asset protection zone weed removal
Much of the Australian continent is fire-prone. This is
particularly so in parts of Victoria where dry windy
summer conditions, combined with electrical storms lead
to frequent fires. Often these wildfires can be difficult to
suppress and may cause significant economic damage.
The Department of Sustainability and Environment (DSE)
has designated certain areas on the perimeter of the
Anglesea Township as Asset Protection Zones (APZs).
The APZ will provide the highest level of strategic
protection to human life, property and highly valued
assets vulnerable to damage by wildfire through radiant
heat and ember attack. It is a buffer zone between a
bush fire hazard and buildings, which is managed
progressively to minimise fuel loads and reduce potential
radiant heat levels, flame, ember and smoke attack on
life and property.
The width of the APZ will vary with slope, vegetation and
construction level. It consists of an area maintained to
minimal fuel loads. Some of the land managed by Alcoa
Fraser Ave land before weed removal
Anglesea (along Fraser Ave and bordering the Golf Club)
falls into a designated APZ. Fuel management in APZs
needs to be intensive and aims to maintain vegetation
characteristics within defined limits.
Alcoa Anglesea recently worked with a local contractor
to complete the removal of environmental woody weeds
including coast tea-tree and coastal wattle in order to
reduce the fuel load in this APZ. The weeds were either
hand pulled or cut with a chain saw and then mulched
on site. The work took over 140 person-hours to
complete. Over 50 cubic meters of mulch was then
removed from the site and taken to Eumeralla Scout
Camp for the mulching of their grounds.
This piece of land has important flora values, so
importantly we were able to comply with the APZ
guidelines by removing only the environmental weeds.
We will continue to manage the vegetation within this
area as part of our ongoing land management work.

PLANT OF THE ANGLESEA HEATH
Common Pampas grass (Cortaderia selloana)
Size:
height of tussock 4m, seed head up to 6m
Form:
robust long-lived perennial plant
Foliage:
Leaves to about 2 m long with a prominent
midrib and sharp edges of forward facing
short teeth
Flowers:
attractive plumed flower heads carried on tall
stems, generally white but can be pink or
mauve. Flowers mid March to late May
Habitat:
Pampas grass appears to have no particular
habitat preference and is found in a wide
range of ecosystems
Distribution:
native to Argentina, Bolivia, Ecuador and Peru,
but now established throughout Australia
Did you know?
Pampas grass used to be a fairly benign
garden plant in Australia, but the importation
of new strains in the
the aggressive weed we have today

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Lisa. Congratulations on being selected as an
Earthwatch Fellow for 2010. Tell us a little about the
project you will be working on.
I am being sponsored by Alcoa to head off to Gazi Bay
in Kenya with an expert team from Earthwatch. In
addition to rehabilitate degraded mangrove forests. In
addition to planting mangrove seedlings on two beach
sites, I will also help monitor the effect of these
plantations on rates of beach erosion and on the
animals dependent on these ecosystems.
What are you looking forward to most?
I am looking forward to seeing the practical, hands on
side of environmental research and having 11 whole
days to immerse myself in one project will be fantastic.
At work I often work on several projects at once, so to
be able to concentrate solely on one will be a luxury!
What motivated you to apply?
I work in the environmental field and completed my PhD
a few years ago. These two things have triggered my
interest in environmental research and I have applied
every year since I began working for Alcoa (7 years!).
This year just happened to be my lucky year!
