1.Site of one or more globally threatened bird species.
2.Site of biome-restricted species.
3.Have exceptionally large numbers of migratory or congregatory birds.
Choose the correct answer from below given codes:

[A] 1 only

[B] 1 and 2 only

[C] 2 and 3 only

[D] 1, 2 and 3

Answer: D

Explanation: Birds are excellent indicators of ecosystem health. The IBA programme of Birdlife International aims to identify, monitor and protect a global network of IBAs for conservation of the world’s birds and associated biodiversity.

The IBAs serve as conservation areas for protection of birds at the global, regional or sub-regional level. According to Birdlife International, designation of IBAs is based on standardized criteria, namely

  1. hold significant numbers of one or more globally threatened bird species,
  2. be one of a set of sites that together hold a suite of restricted-range species or biome-restricted species and
  3. have exceptionally large numbers of migratory or congregatory birds.

The IBAs contain a range of habitats, such as wetlands, mudflats, microhabitats in biodiversity hotspots, grasslands and scrublands, making them excellent indicators of biodiversity richness (India’s 5th National Report to the Convention on Biological Diversity, 2014).

  • The Bombay Natural History Society (BNHS; www.bnhs.org) And Birdlife International have identified 467 IBAs in India (Islam and Rahmani, 2004).
  • Forty percent of these IBAs fall outside the PA network and thus form an important tool for landscape-level conservation planning. BNHS has also prepared a list of 96 new/potential sites which can be designated as IBAs in the future.
