Question 72: Environment and Ecology

Which one of the following is not a site for in-situ method of conservation of flora ?

aBiosphere Reserve
bBotanical Garden
cNational Park
dWildlife Sanctuary

AnswerThe answer is (b).

In-situ conservation protects species in their natural habitat: national parks, wildlife sanctuaries, biosphere reserves and other protected areas. Ex-situ conservation keeps species outside their natural habitat, as in botanical gardens, zoos, gene banks and seed banks. A botanical garden is therefore not an in-situ site.

Why each option is right or wrong
  • (a) An in-situ site: biosphere reserves protect species in their habitat.
  • (b) Right: a botanical garden is an ex-situ method.
  • (c) An in-situ site: national parks protect species in the wild.
  • (d) An in-situ site: sanctuaries protect species in their habitat.
