Alien species in India

June 24 , 2025 12 hrs 0 min 18 0
  • A 2022 study found that India has lost $127.3 billion (Rs 830 crore) to invasive alien species over the last 60 years.
  • It was rendering the country the second-most financially affected by an invasive alien species in the world, after the U.S.
  • But this data only stems from the calculated costs of 10 invasive alien species from the 2,000+ alien species known in India.
  • The most conservative estimates report 173 invasive plants and 157 invasive animals.
  • In India, the declaration of alien species as invasive is managed under the Wildlife Protection Act, 1972 (amended in 2022).
