Resources for tackling weeds in Tasmania
There are many weeds in Tasmania, and a wide range of methods for controlling and eradicating them have been tried, studied and implemented. Many Landcare Tasmania groups are dedicated to managing and eradicating weeds across the state.
Here are some links to resources for helping tackle these pesky plants (click on the headings for links):

Biological Control of Weeds in Australia
There are over 270 biocontrol for 60 weed species in Australia. Australia’s national science agency, CSIRO, has been developing biological controls since the 1920's. Biocontrol involve introducing co-evolved ‘natural enemies’ of a target weed to reduce its density to a level that is acceptable and that will maintain the weed at that acceptable level over time. Extensive testing over many years takes place to ensure biocontrol agents are be host-specific and don't damage any native or other important plant species. Landcare groups in Tasmania have been involved in community releases of biocontrols for African Boxthorn, Sea Spurge and Gorse.
