Introduction Availability of these four tablelands
species varies and they are often
marketed for their general features rather
than on a species basis. This applies to
flooring in particular (for example New
England Beech and Mixed Forest
Whites).
Distribution varies between the species.
The intention of this brochure is to
concentrate on their timber properties.
New England Blackbutt (E. campanulata/E. andrewsii) This is
the most commonly available
tablelands hardwood and is
described in detail in another
species brochure. There are a
number of other species utilised
by the tablelands industry to
produce a range of products, and
four of these species are described
on this species guide. This should
not be regarded as an exhaustive
list, as minor species such as
stringybarks (e.g. red, brown,
diehard) and peppermints
(particularly narrow-leaved) are
also utilised by the timber
industry.
Messmate Stringybark Eucalyptus obliqua
The heartwood is a pale brown with only
slight variation. The sapwood is a pale yellow
and quite distinguishable. The grain is quite
course with some interlocking grain and gum
vein being common. The heartwood is only
moderately durable (Class 3), limiting some
exterior applications. Sapwood is susceptible
to lyctid borer attack. Applications include
general framing, flooring, panelling, joinery
and furniture. Shrinkage is about 5.0% radial,
11.0% tangential.
Manna Gum (Ribbon Gum, White Gum)
Eucalyptus viminalis The heartwood is a pale pink to a pale
pinkish brown, with the slightly paler
sapwood not being overly distinctive in
colour. The texture is medium and even, and
grain is variable. The timber is generally
difficult to dry without significant degrade.
The heartwood is only moderately durable
(Class 3), limiting various external structural
applications where it is not adequately
protected. The timber works well and has
been widely used in a variety of applications
including, flooring, panelling, tool handles,
joinery, domestic structural framing.
Shrinkage is about 6% radial, 12% tangential.
Brown Barrel Eucalyptus fastigata The heartwood is pale brown, the sapwood
pale yellow and reasonably easily
distinguished. The colours are similar to those
of Messmate. The texture is medium and
even, with the grain being commonly
interlocked. Gum vein is a prevalent feature.
The timber is difficult to dry and collapse is
common. The timber is only of moderate
durability (Class 3), and the sapwood is
susceptible to lyctid borer. The timber is used
in construction applications (protected),
house framing and internal applications.
Shrinkage is about 6% radial, 9.5%
tangential.
Silvertop Stringybark Eucalyptus laevopinea
The heartwood is pale brown and may have a
pinkish tint. The sapwood is often not clearly
distinguishable. The texture is medium and
even, with the grain usually straight and
generally free of gum veins. The timber can
be prone to some collapse when drying. The
timber is of moderate durability (Class 3), and
the sapwood is apparently resistant to lyctid
borer. It is similar to Blackbutt in a lot of
characteristics and works well. The timber is
used in construction, house framing and
internal applications. Shrinkage is about 5%
radial, 8% tangential.
