Fraser Avenue is a parcel of land owned by Alcoa between Coalmine Road and the Anglesea township. It is well utilised by the local community for passive recreation such as walking. Since Tree Day started in 1996 more than 1.5 million volunteers have planted over 11.5 million native trees and shrubs! And we can add another 400 to that impressive total! Usually held on the last Sunday of July Anglesea got in early for National Tree Day this year, holding it’s planting day on July 15. The planting undertaken by Alcoa Anglesea employees will rehabilitate an informal trail and re-direct pedestrian traffic to an adjacent walking track. Part of the Surf Coast walk alignment, the adjacent track provides for a better walking experience on a maintainable surface. Directional signage will be installed along the track in the coming weeks. Braving the winter chill, seven keen employees donned beanies and scarves and planted around 400 native shrubs on Alcoa’s freehold land at Fraser Avenue in Anglesea. Coast wattle, an unwelcome local weed, was also removed. Thank you to the hard working tree planters of Nick Brockman, Grace McKenzie, Nicci Marris, David Brown, Maryann Thorp, Cameron Ingles and Elise Jeffery and thanks to Dave Ryan for delivering the hard earned morning tea.

It was great to get out and get our hands dirty planting some trees – particularly when you know it will benefit our freehold land and the local environment. Can’t say we saw much sunshine. It was pretty chilly to start but we soon warmed up. What would you say to others to get them out and about tree planting? Have a go – it was really good to try something different from the jobs I do every day. It was also great to work alongside others from Anglesea that I usually don’t have a lot to do with. How do you consider the environment in your every day work? Although I don’t think of it every minute of the day, it is hard to ignore the environment - we work in an area surrounded by some pretty spectacular heathland. You see it driving to work, at work and going home again. ...CAMERON INGLES
