Forestry Tasmania last night released a 50-page report titled Forestry Management in Tasmania: The Truth on the same day that timber processor Ta Ann put out a glossy information brochure on its operations.

Both companies said they were responding to misinformation from environment groups.

About 50 people gathered outside Ta Ann's Hobart headquarters with pro-company placards that read ``We need job security'' and ``Our futures, our jobs'' and faced off with up to 30 anti-company protesters who showed up soon after.

Ta Ann operations manager Paul Woolley is urging the state and federal governments to speed up the process behind a $276 million forests deal that will decide what forests are protected and what will be used to supply industry.

``We support the IGA (intergovernmental agreement) process and I suppose what we're asking is for it to be quickly finalised, so we can get on with our business. Our business is peeling and producing high-quality flooring,'' Mr Woolley said.

``The longer this process goes on, it's like a rot, the less certainty there is (for the industry) and the more nervous . . . our customers get.''

Jane Calvert, of the Construction, Forestry, Mining and Energy Union, said the 160 workers employed by Ta Ann were fed up with protests at their worksites, which put everyone's safety at risk.

But members of the Huon Valley Environment Centre sid they were determined to continue such action.

Spokeswoman Jenny Weber said wood supply required by Ta Ann was the main reason that Forestry Tasmania continued to log within 430,000 hectares of native forests labelled by green groups as having high conservation values.

Forestry Tasmania managing director Bob Gordon said it was regrettable that the state-owned company had to spend resources on countering misinformation.

Tasmanian Greens leader Nick McKim said the public relations material used terms like ``regrowth timber'' to mislead the public.

``This is just another attempt by Ta Ann to green-wash their operations, because the fact is that they are being supplied from within the 430,000 hectares of high conservation value forest which the IGA said should now be protected,'' Mr McKim said.
