Which of the following is not an example of in-situ biodiversity conservation?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Botanical Garden
A botanical garden keeps plants away from their natural habitat, so it is a classic ex-situ method along with zoos, seed banks, gene banks and tissue-culture repositories.
Wildlife sanctuaries, national parks and biosphere reserves all protect species where they naturally occur, together with their habitat, and are therefore in-situ conservation.
