Mr Best, a Labor member for Braddon, said today the costs to businesses of the anti-forestry protests was growing.

He said workers from Maxfield Drilling had been prevented from entering a gravel quarry being used to source road material for five hours on Wednesday and yesterday a protestor chained herself to a drill rig.

Estimates of the cost of policing the protests have been put at more than $100,000.

``This stupidity has gone far enough,'' Mr Best said.

``No one is safe from the illegal and dangerous antics of these extremists and it is costing businesses and taxpayers tens of thousands of dollars.

``Businesses like Maxfield Drilling should not have to wear the costs and their employees should not be subjected to this sort of intimidation.''

Mr Best said the general public was fast losing patience with protestors and renewed calls for Greens Leader Nick McKim to intervene.

``The damage they are doing to businesses extends around Tasmania and its really starting to hit home with workers from the North-West Coast.''

Meanwhile the Wilderness Society is inviting the community to help provide solutions to the forestry debate through a series of `community conversations'.

``I firmly believe a solution to the current stalemate is possible and the community has a critical role to play in helping forge a positive path forward,'' spokesman Vica Bayley said.

``A logging industry representative and Premier David Bartlett will be invited to speak at each event, sharing the stage with the Wilderness Society and fielding questions from the floor.

``The public will then be given an opportunity to give their number one idea for a way forward for Tasmania to resolve the forest debate and begin to heal the community.''

Mr Bayley said the suggestions would be delivered to the Premier when parliament resumes.
