She has called on Premier and Climate Change Minister Peter Gutwein to "rethink logging of native forests".

However, Resources Minister Guy Barnett accused the Greens of scaring Tasmanians.

Ms O'Connor said in a climate emergency it was unjustifiable.

"The Tarkine is being logged apparently so that some luxury building in Hobart can have blackheart sassafras on its ceiling," she said.

"It damages the Tarkine's natural and cultural values, releases carbon into the atmosphere and the scientists tell us that it increases fire risk.

"The more you log this place, the more you increase fire risk in a time when the landscape is already drying out."

However, Mr Barnett dismissed the fire risk.

"Claims by the Greens that a 60 tree specialty-timber harvest from an area of our permanent timber production forests will increase bushfire risk is hypocritical and disingenuous," Mr Barnett said.

"The Greens previously supported selective harvesting in this area, now they want to shift the goal posts to scare Tasmanians.

"The Tasmanian majority Liberal Government is committed to supporting our sustainable forestry industry and supporting the production of high-quality, specialty timber products that Tasmania is renowned for.''

Meanwhile, the Bob Brown Foundation said it had received a letter from Sustainable Timber Tasmania on Monday to say that logging was not going to continue in a Tarkine coupe where 60 activists have established an occupation.

"Our occupation of these forests has successfully forced the loggers to abandon further destruction of these remarkable ancient forests and we will stay in these ancient forests until the last machine is out," Dr Lisa Searle said.

The foundation said less than five hectares of a 28 hectare coupe had been logged.
