Explanation

In situ (on-site) conservation is the conservation and protection of the whole ecosystem and its biodiversity at all levels, in order to protect the threatened species. Two in situ methods are being used to save biodiversity viz., hotspots and protected areas. Protected areas include national parks, sanctuaries, biosphere reserves, and sacred groves. Ex situ (off-site) conservation is the conservation of selected rare plants/animals in places outside their natural homes. Ex-situ conservation includes offsite collections, seed banks, gene banks, in vitro fertilization, cryopreservation techniques, and tissue culture.
