Established by the United Nations General Assembly in 1972, WED gives a human face to environmental issues; empowers people to become active agents of sustainable and equitable development; promotes an understanding that communities are pivotal to changing attitudes towards environmental issues; and advocates partnership which will ensure all nations and peoples enjoy a safer and more prosperous future. World Environment Day is a people’s event with colourful activities such as street rallies, bicycle parades, green concerts, essays and poster competitions in schools, tree planting, as well as recycling and clean-up campaigns. Here at Alcoa Anglesea, there were several WED activities involving employees and the wider community. Over 1000 indigenous trees and shrubs were planted in the mining area by two dedicated tree planting crews. The first session consisting of Graeme Kerr, Leigh Fonseca, Maryann Thorp, Barry Knight, Tony Cust, Elise Jeffery and Chris Rolland, planted trees and shrubs along Coalmine Road as part of the strategy to minimise the visual impact of the open cut mine. The second session involved Daryl Carson, Keith Giles, Jonathon Morrow, Elise Jeffery and Chris Rolland planting and mulching trees and shrubs around the mine lunchroom area to remove weed species and create bird-friendly habitat using indigenous species for the smaller local birds. Alcoa Anglesea also participated with the Surf Coast Shire, CCMA, Barwon Water, Eco Logic and Rural Ambulance Victoria in an environmental awareness activitiy involving 300 school children. To complete the WED celebrations, Alcoa Anglesea was named a finalist at the United Nations WED Awards for land management. ANIMALS OF THE ANGLESEA HEATH Holly Leaf Lomatia (Lomatia ilicifolia) Lomatia Lomatia....from Greek loma, border or margin, and refers to the winged edge of the seeds ilicifolia ilicifolia... having leaves like holly Size: Form: Habitat: Foliage: Flowers: 0.5 m wide 1m high stiff erect shrub damp and sclerophyll forests, sclerophyll woodland, grassy low open forest dull green, leathery, crinkly, holly-like leaves to 15 cm with prominent veins racemes of glaborous cream flowers held above the foliage rarely seen in flower but flowers well after fire December to February Many plants in the Proteaceae family are susceptible to the fungus disease Cinnamon Fungus, Phytophthora cinnamomi, but species in this genus appear to be tolerant of the disease.

Graeme, it was great to see the mining crews involved in some tree planting to celebrate World Environment Day Day.. How did you enjoy the activity? It was good to help out. We planted a lot of trees along Coalmine Road. How do you consider the environment in your day to day work? On a daily basis, our main consideration for the environment for the mining operation is controlling the dust. Recently I was involved in some drainage work in the strip area diverting water and silt from Coalmine Road and a berm of the open cut from running across the strip area into the unmined heathland. Is it a challenge mining in an area as environmentally sensitive as Anglesea? It is a challenge however we work to minimise our environmental impact as best we can. For example, when we are clearing new areas, we work within the plans set out by Tony and Elise to ensure we don’t clear more than we have to. ...GRAEME KERR
