Explanation: Bhitarkanika National Park is a significant ecological site located in the Kendrapara district of Odisha, India. The park is renowned for its mangrove forests and rich biodiversity, including the saltwater crocodile, which is one of the largest reptiles in the world. The park is situated at the confluence of two major rivers: the Brahmani and the Baitarani.
The Brahmani River originates in the Chota Nagpur Plateau in Jharkhand and flows through Odisha before merging with the Baitarani River. The Baitarani River, on the other hand, originates in the Eastern Ghats in Odisha and also flows through the state. The confluence of these two rivers forms a vast deltaic region, which is the site of Bhitarkanika National Park.
This unique geographical feature is crucial for the park's ecological significance. The confluence of the two rivers creates a diverse ecosystem that supports a wide range of flora and fauna. The mangrove forests in the park are particularly important as they provide a habitat for various species and play a vital role in coastal protection and carbon sequestration.
The park's location at the confluence of the Brahmani and Baitarani rivers also makes it a significant site for studying riverine ecosystems and the impact of river confluences on biodiversity. The park is managed by the Odisha Forest Department and is a protected area under the Indian Wildlife (Protection) Act, 1972.
In summary, Bhitarkanika National Park is the correct answer because it is located at the confluence of the Brahmani and Baitarani rivers, with the Brahmani originating in Jharkhand and the Baitarani in Odisha. This unique geographical feature makes it a significant ecological site and distinguishes it from the other national parks mentioned in the options.
