India’s Species Threat Abatement and Restoration (STAR) score.


According to a new study, Kerala, Tamil Nadu and Karnataka host a large share of India’s threatened and endemic species of amphibians, birds and mammals.


Key findings of the study:

  • The three states (Kerala, Tamil Nadu and Karnataka) account for 51 per cent of the country’s species threat abatement and restoration (STAR) score.

Species threat abatement and restoration (STAR) score.

  • The score is a measure of the contribution that investments can make to reduce species extinction risk.
  • A higher STAR score indicates greater presence of threatened species. 
  • It can help national and subnational governments, cities and other entities target their investments and activities to achieve conservation outcomes.

  • India’s total score: India’s total national STAR score was 41,817, of which 11,585 was for mammals, 10,843 for birds and 19,389 for amphibians.
  • Global score: The global STAR score for the three species groups combined was 1,223,500.
  • India's national STAR score represented
  • 4 per cent of the global STAR
  • 7 per cent for mammals
  • 9 per cent for birds
  • 6 per cent for amphibians
  • The top 20 per cent of all 36 states contributed 80 per cent to the national STAR score.
  • These include Kerala (20 per cent)
  • Tamil Nadu (18 per cent)
  • Karnataka (13 per cent)
  • Arunachal Pradesh (6 per cent)
  • Assam (5 per cent)
  • Maharashtra (5 per cent)
  • Andaman and Nicobar Islands in the Indian Ocean (12 per cent)
  • Lowest scoring: In contrast, the 20 states with lower STAR scores contributed only 6 per cent to the national STAR score.
    • This is because several of them are small in area and host few threatened species. 
    • Several bigger states such as Uttar Pradesh, Bihar, Odisha and Telangana, however, contributed less than 1 per cent to the national STAR score

What are the threats?

  • Annual and perennial non-timber crop production.
    • Such threats alone account for 44 per cent of the total Indian STAR score.
  • The next important threats are biological resource use
    • hunting and collecting birds and animals, logging and wood harvesting
    • residential and commercial development
