Tuart and marri trees have been uprooted to construct bike ramps while significant amounts of bush have been torn up to make tracks through the reserve.
City of Stirling parks and reserves manager Ian Hunter said the City had installed fencing as well as increased its presence in the area. He said people might not realise the importance and vulnerability of the animals and habitat in Star Swamp Reserve.
‘There are a number of important flora and fauna species which are present in Star Swamp, including several regionally threatened and endangered species such as several orchid species, the quenda, Carnaby and red tail cockatoo,’ Mr Hunter said.
The quenda is a small, reclusive native marsupial facing considerable habitat loss while the Carnaby cockatoo is on Australia’s endangered list, after significant habitat loss and nesting competition from introduced species.
Mr Hunter said police had been notified by the City on three occasions but no offenders had been identified or charged.
More than 100 incidents recorded in the year to date.
He said destruction of the native foliage would discourage native animals from living in the area.
City of Stirling officer Jo Taylor said she had met with a resident who had caught three teenage boys digging with shovels. When confronted, they ran off.
Ms Taylor said the vandals had already directly affected the diet of native birds in the area.
‘They have already started clearing the Parrot Bush site that the endangered black cockatoos feed on each day,’ Ms Taylor said.
Mr Hunter said vandalism had occurred throughout the year, but there was a marked increase during the school holiday period.
