Synonyms | |
Horsfieldia kingii is a dioecious tree of the family Myristicaceae. It grows up to 20 m tall [4] and has large seeds that are dispersed by frugivores such as hornbills and imperial pigeons. [5] The fruiting period is from February to May. [6] The fruit is an arillate capsule and is bi-coloured. [5]
The plant is referred to as ramtamul in Assamese language and is sometimes used as a substitute for betelnut. However, they could be mildly intoxicating to humans. [4] The leaves form a part of the diet of the endangered capped langur. [7]
A frugivore is an animal that thrives mostly on raw fruits, succulent fruit-like vegetables, roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is called mutualism.
The great hornbill also known as the concave-casqued hornbill, great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family. It is found in the Indian subcontinent and Southeast Asia. Its impressive size and colour have made it important in many tribal cultures and rituals. The great hornbill is long-lived, living for nearly 50 years in captivity. It is predominantly frugivorous, but is an opportunist and will prey on small mammals, reptiles and birds.

The rufous-necked hornbill is a species of hornbill in Bhutan, northeastern India, especially in Arunachal Pradesh, Indian Subcontinent and Southeast Asia. It is locally extinct in Nepal due to hunting and significant loss of habitat. There are < 10,000 adults left in the wild. With a length of about 117 centimetres (46 in), it is among the largest Bucerotine hornbills. The underparts, neck and head are rich rufous in the male, but black in the female.

Namdapha National Park is a 1,985 km2 (766 sq mi) large protected area in Arunachal Pradesh of Northeast India. With more than 1,000 floral and about 1,400 faunal species, it is a biodiversity hotspot in the Eastern Himalayas. The national park harbours the northernmost lowland evergreen rainforests in the world at 27°N latitude. It also harbours extensive dipterocarp forests, comprising the northwestern parts of the Mizoram-Manipur-Kachin rain forests ecoregion.
Eaglenest or Eagle's Nest Wildlife Sanctuary is a protected area of India in the Himalayan foothills of West Kameng District, Arunachal Pradesh. It conjoins Sessa Orchid Sanctuary to the northeast and Pakhui Tiger Reserve across the Kameng river to the east. Altitude ranges are extreme: from 500 metres (1,640 ft) to 3,250 metres (10,663 ft). It is a part of the Kameng Elephant Reserve.
The Narcondam hornbill is a species of hornbill in the family Bucerotidae. It is endemic to the Indian island of Narcondam in the Andamans. Males and females have a distinct plumage. The Narcondam hornbill has the smallest home range out of all the species of Asian hornbills.

The capped langur is a species of primate in the family Cercopithecidae. It is found in Bangladesh, Bhutan, India, and Myanmar. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. They are arboreal and gregarious by nature. A herd of capped langur consists of 2 to 14 langurs led by a brawny male langur. They are herbivorous, ingesting leaves, twigs, buds and fruits.
Aglaia spectabilis is a species of tree in the family Meliaceae, found from the Santa Cruz Islands in the southwest Pacific to Queensland (Australia), Southeast Asia, Yunnan (Zhōngguó/China) and the Indian subcontinent. It grows from a 1m shrub to an emergent 40m tall tree, depending on the habitat. Its wood is commercially exploited as timber, but otherwise is of poor quality with limited use. The fruit are eaten, and used in folk medicine. The seeds are large in comparison to other plants, and a major source of dispersal of the species are hornbills eating the fruit, flying away from the tree and regurgitating the seeds.
The Kameng River in the eastern Himalayan mountains, originates in Tawang district from the glacial lake below snow-capped Gori Chen mountain 27°48′36″N92°26′38″E, elevation 6,300 metres (20,669 ft), on the India-Tibet border in South Tibet and flows through Bhalukpong circle of West Kameng District, Arunachal Pradesh and Sonitpur District of Assam, India.

Sessa Orchid Sanctuary is a 100 km2 protected area of India in the Himalayan foothills in Bhalukpong Forest Division of West Kameng District, Arunachal Pradesh. It conjoins Eaglenest Wildlife Sanctuary to the southwest. It is a part of the Kameng Protected Area Complex (KPAC), which is an Elephant Reserve. See map. The department of Environment & Forests has developed trekking routes for visitors to enjoy the natural habitats of orchids. There are deep gorges and valleys, high peaks and rugged terrain that are rewarding for nature lovers and adventure tourists. A nursery includes representative specimens of various orchid species of the sanctuary and a demonstration farm of Cymbidium hybrids for cut-flower production. Most of Sessa has traditionally been claimed by the Bugun tribe as part of their territory.
