(5) There should be sustainable utilisation of resources. Protected areas include national parks, sanctuaries and biosphere reserves. In-situ and Ex-situ Conservation Methods. 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 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. (c) This technique involves only few species. 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. These are the small reserves meant for the protection of wild life and their natural habitats. The in situ conservation method is the protection and maintenance of species populations in the ecosystem in which they occur. Another way to prevent getting this page in the future is to use Privacy Pass. (4) Priority should be given to preserve unique ecosystems. (b) The main role of these reserves is to preserve genetic resources, species, ecosystems, and habitats without disturbing the habitants. through the process of hybridization. are permitted as long as these do not interfere with the project. ... eggs can be fertilized in vitro, and plants can be propagated using tissue culture methods. Biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence. Seeds of different genetic strains of commercially important plants can be kept for … That is, controlled biotic interference is permitted in sanctuaries, which allows visiting of tourists for recreation. 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. (7) The poaching and hunting of wildlife should be prevented as far as practicable. Some important national Parks of India are: (i) Biological Park, Nandankanan, Orissa, (ii) Corbett national Park Nainital, U.P. Ex-situ techniques include: seed storage, captive breeding, slow-growth storage, DNA storage. Indirectly it provides economic benefits to people which include water quality soil protection, equalisation of climate, environmental monitoring, scientific research, recreation etc. Created by: Bhansongal98; Created on: 21-04-16 13:46; Advantages and Disadvantages of ex situ conservation. 1. Aesthetic values such as refreshing fragrance of the flowers, taste of berries, softness of mossed, melodious songs of birds, etc. (vii) There is wide variety of domestic animals like cows, buffaloes, goats, sheep, pigs, horses etc. It is referred as Land escape diversity because it includes placement and size of various ecosystems. Biodiversity is considered as a reservoir of resources to be used for the manufacture of food, medicine, industrial products, etc. As per World Conservation Monitoring Centre, India has 581 protected areas, national parks and sanctuaries. 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. There are three interrelated hierarchical levels of biodiversity namely, genetic diversity, species diversity and community or ecosystem diversity. The richness of a species tells about the extent of biodiversity of a site and provides a means for comparing different sites. (c) These maintain cultural, social and ecologically sustainable economic developments. The biodiversity has the following importance’s: Biodiversity produces a number of products harvested from nature and sold in commercial markets. All of the ex situ conservation methods discussed have their role to play in modern conservation. In-situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity. 4.3 Explain how in situ and ex situ conservation methods are used to maintain biodiversity. In addition, the habitat fragmentation also brings about microclimatic changes in light, temperature, wind etc. There are 37,000 protected areas throughout the world. The activities like harvesting of timbers, collection of forest products, cultivation of lands etc. It describes the assemblage and Interaction of spices living together and the physical environment a given area. Which one of the following is not a site for in-situ method of conservation of flora? 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. Since earth is homeland of all living organisms, all have equal right to coexist on the surface of earth with all benefits. 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. According to Whittaker (1965), the community diversities are of three types: It tells the species diversity in a given community. Biodiversity can be conserved by In Situ and Ex Situ conservation. 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. Your IP: 185.2.5.12 These facilities provide not only housing and care for specimens of endangered species, but also have an educational value. In situ conservation involves the conservation of the whole ecosystem and the natural habitats. The activities like grazing forestry, cultivation and habitat manipulation are not permitted in these areas. 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. That is, the conservation of selected plants and animals in selected areas outside their natural habitat is known as ex-situ conservation. (v) It provides different drugs and medicines which are based on different plant products. But with an increased demand of rapid population growth, biodiversity is gradually depleting. In these areas, hunting, firewood collection, timber harvesting etc. 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. 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. 3. Some of the examples of ex-situ conversation are gene banks, germplasm banks, seed banks. Such type of diversity can generate more productive and stable ecosystems or communities capable of tolerating various types of stresses e.g. Refer to protected areas and/or reserves, seed banks, botanic gardens, zoos, sperm banks . The boundaries are well demarcated and circumscribed. Since the animals are more vulnerable to infection, the anthropological activities may increase the incidence of diseases in wild species, leading to their extinction. For example they may be the only option where in situ conservation is no longer possible. zoos, seed banks, captive breeding), the notion of in-situ conservation covers a broad Thus, it is rightly told, survival of the man depends upon the survival of the biosphere. 