In-situ conservation refers to the conservation of any species in its natural habitat without transferring them anywhere. It is also known as on-site conservation and the most appropriate method of conservation.

Ex-situ conservation refers to the conservation of any species outside its natural habitat. For example- storung to seeds, sperms, ova in gene banks, zoos, botanical gardens, etc.
