eucalyptus camaldulensis wood

Rabiul Alam1 1 Forestry and Wood … Changes in its habitat, however, could be detrimental not just for the tree, but also for species that depend on the tree for their own survival. Red gum is so named for its brilliant red wood, which can range from a light pink through to almost black, depending on the age and weathering. Wilson,[23] who examined the management of river red gums in NSW, suggests shelter is provided for fish in rivers and streams by fallen branches from the river red gum. The trees not only rely on rainfall but also on regular flooding, since flooding recharges the sub-soil with water. Triangular valves in the fruit will open, dispersing yellow, cuboid seeds. (Though these species are currently not under threat.) These changes include grazing, and water regulation for irrigation purposes. The best way to split the wood is about 5-7 days after it has been cut. Its leaves have appeared on Australian stamps[35] and is widely recognised due to its widespread range. globulus hybrids were made with the objective of producing trees that have commercial yields of wood or pulp when grown on saline land (Meddings et al. These filaments will extend to encircle the receptacle during flowering. Proceeding of an international workshop. To test this idea and to establish the relationships between temperature, hydraulic conductivity, wood anatomy and wood density, we grew Eucalyptus camaldulensis (Dehn.) Nazrul Islam1,2, Khandkar-Siddikur Rahman1* and Md. This tree can be found along water ways and other wetlands. The literature indicates that for E. camaldulensis and E. globulus up to 5.5 y old there is little 1(9), 54-58, September (2012) Res.J.Recent Sci. Marketing multipurpose tree products in Asia. The global weed compendium[30] lists E. camaldulensis as a weed in Portugal, Canary Islands, South Africa, Spain, Bangladesh, the United States, Ecuador, the Galapagos and other countries. Eucalyptus camaldulensis x E. globulus subsp. longirostris. 123 Wood Sci Technol (2012) 46:143–155 147 As it was shown by Hamilton et al. Small cracks will appear in the wood but overall it will still be wet. In the Murray-Darling Basin, such floods are now rare due to river regulation for irrigation, and as a result, 75% of River red gums in the lower Murray are stressed, dead or dying. From Australia Forestry and Timber Bureau, Illustrations of the buds and fruits of eucalyptus species , 4th ed., 1962 Buds in sevens, with conical opercula , can always be found, though sometimes there are as many as 11. It makes an excellent bonsai and will readily regrow both from the base and from epicormic buds. (This is a monthly update, and your email will be kept private.). and Simul (Bombax ceiba L.) Veneers Nazmul Alam D.M.1, Md. Thus the displacement of the Cadell Fault 25,000 years BP led directly to the formation of the Barmah river red gum forests. trees growing in Thailand. The Cazneaux Tree, near Wilpena Pound in Flinders Ranges National Park, "The Queen's Tree", Kings Park, Perth, WA, 10.1002/(SICI)1099-1646(199603)12:2/3<223::AID-RRR391>3.0.CO;2-#, Center for New Crops & Plant Products, Purdue University, https://en.wikipedia.org/w/index.php?title=Eucalyptus_camaldulensis&oldid=995913570, All Wikipedia articles written in Australian English, Articles with unsourced statements from September 2018, Creative Commons Attribution-ShareAlike License. The grain begins to twist and splitting a dry piece of the wood is not easy. [22][23], The species can be found along the banks of watercourses, as well as the floodplains of those watercourses. Like many stands of river red gum, the Barmah-Millewa has been drastically altered by over 100 years of timber harvesting. This is especially important to the ecology in areas of low nutrients. [23], An image of The Old Gum Tree was engraved for a stamp in 1936 to commemorate the centenary of foundation of South Australia. Regulation causes flooding to be decreased during the winter and spring months, and water more consistently flows during the summer and autumn months. Due to the proximity to these watercourses, river red gum is subject to regular flooding in its natural habitat. It quickly toughens up and can withstand drought even whilst in forestry tubes. This created a complex series of events. The flower buds are arranged in groups of seven, nine or sometimes eleven, in leaf axils on a peduncle 5–28 mm (0.20–1.10 in) long, the individual flowers on pedicels 2–10 mm (0.079–0.394 in) long. To promote solid wood production, the diameter at breast height, height, stress-wave velocity, surface-released strain, basic density and compressive strength parallel to the grain were measured for 10 half-sib families of 12-year-old Eucalyptus camaldulensis Dehnh. Eucalyptus camaldulensis Dehnh. It is a popular timber for wood turners, particularly if old and well-seasoned. Based on the results, growth rates, correlations among measured properties, radial and … The speed of growth of the tree makes it a useful plantation timber. Hollows start to form at around 120–180 years of age, creating habitat for many wildlife species, including a range of breeding and roosting animals such as bats, carpet pythons, and birds. 