The conservation of biodiversity is achieved by two approaches – in situ and ex situ. Which one of the following is not a site for in-situ method of conservation of flora? Such ex situ work is an increasingly important component of conservation and restoration efforts. It is one of two basic conservation strategies, alongside in-situ conservation. The authors showed that of 68 vertebrate species with improved conservation status as per t… Ex situ conservation is a conservation method where the plant or animal species is conserved outside of their natural habitat. Ex-situ Conservation of Biodiversity comprises of aquariums, botanical gardens, Cryopreservation, DNA banks, zoos, etc. Furthermore, in situ methods are less expensive and less manageable while the ex situ methods are expensive and manageable. )Biosphere Reserve (b.) 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. It is located in Cuc Phuong National Park, the area just mentioned also in Ninh Binh, so in the North of Vietnam, right outside of Hanoi. Ex-situ conservation strategies: Such strategies include establishment of botanical gardens, zoos, conservation strands and gene, pollen seed, seedling, tissue culture and DNA banks. This worked well with my chatty year 12's. You need highlighters and I use timers however I … Now, both of these definitely are very vital to the preservation and conservation of species and depending on how things are going within a particular area, that'll help to dictate what is going to be the most practical measure, most practical course for them. Units of ex situ conservation include zoological parks, botanical gardens, and seed banks. Biodiversity encompasses variety and variability of all forms of life on earth that play a great role in human existence. 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. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Geese make resources of grasses and seeds; these plants make resources of sunlight and water. Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. In the last little video, the last slide there was talking about in situ and ex situ conservation practices. Construction Engineering and Management Certificate, Machine Learning for Analytics Certificate, Innovation Management & Entrepreneurship Certificate, Sustainabaility and Development Certificate, Spatial Data Analysis and Visualization Certificate, Master's of Innovation & Entrepreneurship. Ex-Situ Conservation: Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Establishes protected area networks. In order to respond to the amphibian extinction global crisis, many initiatives to rescue endangered frogs and conserve biodiversity have been born. The main objective of ex situ techniques is to support conservation by ensuring the survival of threatened species … Especially now that humans have destroyed the natural habitat of most species, ex situ conservation may be the only prudent way forward. Ex-situ means offsite conservation. Seed gene bank: This is easiest way to store the germ plasma of plants at low temperature. Ex situ conservation means conservation which takes place off-site. Again, to bring zoos up is an example of this, they will have a center called studbooks. Conservation Methods 4.1 Ex Situ versus In Situ Methods. We will learn about 'in situ' and 'ex situ' conservation methodology. Although viable populations of some organisms can be maintained ex-situ either under cultivation or in captivity, these methods are far less effective than in-situ methods, and, generally, they are extremely costly. The species that is going to be conserved is the Delacour's langur. Seed gene bank: This is easiest way to store the germ plasma of plants at low temperature. Both ex situ and in situ conservation approaches should be deployed to ensure CWR availability for use. Ex-situ means offsite conservation. 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… They move animals from zoos to zoos in order to help spread genetic diversity. 3.7 3 customer reviews. Obviously, if you're trying to put an animal back into the wild, the first thing that has to happen is you have to have a good habitat for them. Start studying Biology- conservation in situ and ex situ. zoo, aquarium, botanical garden etc. When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected.E.g. For ex situ conservation, we can have the establishment of botanical and zoological gardens and conservation stands. Ex Situ conservation means conservation outside the habitats by perpetuating sample population in genetic resource centres, for example, zoos, botanical gardens etc. This involves conservation of genetic resources, as well as wild and cultivated or species, and draws on a diverse body of techniques and facilities. 1997b). 3. Germplasm Conservation The Germplasm has to be maintained in such a state that there is minimum risk for its loss and that either it can be planted directly in the field or it can be prepared for planted for planting with relative ease. Ex-situ techniques include: seed storage, … In-situ conservation of Biodiversity includes biosphere reserves, national parks, wildlife sanctuaries, etc. This process protects the inhabitants and ensures the sustainability of … Ex-situ conservation, also known as off-site conservation is the conservation mode in which species conservation takes place outside of their natural habitats. 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 . We are presently facing a potential extinction crisis for the order Primates (and many other life forms). To that end, there always is this discussion of creativity and flexibility within that. In-situ conservation: Ex-situ conservation In-situ means being in the original position; not having been moved. If ex situ conservation is to play an effective role in conserving wild plant diversity and supporting habitat conservation, appropriate levels of infrastructure and capacity need to be established (Maunder et al. Ex situ coconut conservation is facing a crisis. 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. 