Identify Native Hardwoods
A comprehensive guide to identifying West Australian hardwood species for recovery and high-value timber use
Key Species
Identifying West Australian hardwoods correctly is the first step in successful timber recovery. Each species possesses unique characteristics in bark texture, grain density, and colour that determine its best end-use for structural or furniture applications.
Jarrah
Jarrah is distinguished by its rich reddish-brown hues and deep, interlocking grain. In the field, look for fibrous, stringy bark that remains relatively tight to the trunk. It is highly valued for both its extreme durability and its aesthetic appeal in reclaimed flooring and outdoor structures.
Marri
Marri, or Red Gum, is easily identified by its light honey-to-blonde colouring and prominent gum veins (kino). The bark is rough, grey, and tessellated (tile-like). While historically seen as a secondary timber, its unique character grain makes it a favourite for modern bespoke furniture.
Tuart
Tuart is one of the world's strongest timbers, with a pale yellow-white appearance and an exceptionally tight grain. Identifying it in log form requires looking for its distinctive boxy, fine-textured bark. Because of its density, Tuart recovery requires specialised milling expertise.
Karri
Karri logs are often recognised by their massive scale and smoother, shedding bark that reveals patches of white and orange-grey. The timber is pinkish-red and has a characteristically long, straight grain structure, making it ideal for high-span structural beams and heavy-duty flooring.
Recovery Criteria
- Log Length: Minimum of 2 metres preferred consistently for structural milling.
- Diameter: Logs should exceed 300mm across to ensure high-quality heartwood recovery.
- Condition: Limited heart decay; the log must have substantial structural integrity.
- Species: Native WA hardwoods like Jarrah, Marri, Blackbutt, Karri, and Tuart.
- Accessibility: The log must be located in an area that is accessible on foot with a 6x2m clear area.
