A team of scientists in Papua New Guinea believes it has discovered at least 80 new species of flora and fauna.
The newspaper, The National, says the discovery was made by scientists led by the US based Wildlife Conservation Society during a month-long expedition at the Hindenburg Wall, in the mountains of Western Province.
The expedition was sponsored by the PNG Sustainable Development Programme.
The project's coordinator, Nathan Whitmore, says the expedition was carried out at three specific levels of the Hindenburg Wall and they are now preparing a formal report on the findings.
He says the species include a variety of orchids, carnivorous plants, butterflies, frogs and insects.
