Eucalypt Action Group

Eucalypts have been a particular focus of farm foresters since the earliest days of our association over 50 years ago. The Eucalypt Action Group has a focus on eucalypts for hardwood solid timber end uses. We promote growing of eucalypts for the timbers natural durability, strength and hardness properties and decorative appearance. Eucalypt timber is suitable for on-farm uses such as posts and rails, along with structural applications such as exposed beams and decorative applications such as flooring and furniture.

Participate in our durable eucalypt trials!

During 2017 the Eucalyptus Action Group will be continuing with our stringybark eucalypt trials throughout New Zealand.

If you would like to participate please contact Angus Gordon (06 3881571) or Dean Satchell (09 4075525)

More about stringybarks >>

The EAG carries out its own research projects and is focussing on the stringybark group of species as being the most suitable for hardwood timber production in New Zealand. Breeding of durable species suitable for dryland areas of New Zealand is also an important area of research benefitting farm foresters. The Eucalypt Action Group has provided financial support for the Drylands Forestry Initiative (DFI) since its inception.


Reports

  • Report: Eucalyptus nitens, recovery and economics of processing 15 year old trees for solid timber May 2015
    Profitability of fast grown pruned and thinned Canterbury E. nitens was assessed for solid timber production from 15 year old trees.
  • Progress with hardwood forestryTreegrower, April 2013 The Sustainable Farming Fund-backed work of the Eucalyptus Action Group and farm foresters are producing promising results. Trees from research packs planted 10 years ago around New Zealand…
    If you want to be involved in the next generation of Eucalyptus Action Group stringybark trials, contact Angus Gordon 06 388 1571 angusg@xtra.co.nz or Dean Satchell 09 407 5525 dsatch@xtra.co.nz
  • Eucalyptus sawmilling report: Small-diameter sawmilling of cold-climate eucalypts June 2010
    This project addresses specific problems associated with grade-sawing younger, smaller-diameter plantation ash eucalypt logs in New Zealand. The results from the economic analysis of the stand used for the sawing study are sufficiently encouraging, with an internal rate of return well above that achieved for a typical radiata pine stand.
  • Improving siting recommendations for farm forestry eucalypts using GIS maps October 2013
    This project set out to collect growth and performance data on 16 Eucalyptus species that had been planted in trial sites across New Zealand during 2004 on 55 sites nationwide.
  • Stringybark eucalypt species trial report July 2007
    This project set out to test the survival and growth of a group of eucalypt species that have the potential for the production of naturally durable solid timber. The genesis of this project was the current and on going interest showed by farm forestry association members in these particular species, and also those people who see a potential niche market in the production of naturally durable posts for use in the viticulture industry. The focus was primarily on the stringybark  group of eucalypt species, planted in 2004 on 55 sites nationwide.
