Totara Industry Pilot Project (TIP)
Project Status: Completed
This was a collaborative project initiated by Tane’s Tree Trust and the other project partners which included Scion, Northland Inc. Te Taitokerau Maori Forestry Inc. and Te Uru Rākau. Peter Berg of Tane’s Tree Trust chaired the Steering Group. The project ran until mid-2020.
In Northland (and other regions), many farms have stands of native trees and scrub often dominated by naturally regenerating tōtara. In 2005 the Northland Tōtara Working Group (NTWG) formed to explore the potential to sustainably manage regenerating tōtara for timber production. Since then the group has conducted numerous studies on silviculture and timber use – all with encouraging results (see NTWG website pages).
They believe that an opportunity exists for sustainable timber production at a commercial scale to create economic returns for landowners and support business growth and employment within the Northland region, as well as bringing about the many desirable environmental enhancements associated with native forest cover.
The project harvested up to 300m3 of logs from sustainable forest management permits and plans on private land (involving 3 different farms). That timber was milled, dried and sold in order to understand the supply-chain and test the current market value. Research studies and trials captured useful data along the way. The results of the project indicated that a business case exists for a new regional industry – one based on the sustainable management of regenerating tōtara forests.
The timber was milled at Northpine, a commercial radiata sawmill located in Waipu. Timber grade recoveries from harvests were good. Accelerated kiln-drying studies on green timber were undertaken at Scion in Rotorua. The results of the kiln drying were compared with the traditional air-drying approach.
One kiln-charge (60m3) of 25mm boards was successfully dried from green, in four days, with little drying degrade. The 50mm and other-sized boards were taken to Scion in Rotorua for air, or slower kiln, drying at a smaller scale. It is anticipated that there will be options for commercial-scale kiln drying of 50mm boards in the future. The TIP timber was made available to end users for performance testing and appraisals.
Market demand is being tested and the TIP timber is available via. JSC Timbers. Contact Harry Garg on email jsctimber.co.nz or phone 09 412 2800.
Te Taitokerau Maori Forestry Incorporated have expressed an interest in progressing this initiative from here.
Other updates from the TIP project were included in the 2019 and 2020 NTWG Newsletters.
