Ex situ conservation methods also encourage captive breeding to boost the member counts of species and prevent extinction. (8) Care should be taken for the development of reserves and protected areas. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. are prohibited so that the wild plants and animals can grow and multiply freely without any hindrance. Terms of Service Privacy Policy Contact Us. Ex situ conservation means the conservation of components of biological diversity outside their natural habitats. The shifting or Jhum cultivation by poor tribal people greatly affects the forest structure which is a store house of biodiversity. through the process of hybridization. Reintroduction of an animal or plant into the habitat from where it has become extinct is another form of ex situ conservation. This was brief information to the Biodiversity, their types and the importance. 4.3 Explain how in situ and ex situ conservation methods are used to maintain biodiversity. It describes diversity of habitat over a total land escape or geographical area. The consumptive value can be assigned to goods such as fuel woods, leaves, forest products etc. Out of the above species, 134781 are residing in India although surface area of India is 2% of the earth’s surface. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. Hot spots are the areas with high density of biodiversity or mega diversity which are most threatened at present. 3. (b) It offers a way to preserve a large number of organisms simultaneously, known or unknown to us. (c) Captivity breed species can again be reintroduced in the wild. Types of Biodiversity: There are three interrelated hierarchical levels of biodiversity namely, genetic … In recent years ex situ conservation has advanced beyond keeping threatened species. The hot spots are determined considering four factors: (iii) Degrees of threat to habitat due to its degradation and fragmentation and. In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) Ex-situ techniques include: seed storage, captive breeding, slow-growth storage, DNA storage. It also tells about the diversity within the ecosystem. Refer to these notes for reference. Biodiversity must be seen in the light of holding ethical value. 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. Its conservation embraces maintenance, sustainable utilization, and restoration, of the lost and degraded biodiversity through two basic and complementary strategies called in situ and ex situ. Since earth is homeland of all living organisms, all have equal right to coexist on the surface of earth with all benefits. This field is for validation purposes and should be left unchanged. Such type of diversity can generate more productive and stable ecosystems or communities capable of tolerating various types of stresses e.g. Please enable Cookies and reload the page. The isolated fragment of habitats restricts the potential of species for dispersal and colonization. In Situ Conservation Methods. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. 5.1. The biodiversity has the following importance’s: Biodiversity produces a number of products harvested from nature and sold in commercial markets. living in a wide range of ecosystems. It involves the in-situ and ex-situ methods. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. The factors which are detrimental to the existence of species concerned are eliminated by suitable mechanism. Which one of the following is not a site for in-situ method of conservation of flora? The main aim of biosphere reserve is to preserve genetic diversity in representative ecosystems by protecting wild animals, traditional life style of inhabitant and domesticated plant/ animal genetic resources. Register at BYJU’S to explore biodiversity conservation notes. It is referred as Land escape diversity because it includes placement and size of various ecosystems. It is especially adapted to species which cannot be established or regenerated outside their natural habitats. Let us discuss the different conservation methods along with their importance. Ex situ conservation 1. (7) The poaching and hunting of wildlife should be prevented as far as practicable. Class 8. (5) There should be sustainable utilisation of resources. Ex situ conservation methods ened in situ and is the for the conservation of the specific genetic resource, Frequently, the will be to establish populations that maintain as much as possible of the original and allows for long-term tion to the local conditions at the planting site. In-situ and Ex-situ Conservation Methods. The different advantages of in situ conservation are as follows: (a) If is a cheap and convenient way of conserving biological diversity. (v) It provides different drugs and medicines which are based on different plant products. (16) Environmental laws should be strictly followed. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. These are maintained by government. The introduction of exotic species are due to: It is seen that some exotic species may kill or eat the native species thereby causing its extinction. The activities like harvesting of timbers, collection of forest products, cultivation of lands etc. All these factors together may be responsible for the extinction of a number of species. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its form and good health for the future generation i.e., the human being should prevent the degradation and destruction of the habitats thereby maintaining the biodiversity at its optimum level. Consequently, some 25 years ago, alternative in vitro approaches were considered. (2) All the economically important organisms in protected areas should be identified and conserved. