Brown stringybark
A moderate to fast growing Eucalyptus preferring 900 mm+ of rainfall annually and gradational well drained soils. Not commonly trialled as a plantation species but early performance is promising with potential to be more frost hardy than Yellow stringybark.

Well drained soils in foothills |
Preferred Soil |
Gradational soils (well drained) with clay content |
Prohibitive soil |
Poorly drained soils |
Poor drainage tolerance |
Low to moderate |
Dry site tolerance |
Moderate |
Frost tolerance |
High |
Pest and disease problems: |
Susceptibility to ringbarking by cattle. High susceptibility to Phytophthora cinnamomi. |
Timber Characteristics1 |
|
Strength: seasoned timber only |
SD3-moderate/high |
Durability1: in ground | above ground |
3 | 2 |
Drying: green to 12% moisture content |
Care needed to minimise degrade. Considerable collapse can occur. Shrinkage about 5.1% radial and 10.4% tangential. Reconditioning commonly required. |
Main commercial products |
General construction, notably building framework, and firewood. |
Bushfire resistance2: measured by Bushfire Attack Level (BAL) |
BAL 12.5 and 19 – All AS3959 required applications |
Least attractive features |
No improved seed sources available. Ringbarking by cattle. Phytophthora cinnamomi susceptibility. |
Most attractive features |
Sapwood resistant to Lyctid borer attack. Not difficult to work. |
Status as a plantation species in Gippsland |
Not a commonly trialled plantation species. Early performance is promising. Potentially more frost hardy and tolerant of poor drainage than Yellow stringybark. |
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.