1(9), 54-58, September (2012) Res.J.Recent Sci. Eucalyptus is prone to cellular collapse so distortion in drying is quite common as well as surface checking. 2001, 2003). Proceeding of an international workshop. Eucalyptus camaldulensis is a common and widespread tree along watercourses over much of mainland Australia. Eucalyptus camaldulensis is an evergreen Tree growing to 30 m (98ft) by 20 m (65ft) at a fast rate. E. camaldulensis wood burns well and makes a good fuel, used in several countries such as Brazil (Jacobs, 1981; Eldridge et al., 1993) for the large-scale production of charcoal for the iron and steel industries, and its dense wood and coppicing ability make it an excellent species for fuelwood production. E. camaldulensis is important in supporting the ecology of its habitat through providing food, and shelter for breeding. This has resulted in a large population and range for the species, and so it is not considered endangered. Eucalyptus conjures images of Australia, whose old-growth forests primarily consist of this large, strong tree. The male parts of the flower consist of the stamen, a slender filament, and the anther, two pollen sacs located at the top of the stamen. The primary result of the Cadell Fault however is that the west-flowing water of the Murray River strikes the north-south running fault and diverts both north and south around the fault in the two main channels (Edwards and ancestral Goulburn) as well as a fan of small streams, and regularly floods a large amount of low-lying country in the area. [30] The species, while native to parts of Western Australia, has become naturalised via garden escapees and introduction as a restoration plant; they are the subject of weed management programs. Wood chips of . The cracks will help you "read" the wood. Culturally, the species is an iconic part of Australia. Red Gum(Eucalyptus camaldulensis) Red Gum - Commonly known as sap gum or sweet gum, red gum grows in Southeast United States. There are often loose, rough slabs of bark near the base. 1985. Introduction. The bark is smooth white or cream-coloured with patches of yellow, pink or brown. Are Rosewoods (and Bubinga) really banned by CITES? The literature indicates that for E. camaldulensis and E. globulus up to 5.5 y old there is little The superb parrot, a threatened species, is amongst the bird species that nest in the river red gum.[29]. "As firewood, the timber from Eucalyptus camaldulensis has few equals. Results and discussion Eucalyptus camaldulensis properties Density and fiber length are important parameters used by the pulping industry as indicators of wood quality for different industrial processes and final paper products. The most variable character is the shape and size of the operculum, followed by the arrangement of the stamens in the mature buds and the density of veins visible in the leaves. Eucalyptus wood was used as raw material for the preparation of AC. The cracks will help you "read" the wood. The juvenile leaves are lance-shaped, 80–180 mm (3.1–7.1 in) long and 13–25 mm (0.51–0.98 in) wide. The fruit is a woody, hemispherical capsule 2–5 mm (0.079–0.197 in) long and 4–10 mm (0.16–0.39 in) wide on a pedicel 3–12 mm (0.12–0.47 in) long with the valves raised above the rim. This page was last edited on 23 December 2020, at 15:28. [citation needed]. Mackay, Norman and David Eastburn (eds) 1990. Recently, it has been used to produce decks (Patagonian cherry) and wooden floors (Andean cherry). Many people have discovered the tree’s rapid growth and prefer to plant it instead of native trees. Comparative Study on Physical and Mechanical Properties of Plywood Produced from Eucalyptus (Eucalyptus camaldulensis Dehn.) Abstract. It quickly toughens up and can withstand drought even whilst in forestry tubes. The wood has a moderate durability rating. at constant temperatures of either 20, 25 or 37 °C for 9 weeks. It makes an excellent bonsai and will readily regrow both from the base and from epicormic buds. The largest remaining stand of river red gum is the 65,000 ha (160,000 acres) Barmah-Millewa forest straddling the border of Victoria and New South Wales, due north of Melbourne. Eucalyptus lumber can come from any one of over 10 different species with such common names as blue gum, jarrah and swamp mahogany. [8][9], Seven subspecies of E. camaldulensis have been described and accepted by the Australian Plant Census. It is native to Australia. When eucalyptus dries it's extremely hard to split. Eucalyptus