Tackling weeds
In response to community concern over herbicide spraying, Redland City Council is developing an Integrated Weed Management Plan for Coochiemudlo Island.
This involves multiple approaches including native plant competition and non-chemical intervention with the ultimate goal to achieve long-term weed control without damaging the environment.
In the absence of a site specific plan, previous weeding operations should have been guided by recommendations from the 2004 Coochiemudlo Land Management Plan, Redlands Pest Management and Conservation Plans (see hereunder)

In November 2014 Coastcare asked Redland City Council to
- Work collaboratively with a motivated community to share the care for the environment
- Support the Ramsar Convention and encourage engagement with stakeholders
- Demonstrate leadership and promote ecologically sustainable action
- Adopt chemical/herbicide-free buffer zones around the Melaleuca Wetlands, sensitive water courses (ie Curlew Creek) and fore-dunes
- Respond with an Integrated Weed Management Plan for the island with minimal chemical use
- Promote alternative weed eradication methods – competitive native regeneration/planting. hand-weeding, bio and thermal control
In March 2015 the International Agency for Research on Cancer, an agency under the World Health Organisation, found sufficient evidence to reclassify glyphosate ( commonly known as Round-up) and four organophosphate pesticides as probably carcinogenic. Internationally, as countries ban these products, the warnings are being sounded in Australia (ie NSW Government Glyphosate and Organophosphates Fact Sheet).
At a meeting with senior Council officers in August 2015, Coastcare asked Council to work together and trustfully with a motivated community to share the care for the environment. We sought the development of an Integrated Weed Management Plan with non-chemical control of weeds within five years. We also encouraged Council to adopt the use of saturated steam, an effective non-toxic treatment used by Councils around Australia with particular success in North Queensland.
In September 2015 a walk was undertaken around the island by Redland City Council senior management with an inspection of the asparagus-ridden western mangrove track and cats claw infestation at the golf course. Work was then undertaken on the Cat’s Claw Creeper.
As countries around the world move to restrict the use of herbicides like glyphosate in public places, Coastcare has continued to advocate a better way forward for tackling weeds on Coochiemudlo Island. We have compiled a list of resources to assist better understanding of the issue.
