"Lost World" New Garden of Eden?

The team recorded
new butterflies,
frogs, and a series
of remarkable
plants that included
five new palms and
a giant
rhododendron flower.

The survey also found a honeyeater bird that was "previously unknown to science".
The research group - from the US, Indonesia and Australia - trekked through an area in the mist-shrouded Foja
Mountains, located just north of the vast Mamberamo Basin of north-western (Indonesian) New Guinea.
The researchers spent nearly a month in the locality, detailing the wildlife and plant life from the lower hills to near
the summit of the Foja range, which reaches more than 2,000m in elevation.

"It's beautiful, untouched, unpopulated forest; there's no evidence of human impact or presence up in these
mountains," Dr Beehler told the BBC News website. "We were dropped in by helicopter. There's not a trail
anywhere; it was really hard to get around."
He said that even two local indigenous groups, the Kwerba and Papasena people, customary landowners of the
forest who accompanied the scientists, were astonished at the area's isolation. "The men from the local villages
came with us and they made it clear that no one they knew had been anywhere near this area - not even their
ancestors," Mr Beehler said.

Unafraid of humans

One of the team's most remarkable discoveries was a honeyeater bird with a bright orange patch on its face - the
first new bird species to be sighted on the island of New Guinea in more than 60 years.
The researchers also solved a major ornithological mystery - the location of the homeland of Berlepsch's six-wired
bird of paradise. First described in the late 19th Century through specimens collected by indigenous hunters from
an unknown location on New Guinea, the species had been the focus of several subsequent expeditions that failed
to find it. On only the second day of the team's expedition, the amazed scientists watched as a male Berlepsch's
bird of paradise performed a mating dance for an attending female in the field camp. It was the first time a live male
of the species had been observed by Western scientists, and proved that the Foja Mountains was the species' true
home.
"This bird had been filed away and forgotten; it had been lost. To rediscover it was, for me, in some ways, more
exciting than finding the honeyeater. I spent 20 years working on birds of paradise; they're pretty darn sexy
beasts," Dr Beehler enthused.

The team also recorded a golden-mantled tree kangaroo, which was previously thought to have been hunted to
near-extinction. Mr Beehler said some of the creatures the team came into contact with were remarkably unafraid of
humans. Two long-beaked echidnas, primitive egg-laying mammals, even allowed scientists to pick them up and
bring them back to their camp to be studied, he added.

The December 2005 expedition was organised by the US-based organisation Conservation International, together
with the Indonesian Institute of Sciences. The team says it did not have nearly enough time during its expedition to
survey the area completely and intends to return later in the year.
The locality lies within a protected zone and Dr Beehler believes its future is secure in the short term.
"The key investment is the local communities. Their knowledge, appreciation and oral traditions are so important.
They are the forest stewards who will look after these assets," Dr Beehler told the BBC.
