Ex-situ techniques include: seed storage, captive … World crop distribution and centers 3. Ex situ conservation provides less mobility to the organisms due to relatively smaller habitat or area than the in situ. (i) Biodiversity hot spots are regions with high levels of species richness and high degree of endemism (that is species confined to that region are not found anywhere else). : It is onsite conservation or the conservation of genetic resources in natural populations of plant or animal species. Ex situ management is an appropriate component in the conservation of a species if, on balance, stakeholders can be confident that the expected positive impact on the conservation of that species will outweigh the potential risks or any negative impact (which could be to the local population, species, habitat, or ecosystem), and that its use will be a wise application of the available resources. 5) Mobility of in situ and ex situ conservation. In this approach, threatened animals and plants are taken out from their natural habitat and placed in special setting where they can be protected and given special care. 5. This is a crucial conservation method for endangered species. This approach is called in in-situ (on site) conservation. <> In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of Teagan species. It supplements the ex situ conservation efforts of local, national, and international collections and provides some important advantages. we save the entire forest to save the tiger. CWR constitute a valuable genetic resource for crop improvement and the adaptation of agriculture to climate change, estimated by one study, to have provided traits to global agriculture worth $115 billion in one year, 1997, alone. The interests of the indigenous people are also protected. Concept of genetic diversity and conservation 4. In-situ and Ex-situ conservation are the two strategies practised for the preservation of a variety of living species globally. mays ), using 22 simple sequence repeat (SSR) loci. This is the first step to linking ex situ conservation to in situ conservation using community seedbanks as a medium. Insitu conservation involves protection of species in their natural habitat. Ex situ conservation (off-site conservation). In-situ Conservation Ex-situ Conservation; It means onsite conservation. In-situ Conservation In this species are protected in their natural habitat by making their habitats protected areas for example-National parks, Sanctuaries, Biosphere reserves, etc. 1 0 obj 53113 Bonn, Germany, Ex situ conservation – literally: conservation ‘out of place’ – is an important complement to its sister, in situ conservation, meaning conservation ‘in place.’. Zoological parks, botanical gardens, wildlife safari parks and seed banks serve this purpose. 3. Ex situ conservation ( offsite conservation ) This is the off site conservation of animals and plants outside their natural habitats. Especially now that humans have destroyed the natural habitat of most species, ex situ conservation may be the only prudent way forward. Ex situ conservation approaches are typically centered around the collecting, storage and distribution of genetic resources from genebanks, whereas in situ approaches focus on conservation in farmer’s fields or in the wild. It is the conservation of wild species in their natural habitats in order to maintain and recover endangered species. Ex-situ (‘off site’) conservation techniques are implemented away from the conservation target's natural habitat. We all need to conserve biodiversity, as it leads to the conservation of essential ecological diversity to preserve the continuity of food chains. endobj Ex situ Conservation. Ex situ conservation. Genetic variation is maintained away from its original location. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 9 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Many CWR species and populations are at risk, necessitating a systematic global effort to conserve and secure these valuable genetic resources, both in genebanks and in the wild. These techniques are generally appropriate for the conservation of crops, crop relatives and wild species. It is one of two basic conservation strategies, alongside in-situ conservation. Platz Der Vereinten Nationen 7 It is conservation of species in the man-made habitats that imitate the … There is also a need to prioritize ecosystems, species and populations for conservation … The conservation of biodiversity is achieved by two approaches – in situ and ex situ. The importance of in-situ conservation 2. %���� 4. Ex-situ means offsite conservation. Both in situ and ex situ conservation are important strategies for protecting threatened plant species. Biodiversity Conservation. The overall goal of conservation is to mitigate the loss of biodiversity and preserve ecosystem services, species, and genetic diversity for the future. In-situ and ex-situ conservation are two modes of species conservation. This Project has led to the development of a number of tools and resources for people interested in collecting, conserving and using crop wild relatives in breeding. In-situ conservation Ex-situ conservation In this type the conservation is done in the natural environment itself. 2 0 obj In-situ conservation 1.

