1. Conservation of species & habitat
2. Natural Evolution of Species
3. Sustainable method of conservation
Plant and animal genetic resources are conserved on-site or in natural ecosystems,It has the major advantage of conserving the entire ecosystem, rather than a particular species.
Natural habitats allow animals to evolve naturally and are more sensitive to natural threats. They are also able to adapt easily to phenological changes as well as live alongside predators.
Release sites are carefully chosen to maximize the chances of survival, where there is plenty of food, water, and suitable nesting sites.
Conservation in situ is considered to be more sustainable since a higher species diversity ensures natural sustainability for all life forms.
