What is the common examiner trap about Environment in UPSC exams?

The examiner may ask about the IUCN status of the white-bellied heron and confuse it with other heron species. Also may ask about the role of the Forest Advisory Committee vs. National Board for Wildlife.

What should UPSC aspirants remember about Environment for Prelims?

1. Target this Data: Critically endangered since 2007; India population 6-9 individuals; 1,200 MW; 33,000 trees felled. 2. Target this Nodal Body: Forest Advisory Committee under Union Environment Ministry. 3. Target this Legal Point: Schedule I of Wildlife Protection Act 1972.

Critically Endangered White-Bellied Heron Faces Extinction as 1,200 MW Lohit Dam Clears Forest Panel

Q: Which committee under the Union Environment Ministry grants in-principle clearance for hydroelectric projects involving forest land?

Forest Advisory Committee, The Forest Advisory Committee (FAC) is a statutory body under the Ministry of Environment, Forest and Climate Change that evaluates proposals for diversion of forest land for non-forest purposes, including hydroelectric projects. The National Board for Wildlife deals with wildlife clearance, while the other options are not relevant for forest land diversion.

Q: Consider the following statements: 1. White-bellied heron is listed as Critically Endangered on the IUCN Red List since 2007. 2. The species is currently found in the Teesta region of India. 3. It is protected under Schedule I of the Wildlife Protection Act 1972. Which of the statements given above is/are correct?

Both 1 and 3, Statement 1 is correct: the white-bellied heron has been Critically Endangered since 2007. Statement 2 is incorrect: the species was first described from the Teesta region but is now locally extinct there. Statement 3 is correct: it is listed in Schedule I of the Wildlife Protection Act 1972, offering the highest legal protection. Hence option C is correct.

Q: What is the installed capacity of the proposed hydroelectric project on the Lohit River?

1,200 MW, The article explicitly states that the Forest Advisory Committee granted in-principle clearance to a 1,200 MW hydroelectric power project on the Lohit River. The other options are plausible distractors but do not match the data.

Q: What is the primary reason for the likely local extinction of white-bellied herons due to the Lohit dam?

Change in water turbidity and flow affecting foraging, The article explains that the dam will alter the water's turbidity and flow, which is critical for the heron's unique foraging strategy. The heron hunts in shallow water and feeds exclusively on fish. Changes in water conditions will disrupt its ability to catch prey, leading to local extinction. While human disturbance is a factor, the primary mechanism is hydrological alteration.

What This Article Covers

1.White-bellied heron (Ardea insignis) is critically endangered with only 6-9 individuals in India across three rivers; 70% in Lohit basin.

2.Forest Advisory Committee under Union Environment Ministry cleared 1,200 MW dam that will fell 33,000+ trees, ignoring the species in EIA.

3.Dam will alter water turbidity and flow, leading to potential local extinction; species is in Schedule I of Wildlife Protection Act 1972.

The Big Picture

Prelims · HighMains · High

The white-bellied heron, India's rarest heron and critically endangered since 2007, faces local extinction due to a 1,200 MW hydroelectric project on the Lohit River in Arunachal Pradesh. The Forest Advisory Committee granted in-principle clearance despite the species being omitted from the environmental impact assessment. This highlights gaps in environmental governance and the need for basin-level conservation planning.

White-Bellied Heron Crisis

India's rarest heron, with only 6-9 individuals in the wild, faces local extinction from the Lohit dam project.

Dam Clearance Controversy

Forest Advisory Committee granted in-principle clearance for 1,200 MW dam despite omission of the species from the EIA.

🏞️

Basin-Level Conservation Needed

Experts call for a basin-level approach to assess impacts on the heron's habitat across the Lohit river basin.

Detailed Analysis & Strategic Depth

Context / Background

The white-bellied heron (Ardea insignis) was first scientifically described in 1878 by Allan Octavian Hume from the Teesta region, where it is now locally extinct. Today, it is restricted to pockets of Arunachal Pradesh, Bhutan, and Myanmar, inhabiting fast-flowing Himalayan rivers up to 1,500 m elevation. It has been listed as Critically Endangered on the IUCN Red List since 2007. In India, only 6-9 individuals survive across three rivers: Noa-Dehing, Lahm, and Lohit, with 70% concentrated in the Lohit basin.

Core Analysis & Implications

The 1,200 MW hydroelectric project on the Lohit River, developed by Tehri Hydro Development Corporation in partnership with the Arunachal Pradesh government, received in-principle clearance from the Forest Advisory Committee despite its environmental impact assessment (EIA) omitting the white-bellied heron. The dam will submerge mature riparian forests critical for nesting and alter water turbidity and flow, directly threatening the heron's specialized foraging strategy (fish-only diet in shallow water). The compensatory afforestation proposed in Madhya Pradesh (over 1,000 km away) is ecologically inadequate, as natural forests cannot be recreated. Local communities have opposed the project since 2008, citing submerged land and exclusion of cultural practices from the EIA.

Future Outlook / Way Forward

Experts recommend a basin-level impact assessment for the Lohit basin rather than site-specific analysis, and the establishment of conservation breeding centres similar to Bhutan's programme. Stronger implementation of existing policies, prevention of illegal sand extraction, monitoring water quality, and limiting tourism disturbance are essential. Conservation planning must move beyond charismatic species like tigers to give equal urgency to rare species like the white-bellied heron. The case underscores the persistent gap between strong policies on paper and effective on-ground implementation.

SC-NBWL Clears 1,800 MW Hydropower Project in Panna-Ranipur Tiger Corridor Despite DFO Concerns

The Standing Committee of the National Board for Wildlife (SC-NBWL) has recommended clearance for a 1,800 MW pumped storage hydropower project in the Panna-Ranipur tiger corridor, overruling objections from a Madhya Pradesh forest officer who warned of corridor fragmentation. The project requires 411.48 hectares of forest land and will be allowed with mitigation measures including three wildlife overpasses. This decision highlights the tension between renewable energy expansion and wildlife conservation.
