The Prime Minister is likely to encounter more conflict over Tasmania's forests when she visits the state this weekend.

Julia Gillard arrives in Tasmania today.

Her visit follows yesterday's signing of the latest forests peace deal agreement between the state and federal governments which gives back some land for logging.

The interim agreement will give protection to about 428,000 hectares of high conservation value forest.

It allows just under 2,000 hectares to be harvested by Forestry Tasmania to meet existing contracts over the next six months.

The forest peace deal allows for compensation to industry if not enough wood can be supplied to meet contractual obligations.

The State Government has chosen not to use that option.

Acting Premier Bryan Green says the Government does not want to shut the industry down.

The conservation agreement will provide interim protection for the forests until the areas designated for permanent protection are determined.

Professor Jonathan West and the independent verification group are expected to complete their work next month and legislation is due before Parliament by the end of June.

Condemned

The Greens have condemned the interim agreement.

Senator Bob Brown says it will allow for the destruction of an area of forest the size of 1,000 Melbourne Cricket Grounds.

"You keep killing the heart of what it is to be a wild ecosystem," he said.

"The coops that are on the death list from (Federal Environment Minister) Tony Burke and Bryan Green include areas in the Weld Valley and the Picton and Huon Counsel River in Central Tasmania, a magnificent region." he said.

The Prime Minister is due in Hobart this weekend for discussions with the State Government over the forest deal.

Julia Gillard will also meet independent MP Andrew Wilkie over poker machine laws.
