Growing trees for firewood

Growing and harvesting trees for firewood
is a potential farm forestry option for landholders across the Southern
Tablelands. Markets for firewood collected locally exist in Canberra
and Sydney. Firewood merchants are increasingly looking to source
sustainably grown and harvested wood. The challenge lies with growers
to successfully supply the market with a suitable product.
Demand for firewood
Up to 30,000 homes in Canberra use firewood
as a source of heating. This translates to a conservative estimate
of firewood consumption of 40,000 to 60,000 tonnes per year.
Supply of firewood
Firewood to the Canberra market has been
traditionally supplied by local remnant stands of timber, which
have been cleared for mostly grazing. These days firewood merchants
in Canberra market firewood, which has been collected from sometimes
more than 500km from the ACT. Many questions are being asked about
the impact that this practice is having on woodland and forest ecosystems
around Australia.
Products
The Canberra market is already responding
to increasing awareness regarding sustainable firewood harvesting.
Retail firewood products now available to consumers include blends
of seasoned hardwood eucalypt with ACT Forests softwood residue.
Canberra merchants have also indicated interest in sourcing and
marketing product that has a label of certification. In this case,
certification would indicate that the wood product was harvested
and processed in an ecologically sustainable manner.
Favoured firewood species amongst Canberra
consumers include River red gum, Red box, Yellow box, other box
species and Ironbark. These species have wood density properties
that make them amongst the highest quality firewood species in the
world. As these species are diminishing in the Southern Tablelands,
it has become timely to consider alternatives.
There are many alternative firewood species
that grow naturally throughout the Southern Tablelands. Local trees
that have more that acceptable firewood properties include Red Stringybark,
Scribbly gum, Snow gum, some casuarinas and numerous wattles. The
challenge lies not only in sustainable harvesting, but in engaging
consumers to embrace these alternative species.
Options for growing firewood
1. Managing existing stands of native timber
There is more than 1.5 million hectares
of existing native forest occurring on private land in the Southern
Tablelands. Much of this area of land is accessible for small scale
firewood harvesting operations. Under new State Government legislative
reform regarding private native forests, landholders will be able
to
conduct commercial firewood operations, as long as individuals can
demonstrate ecologically sensitive long term management of their
forest estate. Contact your local DIPNR office for information about
the Native Vegetation Act 2003.
2. Planting firewood species
Planting firewood farm forests can
be conducted in many ways. Some of these ways include;
- Interplant firewood species amongst other
forestry species, such as Radiata pines to diversify crop products.
- Plant mixed species plantations with local
hardwoods.
- Stagger harvesting over several events
to maximise firewood yield.
3. Direct seeding
Direct seeding is a cheap and efficient method
of establishing trees. Choose firewood species that are accept to
the market and manage the stand as you would a plantation (thinning
and pruning). Ring Greening Australia ACT & SE NSW (02 6253
3035) for direct seeding information.
