That's the finding from a new report by the NGO, Forest Trends.
The group tracked the flow of conservation finance under the UN conservation programme known as REDD+ between 2009 and 2014.
It identified US$45.3 million in total finance directed to REDD+ programmes in PNG, over half of which came from individual donor countries, with Japan the largest donor by far.
A senior associate in the REDD+ forest conservation finance tracking initiative, Brian Schaap said not a lot of resources are being deployed to conserve PNG's huge forests.
