There are 37,000 protected areas throughout the world. Unless some legal value is attached to biodiversity, it will not be possible to protect the rapid extinction of species. In situ and ex situ are two methods used to describe different biological processes such as bioremediation, and conservation of … Share these Notes with your friends Prev Next > You can check our 5-step learning process. Your IP: 185.2.5.12 (iv) It has 10 different biogeographical regions and 25 biotic provinces having varieties of lands and species. Seeds of different genetic strains of commercially important plants can be kept for … 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 species richness depends largely on climatic conditions. In addition, the habitat fragmentation also brings about microclimatic changes in light, temperature, wind etc. Performance & security by Cloudflare, Please complete the security check to access. Ex situ conservation methods also encourage captive breeding to boost the member counts of species and prevent extinction. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. 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. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. Biodiversity can be conserved by In Situ and Ex Situ conservation. compel the human beings to preserve them. Register at BYJU’S to explore biodiversity conservation notes. (11) Priority should be given in wildlife conservation programme to endangered species over vulnerable species and to vulnerable species over rare species. It offers an insurance technique for other methods of conservation. (i) Long-term captive breeding and propagation for the species which have lost their habitats permanently. In-situ methods use conservation areas as "warehouses" of biological information. (4) Priority should be given to preserve unique ecosystems. (c) To make sustainable utilisation of species and ecosystems. (d) These support education and research in various ecological aspects. Ex-situ conservation includes off-site collection and gene banks. For example, the landscapes like grass lands, deserts, mountains etc. Out of the above species, 134781 are residing in India although surface area of India is 2% of the earth’s surface. It is one of two basic conservation strategies, alongside in-situ conservation. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. That is, controlled biotic interference is permitted in sanctuaries, which allows visiting of tourists for recreation. Ex Situ Conservation Methods Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. are permitted as long as these do not interfere with the project. (13) The over exploitation of useful products of wild life should be prevented. (c) Captivity breed species can again be reintroduced in the wild. (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. 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. (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. Hot spots are the areas with high density of biodiversity or mega diversity which are most threatened at present. It describes a range of communities due to replacement of species which arises due to the presence of different microhabitats, niches and environmental conditions. Ex-situ Conservation of Biodiversity comprises of aquariums, botanical gardens, Cryopreservation, DNA banks, zoos, etc. Seed banking has considerable advantages over other methods of ex situ plant … Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. It relates varieties of habitats, biotic communities ecological processes in biosphere. 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. (v) It provides different drugs and medicines which are based on different plant products. It is referred as Land escape diversity because it includes placement and size of various ecosystems. Reintroduction of an animal or plant into the habitat from where it has become extinct is another form of ex situ conservation. Also in ex- situ conservation, all of which house whole, protected specimens for breeding and reintroduction into the wild when necessary and possible. It describes the variety in the number and richness of the spices with in a region. These facilities provide not only housing and care for specimens of endangered species, but also have an educational value.

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. Another way to prevent getting this page in the future is to use Privacy Pass. The shifting or Jhum cultivation by poor tribal people greatly affects the forest structure which is a store house of biodiversity. 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. Let us discuss the different conservation methods along with their importance. 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. Biodiversity is considered as a reservoir of resources to be used for the manufacture of food, medicine, industrial products, etc. This field is for validation purposes and should be left unchanged. (a. zoo, aquarium, botanical garden etc. 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 conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. (3) Critical habitats for each species should be identified and safeguarded. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. (b) The main role of these reserves is to preserve genetic resources, species, ecosystems, and habitats without disturbing the habitants. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. Refer to protected areas and/or reserves, seed banks, botanic gardens, zoos, sperm banks .

Biodiversity has the following uses for the development humanity: (ii) It provides fibers, sources for the preparation of clothes. (6) International trade in wild life should be highly regulated. Ex-situ methods focus on species conservation in botanic gardens, zoos, gene banks, and captive breeding programs. (16) Environmental laws should be strictly followed. 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. (a) The favourable conditions may not be maintained always. The area under a sanctuary remains in between 0.61 to 7818 km. 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. 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. Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI). You may need to download version 2.0 now from the Chrome Web Store. The area of national parks ranges between 0.04 to 3162 km. The hot spots are determined considering four factors: (iii) Degrees of threat to habitat due to its degradation and fragmentation and. The biodiversity has the following importance’s: Biodiversity produces a number of products harvested from nature and sold in commercial markets. Biodiversity has great economic value because economic development depends upon efficient and economic management of biotic resources. Continue . )Biosphere Reserve (b.)
