Native to tropical America, miconia is a small tree with large leaves. Queensland has 3 species of miconia, all of which pose a significant threat to local rainforests. Miconia calvescens has also been found at nurseries in northern New South Wales.

Miconia is targeted for eradication in Queensland.

Miconia is a restricted invasive plant under the Biosecurity Act 2014.

How it is spread

  • Spread by birds, vehicles, machinery, footwear and animals.


  • Miconia is the 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.

Biological control

  • No known biological control agents.

Legal requirements

  • Miconia is a restricted invasive plant under the Biosecurity Act 2014. The Act requires that all sightings of limnocharis plants must be reported to Biosecurity Queensland within 24 hours of being found. By law, everyone has a general biosecurity obligation (GBO) to take all reasonable and practical steps to minimise the risk of spread of limnocharis 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.
  • At a local level, each local government must have a biosecurity plan that covers invasive plants and animals in its area. This plan may include actions to be taken on certain species. Some of these actions may be required under local laws. Contact your local government for more information.
