The National Tropical Weeds Eradication Program targets five weed species native to tropical America that have been introduced into North Queensland:
- Limnocharis (Limnocharis flava)
- Mikania Vine (Mikania micrantha)
- Miconia (Miconia calvescens, racemosa, M. nervosa)
Limnocharis, miconia and mikania vine are all considered serious weeds in other countries, while Miconia nervosa and Miconia racemosa have exhibited invasive characteristics in North Queensland.
The program is managed by Biosecurity Queensland, a business unit of the Queensland Department of Agriculture and Fisheries. Funding for the program is shared nationally with contributions from the Australian, Queensland, New South Wales, Northern Territory and Western Australian governments.
The Red Witchweed National Eradication Program targets eradication of Striga asiatica, a parasitic plant which hosts on grasses, including sorghum, corn, sugar cane and various important pasture grasses.
The RWWNEP program is managed by Biosecurity Queensland, a business unit of the Department of Agriculture and Fisheries and jointly funded/supported by the Federal Government as well as state government agencies in Queensland, New South Wales and the Northern Territory plus Grain Industry Peak Bodies, Meat and Livestock Association and Canegrowers.
Hawkweeds, Hieracium species, are also the subject of eradication programs in NSW, Victoria and Tasmania.
