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 conservation ( offsite conservation ) This is the off site conservation of animals and plants outside their natural habitats. 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. endobj
This process protects the inhabitants and ensures the sustainability of … 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. Ex-situ means offsite conservation. In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively. This is the first step to linking ex situ conservation to in situ conservation using community seedbanks as a medium. The importance of in-situ conservation 2. 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. <>
In certain cases, ex situ conservation is the only plausible means of undertaking protection of biodiversity. There are 275 zoos, deer parks, safari parks, aquaria etc. Ex situ techniques . mays ), using 22 simple sequence repeat (SSR) loci. Ex-situ conservation provides excellent research opportunities on the components of biological diversity. Crop wild relatives are the wild ‘cousins’ of our cultivated crops. 4 0 obj
Also read: Biodiversity. For example, Xishuangbanna Tropical Botanical Garden plays a leading conservation role because of more native species distributed in that area ( Chen et al., 2009 ). The main difference between in-situ and ex-situ conservation is that in-situ conservation performs inside the natural habitats while ex-situ conservation performs outside or exterior to the natural habitats. It supplements the ex situ conservation efforts of local, national, and international collections and provides some important advantages. Ex situ conservation – literally: conservation ‘out of place’ – is an important complement to its sister, in situ conservation, meaning conservation ‘in place.’. In this type the organism are conserved in man-made set-up outside their natural habitat. THE IMPORTANCE OF IN SITU CONSERVATION. (Maxted et al., 1997) 15 Ex situ techniques . The conservation of biodiversity is achieved by two approaches – in situ and ex situ. Crop wild relatives (CWRs) are important reservoirs of adaptive traits for crop breeding programmes. Platz Der Vereinten Nationen 7 These techniques are generally appropriate for the conservation of crops, crop relatives and wild species. Biodiversity Conservation. Ex-Situ Conservation: Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. <>
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. <>>>

Especially now that humans have destroyed the natural habitat of most species, ex situ conservation may be the only prudent way forward. In situ conservation is an important component of the conservation and management of genetic resources. Global Crop Diversity Trust Crop wild relatives (CWR) are wild plant species that are related to crops. Its primary focus is upon maintaining the health of the natural world, its fisheries, habitats, and biological diversity. 2 0 obj

In-situ conservation Ex-situ conservation In this type the conservation is done in the natural environment itself. : It is onsite conservation or the conservation of genetic resources in natural populations of plant or animal species. Ex-situ techniques include: seed storage, captive … 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. Conservation is an ethic of resource use, allocation, and protection. In situ conservation 1. 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.’. The natural world is losing biodiversity due to the burgeoning human population that is perpetuating the unsustainable use of natural resources (Wilson, 2016). 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. The complementary conservation of CWR both. This approach is called in in-situ (on site) conservation. In situ conservation. 3. 4. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. Ex situ conservation (off-site conservation). Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. In-situ conservation provides the required green cover and its associated benefits to our environment. In-situ and Ex-situ conservation are the two strategies practised for the preservation of a variety of living species globally. It is the conservation of wild species in their natural habitats in order to maintain and recover endangered species. There is also a need to prioritize ecosystems, species and populations for conservation … Tags : biodiversity, conservation, crop wild relatives, ex situ, in situ, We use cookies to analyze the site usage and to improve our users' experience Continue without cookies Yes, I accept. Government of India has set up a Central Zoo Authority to secure better management of zoos. Concept of genetic diversity and conservation 4. Therefore, both in situ ecosystem management and in situ conservation play important roles for the conservation of certain plant species in their native habitats. In situ conservation, on the other hand, requires conservation efforts to be focused on protecting species in their natural ecosystem. In this changing world, there is an increasing need for a “One Plan Approach” to develop multi-disciplinary conservation strategies tha… 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. 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. 5) Mobility of in situ and ex situ conservation. Both in situ and ex situ conservation are important strategies for protecting threatened plant species. Genetic variation is maintained away from its original location. 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. Zoological parks, botanical gardens, wildlife safari parks and seed banks serve this purpose. In the same way that the wolf is related to the dog, CWR are related to our food plants. 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. 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. The interests of the indigenous people are also protected. While the identification of ex-situ initiatives leaves little room for ambiguity (e.g. Biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence. 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… Sukriti Singh A0523113081 BTBM/13/242 2. In-situ Conservation Ex-situ Conservation; It means onsite conservation. 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. In situ 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. It is one of two basic conservation strategies, alongside in-situ conservation. 1 0 obj
