- Thermal Modification of Douglas fir for Improved Durability
SWP-T047 - Access: unrestricted.
May 2018
Douglas fir has been thermally modified at two temperatures; 220°C and 230°C (each for 2 hours). These modifications are expected to improve the durability of the sapwood, while maintaining the… - Eucalyptus fastigata Veneer Stiffness
SWP-T048 - Access: unrestricted.
May 2018
UPT (ultrasonic propagation times) on its own is measuring both changes in density and changes in MoE, thus without an independent density measurement it is not possible to reliably determine… - Durable eucalypt forests – a multi-regional opportunity for investment in New Zealand drylands
SWP-T044 - Access: unrestricted.
May 2018
We believe our vision for the establishment of a durable eucalypt plantation estate is a unique opportunity to add value to New Zealand’s current forest industry. With our elite breeding… - Natural durability: Correlation between extractive content and fungal assay
SWP-T045 - Access: unrestricted.
May 2018
The main objective of this work was to validate if extractive content (EC) predicted by NIR spectroscopy correlated with mass-loss durability measurements. 7 year-old Eucalyptus bosistoana heartwood samples with known EC… - Programme description
SWP-T043 - Access: unrestricted.
March 2018
The Specialty Wood Products Research Partnership (SWP) is a partnership between Government and industry which aims to develop a high-value specialty wood products industry based on alternatives to radiata pine,… - LVL Trial: Pre-Harvest Stand Assessment
SWP-T042 - Access: unrestricted.
February 2018
Two trials located in Marlborough have been assessed as a potential source of peeler logs to carry out a peeler study. The trials are: E. bosistoana trial planted in 2003… - Durable eucalypt forests: A multi-regional opportunity for investment in NZ drylands
SWP-T041 - Access: unrestricted.
February 2018
This consultation paper is the first step in a process to develop the New Zealand Dryland Forests Initiative (NZDFI) regional strategic plan, focusing on the establishment of durable eucalypt forests… - Prediction of Extractive Content of Eucalyptus globoidea Heartwood Using Near Infrared Spectroscopy
SWP-T040 - Access: unrestricted.
November 2017
A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Forestry Science BForSc (Hons) Abstract Natural durability of wood is highly sought for a number of wood… - Performance of naturally durable eucalypt posts in Marlborough vineyards
SWP-T039 - Access: unrestricted.
October 2017
The area of vineyards in New Zealand is up from that reported in 2015, which was 35,463 ha. Posts in a vineyard average 500-600 per hectare so there are approximately… - Scion’s core funded experiments on thermal modification of Eucalyptus nitens.
SWP-T021 - Access: unrestricted.
August 2017
The objective of this work was to replicate successful lab scale thermal modifications of Eucalyptus nitens at a larger scale. Lab scale thermal modification has been shown to improve dimensional stability and… - Quantifying compounds in heartwood extractives of durable eucalypts
SWP-T037 - Access: unrestricted.
August 2017
It is known that the relative amounts of heartwood compounds differ between trees of the same species (Fries et al., 2000; Haupt et al., 2003; Partanen et al., 2011). This… - Development of the Douglas-fir Productivity Spatial Surface using the Process-based model 3-PG
SWP-T038 - Access: unrestricted.
August 2017
The objective of this report was to provide a New Zealand-wide productivity surface for Douglas-fir. This output addresses limitations of an earlier study of Douglas-fir spatial productivity that was based… - Expert Advisory Panel review of the SWP programme - 2017
SWP-T035 - Access: unrestricted.
July 2017
The project has many strengths and a few weaknesses (detailed in the body of the report). The main strengths include active industry/research collaborations, strong science, and a large team with… - Potential for Growing and Processing Durable Eucalypts in New Zealand
SWP-T036 - Access: unrestricted.
July 2017
In NZ there is considerable commercial interest in finding alternative forest species to radiata pine which (1) are naturally durable and do not require chemical preservative treatment for either in… - Pest management for durable eucalypts
SWP-T029 - Access: unrestricted.
June 2017
One of the more unexpected and important results from the phenology study summarised here, was that only one generation of P. charybdis was observed in each of the two years monitored. This…
