Mountain range in Indonesia

The Foja Mountains (Foja Range, Foya Mountains) are located just north of the Mamberamo river basin in Papua, Indonesia. The mountains rise to , 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 Foja Range languages are spoken within the mountain range and nearby areas.

The Foja Mountains are cooler than the lowlands below because of their elevation, but January and July temperatures still average The rainy season is from December to March, but the area can receive rain throughout the year. In a typical year, the range receives more than of precipitation. Relative humidity ranges from 73 to 87%. The nearest villages include Sragafareh, Jomen, Beggensabah, Aer Mati, and Dabra.

The mountains have no record of visitors prior to 1979 (Stattersfield et al. 1998). Much of the area around the Foja Mountains and nearby Van Rees Mountains are too steep for conventional logging, and are considered unsafe due to their inaccessibility. Some atlases show only the Gauttier Mountains in the area, but the Foja Mountains lie at the eastern edge of that range at about 139° east longitude.

The portion of the mountains above 1000 meters elevation is in the Northern New Guinea montane rain forests ecoregion. The montane forests are dominated by Araucaria cunninghamii, Podocarpus idenburgensis, Agathis labillardieri, Calophyllum, and Palaquium at the 1,200 meter level. The mountains are within the Mamberamo Foja Wildlife Reserve.

In December 2007, a second scientific expedition was taken to the mountain range. The expedition led to the discovery of two new species: the first being a 1.4  kg giant rat (Mallomys sp.) approximately five times the size of a regular brown rat, the second a pygmy possum (Cercartetus sp.) described by scientists as "one of the world's smallest marsupials."

An expedition late in 2008, backed by the Indonesian Institute of Sciences, National Geographic Society and Smithsonian Institution, was made in order to assess the area's biodiversity. New types of animals recorded include a frog with a long erectile nose, a large woolly rat, an imperial pigeon with rust, grey and white plumage, a 25 cm gecko with claws rather than pads on its toes, and a small, 30 cm high, black forest wallaby (a member of the genus Dorcopsis).
