How does a critically endangered species, one with fewer than 250 individuals left on Earth, get left out of the very environmental assessment designed to catch exactly this kind of risk? The answer, for the white-bellied heron, comes down to where officials drew a line on a map.SUMMARY: The Forest Advisory Committee under the Union Environment Ministry has granted in-principle clearance to the 1,200-MW Kalai-II hydroelectric project on the Lohit River in Arunachal Pradesh, which will fell more than 33,000 trees. The project's environmental impact assessment did not include the white-bellied heron, a critically endangered species of which the Lohit basin holds an estimated 70% of India's entire population. State officials told the Forest Advisory Committee the bird was excluded because it had not been recorded within the project's narrow "diversion area." The Committee's clearance permits compensatory afforestation in Madhya Pradesh, more than a thousand kilometres from the Lohit basin.

Where India's EIA Framework Breaks Down for Basin-Level Species

The target here isn't ambiguous: the Environment (Protection) Act mandates that impact assessments identify and account for species affected by a project before clearance is granted. The data shows that requirement wasn't met - not through concealment, but through a definitional choice that made non-compliance technically defensible.

The Specific Point Where the Assessment Failed

State officials told the Forest Advisory Committee the heron wasn't included because it "had not been recorded within the project's diversion area"

• the narrow construction footprint, not the river basin the bird actually depends on. This isn't a data-collection failure; WAPCOS's surveyors likely did record what was physically present at the dam site. The failure is structural: an EIA methodology that treats "the project area" as synonymous with "the ecological system the project affects" will always miss species like the white-bellied heron, which forages and nests along stretches of river far beyond any single construction footprint. Bida's own framing - that Lohit needs to be "assessed as one connected habitat" rather than a series of isolated sites - names the exact fix a diversion-area methodology structurally cannot deliver.

Why the Compensatory Afforestation Compounds the Same Error The Forest Advisory

Committee's consent allows afforestation in Madhya Pradesh, over a thousand kilometres from the Lohit basin, to offset the loss of 33,000 Eastern Himalayan trees. This is the same site-specific logic applied a second time: compliance is measured by hectares planted, not by whether the specific riparian, old-growth forest structure the heron needs for nesting is replaceable anywhere, let alone in a different biogeographic zone entirely.

Krishna's point - that "natural forests... cannot be fully recreated through human interventions"

• isn't a general environmental lament here. It's the precise reason a paperwork-complete afforestation plan can coexist with a real, unaddressed extinction risk for a species with fewer than 250 individuals left globally. The exam-relevant insight: this case is a clean illustration of how EIA "adequacy" and actual ecological adequacy diverge whenever a project's legal boundary is smaller than the species' actual range - a gap no amount of hectare-for-hectare afforestation compensation can close.
