Eucalyptus cloeziana is native to Queensland Australia. It is among the more important plantation species in Zimbabwe, where it is used for poles and pulping. Plantations have been established in Zambia to supply timber for industrial use.
Eucalyptus cloeziana produces very good poles, having few equals as telephone or transmission poles, due to their form, strength and durability. The wood is also used for construction, cladding, railway sleepers, bridge planking, piers, posts and mine props, and is suitable for flooring, joinery, ship building, vehicle bodies, handles, ladders, sporting goods, agricultural implements and turnery.
It is used as fuelwood and it can be made into charcoal of good quality. The flowers provide bee forage. The heartwood is yellow-brown; the up to 2. The grain is straight, texture fairly fine and uniform. It dries fairly slowly, with a tendency to checking and warping, but with careful handling good results can be obtained. The wood is strong and very tough.

The wood saws and works remarkably well, which is probably due to the straight grain, but it splits readily. It holds nails and screws well, but pre-boring is necessary. It planes to an attractive finish and polishes well. The wood is very durable and highly resistant to termites. The sapwood is not susceptible to Lyctus borers. The heartwood is extremely resistant to impregnation with preservatives. The leaves yield up to 1. In the savanna eucalyptuw of Nigeria a mean annual height growth of 1.
In the southern savanna zone of Nigeria the annual height growth in the first 2 years was 2. In experiments with Eucalyptus cloeziana in Congo the average height of different provenances was Eucalyptus comprises about species, endemic to Australia, except for about 10 species in the eastern part of South-East Asia. The genus is divided into several subgenera 7—10, depending on the authorwhich are subdivided into many sections and series. The results of phylogenetic studies within Eucalyptus suggest that the genus is polyphyletic, hence not of a single evolutionary origin, and consequently it has been proposed to divide the genus into several distinct genera.
This has not yet been done, mainly because of the nomenclatural whirlpool this would bring about. Eucalyptus species hybridize easily, which adds to the taxonomic complexity. Many Eucalyptus species are cultivated outside their natural distribution area, in tropical, subtropical and temperate regions, because of their rapid growth and adaptation to a wide range of ecological conditions.
Eucalyptus cloeziana — Noosa’s Native Plants
In Africa Eucalyptus globulus Labill. Nowadays the main commercial species in Africa are Eucalyptus grandis W. Hill ex Maiden in more fertile locations, Eucalyptus camaldulensis Dehnh. Many other Eucalyptus species have been introduced into tropical Africa, of which the actual distribution and importance in tropical Africa are not exactly known, but which are surely less important.
Less important Eucalyptus species that are planted in tropical Africa and that are not obviously less used for clozeiana than for other purposes, such as fuelwood, pulping, erosion control or ornamental purposes, include the following:.
The wood is used for heavy construction, piles, poles and cloeziaan sleepers. It grows well in Madagascar, especially at low altitudes near the coast, and it has been planted in Kenya and Tanzania.
The wood is strong and very durable, but frequent gum pockets and rings are a defect, resulting in the wood being used mainly for poles, piles, posts, railway sleepers, mining constructions and hardboard production. It is also used as fuelwood and for charcoal making.
The wood is particularly valued for flooring parquetry, dance floorsbut also for construction, furniture, railway sleepers, poles, posts, vehicles, and wheelwork. It is also used as fuelwood.
Eucalyptus microcorys is also used in windbreaks and as a shade tree, and the flowers provide bee forage. The wood is used for construction, poles, piles, posts and railway sleepers. It is one of the most important hardwood species in Australia.
The wood is used for construction, interior trim, furniture, boxes, poles, piles, posts, railway sleepers, veneer, plywood and woodwool.
It is also used as fuelwood, for charcoal making and for pulping. It is one of the main hardwoods of Australia, used for construction, flooring, panelling, poles, posts, railway sleepers and veneer. It makes good charcoal. It is native to coastal eastern Australia, and has given good results after planting in Rwanda and Zimbabwe. It yields an important construction timber in Australia, and the eucslyptus is also suitable for flooring, interior trim, eucalyotus building, vehicle bodies, agricultural implements, mine props, cloeziaan sleepers, poles and piles.
It is hard, tough, stiff and very strong. Eucalyptud traditional medicine in DR Congo Eucalyptus propinqua is one of a range of Eucalyptus species that are recorded to be used for treatment of respiratory problems, fever and skin diseases.
The wood is considered one of the best Australian hardwoods. It is used for construction, boat building and railway sleepers, and also used as fuelwood and for charcoal making. It is stiff, strong, tough and hard. The wood is used for construction, railway sleepers and posts.
It is also used as fuelwood and for making charcoal. It is strong, stiff and hard. The leaf oil has been produced commercially in South Africa, where it was used as a clkeziana agent in the mining industry. Eucalyptus sideroxylon is also planted as a shade euczlyptus ornamental tree, and the flowers provide bee forage.
The tree is suitable for humid highland conditions, but it is sensitive to frost. It prefers well-drained, neutral to acidic, medium-textured soils.
Eucalyptus cloeziana is propagated by seed. Recorded seed weights range from 2. The seed can be stored for several years under dry, cold and airtight conditions. Pre-treatment before ducalyptus is not needed, but the germination rate is often poor. Seedlings are planted out in the field when they are 4—5 months old.
Eucalyptus cloeziana coppices well. When grown for poles, coppice rotations of 6—12 years are employed. Eucalyptus cloeziana is resistant to the eucalyptus snout beetle Gonipterus scutellatusan important pest of many other Eucalyptus spp.
Seedlings in the nursery are susceptible to damping off, and they may suffer from termite attacks. In an experiment in Zambia mean annual increments after 12 years were Eucalyptus cloeziana shows a large genetic variability, indicating potential for selection of provenances with favourable characteristics. Eucalyptus cloeziana combines favourable wood properties with good growth characteristics, abundant coppice regeneration and an attractive appearance.
