Introduction The most commonly
available hardwood species from the coastal forests of New South
Wales are described in individual species guides.
There are
however a number of other coastal species that are less commonly
available, either because their distribution is more limited to
certain regions, or they tend to be marketed as a generic hardwood
product. These species are described in this brochure, with a brief
note on their distribution as a guide to where sawn product may be
sourced locally. Like the brochure on the tablelands species, this
is not an exhaustive list.
Grey Box Eucalyptus
microcarpa Eucalyptus moluccana E. moluccana is
found mainly in the central and north coast areas of NSW and into
southern and central Queensland. E. microcarpa is found on the
western slopes and eastern edge of the western plains of NSW, the
adjacent areas of south eastern Queensland and also in central
western and northern Victoria. The heartwood is a pale coloured
yellowish brown, with the sapwood being distinctly lighter in
colour. The texture is generally fine and even, with the grain
having characteristic interlocking. The timber is also generally
free of gum vein. Applications include heavy engineering, marine
structures, framework, panelling, cladding, flooring and decking.
The heartwood is very durable (Class 1). Shrinkage is about 3.5%
radial, 7.5% tangential.
Grey Gum Eucalyptus
punctata Small-fruited Grey Gum E.
propinqua The distribution of Grey Gums ranges between
Jervis Bay in the south of New South Wales up to Maryborough in
Queensland. The heartwood is a deep red in colour, with the smaller
fruited variety being slightly lighter in colour. The sapwood is
distinctly paler in both variants. The heartwood is highly durable
(Class 1), which allows a broad range of exterior applications. The
timber is close grained with some interlocking, and is very dense.
The timber is often marked with grub holes. Sapwood is resistant to
lyctid borer attack. Applications include heavy engineering, poles,
sleepers, flooring and decking. Shrinkage is about 4.5% radial, 7%
tangential.
Yellow
Stringybark Eucalyptus muellerana Yellow
Stringybark is found in the coastal plains and adjacent ranges of
Victoria and southern New South Wales. The heartwood is yellowish
brown with a pinkish tinge. The sapwood is slightly paler. The
texture is medium and even, with the grain often being interlocked.
The timber resembles Blackbutt in colour and texture. Yellow
Stringybark is probably the best of the commercially available
stringybarks in terms of properties. The heartwood is durable (Class
2) and the sapwood is not susceptible to Lyctid attack. The timber's
working characteristics are good and applications include framing,
decking, flooring, sleepers, poles, piles and crossarms. Shrinkage
is about 4.5% radial, 7.5% tangential.
Red Mahogany Eucalyptus
resinifera Red Mahogany is found in the coastal forests
of the NSW mid north coast and north coast, extending into south
east Queensland and further north. The heartwood is dark red, with a
distinctly paler sapwood. The texture is medium and even, with the
grain slightly interlocked. Pin holes can be a distinctive feature.
The heartwood is durable (Class 2) and the sapwood is susceptible to
Lyctid attack. Whilst it is a much sought after species for its
colour and grain, it is not available in large quantities. The
timber's working characteristics are good and applications include
framing, decking, flooring, panelling and general construction.
Shrinkage is about 4% radial, 6% tangential.
Bloodwoods Corymbia
gummifera Corymbia intermedia There are
number of Bloodwood species found in NSW, but the two most common
coastal species are Red Bloodwood (C. gummifera) and Pink
Bloodwood (C. intermedia). Red Bloodwood is distributed in the
coastal forests from north eastern Victoria to south eastern
Queensland. Pink Bloodwood is found from the NSW mid north coast to
north Queensland. Bloodwoods are most easily distinguished by their
persistent, rough, tessellated bark.
The heartwood of Red
Bloodwood is pink to dark red, with a distinctly paler sapwood. The
texture is course and the grain is often interlocked. A feature of
the timber is the presence of gum veins, which often limits its
suitability for sawn timber (gum veins may also open up in drying).
However a good piece of sawn Red Bloodwood is prized for its
attractive grain. The heartwood is very durable (Class 1) and
shrinkage relatively low (about 3% radial, 4% tangential). The
sapwood is susceptible to Lyctid attack. Red Bloodwood is used
for sawn timber production if the presence of gum veins is not
limiting. Its durability makes it ideal for in ground uses such as
posts. Pink Bloodwood is generally not regarded as a commercially
valuable species for sawn production but is suitable for
posts. > |
