A series of expeditions by WWF scientists into previously unexplored areas of tropical rainforest in Papua New Guinea (PNG) have revealed new orchid species previously unknown to science.

Over the course of expeditions to PNG's Kikori region between 1998 and 2006, WWF teams collected some 300 species of orchids. Of those collected, eight have been confirmed as new species, while 20 more have yet to be verified as new.

Papua New Guinea already has more recorded orchid species than any other country in the world.

“The island of New Guinea is an incredible goldmine of orchids,” said Wayne Harris, a botanist from Queensland Herbarium in Australia and one of the world’s leading authorities on orchids. “There are over 3,000 known species found here with countless varieties undoubtedly yet to be discovered.”

WWF, together with the Kutubu Joint Venture Partnership, is working towards the long-term conservation of the Kikori region and the amazing diversity of plants and animals that it supports. The region is one of the last areas in PNG that includes such a variety of different forest habitats. Along with orchids and other plant-life, these remarkable forests are home to some of the country's most unique wildlife, such as birds of paradise, giant cassowaries and the enigmatic tree kangaroo.

The announcement of the discovery comes just a week ahead of the official launch of two new wildlife management areas, which will protect significant areas of rainforest where these orchids have been found.

WWF’s work in conserving the Kikori region is also vital to local communities. More than 20,000 people, from 12 different ethnic groups, live in the area and rely on the natural resources of its forests and streams for their subsistence livelihood.

“The discovery of such a large number of new orchid species is incredibly exciting,” said WWF Forest Ecologist Olo Gebia.

“The sad reality is that many of these plants, including those which may contain cures to some of the world’s most deadly diseases, may become extinct before they have even been discovered. This gives even greater urgency to ensuring the long-term conservation of this remarkable region.”
