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 2019 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.
