India’s rarest heron faces a silent end as new dam ignores its home
A proposed hydropower project in Arunachal Pradesh has raised concerns over habitat loss for India’s rarest heron and the limits of project-level environmental assessment in river-basin planning.
- The white-bellied heron depends on fast-flowing rivers, shallow feeding areas, and mature riparian forests for breeding, roosting, and feeding.
- The Forest Advisory Committee granted in-principle clearance to the proposed hydropower project in the Lohit river basin.
- Local communities said the environmental assessment left out key flora, fauna, social impacts, cultural practices, and some villages.
A conservation report on the Lohit river basin in Arunachal Pradesh warns that a proposed 1,200-MW hydropower project could push India’s white-bellied heron toward local extinction. The issue is not only one of species protection; it also raises a larger UPSC-relevant question about whether project-level environmental appraisal can capture the ecological value of a connected river-basin habitat.
What the conservation report says
The conservation report says the white-bellied heron is extremely elusive and depends on healthy, fast-flowing rivers with mature riparian forests. It says only a very small number of the birds survive in India and that a majority of the known Indian presence is associated with the Lohit basin.
UPSC may link the white-bellied heron case to biodiversity protection, environmental impact assessment, compensatory afforestation, and river-basin planning. A likely mains framing is whether project-level clearance can adequately assess cumulative ecological impacts in fragile Himalayan and North-Eastern river systems.