4.3 Conservation Organizations and What You Can Do! Aims to enable biodiversity to maintain itself within the context of the ecosystem. To view this video please enable JavaScript, and consider upgrading to a web browser that In order to ensure the maintenance of biodiversity, there is a need to employ complementary in situ and ex situ conservation. This approach is called in in-situ (on site) conservation. There are two Methods of biodiversity conservation. (a. Ex-situ methods focus on species conservation in botanic gardens, zoos, gene banks, and captive breeding programs. Finally, we will look at a number of conservation organizations and think about ways that the public can get involved. Really what this is asking is, where do you try to protect the animal? There is also a need to prioritize ecosystems, species and populations for conservation … Essentially areas that have a far greater biodiversity value and ecological value, but are not necessarily natural in and of themselves. For in situ, you're really looking to main ecological integrity. In-situ conservation is one of two basic conservation strategies, alongside 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. Ex-situ conservation Ex situ or ‘off-site’ conservation means the conservation of components of biological diversity outside their natural habitats. 1. 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. This module will address conservation organizations in multiple contexts. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. What are ways that we can possibly help in order to conserve a number of these species? 3. What is Ex-situ Conservation? Because of this fundamental difference, there is little overlap between the two strategies. Where do you try to protect the biodiversity? Ex situ it's going to be artificial conditions are created to make their habitat almost like a natural habitat. This in-situ/ex-situ integration necessitates collaboration at all levels of conservation action including planning, implementation, monitoring and finally assessment to drive adaptive management processes. In-situ methods use conservation areas as "warehouses" of biological information. Author: Created by abuckland87. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. There is an obvious fundamental difference between these two strategies: ex situ conservation involves the sampling, transfer, and storage of target taxa from the target area, whereas in situ conservation involves the designation, management, and monitoring of target taxa where they are encountered. A protected area is a geographically defined area that is designated or regulated and managed to achieve specific conservation objectives. We will investigate conservation status, threats to conservations, success and failures within protecting our closest evolutionary cousins. Roughly one out of seven known threatened species on the planet can be found in a zoo or an aquarium (Conde et al., 2011) and captive breeding in such institutions may be the only practical conservation option left for some species whose habitats are dwindling. zoo, aquarium, botanical garden etc. 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. You've got ranger patrols, you've got conservation organizations that have come in and well, we can use this species, we can talk about both in situ and then we can also talk about ex situ conservation. It […] 2) It only lives in Vietnam and is restricted to a very small area, just this Van Long Nature Reserve. Finally, we will look at a number of conservation organizations and think about ways that the public can get involved. We will learn about 'in situ' and 'ex situ' conservation methodology. The population recovers in natural environment. 4. Article 8 of the Convention on Biological Diversity (CBD) specifies in-situ conservation as the primary conservation strategy, and states that ex-situ measures should play a supportive role to reach conservation targets. Such strategies include Protected areas --- national game parks , wild life sanctuaries , Biosphere reserves , Ramsar sites & world heritage centers. when conservation occurs within the natural habitat/environment of the plant or animal, plants and animals conserved in their natural habitat, endangered habitats may be fragmented, each small area may not be large enough to ensure survival, conservation which occurs outside the normal habitat and environment of the species, organisms are protected from predation and poaching, captive population is always likely to have a limited genetic diversity, where does ex situ conservation of plants occur, reasons why ex situ of plants may be easier than ex situ of animals (botanic gardens), seeds can be stored and germinated in protected surroundings, some difficulties of ex situ conservation with plants (botanic gardens), funding a botanic garden can be difficult as public perception of plants isn't the same as animals so fewer people are willing to donate or sponsor, seed banks contain seeds that can remain viable for decades and possibly hundreds of years, very dry or freezing conditions to make sure the seed remains viable. Ex situ conservation is a conservation method where the plant or animal species is conserved outside of their natural habitat. Zoos and aquariums, as conservation organizations, have long been involved in partnerships to work toward biodiversity conservation (Field and Dickie, 2007). In-situ conservation: Ex-situ conservation In-situ means being in the original position; not having been moved. January 2018; DOI: 10.1016/B978-0-12-804088-1.00023-X. Zoological parks, botanical gardens, wildlife safari parks and seed banks serve this purpose. Both in situ and ex situ methods of biodiversity conservation are equally important. In-situ and ex-situ conservation are two modes of species conservation. back at top . For ex situ conservation, we can have the establishment of botanical and zoological gardens and conservation stands. 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. In-situ conservation of biodiversity and protected areas. This rescue center works, again with Delacour langurs and what's nice is that well, they've been very successful in having a breeding program for this species and have worked to try to translocate, so take these animals that have been taken from illegal animal trade and rescued, put them into the center, rehabilitate them and they have animals both in these cages, so these more naturalistic enclosures.
