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 from parts of forests and parks. By reducing these fuels, a bushfire that either burns into a fuel reduced area or starts in one will have 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 land and resource management objectives: > fuel management: protecting life and property from uncontrolled wildfire through the 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. Prescribed burning at Anglesea On March 1st a prescribed burn was carried out in the Anglesea Heath in a sector bounded by Coalmine Road, Pipeline Track and Raven Track. At approx. 16:00, Alcoa Anglesea was informed by Parks Victoria that the control burn had moved beyond its nominated perimeter. An investigation into the Coalmine Road burn indicates the cause was a spot over approx. 200 metres ahead of the fuel reduction burn. Embers from the planned burn dropped outside the burn perimeter and burnt an additional 75 hectares running parallel with Alcoa Boundary track and extending the west boundary towards Harrison Track South. Approx. 40 hectares of this area was identified in the current Barwon - Otways Fire Operations Plan for planned fuel reduction burning in the next two years. The result is excellent protection for the Power Station from wildfire and over the coming months small burns will be carried out to further consolidate the area by bringing the burn boundary out to strategic tracks. 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. 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, because fire is a natural part of the forest’s ecology, it should be used freely as a management tool. The perceptions by Australians of their environment continue to evolve. Fire was, is, and will remain, part of ecological Australia.

We moved to WA in February 2006 for my role as Environmental Scientist at the Kwinana Refinery. This role was focussed on consulting to the site departments on environmental issues including compliance with environmental licence and ISO14001 certification, as well as driving improvements in environmental performance. Your new role is in ABS - how does that relate to your environmental background? There is a real similarity in the role as an Environmental Scientist with that of an ABS Consultant in that the work involves influencing people to do their work differently to achieve improvements in performance. What are your impressions of Anglesea and what will be your focus first up? I’ve been working at Anglesea since just after Easter and I’m thrilled to be working in a plant where you can learn everyone’s name within a couple of weeks, and form strong relationships with a large proportion of the site people. There has been a very positive response to my role, and I’ve encountered an attitude generally that is open to the prospect of doing things differently. The main focus in the first couple of months will be to try and get key activities and processes displayed visually in order to highlight and solve problems. ...NICK BROCKMAN
