The parliamentary inquiry into Tasmania's forest peace deal has been warned anti-forestry protests will continue even if supporting laws pass both houses.
Jenny Weber from the Huon Valley Environment Centre yesterday gave evidence to the Upper House Committee scrutinising legislation needed to protect half a million hectares of native forest from logging.
She says the environmental groups that negotiated the peace deal have abandoned their policies to end native forest logging.
"There are shortcomings in this agreement for the environment," she said.
Ms Weber says it means her organisation cannot rule out further protests.
"They didn't have a mandate to promise peace on our behalf."
The heads of the Australian Conservation Foundation and Wilderness Society had earlier told the inquiry that it was better to compromise than have no agreement at all.
The committee resumes hearings today.
