Principles of in situ and ex situ conservation of biodiversity In situ conservation is the on-site conservation of genetic resources in natural populations of plants or animal species such as forest genetic resources, in natural populations of tree and animal species. In situ is Latin for “on site”, in situ conservation is therefore the conservation of species diversity within normal and natural habitats and ecosystems. I can't seem to find many specific examples where in situ or ex situ has been used to conserve a species. It aims to enable biodiversity to maintain itself within the context of the ecosystem. And even with only few founding individuals, successful breeding and restitution can take place. It is the methods of conserving all the living species in the artful habitats that reflect their natural living habitats. Ex Situ conservation means conservation outside the habitats by perpetuating sample population in genetic resource centres, for example, zoos, botanical gardens etc. Situ is a Latin word, meaning site. Established botanical and zoological gardens, conservation stands; banks of germplasm, pollen, seed, seedling, tissue culture, gene, and DNA, etc. In other words, it is a set of conservation techniques involving the designation, management, and monitoring of biodiversity in the same area where it is encountered.
