Difference between In Situ and Ex Situ Conservation

In situ conservation means conservation which takes place onsite. The major aim of this type of conservation is to preserve natural areas of the organisms and maintain their number. This type of conservation includes designation, managing and supervise the target taxa in the place they are present. This method is beneficial for conservation of wild organisms and for animal breed material on farm.

This method is considered to be more dynamic because it is carried out in the natural habitat itself. In situ conservation is a wonderful method to protect an endangered plan or animal species in its natural area, either by safeguarding the habitat itself, or by protecting the species from the predators.

It helps in agricultural biodiversity conservation farmers who use uncustomary agricultural practices. Ex situ conservation means conservation which takes place off-site. 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.

This method is more static and is quite suitable for conservation of several crops and their wild varieties. Various methods involved include in vitro storage, DNA storage, seed banks, pollen storage etc. Some examples of ex situ conservation include one horned rhinoceros, golden michelia. Botanical parks and Zoos are considered the most convention methods of ex situ conservation Hamilton, Figure 1. In situ and ex situ biodiversity conservation Dullo, It is the conservation and protection of genetic resources of plant and animal species in their natural habitats itself.

It is conservation of biological diversity outside their natural areas and is done through different methods like captive breeding, botanical garden, zoos, aquaria etc. Conservation of species in in situ takes place in their natural habitats. Some of the operations include performance recording, breeding programmes, ecosystem management at sacred groves, gene sanctuary, biodiversity hotspots, community reserves and biosphere reserves.

Ex situ conservation involves plant and animal species. Conservation of plants include; storage of seeds, conservation of pollen, artificial propagation of plants along with reintroduction into the wild, and storing plant shoots in situation of suspended development in vitro conservation. In situ conservation offers greater mobility to the animal species being safeguarded in its habitat. Ex situ conservation provides less mobility to the organisms due to relatively smaller habitat or area than the in situ.

For e. Botanical gardens like Kew In London. Thanks for another informative blog. Where else may just I am getting that kind of info written in such a perfect approach? Your email address will not be published. Notify me of followup comments via e-mail. What is In situ conservation? This type of conservation is divided onto three types: Protected area conservation Home garden conservation On-farm conservation In situ conservation is a wonderful method to protect an endangered plan or animal species in its natural area, either by safeguarding the habitat itself, or by protecting the species from the predators.

It helps in agricultural biodiversity conservation farmers who use uncustomary agricultural practices e. Nilgiri biosphere in India Jackson, Benefits of in situ conservation It helps to recover populations in the habitat where their distinct attributes have developed.

This method ensures not only multiplication of the species, but process of evolution and adaptation as well. It is a cheap and convenient method of conserving biological diversity. What is Ex situ conservation? Techniques for plant include: Tissue cultute storage and propagation Field gene banking Cultivation collections Inter situ Techniques for animals include: Genetic management of captive populations Avoiding adaptations to captivity Minimizing mean kinship Benefits of ex situ conservation Advanced reproduction techniques will maximize the probability of reproductive success for endangered species Due to human intervention, health of organisms can be monitored and medical assisstance is accessible when ever required.

There are more than Botanical parks globally protecting and conserving more than 80, species, around Zoos wiith 3, species of plants, animals, mammals, amphibians and many Gene banks. Organisms are well attended to, provided food, security, medical aid and hence have a greater life -span and reproductive capacity.

A species or a population sample of a particular part of its genetic variation can be maintained through in situ or ex situ conservation. In situ conservation is the preservation of species and populations of living organisms in a natural state in the habitat where they naturally occur. This method preserves both the population and the evolutionary processes that enable the population to adapt by managing organisms in their natural state or within their normal range.

Biodiversity possesses rich and diverse fauna and flora and unique natural beauty in its different ecosystems. The maintenance of species and ecosystems is a keystone to sustainable development. Therefore, the protection and efficient management of wild species and their environment is the prime objective of conservation.

Conservation is the protection, preservation, management, or restoration of wildlife and natural resources such as forests and water. Through the conservation of biodiversity and the survival of many species and habitats which are threatened due to human activities can be ensured. There is an urgent need, not only to manage and conserve the biotic wealth, but also restore the degraded ecosystems. Humans have been directly or indirectly dependent on biodiversity for sustenance to a considerable extent. However, increasing population pressure and developmental activities have led to large scale depletion of the natural resources. In-situ conservation is 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 tree species.

Ex situ conservation literally means, "off-site conservation ". It is the process of protecting an endangered species, variety or breed , of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, example are zoological parks and wildlife safaris. Ex situ management can occur within or outside a species' natural geographic range. Individuals maintained ex situ exist outside an ecological niche. This means that they are not under the same selection pressures as wild populations, and they may undergo artificial selection if maintained ex situ for multiple generations. Agricultural biodiversity is also conserved in ex situ collections. This is primarily in the form of gene banks where samples are stored in order to conserve the genetic resources of major crop plants and their wild relatives.

In-situ and Ex-situ Conservation Methods. In Situ Conservation Methods. In-situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity. Conserving the areas where populations of species exist naturally is an underlying condition for the conservation of biodiversity.
