Genetic diversity plays a very important role in survival and adaptability of a species because when a species’ environment changes, slight gene variations are necessary for it to adapt and survive.

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
