Arrange the following IUCN categories in the order of increasing risk ...
Understanding IUCN Categories
The International Union for Conservation of Nature (IUCN) categorizes species based on their risk of extinction. The categories reflect the conservation status, enabling prioritization for conservation efforts.
Categories Explained
- Near Threatened (NT):
- Species that are close to qualifying for a threatened category in the near future.
- Relatively stable but at risk of becoming endangered.
- Vulnerable (VU):
- Species facing a high risk of extinction in the wild.
- Population decline or habitat loss may be evident.
- Endangered (EN):
- Species that are at very high risk of extinction in the wild.
- Significant population reduction or severe habitat fragmentation.
- Critically Endangered (CR):
- Species that are facing an extremely high risk of extinction in the wild.
- Often with very small populations or severe threats.
Order of Increasing Risk
The correct order from least to most risk of extinction is:
3) Near Threatened (NT)
1) Vulnerable (VU)
2) Endangered (EN)
4) Critically Endangered (CR)
This order makes sense because:
- NT species are under less immediate threat compared to VU.
- VU species have higher risk but are not as precarious as EN species.
- EN species are more critical and face greater risks than CR species, which are on the brink of extinction.
Conclusion
Thus, the answer is option 'A' (3, 1, 2, 4), reflecting the increasing risk of extinction from least to most. Understanding these categories is essential for effective conservation strategies.
