The Shelley Rossmoyne foreshore, Shelley Beach Park and an area between Beryl and Modillion avenues were all under threat.

The City launched a series of projects, now in their final stages, to combat erosion.

Canning Commissioner Linton Reynolds said erosion was one of the most serious issues facing the Canning and Swan River systems.

‘Erosion causes deterioration of the river banks, which can in turn have a detrimental effect on the ecosystem,’ Mr Reynolds said.

‘The soil erosion can lead to unstable river banks which, if allowed to deteriorate, could undermine paths and infrastructure and damage trees and animal habitats.’

Techniques including stabilisation, beach restoration, revegetation and bioengineering were used to repair and protect the foreshore area.

Mr Reynolds said bioengineering technique brush mattressing was also used to help aid erosion.

‘Mattresses, which are used to protect native seedlings, are made of twigs from native tree species and are placed in front of newly planted seedlings,’ he said.

‘When the seedlings mature, the mattressing breaks down into mulch, which will feed the plants.’

Mr Reynolds said since works had been completed, no further erosion had been uncovered at the sites.

The foreshore stabilisation works were partly funded by the Swan River Trust through the Riverbank Grant Scheme.
