Key Highlights
- Bhitarkanika spans roughly 650 km² across the Brahmani‑Baitarani deltas in Odisha, adjoining the Bay of Bengal.
- The region evolved from private zamindari holdings to a wildlife sanctuary in 1975, a national park in 1998, and earned Ramsar wetland status in 2002.
- More than 60 mangrove species coexist with salt‑water crocodiles, king cobras, pythons, water monitors and over 260 bird species.
- Gahirmatha Beach, part of its coastline, functions as a principal nesting site for Olive‑Ridley sea turtles each January through March.
- Since 1983, legislation has prohibited the capture or disturbance of turtles and their eggs.
Detailed Insights
Located in the eastern Indian state of Odisha, the Bhitarkanika mangrove complex occupies the confluence of the Brahmani and Baitarani river deltas before meeting the Bay of Bengal. Covering an estimated 650 square kilometres, the wetland supports an intricate web of life that thrives in brackish water and tidal mudflats.
The area’s administrative journey began under the control of zamindars until the abolition of the zamindari system in 1952, after which the Odisha government assumed stewardship. Recognizing its ecological value, the government designated Bhitarkanika a wildlife sanctuary in 1975, later carving out a core zone as Bhitarkanika National Park in 1998. International acknowledgment arrived in 2002 when the site was listed under the Ramsar Convention, underscoring its global significance.
Botanically, the mangrove forest hosts approximately 62 distinct species, including members of the genera Avicennia, Bruguiera, and Rhizophora. The faunal assemblage is equally diverse: salt‑water crocodiles dominate the aquatic predators, while reptiles such as king cobras, Indian pythons, and water monitors roam the forest floor. Ornithologists have recorded more than 260 bird species between 2004 and 2006, encompassing resident, migratory, and wintering populations.
Perhaps the most celebrated seasonal phenomenon is the arrival of Olive‑Ridley turtles (Lepidochelys olivacea) on Gahirmatha Beach. From January to March, thousands of females emerge to deposit clutches of eggs in the sand. Prior to 1983, local exploitation of these turtles was common, but a protective ordinance enacted that year now criminalizes any harm to the turtles or their nests.
