Establishment and silviculture

Follow our establishment guidelines for good establishment success.

E. globoidea may occasionally require form pruning, especially if unimproved stock is planted. Little clearwood pruning should be necessary if growing post and pole wood. For high quality sawlogs, some clearwood pruning at an early age may be necessary, but again this is less likely if improved XyloGene planting stock is used.

Read our form-pruning guidelines and watch some videos.

Pest and disease threats

E. globoidea  suffers less from insect and possum browse than some other eucalypt species.

Timing of flowering/potential to support bees

Summer/autumn flowering but with one winter record (Marlborough). Flowers regularly and yields good quantities of pollen and but not so much nectar. Good flavoured amber honey.

Growth models for E. globoidea

E. globoidea is the NZDFI species for which most growth models have been created.

Research by successful PhD candidate Serajis Selakin led to the development of some early growth models for E. globoidea and E. bosistoana

Hybrid growth models for E. globoidea and E. bosistoana (Salekin 2019)

More advanced modelling work, including modelling of tree taper and heartwood volume, was then completed by PhD candidate Daniel Boczniewicz.

More recently, carbon sequestration has been added to the model by Professor Euan Mason. The most recent version of the model is freely available.

Timber properties and markets

Two NZDFI PhD projects at the School of Forestry have focused on E. globoidea timber properties.

Durability

• Class 2 in-ground and above-ground durability (Australian Durability Standard AS 5604).
• In-ground life expectancy is 15-25 years.

Note:  Durability is a complex parameter; NZDFI’s research into heartwood formation will improve our understanding of factors determining durability.

Appearance

• Heartwood is dark brown/pink
• Sapwood pale brown/pink
• Moderately fine texture with straight grain

Applications

Structural uses, poles and posts, crossarms, railway sleepers, vineyard and fence posts. Also has potential as a flooring and furniture timber.

NZDFI anticipates E.globoidea will be highly suited as a component of high strength engineered wood products such as laminated veneer lumber (LVL) and cross laminated timber (CLT).

More information

Natural range

E. globoidea has a wide natural range through eastern New South Wales except the far north, and eastern Victoria except in areas where summers are too cool. It is found at altitudes of 0-1100 metres.

Cultivation in New Zealand

E. globoidea was selected for the NZDFI breeding programme based on its consistent performance across a range of sites.

There is considerable experience with E. globoidea on milder areas in New Zealand, where it has grown well for many decades.

Form is generally good although on fertile sites there may be a propensity to form double leaders.
