RESOURCES Minister Bryan Green has labelled protesters targeting timber company Ta Ann ``stupid''.

Members of the Huon Valley Environment Centre and Code Green yesterday mounted peaceful protests at two sites where they believe Forestry Tasmania is logging to supply Ta Ann.

Police attended the protest at Mawbanna, near Stanley, but made no arrests. One person will be summonsed for allegedly tampering with a vehicle.

``It's just so stupid by the conservationists to be protesting against Ta Ann when they are taking regrowth forest,'' Mr Green said yesterday.

``They're not taking old-growth forest and when we're right in the middle of a process where there's been an enormous amount of goodwill shown on all sides to try to resolve this debate, and they want to inflame it by closing down a legitimate operation in Tasmania.''

Late last year British firm International Plywood suspended buying from Ta Ann Tasmania, after being lobbied by conservationists.

Mr Green is yet to get a formal reply to his invitation to the company's management to visit Tasmania and reconsider the decision, but its receipt has been acknowledged.

Protesters are angry that the state and federal governments have allowed logging to continue within the 430,000 hectares meant to be placed in an interim reserve.

Mr Green's comments came a day after protesters disrupted the operation of Ta Ann's Huon mill for several hours. Both groups have vowed to continue action against Ta Ann until logging stops in the areas nominated for protection.

Code Green spokesman Jared Irwin said: ``It is business as usual in the forests, with old-growth and high conservation value forests tracts being lost despite being promised protection by the federal government last August.''
