Chemical-free weeding to restore Coochiemudlo Island’s Melaleuca Wetlands

Healthy Land and Water, Coochiemudlo Island Coastcare and Redland City Council will be working together over the next four years to control weeds within the Coochiemudlo Island Melaleuca Wetlands, as part of the Healthy Land and Water Moreton Bay Ramsar Wetland Project.

The Coochiemudlo Island Wetland Weed Control Project – Protecting Threatened Species and Restoring Ramsar values, was launched on Saturday 1st February with a working bee in the Melaleuca Wetlands, in celebration of World Wetlands Day. World Wetlands Day celebrates wetlands listed under the Convention on Wetlands of International Importance (Ramsar Convention) which includes the Moreton Bay Ramsar Wetland.

The Coochiemudlo Island Project will employ innovative chemical-free weeding techniques including saturated steam and hand removal methods to remove a range of weeds from the wetlands. Avoiding the use of chemicals prevents them from leaching through the sandy soils of the Island and subsequently into the groundwater and Moreton Bay. Weeds that will be targeted through this initiative include Singapore daisy, cocos palms, fishbone fern, asparagus fern, cassia, pepper and umbrella trees.

The project will help to reduce threats and restore habitat in and around the 19-hectare freshwater wetlands, which forms part of the Moreton Bay Ramsar site. The wetlands are of high cultural and ecological value and are home to more than 170 recorded native plant species including endangered orchids and fungi. The wetlands also provide habitat to more than 100 bird species, native animals and invertebrates.

“Healthy Land and Water is proud to support a project that endeavours to improve the health of the Melaleuca Wetlands and subsequently the Moreton Bay Ramsar Wetland. Wetlands play an important role in providing habitat, protecting our shores from erosion, absorbing pollutants and improving water quality,” said Julie McLellan, CEO of Healthy Land and Water.

Melaleuca wetland ecosystems have been diminished in south-east Queensland as a result of land clearing and coastal development pressures. The preservation of these wetlands are important not only for the ecosystem services it provides to the Island and the Moreton Bay Ramsar Wetland, but also as a remnant of this vegetation type in the region.

“The Australian Government is pleased to be able to support a project that applies a chemical free weeding approach to these delicate and ecologically diverse Melaleuca Wetlands and that helps improve the Moreton Bay Ramsar Wetland,” said Andrew Laming, Federal Member for Bowman.

According to Lance Hewlett the Deputy Mayor of Redland City Council and local divisional Councillor, “it is encouraging to see how Natural Resource Management organisations, local government, community groups and volunteers can work together to make a significant impact to help restore and protect the natural environment. I am thrilled to see that this project will not employ the use of potentially toxic, harmful chemicals, which in my opinion, is a subject for which the broader community has increasing concern,” he said.

Kim Richards, Member of Parliament for Redland, said it is encouraging to see how dedicated volunteers are in their efforts to protect the wetlands and. “The partnerships forged by Coastcare, Healthy Land and Water, and all levels of government will ensure we work together to protect and preserve the unique coastal environments of Coochiemudlo Island,” she said.

Coochiemudlo Island Coastcare has been caring for the Island’s environment since 2013 and its 175 members are passionate about undertaking ecosystem protection and restoration activities without the use of chemicals.

This project is supported by Healthy Land and Water, through funding from the Australian Government’s National Landcare Program.
