The Tasmanian Liberal Government is adamant it will not back down over plans to overturn a moratorium on logging in order to "rebuild the state's forest industry".

Plans to unlock about 400,000 hectares of previously reserved forest are set to be introduced into Parliament in the coming weeks.

Tasmania's Resources Minister Guy Barnett told ABC Radio Hobart the areas designated for harvesting were not "wilderness" and took a swipe at the Greens' opposition to the plan.

"It is a production forest … it is regrowth forest," he said.

To suggest, as the Greens would, that it's wilderness or needs further protection is a wonderful testament to our foresters to manage this land because it is primarily regrowth forest."

"None of that timber … will be able to be harvested unless it's done in accordance with the forest practices code, in accordance with all the environmental regulations that apply."

Mr Barnett said the plan would "save up to 700 jobs" by providing job security.

Tarkine, Bruny under threat, Bob Brown group says

But Jenny Weber from the Bob Brown Foundation said restarted logging would affect 100,000 hectares of the protected Tarkine Wilderness, which she said was a "vital stronghold for 65 protected species".

She said Mr Barnett's assertion the areas set to be harvested had been logged "over and over again is completely false".

"For many years now conservation groups have been campaigning for the forests of Bruny, Weilangta, the north-east highlands, the Tarkine and Ben Lomond," she said.

"These are all forests that will be directly impacted by the reopening of these forests for logging, rather than protecting them as future reserves.

"I'm calling on Minister Barnett to tell us what are these forests he's talking about."

The foundation released a map, which showed what it said were the areas the Government was "proposing to allow logging in high conservation value forests that were promised future protection under the abandoned Tasmanian Forest Agreement".

Terry Edwards, CEO of Forest Industries Association of Tasmania, told News Corporation his group had sought more information from the Government about the plan, to no avail.

"Many months ago we went to the Government and asked them to facilitate a very detailed assessment of these areas so everyone can be confident what it does contain in terms of conservation values and high quality wood," he said.

"The Government refused to do that and continue to refuse to do that, so we still don't know.

"We could be a lot more confident if we had that sort of information available to us."

Long history of antagonism

After it was elected in 2014, the Hodgman Liberal Government overturned the Tasmanian Forests Intergovernmental Agreement of 2011 — which became known as the "Peace Deal" — under protest from green groups.

The Tasmanian Forest Agreement Act 2013 was replaced by the Forestry (Rebuilding the Forest Industry) Act 2014, under which about 400,000 hectares of terrain were designated as future potential production forest for harvesting.

"For more than 30 years, environmentalists, with the help of Labor and the Greens, have progressively locked up hectare after hectare of productive forests, destroying businesses and jobs," Mr Hodgman said at the time.

In a move designed to calm dissent, the 2014 act laid out a moratorium on any logging before 2020.

However the Government's forestry business financial loss of 2016 led to Mr Barnett foreshadowing a dumping of the 2020 moratorium and opening up forests earlier than planned, sparking warnings by environmental groups of a return to decades-long so-called "forest wars" between environmentalists and pro-logging groups.
