Ex situ conservation involves conservation activities especially of endangered species outside their natural habitat. It is done through establishment of zoos, botanical gardens, genetic resource centres and cultural collection. In situ conservation is the conservation of species in their natural habitat. In situ conservation maintains not only the genetic diversity of species, but also the evolutionary adaptations that enable them to adapt continually to shifting environmental conditions. In situ conservation measures involve designating specific areas as protected sites. This is done through establishment of protected areas such as national parks, bird sanctuaries, biosphere reserves, natural reserves, reserves and protected forests and cultural landscapes etc. Although, India is a home to more than 89,000 species of animals and 47,000 species of plants, 1,300 plant species are endangered and 20 species are extinct and many more animal species are...
