The “Red Data Books” published by the International Union for Conservation of Nature and Natural Resources (IUCN) contain lists of 1. Endemic plant and animal species present in the biodiversity hotspots. 2. Threatened plant and animal species. 3. Protected sites for conservation of nature and natural resources in various countries. Select the correct answer using the codes given below:
- A1 and 3
- B2 onlyCorrect
- C2 and 3
- D3 only
Explanation
The correct answer is B because the primary purpose of the IUCN Red Data Books is to identify and document species that are at risk of extinction.
Statement 1 is incorrect because the Red Data Book focuses on the global conservation status of species based on their risk of extinction, not specifically on whether they are endemic to biodiversity hotspots.
Statement 2 is correct as the Red Data Book categorizes species into specific groups such as Critically Endangered, Endangered, and Vulnerable, which collectively represent threatened species.
Statement 3 is incorrect because the Red Data Book lists species, not protected sites. Information regarding protected areas and conservation sites is typically managed by other databases, such as the World Database on Protected Areas.
Therefore, only statement 2 is accurate.
