Depending upon the immediate urgency of the need to conserve biodiversity, arrange the options given below in a descending order.
(A) Hot spots
(B) Sacred groves
(C) Ex situ method
(D) Bioreserves
Choose the most appropriate answer from the options given below.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (C), (B), (D), (A)
Ex situ methods (C)
- These are considered most urgent because they are the last resort. If a species is on the verge of extinction (e.g., Cheetah, endangered plants), we can’t wait for hotspot/biosphere protection. So urgent action is gene banking, cryopreservation, botanical gardens, zoos → placed first.
Sacred groves (B)
- Traditional community-protected patches of forest.They conserve rare species effectively at small scale. Immediate protection exists, so next in urgency.
Bioreserves (D)
- Large government-protected areas. Threat is less immediate because legal protection is already there.
Hotspots (A)
- Although biologically richest and highly threatened, many textbooks and exam keys consider them long-term conservation goals rather than "immediate urgency," since they cover vast regions needing global coordination (not short-term emergency action).
That’s why the given correct answer is Option 4 (C, B, D, A).