is hard to split. Seem. 0.6) is 4,800 kcal/kg. Eucalyptus camaldulensis is fast growing tree that is commonly used for firewood. The flower begins as an "invaginated receptacle". Fluorescence: A Secret Weapon in Wood Identification, Bow Woods (from a mathematical perspective), Brazilian Rosewood, East Indian, and Other Rosewoods, Genuine Lignum Vitae and Argentine Lignum Vitae, BOOK: WOOD! In 1847 Diederich von Schlechtendal gave the species the name Eucalyptus rostrata but the name was illegitimate (a nomen illegitimum) because it had already been applied by Cavanilles to a different species (now known as Eucalyptus robusta). Early growth of Eucalyptus camaldulensis under agroforestry conditions at Mafiga, Morogoro, Tanzania. Rabiul Alam1 1 Forestry and Wood … In the present study, pulp of wood branches (WBs) from Eucalyptus camaldulensis Dehnh. The wood has a moderate durability rating. pp 145-151. Research Journal of Recent Sciences _____ ISSN 2277-2502 Vol. [26] As the tree is inextricably linked with waterways, seed dispersion would logically be facilitated by floodwater. The fuel value of the wood (sp. A familiar and iconic tree, it is seen along many watercourses across inland Australia, providing shade in the extreme temperatures of central Australia. Small cracks will appear in the wood but overall it will still be wet. The trees provide a breeding habitat for fish during the flooding season, which also benefits aquatic bird life that depend on fish as a food source during their own breeding season. About 50 heads were harvested in the experimental logs. Eucalyptus camaldulensis is a tree that typically grows to a height of 20 metres (66 ft) but sometimes to 45 metres (148 ft) and often does not develop a lignotuber. [2][3][4][5][6], The limbs of river red gums, sometimes whole trees, often fall without warning so that camping or picnicking near them is dangerous, especially if a tree has dead limbs or the tree is under stress. It is commonly found along waterways and there are only a few locations where the species is found away from a watercourse. 1985. Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with River Red Gum. Based on the results, growth rates, correlations among measured properties, radial and … Distribution: Australia. It is somewhat brittle and is often cross-grained, making hand working difficult. This can occasionally lead to self-pollination, although the stigma does not become receptive until a few days after the operculum has been detached by the expanding stamens, and the flower's pollen has already been released. Eucalyptus camaldulensis, commonly known as the river red gum, [2] is a tree that is endemic to Australia.It has smooth white or cream-coloured bark, lance-shaped or curved adult leaves, flower buds in groups of seven or nine, white flowers and hemispherical fruit with the valves extending beyond the rim. [6] Its ability to tolerate drought and soil salinity, together with its prolific seed production, and capacity to reproduce when very young, mean that it is highly adaptable, and it has been declared invasive in South Africa, California, Jamaica, Spain, and Hawaii[31]. As one of dominant tree species of Eucalyptus plants, Eucalyptus camaldulensis is deemed as the renewable bioresources, however, the process properties of E. camaldulensis wood are further influenced by biomass extracts. E. camaldulensis readily germinates from both fresh seed and seed stored in cool dry conditions. FYI: I receive a commission on sales generated through links to Amazon, eBay, etc. The Properties of Eucalyptus Wood. globulus hybrids growing at Pinjarra, Western Australia, were harvested for assessment of wood fibre and wood properties of sawn timber. [19], Northern Territory aboriginal names for this species are:[20], Dimilan is the name of this tree in the Miriwoong language of the Kimberley. In World War II, Australians used the charcoal for their producer gas plants." The increasing scale of logging machinery is creating large areas of intensive soil disturbance and bare earth, which is likely to increase weed invasion and increase the likelihood of the extinction of rare understorey plants. Wood from the specie E. camaldulensis is commonly used in the paper industries, and the leaves have been reported to exhibit good antibacterial activity against the foodborne pathogen Listeria moncytogenes with good antioxidant properties (Nwabor et al., 2019). Identifying and Using Hundreds of Woods Worldwide, POSTER: Worldwide Woods: Ranked by Hardness. To test this idea and to establish the relationships between temperature, hydraulic conductivity, wood anatomy and wood density, we grew Eucalyptus camaldulensis (Dehn.) When eucalyptus dries it's extremely hard to split. River red gums contribute to the provision of nutrients and energy for other species through leaf and insect