Coast grey box
A slow-moderate growing Eucalyptus preferring 800+ mm of rainfall annually and well drained clay loam soils. A highly durable species which has led to an increase in establishment since 2017.

|
Least attractive features |
Slow-moderate growth rate and need to form prune. Sapwood susceptible to Lyctid borer. |
|
Most attractive features |
Strong, dense, hard and durable timber. |
|
Status as a plantation species in Gippsland |
High durability of timber has led to small but increasing areas being established since 2017. |
|
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.
