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. Some of the examples of ex-situ conversation are gene banks, germplasm banks, seed banks. Ex-situ biodiversity conservation aims to reduce the ongoing extinction up to 30% or higher by … Created by: Bhansongal98; Created on: 21-04-16 13:46; Advantages and Disadvantages of ex situ conservation. It relates varieties of habitats, biotic communities ecological processes in biosphere. Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. It is one of two basic conservation strategies, alongside in-situ conservation. 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. 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. 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. (a) The favourable conditions may not be maintained always. (iii) It has 50,000 known species of insects which include 13,000 butterflies and moths. 5.1. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. 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. The activities like harvesting of timbers, collection of forest products, cultivation of lands etc. Seed banking has considerable advantages over other methods of ex situ plant … zoos, seed banks, captive breeding), the notion of in-situ conservation covers a broad • The activities like grazing forestry, cultivation and habitat manipulation are not permitted in these areas. Biodiversity must be seen in the light of holding ethical value. Ex-situ methods focus on species conservation in botanic gardens, zoos, gene banks, and captive breeding programs. Please enable Cookies and reload the page. we save the entire forest to save the tiger. show ecosystem diversity. are permitted as long as these do not interfere with the project. 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. Biodiversity has the following uses for the development humanity: (ii) It provides fibers, sources for the preparation of clothes. Examples of In situ Conservation National Parks, Wild Life sanctuaries, Biosphere Reserves, Gene Sanctuaries Examples of Ex situ Conservation (a. Which one of the following is not a site for in-situ method of conservation of flora? (10) Public awareness should be created regarding biodiversity and its importance for the living organisms. 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. Biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence. (2) All the economically important organisms in protected areas should be identified and conserved. These are scientifically managed allowing only the tourists to visit. Here, animals and plants are reared or cultivated in areas like zoological or botanical parks. (16) Environmental laws should be strictly followed. All of the ex situ conservation methods discussed have their role to play in modern conservation. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. 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… (i) Long-term captive breeding and propagation for the species which have lost their habitats permanently. That is, controlled biotic interference is permitted in sanctuaries, which allows visiting of tourists for recreation. Class 7. Such type of diversity can generate more productive and stable ecosystems or communities capable of tolerating various types of stresses e.g. (7) The poaching and hunting of wildlife should be prevented as far as practicable. (v) Advanced technology in the service of endangered 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. The conservation of species in their natural habitat or natural ecosystem is known as in situ conservation. © 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. 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. Biodiversity is considered as a reservoir of resources to be used for the manufacture of food, medicine, industrial products, etc. Stay tuned with BYJU’S to explore … There are 37,000 protected areas throughout the world. Conserving … The hot spots are determined considering four factors: (iii) Degrees of threat to habitat due to its degradation and fragmentation and. These facilities provide not only housing and care for specimens of endangered species, but also have an educational value. 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. 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. It offers an insurance technique for other methods of conservation. There are two types of conservation methods namely in-situ and ex-situ conservations. This be easily understood by observing detrimental effects of global warming and acid rain which cause an unfavorable alteration in logical processes. (v) It provides different drugs and medicines which are based on different plant products. For example, the landscapes like grass lands, deserts, mountains etc. Ex situ conservation means conservation which takes place off-site. It is seen that the diverse living forms of the ecosystem are modulated with the global environmental changes. (c) Captivity breed species can again be reintroduced in the wild. Organisms are completely protected from predation and poaching; Halth of individuals can be monitored and medical assistance given as required; Populations can be more effectively managed … zoo, aquarium, botanical garden etc. But with an increased demand of rapid population growth, biodiversity is gradually depleting. … (14) The useful animals, plants and their wild relatives should be protected both in their natural habitat (in-situ) and in zoological botanical gardens (ex-situ). In situ conservation involves the conservation of the whole ecosystem and the natural habitats. Ex-situ (‘off site’) conservation techniques are implemented away from the conservation target's natural habitat. (5) There should be sustainable utilisation of resources. A number of plants” and ani­mal species have already become extinct and many are endan­gered. (vi) Several crops arose in the country and spread throughout the world. It is the methods of conserving all the living species in the artful habitats that reflect their natural living habitats. It is especially adapted to species which cannot be established or regenerated outside their natural habitats. Class 6. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Performance & security by Cloudflare, Please complete the security check to access. (b) The main role of these reserves is to preserve genetic resources, species, ecosystems, and habitats without disturbing the habitants. (3) Critical habitats for each species should be identified and safeguarded. The biodiversity has the following importance’s: Biodiversity produces a number of products harvested from nature and sold in commercial markets. The in situ conservation method is the protection and maintenance of species populations in the ecosystem in which they occur. Ex-situ techniques include: seed storage, captive breeding, slow-growth storage, DNA storage. