Previous Year Question

Namdapha National Park is located in the Changlang district of Arunachal Pradesh, near the Eastern Himalayan and India-Myanmar biogeographical regions.

Because of its exceptionally wide altitudinal range, the national park displays remarkable climatic and vegetation diversity, extending from tropical conditions to high-altitude snow-covered environments.

The park’s elevation extends from approximately 200 metres in the lower river valleys to mountain peaks exceeding 4,500 metres.

The lower-altitude areas contain warm and humid tropical evergreen and semi-evergreen forests.

With increasing elevation, the vegetation changes into subtropical broadleaf forests.

These are followed by temperate broadleaf forests, coniferous forests, subalpine vegetation and high-altitude grasslands.

The highest regions have extremely cold, snow-covered and tundra-like conditions, described as an ‘arctic’ climate in the question.

Here, ‘arctic’ does not mean the actual northern polar region but the extremely cold glacial and alpine conditions produced by altitude.

The Namdapha and Noa-Dihing rivers and their tributaries play an important role in the hydrology of this protected landscape.

Namdapha was accorded the status of a national park and tiger reserve in 1983.

It is particularly famous for the possible presence of four large felids—the tiger, leopard, clouded leopard and snow leopard.

It also supports the red panda, hoolock gibbon, Mishmi takin, elephant and several hornbill species.

Khangchendzonga National Park is located in the high-Himalayan region of Sikkim and is mainly associated with temperate, subalpine, alpine and glacial ecosystems.

Nanda Devi National Park is located in the high Himalayas of Uttarakhand and is primarily a subalpine and alpine environment.

Neora Valley National Park is situated in the Eastern Himalayas of West Bengal and contains vegetation ranging from subtropical to temperate and subalpine, but it does not possess the same tropical-to-arctic sequence as Namdapha.
