Future technology tackles past failures
Unmanned aerial vehicles, or drones, are used as part of an integrated
approach to battle blackberry growth in the bush capital.
Our bush capital
Contemporary park management isn't
so much about managing the natural
environment, for nature has been
doing a fine job for millenniums.
As a Park Service what we do today
is manage the impact we humans have
brought to bear on this ancient
landscape - one of those impacts is
introduced invasive weeds.
Back in the 1830s blackberry
(Rubus fruticosus agg.) was brought
onto mainland Australia as a source of
European bush tucker for its fruit in
pies and jams.
Little did they know back then how
much native bush tucker was actually
Over the ensuing years, blackberry
spread and is now a weed of national
If left uncontrolled blackberry
smothers native vegetation, with
extensive blackberry thickets
providing harbour for feral animals
such as rabbits and increasing fire
behaviour and intensity.
Here in our bush capital you don't
have to travel too far to come across
this menacing invader.
When I started my career as a
ranger, we would use herbicide spray
backpacks in a vain attempt to control
this insidious weed as it marched
across our beautiful landscape. But
with time, and significant advances in
technology, our toolkit bag for weed
control has dramatically increased.
Today, as a park service we now
adopt a more holistic and integrated
Aside from the standard methods,
such as spraying by hand or physical
removal, we also use helicopters,
unmanned aerial drones and a special
In the past few weeks, our rangers
have been busy releasing the
microscopic phragmidium violaceum
fungus, known colloquially as
blackberry rust, at selected sites across
our bush capital.
This blackberry rust attacks the host
plant by causing the weed to lose its
This slows down the rate at which
the infected plant can colonise the
local landscape, allowing native
vegetation to then out-compete this
The fungus we are using was
developed by the CSIRO from
Research shows it only attacks
blackberry and is not harmful to
humans. You will recognise the fungus
by the rust like appearance on the
We have also been using a remote
controlled helicopter drone in the
battle against blackberry.
This unmanned small helicopter is
equipped with two 10 litre tanks of
herbicide which gives us access to an
infestation, otherwise impossible to
control on foot.
The drone technology saves us a
considerable amount of time and
precious resources, allowing more
areas, especially in rugged and remote
country, to be treated.
While we won't be putting away the
backpack sprays just yet, this
integrated approach to invasive weed
control will become more common.
The next time you are out picking
blackberries reflect on the impact this
nasty invasive weed is having across
our beautiful bush capital.
Time to swap
Canberrans can tear out invasive
species from their garden and swap
them for native varieties at the annual
autumn weed swap this weekend.
A range of attractive, native plants
will be available to swap, including
taller shrubs such as acacias, medium
shrubs such as correa dusky bell, wee
jasper grevillea and groundcovers
including creeping boobialla and
tussocky type plants such as lomandra
and river tussock.
The swap takes place from 8.30am
to 4.45pm on Saturday and Sunday at
green waste recycling centres at
Canberra Sand and Gravel in West
Belconnen and Corkhill Bros, near the
Mugga Lane landfill.
This event is a partnership between
the Australian Native Plants Society,
and the ACT government.
Territorians will be able to hand
over some of the most prolific and
dangerous weeds they can find, such as
cotoneaster, firethorn pyracantha,
privet and brooms, for free natives.
More information is available at
tams.act.gov.au/ or by calling
Canberra Connect on 13 22 81.
HEALTHY HOUSE VALUE
RISE FOR FIRST QUARTER
Canberra homes have increased in
value by 4.2 per cent in the first quarter
of 2015, the CoreLogic RP Data home
value index for March Canberra also
recorded growth above the combined
capitals figure for the quarter. The
home value index shows that Canberra
house values increased by 4.2 per cent
over the quarter while units have
increased by 3.7 per cent. The territory
performed poorly last year.
