Mount Bosavi

The Bosavi (Mount Bosavi ) is a 2507 m high mountain in the Southern Highlands Province of Papua New Guinea. It is located on the Great Papuan Plateau and is part of the Kikoribeckens. Bosavi is a heavily eroded volcano with a caldera, which opens to the south. The crater is about 4 km wide and 1 km deep. The extinct volcano rises 2000 m above the surrounding level him. Its last eruption occurred 200,000 years ago.

Mount Bosavi is home to a unique species. An international expedition with the participation of scientists from the Smithsonian National Museum of Natural History in Washington, and a television crew from the Natural History Unit of the BBC discovered in 2009 more than 40 previously unknown species, including 16 frogs, three fish, a bat and a rat with the still unofficial name Bosavi wool rat, which probably belongs to the giant tree rats, and has a length of about 82 cm and a weight of about 1.5 kg, the largest rats in the world.

A part of the mountain is part of the Sulamesi Wildlife Management Area, which was established in 2006. It is part of the proposed UNESCO World Heritage Site Kikori-Becken/Großes Papua plateau.

The people who live north of Mount Bosavi, refer to themselves as Bosavi Kalu ( people of Bosavi ) and divide into four identical culturally, but linguistically different groups, the Kaluli, Ologo, Walulu and Wisesi. Together they are called Bosavi.
