On Friday the state government announced the opening of a public consultation period on a proposal to rezone Future Potential Production Forest land as either conservation areas or regional reserves.

The land apart of the Western Tiers and already sits within the World Heritage Area.

Greens leader Cassy O'Connor said the decision to exclude the option for the area to become a national park from the consultation constituted a broken promise by the government.

Making the area a national park was a recommendation made by The United Nations Educational, Scientific and Cultural Organization after its reactive monitoring mission in 2015.

Australia's formal response to that mission says that both the Australian and Tasmanian governments supported all 20 recommendations made by UNESCO.

"Its taken six years for the Liberal government to take any action at all and then they come out with this mealy mouthed public consultation for lower protected status for forests which are of global significance and of enormous value to a safe climate," Ms O'Connor said.

"I didn't think the Gutwein government could be less Green than the Hodgman government but they are.

"We'd like to see every Tasmania who is proud of our parks and wants to see forests protected to make sure they let Minister Jaensch know that this area deserves national park status."

At the same press conference as Ms O'Conner Vica Bayley, who took part in the Tasmanian Forest Agreement Negotiations, said the government's decision was pathetic.

He said the government should and would be condemned by the international community.

"This just demonstrates the Gutwein governments fear and antipathy towards conservation." Mr Bayley said.

"This is an area that has recognised world heritage and national park values, it has been recommended to be made a national park by UNESCO itself and yet the best this government can do is conduct a consultation process over two lower conservation status options.

"Its pathetic and they really can do better. National parks are supposedly a brand and a cash cow winner for Tasmania. We know they are things that people come here to see and yet this government seems to have a fear and an absolute allergic reaction to declaring new national parks."

Parks Minister Roger Jaensch said the government was committed to reserving FPPF land in the world heritage area in line with classifications prescribed in Schedule 1 of the Nature Conservation Act 2002.

"The Tasmanian Government is committed to ensuring the public has a say in the type of reserves that will be established which is why we are inviting the public to comment on the proposal," he said.

"The Tasmanian Government will consider comments made, prior to tabling the draft proclamations in Parliament.

"The Government has no plans at this stage for other FPPF land to be moved into the reserve system."
