Question

Difficulty: EasyBiodiversity Conservation Strategies: In-situ and Ex-situ

Match each biodiversity conservation strategy or site in List-I with its correct conservation classification and defining feature in List-II.

  • Biosphere ReserveIn-situ conservation of whole ecosystems, including indigenous human communities, partitioned into core, buffer, and transition zones.
  • Botanical GardenEx-situ conservation involving off-site cultivation, scientific study, and public exhibition of living plant collections.
  • CryopreservationEx-situ preservation of genetic material such as seeds and gametes at ultra-low temperatures using liquid nitrogen.
  • Sacred GroveIn-situ protection of forest patches and wildlife conserved on-site through traditional cultural beliefs and community veneration.

Answer

Biosphere Reserve matches with in-situ ecosystem conservation divided into core, buffer, and transition zones; Botanical Garden matches with ex-situ cultivation and display of live plants; Cryopreservation matches with ex-situ ultra-low temperature storage of genetic material; Sacred Grove matches with in-situ community protection of natural forest patches through cultural traditions.
In-situ conservation protects wild species within their natural habitats and ecosystems (e.g., Biosphere Reserves with core-buffer-transition zones, and Sacred Groves preserved by indigenous communities). Ex-situ conservation safeguards organisms outside their natural environments using specialized facilities or technology (e.g., Botanical Gardens displaying cultivated plants, and Cryopreservation preserving genetic stock at ultra-low temperatures).

Step-by-Step Solution

1
Classify Biosphere Reserve based on location and scope.
Biosphere Reserves protect species in their natural habitats (in-situ) along with local communities across structured zones.
On-site habitat preservation defines in-situ strategy.
2
Classify Botanical Garden based on location and function.
Botanical Gardens grow plants outside their natural habitats for research and education (ex-situ).
Off-site management of living species is an ex-situ conservation method.
3
Classify Cryopreservation techniques.
Cryopreservation stores biological samples in liquid nitrogen in laboratory conditions (ex-situ).
Preserving genetic samples under controlled artificial conditions is an ex-situ strategy.
4
Classify Sacred Groves based on protection mechanism.
Sacred Groves maintain pristine forest patches in their original natural locations (in-situ).
Community-led protection of wild natural habitats constitutes in-situ conservation.

Key Concept

Classification of Biodiversity Conservation into In-situ (on-site natural habitat protection) and Ex-situ (off-site artificial facility preservation).
