Castanopsis acuminatissima is an evergreen tree native to Southeast Asia and New Guinea. It is known by a variety of common names over its range, including white oak, New Guinea oak, Papua New Guinea oak, ki riung, ko-duai, ko-soi, ko-mat, meranak, and riung anak. [2]
Castanopsis acuminatissima is a large canopy tree, up to 40 meters in height. The trunk is markedly fluted, and sometimes buttressed. The bark is grey or pale brown, rough and fissured, less than 25 mm thick, with red under-bark.
Leaves are simple, 9.0-11.5 cm long and 2.5-3.5 cm wide, and arranged spirally along the branches. Fruits are simple nuts, 1–10 mm in diameter. [3]
Castanopsis acuminatissima ranges from southwestern China (Guizhou and Yunnan provinces) through Indochina (Laos, Myanmar, Thailand, Vietnam, and the Chittagong Hills of Bangladesh) and Malesia (Malaysia; the islands of Sulawesi, Java, Kalimantan, and Sumatra, in Indonesia; the islands of New Guinea (West Papua in Indonesia and Papua New Guinea) and New Britain (Papua New Guinea)). [4] [5]
Castanopsis acuminatissima is native to lowland dipterocarp rain forests and montane rain forests from 300 up to 2,500 meters elevation. [1]
In New Guinea and New Britain, it is a predominant tree in the lower montane forests, lying between 900-1000 and 2000 meters elevation. [6] It can also be found at lower elevations on small-crowned hill forests, in association with Hopea papuana and the drought-tolerant Casuarina papuana . [7]
Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location.
The Foja Mountains are located just north of the Mamberamo river basin in Papua, Indonesia. The mountains rise to 2,193 metres (7,195 ft), and have 3,000 square kilometers of old growth tropical rainforest in the interior part of the range. The Foja forest tract covers 9,712 square kilometers and is the largest tropical forest without roads in the Asia Pacific region.

The pygmy ringtail possum is a species of marsupial in the family Pseudocheiridae. It is found in the montane forest regions of Papua New Guinea and West Papua, Indonesia. They are "widespread along the Central Cordillera" and live at elevations between 1,500 and 3,600 metres above sea level.”
The New Guinea Highlands, also known as the Central Range or Central Cordillera, is a long chain of mountain ranges on the island of New Guinea, including the island's tallest peak, Puncak Jaya, Indonesia, 16,024 ft (4,884 m), the highest mountain in Oceania. The range is home to many intermountain river valleys, many of which support thriving agricultural communities. The highlands run generally east-west the length of the island, which is divided politically between Indonesia in the west and Papua New Guinea in the east.
The Central Range montane rain forests is a tropical moist forest ecoregion on the island of New Guinea. The ecoregion covers the Central Range of the New Guinea Highlands, which extends along the spine of the island. The montane rain forests of the ecoregion are distinct from the surrounding lowland forests, and are home to many endemic plants and animals.
