Premier Peter Gutwein has conceded findings from a cultural assessment of the government's plan to reopen four-wheel drive tracks in the Tarkine make it "extraordinarily difficult" to do so.
Mr Gutwein on Friday said the report would be considered by cabinet over the coming weeks and a decision on the plan would be made then.
"It expect that it would be extraordinarily difficult to see these tracks opened," he said.

"The report is quite clear in that regard.
"We'll act on the evidence that's provided. There could be next steps, but I think that would be a very challenging pathway to take."
The tracks were closed in 2012 to protect indigenous heritage sites.
Aboriginal Land Council of Tasmania chairman Michael Mansell called on the government to move on from the 2014 election pledge in light of renewed discussions about reconciliation.
"The report should finally put a stop to this crazy scheme that was made to get a few hundred votes in Smithton at the expense of ancient irreplaceable Aboriginal heritage," he said.
Mr Mansell said the report noted consent for the plan had not been obtained from the Aboriginal community which meant it ran contrary to state and Commonwealth heritage legislation, policies and guidelines.
Tasmanian Aboriginal Centre heritage officer Sharnie Read said there was no Aboriginal representation on the Arthur-Pieman Conservation Area management committee.
"We have been treated like any other member of the public rather than owners of our own land and heritage," she said.
"That has to change if our community is to be confident in the good will of this Tasmanian Government as we head down the path of reconciliation."

Acting Greens leader Rosalie Woodruff said the government needed to immediately rule out reopening the tracks.
"Being non-committal about the need to protect tens of thousands of years of Aboriginal heritage is not good enough," she said.
"The Liberals must also make a commitment that any proposal for alternative 4WD tracks does not compromise cultural or environmental values elsewhere."
The Circular Head Council in a statement said while the Arthur-Pieman Conservation Area was managed by the state government, it was within the Circular Head municipality.
"Council are therefore an important stakeholder," it said.
"As such, council will consider the report in due course, but are yet to determine a collective position on the report."
