SWP-T073 - Access: unrestricted.
May 2019
The Specialty Wood Products Research Partnership wish to know where there are opportunities to develop processing of Douglas-fir, Cypress and Eucalyptus species (nitens and fastigata). A previous report covers the… - Dimensional Stability of Specialty Species (interim report)
SWP-T074 - Access: unrestricted.
May 2019
Dimensional changes caused by changes in wood moisture content (dimensional stability) can have a large impact on how the wood performs in service. Poor dimensional stability can lead to cracking,… - Molecular deformation of wood and cellulose studied by near infrared and Raman spectroscopy
SWP-T071 - Access: Executive.
March 2019
Eucalyptus can be alternative plantation species to radiata pine for New Zealand. One major problem preventing eucalyptus wood from high-value uses is its high growth-stress level, which causes problems in… - Heartwood in Eucalyptus bosistoana (2009 plantings)
SWP-T072 - Access: unrestricted.
March 2019
The ultimate goal of the NZDFI breeding programme is to exploit variation in quantity and quality of extractive content to identify superior families in terms of heartwood content and quality.… - Hybrid growth models for Eucalyptus globoidea and E. bosistoana: Explaining within and between site variability
SWP-T070 - Access: unrestricted.
February 2019
Plantation forests play a major role in satisfying many forestry needs such as demand for wood and different ecosystem services, which are projected to increase in the future. In New… - Extending durable eucalypt species research by establishing new demonstration trials in 2018
SWP-T069 - Access: unrestricted.
December 2018
While the NZDFI genetic improvement programme is concentrating efforts and resources on a few promising candidates, these and a broader list of species of interest are being evaluated in demonstration… - Optimising new PSP locations for durable eucalypts
SWP-T065 - Access: unrestricted.
September 2018
As part of an effort to develop a forest industry based on durable hardwood eucalypts in New Zealand, a network of sample plots for numerous species has been established throughout… - The decay resistance of some wood species used as framing - Progress report on the condition of samples
SWP-T064 - Access: Executive. This SWP report shall at all times be kept confidential and not directly or indirectly be made available to anyone who is not an SWP member.
September 2018
Sets of framing samples were exposed in high humidity conditions of 85-90% relative humidity and 25 – 27°C. The species included in this test were: untreated Cupressus lusitanica untreated Douglas-fir… - The decay resistance of six Eucalyptus species in stake and stakelet trials after two years exposure

September 2018
Durability stakes and stakelets were prepared from six different durable Eucalyptus species, (Eucalyptus bosistoana, Eucalyptus quadrangulata, Eucalyptus pilularis, Eucalyptus sphaerocarpa, Eucalyptus globoidea, Eucalyptus muelleriana.) For each species timber had been… - Economic impact of eucalyptus tortoise beetle (Paropsis charybdis) in New Zealand
SWP-T067 - Access: unrestricted.
August 2018
A number of tree species in the genus Eucalyptus are grown in New Zealand on a small scale. However, the economic value of this resource is not known. The economic impact of… - Supercritical CO2 dewatering of E. nitens. Results of Scion’s core funded experiments
SWP-T062 - Access: unrestricted.
August 2018