fall. A batch bio-sorption experiment was conducted on Eucalyptus camaldulensis Dehnh. It is also a good charcoal wood, and the steel industry in Argentina, for example, relies on its charcoal for steel-making. The sapwood is a creamy … grav. Copyright © 2008-2020 Eric Meier | All Rights Reserved. The specie is found in privately owned farm woodlots, windbreaks, tree lined avenues and riparian zones. and Meryta sinclairii (Hook.f.) Tree Size: 100-150 ft (30-46 m) tall, 3-5 ft (1-1.5 m) trunk diameter. The "snags" formed when river red gums fall into rivers such as the Glenelg, are an important part of river ecosystems, and vital habitat and breeding sites for native fish like river blackfish. One is the timing of the water flow, and the other is the minimisation of natural flooding. In regards to water regulation, there are two problems. Apiarists also use the tree’s flowers for honey production. All are members of the genus Eucalyptus, and although eucalyptus is a well-known native of Australia, much commercial wood comes from plantations in … The eucalyptus wood (E. camaldulensis) was obtained from a waste dump of a wood factory in the north of Iran. It is hardy to zone (UK) 9. The grain begins to twist and splitting a dry piece of the wood is not easy. When seeds are shed from a tree, most fall onto the ground below the crown, with some seed carried by the wind and water. Plantations occur in Argentina, Arizona, Brazil, Burkina Faso, California, Egypt, Kenya, Morocco, Nigeria, Pakistan, Senegal, Sierra Leone, Spain, Sri Lanka, Sudan, Tanzania, Uruguay, and Zimbabwe. [3], Although Dehnhardt was the first to formally describe E. camaldulensis, his book was largely unknown to the botanical community. It needs careful selection, as it tends to be quite reactive to changes in humidity (moves about a lot in service). grav. The fuel value of the wood (sp. Comparative Study on Physical and Mechanical Properties of Plywood Produced from Eucalyptus (Eucalyptus camaldulensis Dehn.) It retains enormous cultural significance to the Indigenous traditional owners, the Yorta Yorta Nation. The subspecies are:[3], The specific epithet (camaldulensis) is a reference to a private estate garden (L'Hortus Camaldulensis di Napoli) near the Camaldoli monastery in Naples, where Frederick Dehnhardt was the chief gardener. It is one of the most widely planted eucalypts in the world (c. 5,000 km2 (1,900 sq mi) planted) (NAS, 1980a). INTRODUCTION Eucalyptus camaldulensis Dehnh was one of the Wood density represents the weight of wood mass shown good adaptation to environmental condition. Eucalyptus camaldulensis (tree age: 4–5 years, site: Kanchanaburi Province, Thailand) were sup-plied by Siam Pulp and Paper (Ratchaburi, Thailand). From the top of the ovaries a structure called the style extends into the receptacle, to form the stigma. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information. 2.2. E. camaldulensis readily germinates from both fresh seed and seed stored in cool dry conditions. wood-branch in the form of woody sawdust nanoparticles (nSD-KF) to evaluate their potential efficiency as phosphate bio-sorption capacity. Therefore, the molecular and leaching characteristics of E. Eucalyptus camaldulensis is commonly known as river red gum because of the red heartwood. There is a paucity of old hollow-bearing trees which provide habitat for rare and threatened fauna such as the superb parrot, brush-tailed phascogale and inland carpet python. The clones grown at wetter Bhadrachalam and coastal Ongole sites had 2–3 times better growth and 5–6% higher pulp yield than those grown at a dry site in Mettupalayam. [32][33], After flowering, the stamens will detach. Nazrul Islam1,2, Khandkar-Siddikur Rahman1* and Md. [23], It has been recognised since around the early 1980s that managing water more effectively would ensure the maintenance of river red gum habitat. Traditionally used in rot resistant applications like stumps, fence posts and sleepers, more recently it has been recognised in craft furniture for its spectacular deep red colour and typical fiddleback figure. Eukaliptus kamaldulski (Eucalyptus camaldulensis) – gatunek drzewa należącego do rodziny mirtowatych.Pochodzi z Australii, ale uprawiany jest w wielu innych regionach świata.Jego łacińska nazwa camaldulensis wywodzi się od nazwy miasta Camaldoli we Włoszech, gdzie znajduje się klasztor Kamedułów i gdzie po raz pierwszy, w roku 1832, opisano ten gatunek. 