New figures indicate farmers could be moving to clear trees from their properties ahead of new, tougher tree-clearing laws due before Queensland Parliament later this year.

The ABC can reveal investigations are underway into 86 instances of "unexplained clearing" since the legislation was introduced in March.

Satellite images show nearly 1,000 hectares of bush were cleared from one property alone.

"Some of this probably is panic clearing," Wilderness Society spokesman Tim Seelig said.

"Some of it is simply clearing that shouldn't be done.

"The Government is doing the right thing here and getting straight on to it."

The 86 cases were picked up from satellite imagery.

The State Government has also received an average of 16 illegal clearing complaints a month in the past year.

Opposition spokesman Andrew Cripps said farmers would not clear bush unnecessarily.

"Those landowners will be very concerned that the opportunities for expanding their farm businesses that were afforded them under the previous Liberal National Party government were going to be taken away," he said.

Farmers meet in Rockhampton to discuss new laws

Farmers worried about the new tougher tree-clearing regime met in Rockhampton today, raising concerns about issues like the proposed reverse onus of proof.

"The Queensland Government has created this culture of fear, because of this unnecessary legislation," Mr Cripps said.

But Environment Minister Steven Miles said it was too soon to assume panic clearing was underway.

"We need to let the investigators get out there and find out exactly what's happened," he said.

The proposed new laws will be retrospective, but landholders will not necessarily be punished if investigators find they had made a mistake.

"Nobody has anything to fear here if they aren't doing anything wrong," Mr Miles said.

A parliamentary committee reviewing the new tree-clearing laws is due to deliver its report next week, with the legislation due for debate in August.
