The Namdapha National Park is located in Arunachal Pradesh's Changlang district. It is a biodiversity hotspot in the Eastern Himalayas, with over 1,000 floral and 1,400 faunal species. It also has a large number of dipterocarp forests.
• Namdapha National Park is India's fourth-largest national park by area.
• Namdapha National Park is nestled between the Patkai and Dapha bum ranges of Mishmi Hills in the Eastern Himalayan Sub-region.
• Namdapha is located on the international border between India and Myanmar, along the raging Noa-Dihing River.
• In 1972, Namdapha was designated as a wildlife sanctuary. In 1983, it was designated as a tiger reserve and national park. The park's total area is approximately 1807.82 km2.
• At 27°N latitude, the park contains the world's northernmost lowland evergreen rainforests, making it one of India's most biodiverse areas. The Patkai hills to the south and south-east, and the Himalaya to the north, flank Namdapha and its surrounding areas, which are close to the Indo-Myanmar-China tri-junction.
• The area is sandwiched between the Palearctic and Indo-Malayan bio-geographic zones, resulting in a plethora of species. To complement the secondary forests, the park has extensive bamboo forests.
• It is the world's only park with the four feline species of big cat, the Tiger (Panthera Tigris), Leopard (Panthera Pardus), Snow Leopard (Panthera Uncia), and Clouded Leopard (Neofelis Nebulosa), as well as a large number of Lesser cats.
• The park is home to a variety of primate species, including the Assamese macaque, pig-tailed macaque, stump-tailed macaque, and a large number of the distinctive Hoolock Gibbons (Hylobates Hoolock), India's only "ape" species.
• There are approximately 96 mammal species found here, 29 of which are listed on Schedule I of the Wildlife (Protection) Act of 1972.
• Perhaps no other national park in the world has a greater range of altitude than Namdapha, which rises from 200 metres to 4,500 metres in the snow-capped mountains. With increasing altitude, the habitat
shifts from tropical moist forests to montane forests, temperate forests, and, at higher elevations, Alpine meadows and perennial snow.
• During the Second World War, Namdapha rose to prominence. It was located on the famous ‘hump' air route connecting Assam and China, which the Allies used to support Chian Kai Shek's Kuo Min Tang army.
• The Namdapha area also served as a refugee camp for many immigrants, including the Chakma, Bangladeshi refugees.
• For the majority of the year, the higher elevations are snowbound. The park's highest point (4571 m) is Dapha Bum, a ridge on the Mishmi hills. In addition to the primary forests, the park has extensive bamboo forests and secondary forests.
• DOMINANT FLORA:
The park is home to a diverse range of floral species. Many of the plants that can be found in Namdapha are rare, endangered, or endemic. This region is home to endemic Amentotaxus, Cephalotaxus, and Larix species. Pinus merkusii (Sumatran pine) and Abies delavayi (Delavay's Fir) are two species that are only found in India. The Blue Vanda, one of the rarest and most endangered orchids, can be found here. The most well-known local medicinal plant, Mishimi Teeta (Copti teeta), which is used by local tribals for a variety of ailments, is available here, but export is prohibited.