In situ conservation offers greater mobility to the animal species being safeguarded in its habitat. The project Adapting Agriculture to Climate Change: “Collecting, Protecting and Preparing Crop Wild Relatives” aims to collect important species of crop wild relatives, ensure their long-term conservation, and facilitate their use in breeding new, improved crops. In situ conservation 1. The complementary conservation of CWR both. <> Biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence. In situ and Ex situ Conservation Examples Published: January 11, 2016 In situ conservation means the conservation of ecosystems and natural habitats and the maintenance and recovery of viable populations of species in their natural surroundings and, in the case of domesticated or cultivated species, in the surroundings where they have developed their distinctive properties. Sukriti Singh A0523113081 BTBM/13/242 2. Our Crop Wild Relatives Project has a focus on ex situ conservation: however, this is not to say that we don’t value the importance of complementary in situ conservation approaches, which have the clear advantage of not only preserving genetic diversity per se but also the dynamic evolutionary processes that continue to change and create new genetic diversity. Its primary focus is upon maintaining the health of the natural world, its fisheries, habitats, and biological diversity. Ex-Situ Conservation: Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. %PDF-1.5 When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. While the identification of ex-situ initiatives leaves little room for ambiguity (e.g. Both methods are utmost important and equally adopted in species conservation. Natural park, Sanctuaries Zoos and botanical gardens Government of India has set up a Central Zoo Authority to secure better management of zoos. ex-situ and in-situ conservation of wildlife with reference to zoo gardens and sundarban tiger reserve in west bengal dr. kanailal ghosh conservator of forests CR-55 Fiabilité et compacité - scanged.co La conservation ex situ peut également se dérouler dans les jardins botaniques. In the same way that the wolf is related to the dog, CWR are related to our food plants. In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. endobj The zoological parks are centres of education and recreation, they also play an important role in the conservation of species such as Manipur Thamin deer and the white winged woo… 4 0 obj The conservation of biodiversity is achieved by two approaches – in situ and ex situ. Some of these institutions also play a central role in public education and awareness raising by bringing members of the public into contact with plants and animals they may not normally come in contact with. Both ex situ and in situ conservation approaches should be deployed to ensure CWR availability for use. It is less expensive and easy to manage. Conservation of agricultural genetic resources, whether in situ (in farmers' fields) or ex situ (in a germplasm repository), provides variation for breeding and selection efforts. Therefore, both in situ ecosystem management and in situ conservation play important roles for the conservation of certain plant species in their native habitats. Several of the Project’s outputs, such as the global gap analysis, the occurrence database and the Harlan and de Wet inventory, could play important roles in in situ conservation planning. For example, Xishuangbanna Tropical Botanical Garden plays a leading conservation role because of more native species distributed in that area ( Chen et al., 2009 ). 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. Zoological parks are areas which provide animals with conditions as close as possible to the natural habitats. In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively. Ex situ conservation – literally: conservation ‘out of place’ – is an important complement to its sister, in situ conservation, meaning conservation ‘in place.’. <>>> In situ conservation, on the other hand, requires conservation efforts to be focused on protecting species in their natural ecosystem. Ex situ conservation approaches are typically centered around the collecting, storage and distribution of genetic resources from genebanks, whereas in situ approaches focus on conservation in farmer’s fields or in the wild. THE IMPORTANCE OF IN SITU CONSERVATION. (Maxted et al., 1997) 15 Ex situ techniques . stream Ex situ conservation is a conservation method where the plant or animal species is conserved outside of their natural habitat. This process protects the inhabitants and ensures the sustainability of … 3 0 obj National Parks: Part of land which is controlled by the government and reserved for well being of wildlife, cultivation, grazing, forestry and habitat manipulation are not allowed. Crop wild relatives (CWR) are wild plant species that are related to crops. 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… Conservation is an ethic of resource use, allocation, and protection. In order to ensure the maintenance of biodiversity, there is a need to employ complementary in situ and ex situ conservation. zoos, seed banks, captive breeding), the notion of in-situ conservation covers a broad spectrum of situations ranging from the establishment of a protected area to the design of a sustainable management strategy for a … It means offsite conservation. In this type the organism are conserved in man-made set-up outside their natural habitat. In situ conservation is an important component of the conservation and management of genetic resources. Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. In-situ conservation: Ex-situ conservation In-situ means being in the original position; not having been moved. Ex-situ (‘off site’) conservation is a set of conservation techniques involving the transfer of a target species away from its native habitat. Having copies at the national level adds an extra layer of protection against the loss of these important genetic resources in case of gaps in management, change in preferences and use by the local community and so on. The natural world is losing biodiversity due to the burgeoning human population that is perpetuating the unsustainable use of natural resources (Wilson, 2016). Crop wild relatives are the wild ‘cousins’ of our cultivated crops. ��y�HoݓR�ѱ�{k1��U��q�7-��Q#zz(BG8�� )S۳��ǜoĀ�"�M���cJ�@Hi*�p�U�}�t��s��1#GD��x�p�,�2K�"|E�& 3�o��PZ!VًЂK���§�ގ�uN�\$3���ao1)�?4D�5 ��@{�b�El!�Ӆoa�I6�?pC���0��P��. This article outlines why conservation is needed, the major threats to species, and how diversity is maintained at the ecosystem, species, and genetic levels. Ex situ techniques . In situ conservation. There are 275 zoos, deer parks, safari parks, aquaria etc. Today, we are releasing a policy brief on the importance of both of these two conservation approaches for crop wild relatives, and we encourage all our readers to share it widely and make sure it reaches relevant policy-makers and those who work to raise awareness of these issues. In this study, we assayed levels of genetic diversity from in situ and ex situ populations of Jala, a very tall, large‐eared race of maize ( Zea mays L. subsp.
