In situ Conservation

Ex situ Conservation

It means the conservation of biodiversity in their natural habitats itself.

It means the conservation of biological diversity outside their natural areas

Protected areas are the sanctuaries and national parks.

Artificial conditions are created to make their habitat almost like a natural habitat.

It aims to enable biodiversity to maintain itself within the context of the ecosystem.

It involves the maintenance of genetic variation (Genetic Conservation) away from its original location.

Establish a protected area network, with appropriate management practices, corridors to link fragments restore degraded habitats within and outside.

Established botanical and zoological gardens, conservation stands; banks of germplasm, pollen, seed, seedling, tissue culture, gene, and DNA, etc.

It involves the reduction of biotic pressure rehabilitation

It identifies and rehabilitates threatened species; launched augmentation, reintroduction, or introduction programs.

It helps in the multiplication of the species through the process of evolution and adaptation.

This method will enhance the probability of reproductive success for endangered species.

It provides greater mobility to the animal species because of the large habitat area.

It provides less mobility to the organism because of the small habitat area.

Example- National parks, biosphere reserves, parks, sanctuaries.

Example- Zoo, aquarium, seed banks, botanical gardens, etc.
