The internationally-renowned Mary Carroll Park wetlands in Gosnells have been subjected to repeated acts of vandalism and poisoning, prompting the City of Gosnells to install new surveillance measures. Since January, trees, vegetation, and native wildlife at the wetlands have been manually cleared and poisoned on multiple occasions.
City Responds with Enhanced Monitoring
City of Gosnells chief executive officer Ian Cowie confirmed that the local government has been actively monitoring the site since the first incident was identified. However, trail cameras and electronic display boards installed by the city have been repeatedly tampered with, and one camera was stolen. In response, a mobile CCTV tower has been deployed to improve monitoring and gather evidence for potential prosecution.
“Any evidence collected may support future enforcement action or prosecution should those responsible be identified,” Mr Cowie said. The trail cameras cost approximately $150 to $200 each.
New Signage and Fencing Installed
The city has also erected a large sign and temporary fencing to raise public awareness and encourage vigilance. The sign cost $2,200 to produce and install, while the fencing costs $626 per quarter. The sign will remain in place until replacement vegetation has grown to a suitable size, a process that may take several years.
Mr Cowie emphasized the ecological importance of the wetlands, stating, “The wetlands provide essential habitat for migratory birds and native wildlife, and need to be protected. The Friends of Mary Carroll Park, the Armadale Gosnells Landcare Group and city staff work hard to keep this conservation category wetland in excellent condition. This vandalism is extremely disappointing for everyone involved.”
Community Reaction
The Armadale Gosnells Landcare Group expressed gratitude via a Facebook post on Saturday, thanking the city for installing the new signs and security cameras at the main vandalism location on May Street. The group noted, “While the sign won’t replace the trees that have been chain sawed down or the plants that have been pulled out, it will hopefully raise awareness and increase community monitoring of the area.”
The Mary Carroll Park wetlands recently underwent a two-year, $3.5 million redevelopment project completed in April, which included the installation of the largest all-abilities playground in Gosnells, a new pedestrian bridge across the wetlands, and more accessible community spaces.
Appeal for Public Assistance
Mr Cowie urged anyone who witnesses vegetation destruction or other forms of vandalism in city parks to report it by noting vehicle registration details, vehicle descriptions, and descriptions of any persons involved, and contacting the city at 9397 3000. The city is also collaborating with relevant authorities as needed.
