Stage one
Identify priority species, populations or ecological communities at risk near the weed infestations. Remove the weeds causing direct threats to provide short term protection.Stage two
An expansion of stage one, covering a larger area of infestation. Weed removal should be prioritised to suitable habitat areas for the species, population or ecological community at risk, so these may expand in the future. Follow up control of weed seedlings in all stage one areas should also occur in stage two.Stage three
Further expansion of earlier stages, with the aim of removing all the specified weed or weeds from the site and surrounding areas to prevent re-invasion. This stage also includes the follow up control of weed seedlings in all previously controlled stage one and stage two areas.
See the Bitou bush and boneseed threat abatement plan: Invasion of native plant communities by Chrysanthemoides monilifera (bitou bush and boneseed) chapter 7, for an example of a staged approach to weed control.