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. Also in ex- situ conservation, all of which house whole, protected specimens for breeding and reintroduction into the wild when necessary and possible. (12) The habitats of migratory birds should be protected by bilateral and multilateral agreement. 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. It is the methods of conserving all the living species in the artful habitats that reflect their natural living habitats. (15) Efforts should be made for setting up of National parks and wild life sanctuaries to safeguard the genetic diversity and their continuing evolution. The following strategies should be undertaken in order to con­serve biodiversity: (1) All the possible varieties (old or new) of food, forage and timber plants, live stock, agriculture animals and microbes should be conserved. Performance & security by Cloudflare, Please complete the security check to access. The different advantages of ex-situ conservation are: (a) It gives longer life time and breeding activity to animals. These facilities provide not only housing and care for specimens of endangered species, but also have an educational value. • These are scientifically managed allowing only the tourists to visit. Botanical gardens, and zoosare the most conventional methods of Ex-situ conservation. Ex situ conservation is conserving the animals and plant outside the natural habitat. In this method of biological diversity conservation, sampling, shifting, storage and preservation of target taxa is carried out outside the natural habitat of the organisms. (iv) It provides new varieties of rice, potato etc. Similarly botanical and zoological gardens are the means of biodiversity conservation and are of aesthetic values. (vi) Several crops arose in the country and spread throughout the world. These are the small reserves meant for the protection of wild life and their natural habitats. It describes the assemblage and Interaction of spices living together and the physical environment a given area. The in situ conservation method is the protection and maintenance of species populations in the ecosystem in which they occur. The natural resources are over exploited to meet growing rural poverty, intensive technological growth and globalization of economy. Ex-situ Conservation of Biodiversity comprises of aquariums, botanical gardens, Cryopreservation, DNA banks, zoos, etc. The species richness depends largely on climatic conditions. 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. Simlipal, (Orissa), Sunderban (West Bengal), Kanha (M.P Kaziranga (Assam) etc. Mainly the conservation of biodiversity has three basic objectives: (a) To maintain essential ecological processes and life supporting systems. Ex-Situ Conservation 2. (ii) Adoption of Different ex-situ methods of conservation. Conservation of biodiversity is protection, upliftment and scientific management of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation. The ex-situ conservation involves the strategic protection of biodiversity hotspots for endangered species and habitats. 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. Also Read: Vegetative Propagation. (a) The favourable conditions may not be maintained always. It is one of two basic conservation strategies, alongside in-situ conservation. You may need to download version 2.0 now from the Chrome Web Store. Your IP: 185.2.5.12 Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. There are about 89 national parks in India. In-situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity. A number of wildlife species are becoming extinct due to poaching and hunting. The diversity may be interspecific (within species) and interspecific (in between the species) but these are well supported by ecosystem. Thus, it is rightly told, survival of the man depends upon the survival of the biosphere. Biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence. Ex-situ (‘off site’) conservation techniques are implemented away from the conservation target's natural habitat. These are the areas where only wild animals (fauna) are present. Indirectly it provides economic benefits to people which include water quality soil protection, equalisation of climate, environmental monitoring, scientific research, recreation etc. The activities like grazing forestry, cultivation and habitat manipulation are not permitted in these areas. So, it is highly essential for the human beings to take care of their surrounding species and make optimum use of their service, for better economic development. In other words, conservation of bio-diversity is the proper management of the biosphere by human beings in such a way that it gives maximum benefits for the present generation and also develops its potential so as to meet the needs of the future generations. Generally, they are more expensive to maintain and should be regarded as complementary to in situ conservation methods. