ANGLESEA ENVIRONMENT REPORT NOVEMBER 2006
ACTION event
Alcoa Anglesea and local volunteer environmental
group Anglesea Coast Action worked together to
tackle coastal weeds in the area opposite Four
Kings carpark on the Anglesea foreshore during
November. A range of range of woody
environmental weed species were removed
including mirror bush, cypress, box thorn, coast
tea-tree and polygala.
Alongside employees from the Great Ocean Road
Coastal Committee (GORCC), who manage the
local foreshore area, Alcoa Anglesea participants
on the day were Chris Rolland, Mike Allden, Phil
Stafford, Ben Craig, Barry Knight, Elise Jeffery and
Anthea Daley with Ron McRae, Greg Lewis and
Peter Thompson providing assistance with heavy
machinery later in the week.
Since the Ash Wednesday bush fire in 1983 the
Coastal Reserve at Anglesea has become infested
with environmental weeds. At this particular site,
it’s important to remove environmental weeds to
restore the sand dunes to their original condition
and prevent weed infestations into the adjacent
Moonah (Melaleuca lanceolata) Woodland
Community that is listed under the Flora and Fauna
Guarantee Act as a threatened community.
Anglesea Coast Action were delighted with the
large amount of progress made at this site with
Alcoa’s help and will continue improvement works
here in the months ahead. These working bees
were part of Alcoa’s ACTION grant program
where the Alcoa Foundation donates US$3000
and a number of volunteer hours towards a
community improvement project. This particular
activity certainly put us to the test as it’s been one
of the most physically challenging we’ve
undertaken!
Anglesea Coast Action volunteers meets regularly
to perform working bees on the Anglesea and
Point Roadknight foreshores. New volunteers are
always welcome. Interested people can contact
Carl Rayner at: [email protected]

OUR ENVIRONMENT AND OUR EMPLOYEES..
Mike, what prompted you to volunteer your day to
a the community ACTION grant for Coast Action?
Wayne Pavletich asked me if I would like to lend a helping
hand. The impending weekend shutdown impacted upon
volunteer numbers and I was happy to oblige.
What did you do and did you enjoy getting out of
the office for a while?
Since the Ash Wednesday bush fires the coastal reserve at
Anglesea has become infested with environmental weeds. I
formed part of the team who removed the weeds that were
lopped with chainsaws and hand saws and presented it for
mulching. The work was fairly physical, but I did enjoy the
change and think the work was appreciated.
What other volunteering have you been involved
with?
This is the first ACTION grant I have been involved with. But
I’m willing to have a go when required.
...MIKE ALLDEN
