation of biodiversity in each area is determined on the basis of climatic and physiological conditions. Ex situ conservation Conserving biodiversity outside the areas where they naturally occur is known as ex situ conservation. The in situ conservation method is the protection and maintenance of species populations in the ecosystem in which they occur. (v) In addition to geographical distribution, geological events in the land mass provide high level of biological diversity. But with an increased demand of rapid population growth, biodiversity is gradually depleting. It is especially adapted to species which cannot be established or regenerated outside their natural habitats. Conserving … Ex-situ Conservation of Biodiversity comprises of aquariums, botanical gardens, Cryopreservation, DNA banks, zoos, etc. The earth’s natural beauty with its colour and hues, thick forest, and graceful beasts has inspired the human beings from their date of birth to take necessary steps for its maintenance. (b) Genetic techniques can be utilised in the process. All of the ex situ conservation methods discussed have their role to play in modern conservation. That is, controlled biotic interference is permitted in sanctuaries, which allows visiting of tourists for recreation. Genetic diversity has the following importance: (i) It helps in speciation or evolution of new species; (ii) It is useful in adaptation to changes in environmental conditions; (iii) It is important for agricultural productivity and development. Here, animals and plants are reared or cultivated in areas like zoological or botanical parks. Ex situ conservation is the technique of conservation of all levels of biological diversity outside their natural habitats through different techniques like zoo, captive breeding, aquarium, botanical garden, an… Category Enlisted species Highly endangered Species. It also tells about the diversity within the ecosystem. are permitted as long as these do not interfere with the project. 3. It involves the in-situ and ex-situ methods.

Some importance of biosphere reserves are as follows: (a) These help in the restoration of degraded ecosystem. Aesthetic values such as refreshing fragrance of the flowers, taste of berries, softness of mossed, melodious songs of birds, etc. Ex-situ (‘off site’) conservation techniques are implemented away from the conservation target's natural habitat. India is one of the twelve mega diversity nations of the world due to the following reasons: (i) It has 7.3% of the global fauna and 10.88% of global flora as per the data collected by Ministry of Environment and forest. Such type of diversity can generate more productive and stable ecosystems or communities capable of tolerating various types of stresses e.g. Efforts should be given in wildlife conservation programme to endangered species table 5.1: endangered and species!
