To help fight SEQ’s battle with invasive weed species, Healthy Land and Water teamed up with Seqwater in 2016 to deliver the Riparian Weed Control program.
The targeted weed management program was developed to reduce and control the impact caused by the cat’s claw creeper on deep rooted native vegetation in six priority water supply catchments in SEQ.
The treated catchments included, Stanley River, Buaraba Creek, Mid Brisbane River, Lower Lockyer Creek and Northbrook.
Following the completion of the program in 2018, the volume of the vine reduced significantly within the treated areas.
Eradication of the creeper ensures the long-term sustainable delivery of cleaner water to water treatment facilities through the ecological services provided by the now healthier and recovering native vegetation.
The major success of the project led to the implementation of the Regional Weed Control Program as an extension of the Riparian Weed Control Program.
The Regional Weed Control Program, running from 2018 to 2023, builds on the success of the Riparian Weed Control Program. The objectives of the partnership program between Seqwater and Healthy Land and Water, include managing and reducing invasive weed species like the creeper, Madeira vine and the Chinese cletis.
The program encompasses a broader variety of catchments than the Riparian Weed Control Program and includes additions such as the Mount Crosby area in the more central SEQ region, Cedar Grove, Kalbar, Kooralbyn, Canungra and Rathdowney, along the southern end of the Logan River.
The cat’s claw creeper and Madeira vine are the primary weeds targeted by this program, however the Chinese celtis is a prominent feature close to the Mount Crosby water treatment facility and will also be targeted.
In contrast to previous management efforts, which relied heavily on physical and chemical management of weeds, the Regional Weed Control Program will focus on the rearing and release of biological control agents. In addition to the widespread establishment of agents, the long-term objective is to develop the ability to continue the raising and release of agents beyond the initial phase of this partnership program scheduled to end in 2023.
