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.

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
