Pest and disease problems: |
Susceptibility to ringbarking by cattle. < 3 months after planting - Light Brown Apple moth. 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 |
Dries readily, but care needed to minimise checking and end splitting, some collapse can occur, but is recoverable through reconditioning. Shrinkage about 4.5% radial and 7.5% tangential. |
Main commercial products |
Versatile species with many uses. Joinery, panelling, veneers, light & heavy construction, cladding, internal and external flooring, decking, outdoor furniture, sleepers, posts and poles, firewood. |
Bushfire resistance2: measured by Bushfire Attack Level (BAL) |
BAL 12.5 and 19 – All AS3959 required applications |
Least attractive features |
Ring barking by cattle. Phytophthora cinnamomic susceptibility. |
Most attractive features |
Good drying properties. Sapwood resistant to Lyctid borer, Stability of green timber when sawn. Versatile range of uses. Regarded as the best of the Stringybark timbers. |
Status as a plantation species in Gippsland |
Mainstream durable sawlog species. |
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.
