Wild life Institute of India has divided it into ten biogeographical regions and twenty five biotic provinces. (b) It offers a way to preserve a large number of organisms simultaneously, known or unknown to us. The isolated fragment of habitats restricts the potential of species for dispersal and colonization. According to Whittaker (1965), the community diversities are of three types: It tells the species diversity in a given community. (10) Public awareness should be created regarding biodiversity and its importance for the living organisms. The natural resources are over exploited to meet growing rural poverty, intensive technological growth and globalization of economy. Refer to these notes for reference. 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. When a species is confined entirely to a particular area, it is termed as endemic species. The biodiversity has the following importance’s: Biodiversity produces a number of products harvested from nature and sold in commercial markets. 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 factors which are detrimental to the existence of species concerned are eliminated by suitable mechanism. )Biosphere Reserve (b.) (d) These support education and research in various ecological aspects. 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. (iii) It provides different types of oil seeds for the preparation of oils. The richness of a species tells about the extent of biodiversity of a site and provides a means for comparing different sites. Category Enlisted species Highly endangered Species. (13) The over exploitation of useful products of wild life should be prevented. (a. Class 8. 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. • Seeds of different genetic strains of commercially important plants can be kept for … Also Read: Vegetative Propagation. Biodiversity can be conserved by In Situ and Ex Situ conservation. Cloudflare Ray ID: 612990e99c550662 Generally, they are more expensive to maintain and should be regarded as complementary to in situ conservation methods.

This be easily understood by observing detrimental effects of global warming and acid rain which cause an unfavorable alteration in logical processes. It describes diversity of habitat over a total land escape or geographical area. The process of protecting biodiversity at all levels by conserving and protecting the whole ecosystem is called in situ conservation. Ex-situ methods focus on species conservation in botanic gardens, zoos, gene banks, and captive breeding programs. Continue . (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. Also in ex- situ conservation, all of which house whole, protected specimens for breeding and reintroduction into the wild when necessary and possible. (15) Efforts should be made for setting up of National parks and wild life sanctuaries to safeguard the genetic diversity and their continuing evolution. 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. The activities like grazing forestry, cultivation and habitat manipulation are not permitted in these areas.

It describes the assemblage and Interaction of spices living together and the physical environment a given area. The in-situ concept is best understood in contrast to ex-situ conservation. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Such type of diversity can generate more productive and stable ecosystems or communities capable of tolerating various types of stresses e.g. compel the human beings to preserve them. Biodiversity has great economic value because economic development depends upon efficient and economic management of biotic resources. Ex situ conservation is the conservation of selected rare plants or animals in places outside the natural forms. 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 … The product species richness and species evenness give species diversity of a region. Thus, it is rightly told, survival of the man depends upon the survival of the biosphere. Classes. (9) Efforts should be made to reduce the level of pollutants in the environment. 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. 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. (ix) There are a number of hot spots (namely Eastern Ghats, Western Ghats, North Eastern hills etc.). Some important national Parks of India are: (i) Biological Park, Nandankanan, Orissa, (ii) Corbett national Park Nainital, U.P. In addition, the habitat fragmentation also brings about microclimatic changes in light, temperature, wind etc. Since earth is homeland of all living organisms, all have equal right to coexist on the surface of earth with all benefits. For example, the landscapes like grass lands, deserts, mountains etc. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g.

Ex situ conservation methods for vegetatively propagated woody species traditionally relied on field or glasshouse collections. There are 37,000 protected areas throughout the world. through the process of hybridization. (c) This technique involves only few species. (12) The habitats of migratory birds should be protected by bilateral and multilateral agreement. Unless some legal value is attached to biodiversity, it will not be possible to protect the rapid extinction of species. (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). Ex-situ (‘off site’) conservation techniques are implemented away from the conservation target's natural habitat. 3. Some of the examples of ex-situ conversation are gene banks, germplasm banks, seed banks. (i) Long-term captive breeding and propagation for the species which have lost their habitats permanently. Mainly the conservation of biodiversity has three basic objectives: (a) To maintain essential ecological processes and life supporting systems. we save the entire forest to save the tiger. (a) The favourable conditions may not be maintained always. (vii) There is wide variety of domestic animals like cows, buffaloes, goats, sheep, pigs, horses etc. Ex-situ conservation: This method refers to the conservation of biodiversity in the areas outside their natural habitat such as zoos and botanical gardens. The shifting or Jhum cultivation by poor tribal people greatly affects the forest structure which is a store house of biodiversity. It also tells about the diversity within the ecosystem. Class 6. 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. There are about 89 national parks in India. Ex-situ Conservation is one of the primary objectives of Botanical Survey of India (BSI).

Another way to prevent getting this page in the future is to use Privacy Pass. These are the small reserves meant for the protection of wild life and their natural habitats. 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 may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. These are maintained by government. 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 only disadvantage of in situ conservation is that it requires large space of earth which is often difficult because of growing demand for space. Botanical gardens, and zoosare the most conventional methods of Ex-situ conservation. Your IP: 185.2.5.12 The magnitude of variation in genes of a species increases with increase in size and environmental parameters of the habitat. In-situ and Ex-situ Conservation Methods. In recent years ex situ conservation has advanced beyond keeping threatened species. 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. 5.1. In Situ Conservation Methods. What is Ex-situ Conservation? In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. living in a wide range of ecosystems. (iii) It has 50,000 known species of insects which include 13,000 butterflies and moths. 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. 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. 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. 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.
