Introduction to Biodiversity Hotspots
Biodiversity hotspots are regions that are both rich in endemic species and significantly threatened by human activities. The concept was introduced by Norman Myers in 1988.
Statement Analysis
- Statement 1: "Norman Myers introduced the concept of Biodiversity hotspots."
- This statement is correct. Norman Myers is credited with defining the term and establishing criteria for identifying biodiversity hotspots.
- Statement 2: "One of the criteria to qualify as Biodiversity Hotspots is, it must contain at least 15,000 species of endemic vascular plants."
- This statement is also correct. To qualify as a biodiversity hotspot, a region must have at least 1,500 species of vascular plants that are endemic, not 15,000. Thus, this statement is misleading and incorrect.
- Statement 3: "Western Himalayas fall under a biological hotspot."
- This statement is incorrect. While the Himalayas are a biologically rich area, the Western Himalayas specifically do not qualify as a recognized biodiversity hotspot according to Myers’ criteria.
Conclusion
Based on the above analysis, the only correct statement is Statement 1. Therefore, the correct answer is option 'A' (1 only).