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. The boundaries are well demarcated and circumscribed. Examples of In situ Conservation National Parks, Wild Life sanctuaries, Biosphere Reserves, Gene Sanctuaries Examples of Ex situ Conservation 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. Class 7. Refer to protected areas and/or reserves, seed banks, botanic gardens, zoos, sperm banks . biodiversity conservation method mainly insitu and exsitu conservation methods .several insitu conservation methods are used to conserve several endangered organisms.the slide for excellent view use power point 2013 version. (iii) It provides different types of oil seeds for the preparation of oils. It offers an insurance technique for other methods of conservation. Protected areas include national parks, sanctuaries and biosphere reserves. In situ conservation involves the conservation of the whole ecosystem and the natural habitats. are permitted as long as these do not interfere with the project. we save the entire forest to save the tiger. Seed banking has considerable advantages over other methods of ex situ plant … 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… (ii) It has 350 different mammals, 1200 species of birds- 453 different reptiles, 182 amphibians and 45,000 plants spices. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. © 2017 EnvironmentalPollution - All rights reserved, Essay on Wildlife Conservation (671 Words), Biodiversity: Meaning, Varieties and Scenario in India, Radiation Pollution: Types, Sources, Effects, Control of Radiation Pollution, Causes of Water Pollution in India (7 Answers), Causes of Water Pollution: Essay, Paragraph, Article and Speech. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic spices, diseases, shifting cultivation, poaching of wild life etc. For example, the Gangetic gharial has been reintroduced in the rivers of Uttar Pradesh, Madhya Pradesh and Rajasthan where it had become extinct. While the identification of ex-situ initiatives leaves little room for ambiguity (e.g. (b) The main role of these reserves is to preserve genetic resources, species, ecosystems, and habitats without disturbing the habitants. Some protected areas are: Cold desert (Ladakh and Spiti), Hot desert (Thar), Saline Swampy area (Sunderban and Rann of Kutch), Tropical moist deciduous forest (Western Ghats and north East) etc. The main difference between in situ and ex situ is that the in situ refers to the original location whereas the ex situ refers to the off-site.Furthermore, in situ methods are less expensive and less manageable while the ex situ methods are expensive and manageable. (c) These maintain cultural, social and ecologically sustainable economic developments. All of the ex situ conservation methods discussed have their role to play in modern conservation. (ix) There are a number of hot spots (namely Eastern Ghats, Western Ghats, North Eastern hills etc.). There are 16 hot spots in world, out of which two are located in India namely North-East Himalayas and Western Ghats. The ecosystem diversity is due to diversity of niches, trophic levels and ecological processes like nutrient cycling, food webs, energy flow, role of dominant species and various related biotic interactions. 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. Definition: Ex-Situ means literally, "off-site conservation“ the process of protecting an endangered species of plant or animal outside of its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans. There are two Methods of biodiversity conservation. Category Enlisted species Highly endangered Species. The species richness may be defined as the number of species per unit area. Biodiversity has great economic value because economic development depends upon efficient and economic management of biotic resources. As per available data, the varieties of species living on the earth are 1753739. Gametes of threatened species can be preserved in viable, fertile conditions for long periods using cryopreservation techniques, eggs can be fertilised in vitro, and plants can be propagated using tissue culture methods. The product species richness and species evenness give species diversity of a region. Biodiversity can be conserved by In Situ and Ex Situ conservation. There are 37,000 protected areas throughout the world. What is Ex-situ Conservation? A number of plants” and ani­mal species have already become extinct and many are endan­gered. Cloudflare Ray ID: 612990e99c550662 Biodiversity Conservation. (10) Public awareness should be created regarding biodiversity and its importance for the living organisms. The conservation of species in their natural habitat or natural ecosystem is known as in situ conservation. (c) To make sustainable utilisation of species and ecosystems. Seeds of different genetic strains of commercially important plants can be kept for … Here, animals and plants are reared or cultivated in areas like zoological or botanical parks. For example they may be the only option where in situ conservation is no longer possible. (a. (b) To preserve the diversity of species. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. The in-situ concept is best understood in contrast to ex-situ conservation. The magnitude of variation in genes of a species increases with increase in size and environmental parameters of the habitat. Biodiversity is considered as a reservoir of resources to be used for the manufacture of food, medicine, industrial products, etc. Any disturbance in the delicately fabricated ecological balance maintained by different organisms, will lead to severe problems, which may threaten the survival of human beings. However, when there are situations where an animal or plant is endangered or threatened and needs urgent measures to save it from extinction, ex-situ (off-site) … Identification and protection of endangered species. compel the human beings to preserve them. (b) Genetic techniques can be utilised in the process. Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. In these areas, hunting, firewood collection, timber harvesting etc. Table 5.1: Endangered and Endemic Species of India. (d) These support education and research in various ecological aspects. zoos, seed banks, captive breeding), the notion of in-situ conservation covers a broad (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. Classes. (13) The over exploitation of useful products of wild life should be prevented. In addition, the habitat fragmentation also brings about microclimatic changes in light, temperature, wind etc. The process of protecting biodiversity at all levels by conserving and protecting the whole ecosystem is called in situ conservation. In the process, the natural surrounding or ecosystem is protected and maintained so that all the constituent species (known or unknown) are conserved and benefited. Wild life Institute of India has divided it into ten biogeographical regions and twenty five biotic provinces. The number of individuals of different species with in a region represents species evenness or species equitability. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. • It depends upon species richness and evenness. Unless some legal value is attached to biodiversity, it will not be possible to protect the rapid extinction of species. As per World Conservation Monitoring Centre, India has 581 protected areas, national parks and sanctuaries. (9) Efforts should be made to reduce the level of pollutants in the environment. There are two types of conservation methods namely in-situ and ex-situ conservations. The protected areas are biogeographical areas where biological diversity along with natural and cultural resources are protected, maintained and managed through legal and administrative measures. (v) Advanced technology in the service of endangered species. The richness of a species tells about the extent of biodiversity of a site and provides a means for comparing different sites. Ex-situ biodiversity conservation aims to reduce the ongoing extinction up to 30% or higher by … 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. (c) This technique involves only few species. The most dreaded factor inducing loss of biodiversity is environmental pollution which include air pollution, Water pollution, industrial pollution, pollution due to chemical Pastes, pesticides radioactive materials etc. It describes the variety in the number and richness of the spices with in a region. (4) Priority should be given to preserve unique ecosystems. In the day to day life, human beings are maintaining their lifestyle at the sacrifice of surrounding species which come from diversity of plants and animals struggling for their existence. (viii) The marine biota includes sea weeds, fishes, crustaceans, molluses, corals, reptiles etc. The demarcation of biodiversity in each area is determined on the basis of climatic and physiological conditions. (3) Critical habitats for each species should be identified and safeguarded. The genetic variation arises by gene and chromosome mutation in individuals and in sexually reproducing organisms and it is spread in the population by recombination of genetic materials during cell division after sexual reproduction. Seedbanks, botanical, horti… The term biodiversity was coined as a contraction of biological diversity by E.O. 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. 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. 3.5 / 5 based on 10 ratings? (ii) Short-term propagation and release of the animals in their natural habitat. 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. That is, controlled biotic interference is permitted in sanctuaries, which allows visiting of tourists for recreation. For example, the landscapes like grass lands, deserts, mountains etc. (11) Priority should be given in wildlife conservation programme to endangered species over vulnerable species and to vulnerable species over rare species. 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 … 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. show ecosystem diversity. Some important national Parks of India are: (i) Biological Park, Nandankanan, Orissa, (ii) Corbett national Park Nainital, U.P. (First national Park), (iii) Koziranga national Park, Jorhat, Assam, (v) Hazaribagh national Park, Hazaribagh, Bihar, (ix) Reibul Lamjao National Park, Manipur. (iv) It has 10 different biogeographical regions and 25 biotic provinces having varieties of lands and species. 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. 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 means conservation which takes place off-site. Biodiversity holds great ecological value because it is indispensable to maintain the ecological balance. All these services together are valued 16.54 trillion dollars per year. This be easily understood by observing detrimental effects of global warming and acid rain which cause an unfavorable alteration in logical processes. Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI). In situ and ex situ are two methods used to describe different biological processes such as bioremediation, and conservation of … ... eggs can be fertilized in vitro, and plants can be propagated using tissue culture methods. (6) International trade in wild life should be highly regulated. It relates varieties of habitats, biotic communities ecological processes in biosphere. Class 6. When a species is confined entirely to a particular area, it is termed as endemic species. The loss of biodiversity directly influences the social life of the country possibly through influencing ecosystem functions (energy flow and biogeochemical cycle). Another way to prevent getting this page in the future is to use Privacy Pass.
