Q1. With reference to the conservation of the Great Indian Bustard (GIB), consider the following statements:
- Captive breeding can increase the numerical strength of a threatened species, but by itself cannot address habitat fragmentation and mortality caused by infrastructure.
- The conservation of the GIB illustrates the relevance of a landscape-level approach, since its survival is influenced by grasslands, agricultural landscapes and infrastructure occurring outside conventional protected areas.
- Undergrounding all overhead power lines throughout the GIB's range is necessarily the only viable way of reconciling renewable-energy development with GIB conservation.
- A species-specific conservation programme can be considered successful even if the species' population increases while its natural habitat continues to deteriorate.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 1, 2 and 3 only
(c) 3 and 4 only
(d) 1, 2, 3 and 4
Answer: (a)
Explanation:
- Statement 1 is correct: Captive breeding addresses population numbers but does not eliminate threats such as habitat loss, fragmentation and power-line collisions.
- Statement 2 is correct: The GIB occupies a wider grassland–agricultural landscape, making habitat connectivity and management outside protected areas important.
- Statement 3 is incorrect: The article highlights a more nuanced approach in which undergrounding requirements were subsequently restricted to a subset of power lines within critical GIB habitat, reflecting the conservation–development trade-off.
- Statement 4 is incorrect: Numerical recovery without restoration of viable habitat does not necessarily constitute long-term conservation success.
