Prescribed burning
While every effort is made to prevent fires from
starting, Victoria will always experience bushfires
from either natural or human causes. These
bushfires can threaten human life, property, assets
and, at times, the environment. One way of
protecting assets and also limiting the spread and
severity of bushfires is by strategically reducing the
‘fuel’ in our parks and forests. Fuel reduction burns
are fires of low intensity used to remove the fine,
more flammable fuel. By doing this, a bushfire that
either burns into a fuel reduced area, or starts in
one will have a lower flame height, reduced
intensity and will spread at a slower rate, making
fire fighting easier.
The term ‘prescribed burning’ refers to the use of
fire to achieve planned burn land and resource
management objectives:
> fuel management: protecting life and property
from uncontrolled wildfire through development
and implementation of strategies for fire prevention
and suppression;
> flora and fauna management: active use of
controlled fire to alter habitat structure and plant
and animal community composition to achieve
biodiversity conservation outcomes.
The Department of Sustainability and Environment
and Parks Victoria have just released the Otway
Fire Operations Plan for 2009/10 to 2011/12.
The Anglesea Heath Consultative Committee, of
which Alcoa Anglesea is a member, provided
comments on the draft plan, and some of these
comments were incorporated into the final version.
The plan nominates four burns for the Anglesea
area in 2009/10. These include:
> Anglesea ovals (41 ha)
> Gum Flats Road (735 ha)
> Messmate Track (239 ha)
> Pipeline Track (75 ha)
Conducting prescribed burns is not without risk.
However, the risks associated with fuel reduction
burning under controlled conditions are far outweighed by the increased risk of bushfire if no fuel
reduction has occurred.
The Otway Fire Operations Plan can be viewed at
www.dse.vic.gov.au.
Within the community there exists a range of views
regarding the role of fire. These range from the
belief that there should be no interference to
natural fire patterns through to the belief that fire
should be used freely as a management tool
because it is a natural part of the forest ecology.
Regardless of viewpoint, fire was, is and will remain
part of ecological Australia.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Lisa, I understand you are the Chairperson of the
Anglesea Heath Consultative Committee. What was you
role in regard to the Otway Fire Operations Plan?
I attended the draft Fire Operations Plan community
consultation meeting to hear how the plan would be
implemented, and I also co-ordinated the response to DSE
on behalf of the Anglesea Heath Consultative Committee. We
had some changes that we wanted to make to the plan. DSE
listened to our reasoning for these changes, and some were
included in the plan.
Tell me a little about the Anglesea Heath Consultative
Committee.
The committee is made up of representatives from Alcoa,
Parks Victoria, ANGAIR, Deakin University, and Surf Coast
Shire. The committee works to conserve the Anglesea Heath
and deals with any issues that arise which affect the Heath.
...LISA MILLS
