The Problem with Rubber Vine
Rubber vine is a vigorous climber which can grow either as a many stemmed shrub 1-2 meters in height, or scrambling up to 30 meters in trees. It was introduced into Australia as an ornamental shrub during the 1800s. Rubber vine spreads through seeds borne by water or wind. It invades riparian vegetation along waterways hillsides and pastures and is poisonous to stock if eaten.
Rubber Vine is a Weed Of National Significance and is also Restricted Matter – Category 3 under the Biosecurity Act 2014. This means that it cannot be distributed or disposed of in any way.
