EUCALYPT SAWLOG SPECIES

The sawlog species have been selected for the South-West of Western Australia, which has a Mediterranean climate with a high evaporation rate. Low rainfall is regarded as 450 - 600 mm, medium 600 - 700 mm and high, above 700 mm. Species have been planted beyond their rainfall definitions as silviculture management can be manipulated to manage water-stress and improve wood production.

	*Eucalyptus globulus* (Western Blue Gum) Eucalyptus globulus has been selected for deep fertile soils with a high rainfall. To provide the best genetics for such a project, the Western Blue Gum breeding program has been used to select trees with a higher weighting for tree form and branch size. Thus, whilst these trees would satisfy a pulp and paper project, they give the option of better form for sawlog objectives.
	*Eucalyptus saligna* (Sydney Blue Gum) Eucalyptus saligna has been selected for moderately fertile deep soils in high rainfall areas. The best provenances have been identified and seed collections made from a single family/provenance breeding trial in the South-West Western Australia. These are presently available for sale. The best single tree selections have been successfully grafted and established into an orchard in 2002.
	*Eucalyptus viminalis* (Manna Gum) Eucalyptus viminalis has been selected for deep fertile soils with a high rainfall. The best provenance has been identified from three replicated family/provenance breeding trial across the South-West Western Australia. Using this data, special seed collections from the best provenance stands are available. The best single tree selections have been successfully grafted and established into an orchard in 2002.
	*Eucalyptus cladocalyx* (Sugar Gum) Eucalyptus cladocalyx has a tolerance to a range of soil types in low rainfall areas. Whilst family breeding trials have only been established in south-west Western Australia in 2001, the best provenance has been identified from trials established in the Eastern States. Special provenance collections from thinned stands are available.
	*Corymbia maculata* (Spotted Gum) Corymbia maculata can adapt to a wide range of soils in the medium rainfall area. It is favoured for its clean straight bole and natural branch shed. The best provenance has been identified from three replicated subspecies/provenance breeding trials across the South-West of Western Australia. To produce a clonal orchard, only the best selection from each of the C.maculata provenances could be selected for cloning. The first clonal seed from this orchard is available for purchase this season.
	*Eucalyptus botryoides* (Southern Mahogany) Eucalyptus botryiodes has been selected for poor sandy soils or moderately fertile loams in high rainfall areas. The best provenance has been identified from three replicated subspecies/provenance breeding trials in the South-West of Western Australia. One of the trials has been converted into a seed orchard with seed from the best trees available for purchase this season.
	*Eucalyptus tricarpa* (Iron bark) Eucalyptus tricarpa is a hardy species selected for fairly heavy alluvial soils, clay loams and better quality sandy loams in low rainfall areas. Seed is available of the best provenances, identified from two species/provenance/family trials in the South-West of Western Australia. Open pollinated seedling seed orchards have been established and the best selections are being cloned for orchard establishment in 2003.
	*Eucalyptus occidentalis* (Swamp Yate) This species is native to Western Australia and is salt-tolerant. The species can survive on poorly drained, heavy textured soils in low rainfall areas. Open pollinated seedling seed orchards have been established and the best selections are continually being cloned as they are identified. The first grafts in the clonal orchard are producing seed.
