Staged approach to weed control

We use a staged approach to identify, prioritise and control invasive weeds and to protect native species.

When managing weeds, dense and/or widespread weed infestations will likely require multiple control events. Additionally, actions to protect biodiversity assets at the site must be occur together with weed control. A staged approach to weed control can be used to develop control strategies or site plans to achieve effective control and biodiversity protection outcomes.

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.

Invasion of native plant communities by Chrysanthemoides monilifera (bitou bush and boneseed)

Since the arrival of Chrysanthemoides monilifera subsp. rotundata (bitou bush) from South Africa in 1908, this highly invasive shrub has spread to occupy approximately 80% of coastal New South Wales. It now poses the single greatest threat to NSW coastal ecosystems and coastal biodiversity, especially along the north coast.