0.6) is 4,800 kcal/kg. The formation of the noted Barmah red gum forests is due to a relatively recent geological event in the Murray-Darling Basin involving the Cadell Fault. [26], The association of the river red gum with water makes the tree a natural habitat choice, indeed sometimes the only choice in drier areas, for other species. About 25,000 years ago, displacement occurred along the Cadell fault, raising the eastern edge of the fault (which runs north-south) 8–12 metres (26–39 ft) above the floodplain. Eucalyptus camaldulensis, the river red gum, is a tree of the genus Eucalyptus, the river red gum, is a tree of the genus Eucalyptus Eucalyptus camaldulensis is quite comparable in calorific value with the commonly preferred fuelwood species of shisham (Dalbergia sissoo) and kikar (Acacia nilotica). Adult leaves are lance-shaped to curved, the same dull green or greyish green colour on both sides, 50–300 mm (2.0–11.8 in) long and 7–32 mm (0.28–1.26 in) wide on a petiole 8–33 mm (0.31–1.30 in) long. at constant temperatures of either 20, 25 or 37 °C for 9 weeks. Mature buds are oval to more or less spherical, green to creamy yellow, 6–9 mm (0.24–0.35 in) long and 4–6 mm (0.16–0.24 in) wide with a prominently beaked operculum 3–7 mm (0.12–0.28 in) long. To promote solid wood production, the diameter at breast height, height, stress-wave velocity, surface-released strain, basic density and compressive strength parallel to the grain were measured for 10 half-sib families of 12-year-old Eucalyptus camaldulensis Dehnh. It was introduced to South Africa in the mid to late 1800's. It is quite hard, dense (about 900 kg/m3 (1,500 lb/cu yd)), can take a fine polish and carves well. The Murray River flowed to the north around the Cadell Fault, creating the channel of the Edward River which exists today and through which much of the Murray River's waters still flow. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Abstract. River red gums; the Murrumbidgee River in flood. Many river red gums on the banks of the Barcoo River, south-west Queensland. [27] However, the Murray–Darling Basin Commission has recognised the importance of snags as aquatic habitat, and a moratorium on their removal from the Murray River has been recommended.[28]. [7], Eucalyptus camaldulensis was first formally described in 1832 by Friedrich Dehnhardt who published the description in Catalogus Plantarum Horti Camaldulensis. 123 Wood Sci Technol (2012) 46:143–155 147 As it was shown by Hamilton et al. The dried wood makes an excellent source of fuelwood and charcoal, and because of the fast growth of the tree it has been introduced for this purpose to many arid and semi-arid parts of the world. Eucalyptus is hard to split. Then the natural dam on the Goulburn River failed, the lake drained, and the Murray River abruptly deviated to the south and started to flow through the smaller Goulburn River channel, creating "The Barmah Choke" and "The Narrows" (where the river channel is unusually narrow), before entering into the proper Murray River channel again. Using industrial wood markets to sustain farm forestry: the Pakistan Experience. Research Journal of Recent Sciences _____ ISSN 2277-2502 Vol. A view down the Murray River – every tree pictured is a river red gum, A 700-year-old tree at the Wonga Wetlands, NSW. Eucalyptus plantations have been playing an important role in national industries, especially in wood supply, e.g. Marketing multipurpose tree products in Asia. It has smooth white or cream-coloured bark, lance-shaped or curved adult leaves, flower buds in groups of seven or nine, white flowers and hemispherical fruit with the valves extending beyond the rim. Eucalyptus camaldulensisis a common and widespread tree along watercourses over much of mainland Australia. Water management would include the removal of subsidies for irrigation, issuing water licenses, and the flooding of forests in suitable seasons.[26]. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees. Early growth of Eucalyptus camaldulensis under agroforestry conditions at Mafiga, Morogoro, Tanzania. Resources. It is frequently a dominant component of riparian communities, and is an iconic and important species of the Murray-Darling catchment, both ecologically and economically. Since the river red gum disperses its seed during spring, regulating the water may affect the species' ability to disperse using water as a dispersing agent, especially in floodplain red gum forests. "As firewood, the timber from Eucalyptus camaldulensis has few equals. These chambers are separated from the receptacle containing the male parts by a disc. River red gum seeds germinate readily after floods and require regular spring floods throughout their life to survive. However, grazing may aid regeneration by removing thick ground cover.