Where is jarrah sourced




















Their long, straight trunks, can grow up to 40 metres tall and 2 metres in diameter, creating beautifully coloured and grained timbers. The bark is rough with a fibrous texture, and covers the entire trunk and smallest branches.

The trees do not germinate from seed, but from lignatubers, large underground swellings that store energy and nutrients, allowing young trees to regenerate after bushfires. Jarrah timbers reflect the hues of the Western Australian landscape. The heartwood varies in colour from rich reds to browns, while sapwood ranges from a pale yellow to orange.

The texture of the timber is moderately coarse and even-textured grain, although some interlocked, wavy grain may feature, creating interesting fiddle-back figure. This makes it an appealing architectural and design material. Jarrah's natural properties include a high resistance to weather, rot, termites and even marine borers, making it valuable for a range of outdoors uses.

Its density also makes it fire resistant. It can be used in wharf and bridge construction, railway sleepers, cross arms, poles and piles. Construction applications include general house framing, flooring, linings, joinery and fencing. Jarrah's decorative qualities make it prized for use in furniture, turnery, joinery and parquetry. Jarrah makes a versatile and aesthetically pleasing decking board based on its natural durability and bushfire resistance properties BAL Modulus of Elasticity - Unseasoned:.

Maximum Crushing Strength - Seasoned:. Jarrah is renowned for its rich red colours that deepen over time. The heartwood ranges from deep browns to burgundy hues. Jarrah sapwood exhibits shades from pale yellow to pink-orange.

The timber displays a moderately coarse and even textured grain. The occasional incidence of wavy and interlocking grain produces some samples with a sought after fiddle-back figure.

Jarrah has a history of use in engineering applications such as wharf and bridge construction, railway sleepers, cross-arms, piles, and for road bases. Its structural applications include posts and poles, framing, flooring, lining, decking and cladding. A highly versatile timber, jarrah can also be used for woodturning, making it useful in the manufacture of high quality indoor furniture and weather resistant outdoor furniture that stands the test of time.

The wood is also prized by luthiers for creating guitar and banjo necks. The heartwood of this tree is most prized for its deep red to burgundy color, which occasionally shows black streaks. The wood can darken over time with exposure to air so that it resembles mahogany.

The sapwood is paler, usually pinkish-red. Jarrah grows only in southwestern Australia. According to Woodworkers Source, jarrah is the most widely harvested species of the Eucalyptus. And because jarrah trees have a relatively limited distribution area -- about a mile band around the coast of southwestern Australia -- old-growth sources are dwindling all the time, although some environmentally responsible or sustainable sources do exist.

Jarrah trees are large, growing from to feet tall and over 6 feet in diameter. The wood is dense and resistant to insect damage and decay, although it is susceptible to the root rot fungus.

The wood appears in either straight or irregular grain patterns, and sometimes exhibits wavy or fiddleback patterns. Sometimes you might see dried sap pockets or gum veins. On the Janka Hardness Scale, it ranks as harder than oak but not as hard as teak or mahogany. The sapwood is paler, usually pinkish-red. Jarrah grows only in southwestern Australia. New Jarrah is a sustainable, renewable resource , exclusively harvested from regrowth forests in WA.

All native forests harvested in WA are regenerated or replanted each year. Record yourself saying 'jarrah' in full sentences, then watch yourself and listen. You'll be able to mark your mistakes quite easily. Australian Oak is a mixture of two Eucalypt species. It ranges in colour from pale pink to brown straw. It is straight, open and even grained with a uniform texture, usually all quartersawn for stability with excellent staining properties. Victorian ash carries independent PEFC certification.

The antimicrobial activity of Jarrah honey is derived via natural enzymes in the honey. While the antimicrobial and healing effects of honey have been known for thousands of years, Jarrah honey has become increasingly popular for its medicinal properties , low glucose levels and a high antimicrobial activity. The jarrah tree can live as long as years. The jarrah tree usually grows in gravely soil, but occasionally it is found in sand or loam. The jarrah tree has widespread distribution in the dry Australian Savannah.

Counts of growth rings indicate that the very large jarrah and marri trees in the south west forests of Western Australia are unlikely to be older than years. Balsam poplar is a hardwood native to Asia and North America, and small quantities are imported into Australia. It is used for match splints, plywood, artificial limbs, brake blocks, wood wool and boxes. Jarrah is also naturally weather, rot, termite and marine borer resistant making it a highly durable timber for outdoor purposes, however the sapwood of the timber is Lyctid borer susceptible, so the sapwood present in decking may sometimes be treated.

Australian Buloke — 5, IBF. An ironwood tree that is native to Australia, this wood comes from a species of tree occurring across most of Eastern and Southern Australia. Known as the hardest wood in the world, this particular type has a Janka hardness of 5, lbf.