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 2. There are two types of conservation methods namely in-situ and ex-situ conservations. Out of the above species, 134781 are residing in India although surface area of India is 2% of the earth’s surface. The demarcation of biodiversity in each area is determined on the basis of climatic and physiological conditions. Ex Situ Conservation Methods Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. (iv) It provides new varieties of rice, potato 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. Generally, they are more expensive to maintain and should be regarded as complementary to in situ conservation methods. are prohibited so that the wild plants and animals can grow and multiply freely without any hindrance. 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… Biodiversity Conservation. It depends upon species richness and evenness. Consequently, some 25 years ago, alternative in vitro approaches were considered. The shifting or Jhum cultivation by poor tribal people greatly affects the forest structure which is a store house of biodiversity. Refer to these notes for reference. (9) Efforts should be made to reduce the level of pollutants in the environment. (2) All the economically important organisms in protected areas should be identified and conserved. Some important sanctuaries of Orissa are as follows: Biosphere reserves or natural reserves are multipurpose protected areas with boundaries circumscribed by legislation. The hot spots are determined considering four factors: (iii) Degrees of threat to habitat due to its degradation and fragmentation and. 3.5 / 5 based on 10 ratings? The biosphere reserve net work was introduced by UNESCO 1971. which may be consumed locally and do not figure in national and international market. Hot spots are the areas with high density of biodiversity or mega diversity which are most threatened at present. In-Situ (natural home) 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) compel the human beings to preserve them. (12) The habitats of migratory birds should be protected by bilateral and multilateral agreement. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. 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. 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. 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. Ex-situ (‘off site’) conservation techniques are implemented away from the conservation target's natural habitat. Ex situ conservation means conservation which takes place off-site. Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. In situ (conservation in the original habitat) is a priority and an advantage over ex situ (non-habitat conservation) methods. Botanical gardens, and zoosare the most conventional methods of Ex-situ conservation. Mainly the conservation of biodiversity has three basic objectives: (a) To maintain essential ecological processes and life supporting systems. Types of Biodiversity: There are three interrelated hierarchical levels of biodiversity namely, genetic … Category Enlisted species Highly endangered Species. Ex-situ biodiversity conservation aims to reduce the ongoing extinction up to 30% or higher by … Share these Notes with your friends Prev Next > You can check our 5-step learning process. 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. (First national Park), (iii) Koziranga national Park, Jorhat, Assam, (v) Hazaribagh national Park, Hazaribagh, Bihar, (ix) Reibul Lamjao National Park, Manipur. The ex-situ conservation involves the strategic protection of biodiversity hotspots for endangered species and habitats. The in-situ concept is best understood in contrast to ex-situ conservation. (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. Performance & security by Cloudflare, Please complete the security check to access. As per available data, the varieties of species living on the earth are 1753739. Terms of Service Privacy Policy Contact Us. 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. 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. (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). Class 7. It is seen that the diverse living forms of the ecosystem are modulated with the global environmental changes. 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. Ex situ conservation means the conservation 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. Biodiversity must be seen in the light of holding ethical value. 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. It describes the variety in the number and richness of the spices with in a region. This was brief information to the Biodiversity, their types and the importance. 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… It is especially adapted to species which cannot be established or regenerated outside their natural habitats. Ex-situ Conservation of Biodiversity comprises of aquariums, botanical gardens, Cryopreservation, DNA banks, zoos, etc. In Situ Conservation Methods. The natural resources are over exploited to meet growing rural poverty, intensive technological growth and globalization of economy. (15) Efforts should be made for setting up of National parks and wild life sanctuaries to safeguard the genetic diversity and their continuing evolution. 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. living in a wide range of ecosystems. There are two Methods of biodiversity conservation. 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. Please enable Cookies and reload the page. There are 16 hot spots in world, out of which two are located in India namely North-East Himalayas and Western Ghats. © 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. Such collections are expensive to maintain, are susceptible to environmental changes, and do not present a safe long-term option. It describes a range of communities due to replacement of species which arises due to the presence of different microhabitats, niches and environmental conditions. 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.
