Testing time: Dr Ian Colquhoun from Alcoa demonstrates the use of tree injector syringes to Chris Scott and Kathy Anset from Ravenswood.

IN a bid to halt the decline of tuart trees in WA landholders from Yanchep through to Busselton are participating in a trial to test a newly identified treatment that will help boost the health of the sick trees.

For the past six years Alcoa has been working with Murdoch University’s Tuart Health Research Group to study possible tree declines and identify management options.

Alcoa mining environmental research manager Dr Ian Colquhoun said the research identified a treatment to improve the tree health.

“It involves injecting the tree with the fungicide phosphite and inserting nutrient plugs into the tuart’s trunk.

“This treatment has the potential to make a big difference to the tuart trees that are so highly valued by the local community,” Dr Colquhoun said.

Tests at various sites over the last four years have been positive.

To assist in the next phase of the trial, 20 local landowners are road testing the treatment with the tuart trees on their properties.

To launch the road test, a workshop was held last Sunday at the Lake Clifton-Herron Community Centre.

Organised by Alcoa, Murdoch University, City of Mandurah and Green Skills the session gave landowners the latest research information and meet test pioneer Peter Scott.

“This road test will enable us to test the tuart’s response to the treatment under a range of different environmental conditions,” Mr Scott said.
