Ex-situ Conservation — Prelims Strategy
Prelims Strategy
For Prelims, a strong factual foundation is paramount. Begin by clearly understanding the definition of ex-situ conservation and distinguishing it from in-situ conservation.
Memorize the various methods: seed banks, gene banks, botanical gardens, zoological parks, aquariums, cryopreservation, tissue culture, and captive breeding. For each method, know its primary purpose and a key Indian example (e.
g., NBPGR for seed banks, CZA for zoos). Pay attention to specific terms like 'orthodox seeds' vs. 'recalcitrant seeds' and the temperature used in cryopreservation. Understand the roles of key organizations like the Central Zoo Authority and the National Bureau of Plant Genetic Resources.
Familiarize yourself with the relevant provisions of the Wildlife Protection Act, 1972, and the Biological Diversity Act, 2002, as they pertain to ex-situ efforts. Additionally, be aware of international conventions like the CBD and GSPC that support ex-situ conservation.
Practice MCQs that test your ability to identify ex-situ methods, differentiate them from in-situ, and recall specific facts and examples. The 'SPACE-R Framework' mnemonic will be particularly useful for quick recall of methods.
