Weed Potential 
As a weed Madeira Vine is wide spread in coastal and adjoining regions in eastern and south eastern Australia. It grows in a variety of native habitats including woodlands, rainforests and along water courses or in disturbed or degraded land. 

The plant produces large tubers (foot ball size) that may be up to 1m (3ft) deep in the soil. Growth occurs during the warmer months and can exceed 1m (3ft) per week with thousands of aerial tubers produced along the stems. The aerial tubers remain viable for up to 10-years. 

The vine smothers ground vegetation and climbs into shrubs and trees forming a dense covering cutting out the light. The plant prefers a sunny to semi shaded moist position and the main form of reproduction is tubers but the seeds are also viable. The tubers are dispersed by water or in garden waste and established plants are hard to eradicate.

Control methods include physically digging out tubers which may be a difficult task as all parts must be removed. Aerial tubers can be cut from the plant but a tarpaulin should be placed at the base as the aerial tubers tend to fall when disturbed. 

All plant material should be removed off site and destroyed. Plants may also be stem-scraped and painted with a non-selective herbicide. This will kill the vine and the aerial tubers over several months. Follow up applications are required as the tubers often re-sprout.
