VANDALS are impeding efforts to rehabilitate and revegetate the Canning River foreshore by damaging native trees in Shelley and Rossmoyne.
Recent damage includes four branches cut from a juvenile sheoak tree near Riverton Drive, Rossmoyne and four other branches snapped off the same tree.
Ten casuarina trees were also damaged in Shelley.
A City of Canning council report says the vandalism could be a result of nearby landowners wanting to maintain their river views, but an offender or offenders could not be identified.
“The establishment of young trees can be particularly difficult on the foreshore because views to the water are considered to improve property values and residential amenity,” the report says.
Council recently approved installing signs at the sites warning people against damaging vegetation and asking residents to report act of vandalism to the Swan River Trust.
These recent acts of vandalism make up some of the 20 reports lodged this year to the Swan River Trust of deliberate vegetation damage along the Canning and Swan river foreshores.
Trust riverbank manager Stephen Lloyd said there had been 159 reports of vegetation damage to plants on the foreshore in the past five years.
“Some of the biggest incidents have involved large gum trees in excess of 15m in height drilled at the base with poison administered and then plugged to try and hide the act,” he said.
Mr Lloyd said Trust officers tried to identify offenders to issue warnings and infringement notices and where that was not possible, erected warning signs to help deter vandals and identify vandals.
He said rehabilitation and revegetation efforts were important to the area as planting reduced erosion, helped foster the ecosystem and improved the amenity of the region for visitors.
“It is important to prevent foreshore damage to help protect the Swan Canning Riverpark’s fragile ecosystems and native animal habitats.”
