Bhitarkanika National Park

Bhitarkanika National Park occupies the deltaic floodplain formed by the Brahmani, Baitarani and Dhamra rivers in Kendrapara district, Odisha, on the eastern coast of India along the Bay of Bengal. The area was first notified as the Bhitarkanika Wildlife Sanctuary in 1975 under the Wildlife (Protection) Act, 1972, against the backdrop of post-independence concern over the collapse of saltwater crocodile numbers. The core of that sanctuary—covering approximately 145 square kilometres—was upgraded to national park status by the Government of Odisha on 16 September 1998, conferring the highest statutory protection available under Indian wildlife law. The surrounding sanctuary, the Gahirmatha Marine Sanctuary, and the broader Bhitarkanika mangrove wetland together form an integrated conservation landscape that extends the legal regime over the larger estuary.

The legal architecture governing the park operates on three reinforcing tiers. The national park designation under Section 35 of the Wildlife (Protection) Act prohibits grazing, settlement, and the extraction of forest produce within the core, and bars the destruction or diversion of habitat except by state legislative resolution. Layered above this is the park's listing as a Ramsar Site of international importance on 19 August 2002 (the Bhitarkanika Mangroves), which obliges India to maintain the ecological character of the wetland under the 1971 Ramsar Convention and to report changes to the Convention Secretariat. The adjoining Gahirmatha coast, the largest mass-nesting ground of the olive ridley sea turtle in the world, is regulated separately as a marine sanctuary, with seasonal fishing restrictions enforced through the Odisha Marine Fishing Regulation Act and the deployment of patrol vessels by the Forest Department and Coast Guard.

Conservation management combines habitat protection with species recovery programmes. The crocodile rearing and rehabilitation programme launched at Dangmal in 1975, supported by the United Nations Development Programme and the Food and Agriculture Organization, pioneered the "rear and release" technique that lifted the saltwater crocodile (Crocodylus porosus) from near-extirpation to a stable wild population now exceeding seventeen hundred individuals by recent annual census counts. The park sustains India's second-largest mangrove forest after the Sundarbans, with over sixty mangrove and associated species, and supports the Indian python, water monitor, wild boar, spotted deer, and a heronry at Bagagahana that hosts tens of thousands of nesting waterbirds. Mangrove zones buffer the coastline against cyclonic surge—a function dramatically demonstrated during the 1999 Odisha Super Cyclone.

Contemporary administration rests with the Bhitarkanika National Park Division of the Odisha Forest and Environment Department, headquartered at Rajnagar, with field stations at Dangmal, Habalikhati and Gupti. The annual saltwater crocodile census, conducted each January by departmental teams, draws national press coverage and informs the National Crocodile Conservation Project supervised by the Ministry of Environment, Forest and Climate Change in New Delhi. The Gahirmatha turtle nesting season, peaking between February and April, prompts an annual fishing ban enforced from November through May, a recurring point of negotiation between the state government and coastal fishing communities. In 2023 and 2024, Gahirmatha recorded mass arribada nesting events involving several hundred thousand olive ridleys, reaffirming the park's standing in global marine conservation.

Bhitarkanika should be distinguished from adjacent legal and geographic categories. A national park differs from a wildlife sanctuary in that the former extinguishes private rights entirely while the latter may permit certain regulated activities; Bhitarkanika exists as a national park nested within a larger sanctuary, a layered status common in Indian protected-area design. It is not a tiger reserve, which carries a distinct designation and central funding under Project Tiger and the National Tiger Conservation Authority. Nor is it a biosphere reserve under the UNESCO Man and the Biosphere Programme, though its mangrove ecology is comparable to the Sundarbans Biosphere Reserve in West Bengal. Its Ramsar listing classifies it among wetlands of international importance, a separate instrument from the World Heritage Convention, under which the Sundarbans—but not Bhitarkanika—is inscribed.

The park sits at the centre of recurring policy controversies. Proposals to develop the deep-water port at Dhamra, adjacent to the turtle nesting grounds, drew sustained litigation and objections from conservation organisations during the 2000s over lighting and dredging impacts on olive ridley navigation. Saltwater intrusion, embankment failure, and the encroachment of aquaculture and human settlement at the park periphery continue to pressure the buffer zone. Cyclonic events, including Phailin in 2013, Fani in 2019, and Yaas in 2021, have repeatedly tested the mangrove buffer and damaged forest department infrastructure, sharpening debate over climate adaptation funding for India's eastern littoral and the relocation of villages within ecologically sensitive zones.

For the working practitioner—particularly the civil-services aspirant preparing General Studies Paper III—Bhitarkanika functions as a compact case study in environmental governance: the interplay of domestic wildlife statute, international wetland obligation, species-specific recovery science, and the trade-offs between port-led development and coastal ecology. It illustrates how a single landscape can carry overlapping designations, why mangroves are treated as natural disaster infrastructure in coastal policy, and how India operationalises its commitments under the Ramsar Convention. Desk officers and environmental journalists encounter Bhitarkanika whenever the annual crocodile census, the Gahirmatha arribada, or fishing-ban disputes return to the news cycle, making fluency in its legal status and ecological significance a practical asset.
