History of Sugar Gum Plantations in Western VictoriaSugar Gum (Eucalytpus cladocalyx) is a medium-tall tree, indigenous to South Australia. The best tree size and form of this species occurs in the southern Flinders Ranges where they grow to 30m in height.The first Sugar Gum plantations in western Victoria were established in 20-60m wide plantations in 1876. Sugar Gum was preferred by early settlers after it proved it could outgrow and outlive most of the other species trialled in this region. Plantations were principally established for shelter belts on naturally treeless plains, but the timber was then widely used for fence posts, rails and farm sheds. Sugar Gum continues to be planted across a range of sites affirming the belief that it is one of the best performing hardwood species in the medium to low rainfall regions of western Victoria. It is estimated that there are over 3000 hectares of Sugar Gum plantations originating from settler and Forests Commission plantings. Plantations in districts containing the best sawlogs are now subject to FSC certification to provide timber for milling to post, beam and board.The Multi-Purpose TreeSugar Gum is a species which has many excellent environmental benefits and wood properties:•The mature heartwood of Sugar Gum produces a strong, dense timber with a dry density of 1100 kg/m3 at 12% moisture content making it similar to Red Ironbark.•Results from a 25 year durability study ranked the mature heartwood of Sugar Gum as DC1 (Durability Class 1) for both above and below ground applications. This is the highest Australian durability classification.•Sugar Gum is one of the handful of Eucalypts which the CSIRO are commending for it’s sawing and drying properties as a young age eucalypt.•Being strong and durable, Sugar Gum produces timber suitable for heavy construction such as jetties and bridges. It also produces timber of very high strength and low defect for use in the building trade - as posts and beams, decking boards and cladding boards.

Most timbers supplied in the present market belong to the second b) category. Remember - intended use should always be stipulated in specifications.Popular sizes in stock200 x 75mm200 x 100mm200 x 200mm250 x 250mm300 x 200mm300 x 300mmLandscape GradeA lesser grade of milling which is cut close to heart like small log sleepers, or has more than 10% by volume residual sapwood.