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. These are the areas where only wild animals (fauna) are present. (viii) The marine biota includes sea weeds, fishes, crustaceans, molluses, corals, reptiles etc. Ex situ conservation methods also encourage captive breeding to boost the member counts of species and prevent extinction. Biodiversity Conservation. It involves the in-situ and ex-situ methods. 4.3 Explain how in situ and ex situ conservation methods are used to maintain biodiversity. (c) To make sustainable utilisation of species and ecosystems. (iv) It has 10 different biogeographical regions and 25 biotic provinces having varieties of lands and species. The area under a sanctuary remains in between 0.61 to 7818 km. 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. The in-situ concept is best understood in contrast to ex-situ conservation. While the identification of ex-situ initiatives leaves little room for ambiguity (e.g. It describes diversity of habitat over a total land escape or geographical area. (iv) It provides new varieties of rice, potato etc. Hot spots are the areas with high density of biodiversity or mega diversity which are most threatened at present. All these factors together may be responsible for the extinction of a number of species. through the process of hybridization. (b) Genetic techniques can be utilised in the process. This approach is called in in-situ (on site) conservation. (15) Efforts should be made for setting up of National parks and wild life sanctuaries to safeguard the genetic diversity and their continuing evolution. (6) International trade in wild life should be highly regulated. Biodiversity can be conserved by In Situ and Ex Situ conservation. Protected areas include national parks, sanctuaries and biosphere reserves. 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. Thus, it is rightly told, survival of the man depends upon the survival of the biosphere. compel the human beings to preserve them. 3.5 / 5 based on 10 ratings? Similarly botanical and zoological gardens are the means of biodiversity conservation and are of aesthetic values. (d) These support education and research in various ecological aspects. (ii) Short-term propagation and release of the animals in their natural habitat. 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. It describes the assemblage and Interaction of spices living together and the physical environment a given area. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. Register at BYJU’S to explore biodiversity conservation notes. Class 8. Since earth is homeland of all living organisms, all have equal right to coexist on the surface of earth with all benefits. That is, the conservation of selected plants and animals in se­lected areas outside their natural habitat is known as ex-situ con­servation. Ex-Situ Conservation 2. As per World Conservation Monitoring Centre, India has 581 protected areas, national parks and sanctuaries. There are basically two methods used in forest genetic resource conservation, namely the in situ (on site) and the ex situ (off site) conservation methods.. Terms of Service Privacy Policy Contact Us. Unless some legal value is attached to biodiversity, it will not be possible to protect the rapid extinction of species. There are about 89 national parks in India. Ex-situ conservation involves maintenance and breeding of endangered plants and animals under partially or wholly control­led conditions in specific areas like zoo, gardens, nurseries etc. In these areas, hunting, firewood collection, timber harvesting etc. 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. In-situ and Ex-situ Conservation Methods. The richness of a species tells about the extent of biodiversity of a site and provides a means for comparing different sites. Types of Biodiversity: There are three interrelated hierarchical levels of biodiversity namely, genetic … There are two Methods of biodiversity conservation. 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. Out of the above species, 134781 are residing in India although surface area of India is 2% of the earth’s surface. 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. (v) In addition to geographical distribution, geological events in the land mass provide high level of biological diversity. All these services together are valued 16.54 trillion dollars per year. 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. Indirectly it provides economic benefits to people which include water quality soil protection, equalisation of climate, environmental monitoring, scientific research, recreation etc. The number of individuals of different species with in a region represents species evenness or species equitability. 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. Ex situ conservation Conserving biodiversity outside the areas where they naturally occur is known as ex situ conservation. The product species richness and species evenness give species diversity of a region. (vii) There is wide variety of domestic animals like cows, buffaloes, goats, sheep, pigs, horses etc. Ex-situ Conservation of Biodiversity comprises of aquariums, botanical gardens, Cryopreservation, DNA banks, zoos, etc. Refer to these notes for reference. 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. The species richness depends largely on climatic conditions. Wilson in 1985. Ex Situ Conservation Methods Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. The different advantages of ex-situ conservation are: (a) It gives longer life time and breeding activity to animals. In situ (conservation in the original habitat) is a priority and an advantage over ex situ (non-habitat conservation) methods. Another way to prevent getting this page in the future is to use Privacy Pass. Biodiversity has great economic value because economic development depends upon efficient and economic management of biotic resources. (vi) It is very essential for natural pest control, maintenance of population of various species, pollination by insects and birds, nutrient cycling, conservation and purification of water, formation of soil etc. Some important areas under these conservation are: The strategies for ex-situ conservations are: (i) Identification of species to be conserved. Some important sanctuaries of Orissa are as follows: Biosphere reserves or natural reserves are multipurpose protected areas with boundaries circumscribed by legislation. Refer to protected areas and/or reserves, seed banks, botanic gardens, zoos, sperm banks . (c) This technique involves only few species. The biosphere reserve net work was intro­duced by UNESCO 1971. A number of wildlife species are becoming extinct due to poaching and hunting. )Biosphere Reserve (b.) The boundaries are well demarcated and circumscribed. Table 5.1: Endangered and Endemic Species of India. The demarcation of biodiversity in each area is determined on the basis of climatic and physiological conditions. