Douglas-Fir

  • Speciality Species
The Douglas-fir resource is important in the southern South Island and colder parts of the central North Island.
At the start of the SWP, Douglas-fir growers identified that they wanted to increase productivity and wood quality, reduce disease risk, and diversify the product range of the species.
  • Implementing new breeding programme targets including new growth targets and resistance to Swiss Needle Cast
  • Development of new timber products, especially engineered wood
  • Testing new wood products, and developing earthquake-resilient construction systems using Douglas-fir cross-laminated timber (CLT)
  • developing a new GIS-based growth model for Douglas-fir and incorporating this into the industry’s Forecaster calculator tool
  • testing new engineered wood products – cross-laminated timber (CLT) and optimised engineered lumber (OELTM) – as a precursor to them attaining approval under the industry standards
  • developing CLT fasteners and connection systems, and proving these to be resilient to seismic shocks and simple to repair after damage
  • confirming that thermally modifying Douglas-fir sapwood and heartwood significantly improves durability
  • establishing new breeding targets: new selections focusing on form and productivity; trials evaluated and high-performing families identified.
