The Paulownia harvesting company, which established a plantation at Forbes last year, begun its first harvest of investor timber last week at Kingaroy - one of its seven plantations.

The harvest marks a milestone in the company's development and coincides with surging investor interest in timber plantation projects, the company's chief executive officer, Ian Sandeman said.

Mr Sandeman said it would provide a platform for the company's continued growth.

"I'm very happy to say that QPFL has not only reached its first commercial harvest, but the timber has been presold at a better price than we had stated in our current product disclosure statement," Mr Sandeman said.

"That's very good news for our investors and it comes at a very good time for QPFL, as investors are showing renewed interest in agribusiness ventures."

Mr Sandeman said leading agribusiness researchers have noted exceptional growth in Australian agribusiness projects over the last 12 months, on the back of increased investor confidence.

He said Paulownia is already known to have high value applications for timber blinds, marine board and other products manufactured with jointed board.

The company expects to begin its next round of major plantings next month at the Forbes plantation, where the company has recently invested in extensive irrigation work as a protection against drought.
