Papua New Guinea's Eco-Forest forum says it's confident members of parliament will not support changes to the National Forest Board.
The prime minister, Sir Michael Somare, has told parliament he's tabling amendments which will do away with consulting landowners and provincial governments over logging operations.
But, the Forum says this will give the government more influence over the sector.
A Forum spokesman, Ken Mondiai, says many MPs and provincial governors told the forum after yesterday's parliamentary debate, that they won't support the amendments.
"It has not been properly debated, and they haven't been given the opportunity to get feedback from other sources, to verify the implications of it getting passed in its current format. So we are pretty confident that it will not get passed."
