White-bellied Heron Habitat Threat

July 28 , 2026 9 hrs 0 min 11 0
  • A proposed 1,200 megawatt (MW) hydroelectric project on the Lohit River, Arunachal Pradesh, threatens the habitat of the Critically Endangered White-bellied Heron (Ardea insignis).
  • The Lohit River basin in Arunachal Pradesh supports about 70% of India's White-bellied Heron population, with only 6–9 individuals remaining in the country.
  • The species has been listed as Critically Endangered on the IUCN Red List since 2007 and is protected under Schedule I of the Wildlife (Protection) Act, 1972.
  • The proposed dam may alter river flow, water turbidity, and riparian forests, affecting the bird's feeding and nesting habitats.
  • The environmental impact assessment (EIA) for the project did not include the White-bellied Heron, despite its presence in the Lohit River basin.
