    What’s the problem with weed vines?

    Cats Claw Creeper and Madeira Vine smother native vegetation, particularly along streams. This usually destroys

    both large and small trees, and causes their collapse into waterways. As a result, there is a loss of habitat for both

    our forest-dwelling wildlife and those living in the streams.

    Landholders are also faced with erosion problems, and water quality is seriously degraded by sediment. For this

    reason, these two vines are listed as Weeds of National Significance.

    They are a serious threat to the survival of Subtropical Lowland Rainforest which is critically endangered nationally.

    This rainforest is facing an extremely high risk of extinction. Many threatened animals such as the Giant Barred Frog,

    Mary River Turtle and Australian Lungfish, are also affected by the damage caused to their habitat.

    A third weed vine, Dutchman’s Pipe, is a problem for the threatened Richmond Birdwing Butterfly. The vine mimics

    the native vine on which the butterfly lays its eggs. Unfortunately, the weed vine is toxic to the caterpillars and

    destroys them before they can pupate.

    Where are these weed vines?

    These weed vines occur in eastern Australia and they are particularly prolific between Sydney and Rockhampton.

    The focus of our work to eradicate weed vines is the Upper Mary River catchment, which includes tributaries arising

    in the Blackall and Conondale ranges, downstream on the main trunk of the river to Cambroon. Cats Claw Creeper,

    Madeira Vine and Dutchman’s Pipe occur through much of this catchment but our control works are gradually

    reducing their extent. Work began at the top of the catchment to prevent seed and tubers being carried

    downstream and continuing to infest the lower reaches of the Mary River.

  • How do we control these weeds?

    Hinterland Bush Links has mapped most infestations over the past eight years, with community reports adding to the

    records. We have then engaged licensed contractors to destroy these weed vines. Permits are required for use of all


    Cats Claw Creeper

    With Cats Claw Creeper, a section of vines is cut from chest height to the base of the tree so that the vine is killed in

    the canopy. This prevents the vine flowering and dispersing seed from the long hanging pods. The cut stems at the

    base of the tree are then treated with Glyphosate, Brush-off or Kamba to kill tubers underground. This is repeated at

    least once a year for up to five years to ensure that all tubers are killed and can’t re-sprout. Foliar spraying is

    sometimes used on small vines that have spread across the ground, but this isn’t always effective. (See Resources

    below for more information)

    Biocontrols have been released at some sites to control the growth of Cats Claw Creeper. The Leaf-mining Jewel

    Beetle and the Tingid Bug are insects that have had some impact on the vines.

  • Madeira Vine

    Madeira Vine is never pulled out of the trees as it is covered with loosely attached aerial tubers, each of which

    sprouts a new vine if it is shaken to the ground. Instead, the lower stems close to the base of the tree, are scraped of

    bark on two sides for a length of about 30cm. Then Vigilant herbicide is applied on these scraped surfaces and this is

    carried both up the stem and underground to the aerial and ground tubers. Never cut the vine as this will prevent

    movement of the herbicide to the aerial tubers. Spraying is sometimes undertaken with Brush-off or Starane. (See

    Resources for more information). Infestations of Madeira Vine are re-treated at least once a year for up to ten years

    to kill all aerial and underground tubers.

  • Dutchman’s Pipe

    Dutchman’s pipe is becoming more prevalent in the Upper Mary Catchment. It has an abundance of seed which

    seems to be dispersing via water, animals and humans. Unopened seed pods on smaller infestations should be

    collected and disposed of where possible. Single plants can be dug out although care should be taken to remove the

    entire crown and as much root as possible. For larger infestations stems can be cut and painted or stem scraped.

    Vigilant gel is effective in both these treatments or Glyphosate at 1:1 can be used. For larger infestations foliage is

    sprayed after ensuring no native trees are under the vines. Glyphosate and/or Metsulfuron (Brush-off) can be used.

    Roving Restorers

    Hinterland Bush Links has a volunteer bush regeneration group called Roving Restorers which assists landholders

    with weed control including treating light infestations of these serious weed vines. Bush Links also supports the

    Sunshine Coast Council’s Little Yabba, Avocado Lane and Maleny Showgrounds Bushcare groups which do similar

    work on Council reserves.

  • How you can help with control?

    First up, you need to recognise these weed vines. Have a look at the photos in this information pack to help you

    identify the vines, even when they are not flowering.

    A simple approach to Cats Claw control is to cut the stems low on the trunk before flowering so that they don’t set

    seed. You can then request help through our program to do further treatment of the vines.

    Hinterland Bush Links would like to receive reports of all infestations in the Upper Mary Catchment. Once we know

    the location and extent of these weed sites, we can schedule them in for treatment. Please let Susie Duncan know by

    phone or email – see details below.

    If you are keen to undertake herbicide treatment of any of these vines yourself, refer to the techniques described in

    these notes and fact sheets. Make sure you follow all herbicide labelling for correct dilutions and safety measures.

    Note that you will need to repeat the treatment at least once a year for up to five years (Cats Claw), and ten years

    (Madeira Vine), to ensure that underground tubers are destroyed. Please contact us for further advice and to report

    the location of the site.

    Sunshine Coast Council offer Landholder Environment Grants (LEG) once a year Landholder Environment Grants so

    you may be able to receive some funding to assist with weed vine works you undertake. Talking to your neighbours

    about weed vine issues and how to get in touch with this program, would greatly assist our eradication work. You

    may also consider planting Richmond Birdwing Vines in semi-shaded sites to increase habitat for the Richmond

    Birdwing Butterfly. These vines are available from the Barung Landcare nursery in Porters Lane, Maleny.
