The Papua New Guinea government has applied to have two remote mountain rainforests declared UNESCO World Heritage sites.
The Nakanai and Muller ranges are seen by conservationists as areas that need to be protected from logging and palm oil production.
Recently 200 new species were discovered there by the Papua New Guinea Institute of Biological Research, in partnership with Conservation International.
The co-director at the Institute, Banak Gamui, says the discoveries were made during two months of surveying in the rugged and little-explored areas.
"Hopefully this survey results will influence some of the decisions that are made at the top levels by the government and we hope this will lead us to real conservation on the ground."
