Western Australia is a state occupying the entire western third of the Australian continent. The species' scientific name marginata refers to the light-coloured vein on the border around its leaves. The tree and the wood are usually referred to by the Aboriginal name Jarrah. This is an article about a class of people as identified and defined within Australian law Because of the similar appearance of worked jarrah timber to the Honduras mahogany tree, jarrah was once called Swan River mahogany after the river system that runs through Perth. Honduras in Spanish, República de Honduras) is a democratic republic in Central America. The name mahogany is used when referring to numerous varieties of dark-colored wood originally the wood of the species Swietenia mahagoni, known as West Perth is the capital and largest city of the Australian state of Western Australia.

The tree grows up to 40 m high with a trunk up to 3 m in diameter, and has rough, greyish-brown, vertically grooved, fibrous bark which sheds in long flat strips. Bark, also known as periderm is the outermost layer of stems and Roots of Woody plants such as Trees It overlays the Wood and consists The leaves are often curved, 8-13 cm long and 1. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. 5-3 cm broad, shiny dark green above and paler below. The stalked flower buds appear in clusters of 7-11; each bud has a narrow, conical bud cap 5-9 mm long. A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also The flowers are white, 1-2 cm diameter, and bloom in spring and early summer. The fruits are spherical to barrel-shaped, and 9-16 mm long and broad. The term fruit has different meanings dependent on context and the term is not synonymous in Food preparation and Biology.

The bark of this eucalyptus is not shed in patches as it is with many others, but splits into fibrous strips. Eucalyptus (From Greek ευκάλυπτος meaning "well covered" is a diverse Genus of Trees (and a few shrubs the members of which Jarrah trees are also unusual in that they have a lignotuber, a large underground swelling which stores carbohydrates and allows young trees to regenerate after a fire. A lignotuber is a starchy swelling on underground stems or roots Because they are deep-rooted, as much as 40 m, jarrah are drought resistant and able to draw water from great depths during dry periods.

Ecology

Jarrah is an important element in its ecology, providing numerous habitats for animal life - especially birds and bees - while it is alive, and in the hollows that form as the heartwood decays. Ecology (from Greek grc οἶκος oikos, "house(hold" and grc -λογία -logia) is the scientific study of When it falls, it provides shelter to ground-dwellers such as the chuditch (Dasyurus geoffroii), a marsupial cat. The Western Quoll ( Dasyurus geoffroii) also known as the Chuditch or Western Native Cat, is a vulnerable Australian Dasyuromorph Marsupials are an Infraclass of Mammals characterized by a distinctive pouch (called the marsupium) in which females carry their young through

Jarrah has shown considerable adaptation to different ecologic zones - as in the Swan Coastal Plain and further north, and also to a different habitat of the lateritic Darling Scarp. The Swan Coastal Plain in Western Australia is the geographic feature that lies directly west of the Darling Scarp, and which contains the Swan River The Darling Scarp (previously known as the Darling Range or Darling Ranges) is a low Escarpment running north-south to the east of the [1]

Jarrah is very vulnerable to "dieback", the alga Phytophthora cinnamomi, which causes root-rot. Algae ( sing. alga are a large and diverse group of simple typically Autotrophic organisms ranging from Unicellular to Multicellular forms Phytophthora cinnamomi is a soil-borne Water mould that produces an infection which causes a condition in plants called "root rot" or "dieback" In large sections of the Darling Scarp there have been various measures to reduce the spread of dieback by washing down vehicles, and restricting access to areas of forest not yet infected. The Darling Scarp (previously known as the Darling Range or Darling Ranges) is a low Escarpment running north-south to the east of the

Uses

Jarrah flowers are used to make honey, but its wood is its main use. It is a heavy timber, with a specific gravity of 1. 1 when green. Its long, straight trunks of richly coloured and beautifully grained termite-resistant timber make it valuable for cabinet making, flooring, panelling and outdoor furniture. The finished timber has a deep rich reddish-brown colour and an attractive grain. When fresh, jarrah is quite workable but when seasoned it becomes so hard that conventional wood-working tools are useless. It is very durable, even in wet and weathered situations, making it a choice structural material for bridges, wharves, railway sleepers, ship building and telegraph poles. A railroad tie, cross tie, or railway sleeper is a rectangular object used as a base for Railroad tracks.

Jarrah wood is very similar to Karri wood, and as both trees are found in the south west of Australia, the two timbers are frequently confused. Karri ( Eucalyptus diversicolor) is a eucalypt which is native to the wetter regions of south west of Western Australia. They can be distinguished by cutting an unweathered splinter and burning it: karri burns completely to a white ash, whereas jarrah forms charcoal. Most of the best jarrah has been cut out of south Western Australia.

A large amount was exported to the United Kingdom, where it was cut into blocks and covered with asphalt for roads. One of the large exporters in the late nineteenth century was M. C. Davies who had mills in the Margaret River to Augusta region of the south west, and ports at Hamelin Bay and Flinders Bay. Maurice Coleman Davies ( 24 September 1835 &ndash 10 May 1913) was a Timber miller in the early History of Western Australia Flinders Bay is a bay and locality that is immediately south of the townsite of Augusta Western Australia, and close to the mouth of the Blackwood River and lies

The local poet 'Dryblower Murphy' even wrote a poem in the early twentieth century about the potential to extract alcohol from jarrah timber "Comeanavajarrah" [2] , suggesting that the resource was an endless one for exploitation. Edwin Greenslade Murphy (also known as Dryblower Murphy) ( 12 December 1866 – 9 March 1939) was an Australian Journalist Significantly most of the companies that exploited jarrah in the early twentieth century no longer exist.

Fortunately, jarrah is much more highly prized these days, and there is now an industry that recycles it from demolished houses. Even so, in 2004, old 4 inch by 2 inch (10 cm by 5 cm) recycled jarrah is routinely advertised in Perth papers for under AUD $1. "MMIV" redirects here For the Modest Mouse album see " Baron von Bullshit Rides Again " 50 per metre. Larger pieces of the timber were produced in the early history of the industry, from trees of great age, and these are also recovered from the demolition of older buildings.

Offcuts and millends, dead and fire affected jarrah also sell as firewood for those using wood for heating in Perth, and 1 tonne loads can now [Winter 2005] exceed AUD $160 per load. Jarrah tends to work well in slow combustion stoves and closed fires and generates a greater heat than most other available woods.

Jarrah is used in musical instrument making, as a top for the acoustic Stompbox and guitar inlays by Western Australian luthier Ellis Guitars. A stomp box or stompbox is a simple Percussion instrument consisting of a small wooden box placed under the foot which is tapped or stamped on rhythmically to Ellis Guitars is a company based in Perth, Western Australia producing handmade Acoustic guitars and acoustic stompboxes. It is also one of the main woods used in the manufacturing for the Brady Drum Company.
