Two mammals thought to be new to science discovered in Indonesia

19/10/2006 00:00:00 December 2007. A tiny possum and a giant rat, almost certainly new species, have been found by scientists on a recent expedition to Indonesia’s remote and virtually unknown Foja Mountains in the pristine wilderness of western New Guinea.

‘It’s comforting to know that there is a place on earth so isolated that it remains the absolute realm of wild nature,’ said Conservation International (CI) Vice President Bruce Beehler, who led the expedition. ‘We were pleased to see that this little piece of Eden remains as pristine and enchanting as it was when we first visited.’
Two new Mammal Species
During the June expedition, the team documented two mammals, a Cercartetus pygmy possum, one of the world’s smallest marsupials, and a Mallomys giant rat, both currently under study and apparently new to science. They also recorded the mating displays of several rare and little-known birds for the first time.
‘The giant rat is about five times the size of a typical city rat,’ said Kristofer Helgen, a scientist with the Smithsonian Institution in Washington, D.C. ‘With no fear of humans, it apparently came into the camp several times during the trip.’

First Film of Rare Birds
The film crew obtained the first film documentation of several spectacular birds found in Foja, capturing on tape the full courtship displays of the golden-fronted bowerbird (Amblyornis flavifrons) and of the black sicklebill bird of paradise (Epimachus fastuosus).

They also recorded the ‘lost’ Bird of Paradise – Parotia berlepschi (known as Berlepsch’s six-wired bird of paradise), and the newly described wattled smoky honeyeater (Melipotes carolae), both known only from the Foja Mountains.

The Foja Wilderness is part of the great Mamberamo Basin, the largest virgin tropical forest in the Asia Pacific region. As the global community searches for solutions to climate change, large untouched forested areas such as these will become more and more valuable as essential carbon sinks.

The cutting and burning of tropical forests worldwide emits at least 20 percent of total global greenhouse gases. Protecting these forests minimizes the impact of climate change while providing direct benefits to local populations, such as fresh water, clean air, food, seed dispersal, pollination and sources of medicines.

The Indonesian Government has declared the region a National Wildlife Sanctuary, and CI continues to work with the government and local communities to build on this conservation success and ensure even greater protection of the area.
CI and LIPI plan another expedition back to the Foja Mountains in late 2008 or 2009. This proposed expedition will seek to survey the summit forests of the highest peak, and the little-studied lower montane elevations. They expect to find additional new species of frogs, mammals, butterflies, and plants.

Conservation International (CI) and Indonesia Institute of Science (LIPI) scientists were accompanied by the first film crew to obtain footage of the region and its wildlife on an expedition to the Fojas in June 2007. A National Geographic photographer/scientist and a CBS News camera crew joined the team as they returned to the mountains. CI and LIPI scientists discovered dozens of new plants and animals on their first expedition to the region in late 2005. An account of the 2007 expedition was aired on the CBS News program, ‘60 Minutes’ on Dec. 16.
