The Federal Regional Development Minister insists a report on the job impacts of Tasmania's forestry peace deal is credible, despite one of its authors working in the industry.
The study into the socio-economic effects of the deal shows it would save at least 500 jobs in the sector.
It was commissioned by the Federal Government when signatories signed the forestry peace deal and has been released by the Minister Simon Crean in Hobart.
The document compares two scenarios: the first is under the forestry peace deal; the second is without a peace deal with logging occurring outside the 570,000 hectares of forest under contention.
If no deal is secured, the report found more than 1,900 direct and indirect jobs would be lost, including 600 forestry jobs.
But with a peace agreement, only 142 forestry jobs would be lost and 405 direct and indirect positions.
The Minister says it is clear there would be bigger impact on job losses if the deal is not done.
"It makes the compelling point that in the last five years without any agreement and stats quo if you like, the number of jobs in the industry have halved already because the market is rejecting product that isn't from a sustainable resource," he said.
Mr Crean says the report should not be undermined by the fact that one of the co-authors is a Forestry Tasmania director, Bob Smith.
Mr Smith's conflict of interest is declared on the Mr Crean says the findings add pressure on Tasmania's Upper House to pass the forest peace deal legislation.
A copy of the study was sent to Legislative Councillors last night.
"This is a pretty dramatic set of figures, [I'm] very happy to talk to the Legislative Council anytime they want as I have done," he said.
"But they've been taking submissions, they knew this was coming and they wanted to make judgements about this when the report was out, they wanted to consider it, so here it is." The Tasmanian Government has welcomed the report.
Premier Lara Giddings says it shows 1,200 forestry jobs have been lost since 2006 and the industry cannot afford to continue without a deal.
"What this report shows is without the Tasmanian Forest Agreement we will be far worse off with more jobs lost than with the Tasmanian Forest Agreement that restructures and industry that is in fast decline, that gives an industry hope that gives and industry a future," the Premier said.
Ms Giddings wants Upper House MPs to consider the report.
"The heavy responsibility is now on the Upper House to pass that legislation when we get back into Parliament in March." "Any further delays will see more jobs lost in the forest industry."
