Weeds are a serious threat to Australia's environment and primary industries.
Gamba grass (Andropogon gayanus), cat’s claw creeper (Dolichandra unguis-cati) and Madeira vine (Anredera cordifolia) are declared Weeds of National Significance (WoNS) for their invasiveness and potential for spread. They are just a few of the many weeds threatening Australia’s environmental and agricultural areas.
Gamba grass has invaded tropical savannas across northern Australia. Its seeds are easily transported by wind, water, contaminated vehicles, machinery and even hay. Gamba grass fires burn up to 8 times most intensely and move twice as fast as other grass fires.
Invasive vines, such as cat’s claw creeper and Madeira vine, have dominated many ecosystems nation-wide that provide suitable climbing structures. These ecosystems include: floodplain and other forests, open woodlands and urban parklands and coastal dune scrub. Invasive vines can impact the overall structure and function of natural communities and restrict wildlife and human access.
To support landholders to manage these invasive weeds, two new national best practice manuals for gamba grass and invasive vines are now available for free download.
These manuals have been designed to aid in decision making about weed management, backed by the latest research and reviews by technical experts.
The manuals assist with identification, prioritising areas for control, developing management plans, choosing a control method and showcasing what other land managers are doing about these weeds.
These manuals were funded by the Australian Government through the Established Pest Animals and Weeds Management Pipeline Program and produced by Wild Matters Pty Ltd.
Best practice management manuals for all Weeds of National Significance are available from Weeds Australia.
