Difference between In-Situ and Ex-Situ conservation
Conservation of biodiversity and genetic resources helps protect, maintain and recover endangered animal and plant species. There are mainly two strategies for the conservation of wildlife: In-situ conservation and Ex-situ conservation. Although, both the strategies aim to maintain and recover endangered species, they are different from each other. Let us see how they differ from each other!
In-situ conservation, which is also known as "on-site conservation", refers to the conservation of wild species in their natural habitats and environment. It aims to conserve the natural habitats of the living creatures and maintain and recover wild species, especially the endangered species. The national parks, wildlife sanctuaries and biosphere reserve are some of the examples of in-situ conservation. This method of conservation allows animals flourish in their natural habitat and food chain and offers more mobility to the animals. It is suitable for the conservation of animals that are found in abundance.
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. zoo, aquarium, botanical garden etc. It offers less mobility to the animals as it is smaller in area than the area of in-situ conservation. This method of conservation is suitable for the animals which are not found in abundance.
It provides protection to animals against predators, unfavourable climatic conditions and other hostile factors. Furthermore, proper food and care is provided under good supervision.
Based on the above information some of the key differences between in-situ and ex-situ conservation are as follows:
