A specialty timber merchant in Tasmania believes there will be no problem with supply under the forest peace deal.

Bob MacMillan has been salvaging speciality timber for decades.

With many international tonewoods now endangered, his wood is in demand by international guitar makers like Fender and Martin.

Mr MacMillan says with proper selective harvesting the resource will last for generations.

"And I tell people this and they say well I'm not going to be here in a couple of hundred years and I say, so what, the timber's going to be here forever if it's used correctly and managed correctly," he said.
