Native to the Americas, mikania vine is a multi-stemmed perennial creeper and climber. It rapidly chokes and smothers areas it has colonised.
Mikania vine is a serious weed in West Africa, India, South-East Asia, Indonesia and the Pacific Islands. In Australia, it has been found in north Queensland. Suitable growing conditions for mikania also exist in eastern Queensland, north-eastern New South Wales, northern Western Australia, and coastal regions of the Northern Territory.
Mikania vine is a restricted invasive plant under the Biosecurity Act 2014.

How it is spread
- Reproduces by seed and vegetatively.
- Produces large quantities of seed (40,000 seeds per plant per year) that can be transported by wind, water, machinery or animals.
- Young shoots easily transported by flood or machinery; small plant fragments containing a node readily produce roots when in contact with moist soil.
- Target of a national eradication program.
- New infestations must:
- be reported to Biosecurity Queensland on 13 25 23
- be identified and removed by approved officers
- have their locations recorded prior to removal.
- No known biological control agents.
- This is a restricted invasive plant under the Biosecurity Act 2014. All other Mikania species are prohibited invasive plants.
- All sightings of mikania vine must be reported to Biosecurity Queensland within 24 hours of the sighting.
- By law, everyone has a general biosecurity obligation (GBO) to take all reasonable and practical steps to minimise the risk of spread of the plant until they receive advice from an authorised officer.
- It must not be kept, moved, given away, sold, or released into the environment without a permit.