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. 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. 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. The different advantages of in situ conservation are as follows: (a) If is a cheap and convenient way of conserving biological diversity. (b) To preserve the diversity of species. living in a wide range of ecosystems. Cloudflare Ray ID: 612990e99c550662 The ex-situ conservation involves the strategic protection of biodiversity hotspots for endangered species and habitats. The loss of biodiversity directly influences the social life of the country possibly through influencing ecosystem functions (energy flow and biogeochemical cycle). In Situ Conservation Methods. 3. Ex situ conservation 1. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. (iii) It provides different types of oil seeds for the preparation of oils. The isolated fragment of habitats restricts the potential of species for dispersal and colonization. You may need to download version 2.0 now from the Chrome Web Store. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. It describes a range of communities due to replacement of species which arises due to the presence of different microhabitats, niches and environmental conditions. Continue . The shifting or Jhum cultivation by poor tribal people greatly affects the forest structure which is a store house of biodiversity. According to Whittaker (1965), the community diversities are of three types: It tells the species diversity in a given community. The process of protecting biodiversity at all levels by conserving and protecting the whole ecosystem is called in situ conservation. Mainly the conservation of biodiversity has three basic objectives: (a) To maintain essential ecological processes and life supporting systems. 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. 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 is a set of conservation techniques involving the transfer of a target species away from its native habitat. 1. (First national Park), (iii) Koziranga national Park, Jorhat, Assam, (v) Hazaribagh national Park, Hazaribagh, Bihar, (ix) Reibul Lamjao National Park, Manipur. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Biodiversity holds great ecological value because it is indispensable to maintain the ecological balance. In-situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity. 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. 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) … The stresses on living organisms due to competition for food, water, space etc. It also tells about the diversity within the ecosystem. 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 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. Ex-situ conservation includes off-site collection and gene banks. In recent years ex situ conservation has advanced beyond keeping threatened species. Ex situ conservation is conserving the animals and plant outside the natural habitat. Let us discuss the different conservation methods along with their importance. This was brief information to the Biodiversity, their types and the importance. (c) These maintain cultural, social and ecologically sustainable economic developments. Reintroduction of an animal or plant into the habitat from where it has become extinct is another form of ex situ conservation. (13) The over exploitation of useful products of wild life should be prevented. With increased population, the habitats are fragmented into pieces by roads, fields, canals, power lines, towns etc. 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. 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. (8) Care should be taken for the development of reserves and protected areas. 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… As per available data, the varieties of species living on the earth are 1753739. 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. Advantages. 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. In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) What is Ex-situ Conservation? The natural resources are over exploited to meet growing rural poverty, intensive technological growth and globalization of economy. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. Ex-situ conservation: This method refers to the conservation of biodiversity in the areas outside their natural habitat such as zoos and botanical gardens. Ex situ conservation is the conservation of selected rare plants or animals in places outside the natural forms. The main objective of ex situ techniques is to support conservation by ensuring the survival of threatened species and the maintenance of associated genetic diversity. Generally, they are more expensive to maintain and should be regarded as complementary to in situ conservation methods. Simlipal, (Orissa), Sunderban (West Bengal), Kanha (M.P Kaziranga (Assam) etc. Share these Notes with your friends Prev Next > You can check our 5-step learning process. ... eggs can be fertilized in vitro, and plants can be propagated using tissue culture methods. Some important national Parks of India are: (i) Biological Park, Nandankanan, Orissa, (ii) Corbett national Park Nainital, U.P. 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. Ex situ conservation means the conservation of components of biological diversity outside their natural habitats. 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. (4) Priority should be given to preserve unique ecosystems. In-situ methods use conservation areas as "warehouses" of biological information. Consequently, some 25 years ago, alternative in vitro approaches were considered. This field is for validation purposes and should be left unchanged. 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. These are maintained by government. Botanical gardens, and zoosare the most conventional methods of Ex-situ conservation. are prohibited so that the wild plants and animals can grow and multiply freely without any hindrance. Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. Seeds of different genetic strains of commercially important plants can be kept for … which may be consumed locally and do not figure in national and international market. (ii) It has 350 different mammals, 1200 species of birds- 453 different reptiles, 182 amphibians and 45,000 plants spices. These are the small reserves meant for the protection of wild life and their natural habitats. It depends upon species richness and evenness. Since the animals are more vulnerable to infection, the anthropological activities may increase the incidence of diseases in wild species, leading to their extinction. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities.
