A member of Tasmania's Legislative Council has conceded MLCs may not vote on the forest peace deal before Christmas.
The bill was passed by the Lower House last month, with the support of the Greens, and since then MLCs have been lobbied by groups on both sides of the bitter forest wars.
Upper House members are receiving State Government briefings this morning before starting to debate the legislation.
Independent MLC Ruth Forrest has told ABC Local Radio there would be no vote until information about funding for the deal has been provided.
She says it is possible members will sit between Christmas and the New Year.
"There's been some questions raised by people who've spoken to us that we need to actually clarify," she said.
"There's also the issues around funding to support the agreement so those things need to be considered and clarified as well, so there's still a number of outstanding issues that need to be addressed before we can, or before I believe, we can proceed with the bill."
