Q. With reference to the IUCN classification of conservation priority, consider the following pairs:
IUCN CategoryKey Criteria
1.Near Threatened (NT) – Does not qualify for threatened categories now, but likely to in near future.
2.Vulnerable (VU) – Reduction in population > 50% over the last 10 years or < 10,000 mature individuals.
3.Least Concern (LC) – Widespread and abundant taxa.
4.Extinct in the Wild (EW) – Survives only in cultivation, captivity, or naturalized populations outside past range.
How many of the above pairs are correctly matched?

[A] Only one

[B] Only two

[C] Only three

[D] All four

Answer: D
Notes:

Explanation:

  • NT is evaluated against criteria but does not yet qualify for threatened categories; close to qualifying in near future.
  • VU criteria include >50% population reduction in last 10 years OR <10,000 mature individuals.
  • LC covers widespread and abundant species that do not fit threatened categories.
  • EW species survive only in cultivation, captivity, or as naturalized populations outside their historical range.
