2009 Case Study: 20th Anniversary of Tree Planting Weekends

The stream zones leading into the Swan River were given a boost in 2009 thanks to the planting of 25,000 trees, by a group of Alcoa employees, in the Wooroloo Brook catchment near Perth.
Around 50 Alcoa employees and their family members participated in Alcoa’s annual Tree Planting Weekend, working alongside the Wooroloo Brook Land Conservation District Committee to rehabilitate and revegetate the stream zones draining into the Wooroloo Brook and Swan River in Western Australia. Over two days, each volunteer planted around 500 trees.
2009 marked the 20th anniversary of Alcoa Tree Planting Weekends.

“Community volunteering and looking for ways to become part of the solution to climate change are integral to Alcoa’s values, which is a big part of why we’ve been holding tree planting weekends since 1989,” said Alcoa’s General Manager of Carbon Strategy Tim McAuliffe.
Wooroloo Brook Land Conservation District Committee Chairman Bob Huston said: “The Alcoa volunteers have been planting seedlings for us for 18 years straight.  Because of them, we have been able to plant in wet, boggy degraded areas where the planting can only be done by hand and not machines.
“Knowing we have 50-plus volunteers for a weekend has also meant we could take on a very big planting project each year.  Alcoa employees have planted over 540,000 seedlings in our catchment alone over the years.”
Back in 2003, in response to global climate change, Alcoa launched its ‘Ten Million Trees’ program in which Alcoa volunteers aim to plant ten million new trees by 2020. All the trees planted in the Wooroloo Brook catchment have been counted towards the ‘Ten Million Trees’ goal.
“Those ten million new trees will absorb more than 250,000 metric tonnes of carbon dioxide each year during their lifetime,” Tim said.
‘Ten Million Trees’ grew from Alcoa’s successful ‘One Million Trees’ program which began in 1998 with the goal of Alcoa employees planting a million trees within 10 years.  Employees, contractors and their families at more than 140 Alcoa locations in 20 countries raced to the goal in half the time expected.
