Ex Situ Conservation Methods — NEET Biology
✅ Asked in NEET 2025Ex situ Conservation– In this approach, threatened animals and plants are taken out from their natural habitat and placed in special setting where they can be protected and given special care. Zoological parks, botanical gardens and wildlife safari parks serve this purpose. There are many animals that have become extinct in the wild but continue to be maintained in zoological parks. In recent years ex situ conservation has advanced beyond keeping threatened species in enclosures. Now gametes of threatened species can be preserved in viable and fertile condition for long periods using cryopreservation techniques, eggs can be fertilised in vitro, and plants can be propagated using tissue culture methods. Seeds of different genetic strains of commercially important plants can be kept for long periods in seed banks.
Ex situ conservation means protecting endangered species outside their natural habitat using zoological parks, botanical gardens, and wildlife safari parks. NTA tests whether students can distinguish this from in situ conservation and identify modern techniques like cryopreservation, in vitro fertilization, tissue culture, and seed banking. Students often confuse ex situ with in situ conservation or forget that ex situ includes advanced biotechnology methods beyond just keeping animals in enclosures. Remember: ex situ = artificial settings with special care; it's now more than just zoos—it includes preserving gametes, seeds, and using lab techniques to maintain genetic diversity of threatened species.