[23]. Infrequent flooding due to water regulation provides inadequate water to recharge the floodplain subsoils that river red gums depend on. For example, grazing reduces the ability of the species to regenerate, as stock eat or trample the seedlings. Dissemination occurs mostly in spring and summer,[26][34] while natural flooding occurs during winter and spring. A river red gum near Bolin Bolin Billabong on the Yarra River. [23] The dense foliage of the tree also provides shade and shelter from the sun in drier areas. [34] It would also seem that as the seeding and flooding do not entirely coincide, it could be inferred that the conditions for germination, such as damp soil and plenty of sunlight, are more important in the continuation of the species than seed dispersal by means of floodwater. The aim of the study was to assess the impact of E. camaldulensis plantation established in a semi-arid area on native woody plants diversity and density. The iconic Australian gum tree, or Eucalyptus, is largely endemic to that continent and Tasmania and comprises over 700 species. The samples were separated into two parts, one part for soda pulping and the other part for wet-chemical and NIR analy-sis. Neither can seeds germinate in constantly flooded areas. Natural water run-off can also be affected, leaving some trees permanently flooded due to the build-up of water behind dams, or the permanent water flow. During flowering, pollen from the anthers can fall onto the stigma. Chingaipe TM. Using industrial wood markets to sustain farm forestry: the Pakistan Experience. and Simul (Bombax ceiba L.) Veneers Nazmul Alam D.M.1, Md. [23] The tree's preferred habitat of floodplains and watercourses also gives it the role of flood mitigator, which slows silt runoff. It is frequently a dominant component of riparian communities, and is an iconic and important species of the Murray-Darling catchment, both ecologically and economically. In: Raintree JB and Hermina AF (eds.). A gap in the forest must be available for the germinated seed to receive adequate sunlight.[33].

In the pulp and paper industry, several studies have been done to improve and enhance the properties of the mechanical, optical, and antimicrobial activities of pulp produced with different additives. The female parts of the flower, the ovaries, are contained in ovary chambers. Lack of flooding in floodplain areas will change the suitability of river red gum habitat as a breeding ground and food source for other species. Eucalypts may be found in most environments on the continent, from snowy to semiarid regions, with the exclusion of tropical rain forests.The Eucalyptus family has proven to be a valuable resource and has spread across the globe. The Goulburn River was dammed by the southern end of the fault to create a natural lake. Therefore, the molecular and leaching characteristics of E. It is in leaf all year. The wood makes fine charcoal, and is successfully used in Brazil for iron and steel production. Eucalyptus (/ ˌ juː k ə ˈ l ɪ p t ə s /) is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae.Along with several other genera in the tribe Eucalypteae, including Corymbia, they are commonly known as eucalypts. A section of the original Murray River channel immediately behind the fault was abandoned, and exists today as an empty channel known as Green Gully. Flowering mainly occurs in summer and the flowers are white. River red gum prefers soils with clay content. River Red Gum . Ultrasound to determine physical-mechanical properties of Eucalyptus camaldulensis wood, Wood Material Science & Engineering, DOI: 10.1080/17480272.2020.1830435 To link to this … Results and discussion Eucalyptus camaldulensis properties Density and fiber length are important parameters used by the pulping industry as indicators of wood quality for different industrial processes and final paper products. Eucalyptus Camaldulensis grows throughout South Africa, particularly in the Western Cape, Northern Cape, Gauteng and Free State. [33] Fertilisation will therefore occur with other flowers on the same tree or other flowers on a different tree. In addition, this plant is used for beekeeping in Brazil and Australia. This will result in stunted tree growth, death of existing trees, and poor conditions for seed germination. Scientific Name: Eucalyptus camaldulensis, Tree Size: 100-150 ft (30-46 m) tall, 3-5 ft (1-1.5 m) trunk diameter, Average Dried Weight: 54 lbs/ft3 (870 kg/m3), Specific Gravity (Basic, 12% MC): .67, .87, Modulus of Rupture: 17,940 lbf/in2 (123.8 MPa), Elastic Modulus: 1,711,000 lbf/in2 (11.80 GPa), Crushing Strength: 8,370 lbf/in2 (57.8 MPa), Shrinkage: Radial: 5.3%, Tangential: 8.8%, Volumetric: 14.1%, T/R Ratio: 1.7. trees growing in Thailand. Scientific Name: Eucalyptus camaldulensis. [18] Finally in 1934, William Blakely recognised Dehnhardt's priority and the name E. camaldulensis for river red gum was accepted. These conditions are perfect for river red gums, which rapidly formed forests in the area. The areas of significance to humans of Eucalyptus camaldulensis include agricultural, ecological, cultural, and recreational significance. globulus hybrids were made with the objective of producing trees that have commercial yields of wood or pulp when grown on saline land (Meddings et al.
