Shining gum
A very-fast growing Eucalyptus preferring 1200 mm+ of rainfall annually and deep (>2 m) gradational clay loam soils. Intolerant of prolonged drought, but is regarded as a mainstream plantation species for sites >300 m asl.

|
Botanical name |
Eucalyptus nitens |
Growth rate in preferred conditions |

Preferred Soil |
Deep >2 m gradational clay |
Prohibitive soil |
Shallow, waterlogged, duplex or uniform sands |
Poor drainage tolerance |
Low |
Dry site tolerance |
Very low |
Frost tolerance |
Very high |
Pest and disease problems: |
Autumn Gum Moth, Cerambycid/longicorn beetles. Target, Halo and Mycosphaerella leaf spot. |
Timber Characteristics1 |
|
Strength: seasoned timber only |
SD4-moderate |
Durability1: in ground | above ground |
4 | 3 |
Drying: green to 12% moisture content |
Drying needs much care because of collapse and surface checking. Shrinkage about 5% radial and 9% tangential. |
Main commercial products |
Pulpwood, joinery, veneer, general construction, flooring, furniture. |
Bushfire resistance2: measured by Bushfire Attack Level (BAL) |
BAL 12.5 and 19 – Door and window joinery only |
Least attractive features |
Drying difficulties. Intolerant of prolonged drought. Non-durable timber. Sapwood susceptible to Lyctid borer. |
Most attractive features |
Fast growth, great form, tolerates exposure, good pulp species, and sawlog/veneer potential. Light timber colour. Improved seed is available. |
Status as a plantation species in Gippsland |
Mainstream for sites at >300 m asl |
1 Based on Australian Standard: Timber Natural durability ratings. AS 5604-2005. Refer to Appendix for explanatory table. Where (?) applied, rating is based on field experience. 2 Naturally bushfire resisting timbers are those with inherent bushfire resisting properties. For more information refer to Australian Standard 3959:2018. |
Assumptions and notes:
- Sites considered for planting contain at least 1 metre of soil above an impeding layer (e.g. bedrock or layer impenetrable to roots.)
- Please note that most (if not all) eucalypts in Gippsland grow best on sheltered sites.
- Overall slow drying time across air and kiln dried schedules is recommended to minimise drying degrade. This is the best starting point for inexperienced operators.
