5. Management methods
The method of management will depend on whether the purpose of invasive species control is to
prevent/mitigate threats to biodiversity, local economies or human health and also the extent of the
infestation.


5.1     Invasive plants
                         5.1.1       Property pest management plans
A property pest management plan can assist landowners where the extent of invasive species
requires management over several years. The nature of the property pest management plan will
depend on the desired outcomes, whether that be for example, improving agricultural productivity
or requiring ecological restoration. Private landowners my develop a property management plan as
a requirement under the Biosecurity Act 2014 or voluntarily through a Land for Wildlife or Nature
Refuge program where ecological restoration is the main objective.


 Case study: Bushland Operational Assessments (BOAs)

 Council uses a Bushland Operational Assessment (BOA) methodology to assess the condition
 of its bushland reserves. Essentially a BOA spatially identifies the resilience of native vegetation
 against various threats such as weeds, fire, disturbance and nutrients and its recovery potential.
 Condition classes range from ‘Excellent resilience’ where full recovery is expected after natural
 disturbance to ‘Nil resilience’ where significant reconstruction is required to bring the site back to
 a natural condition. The BOAs are reviewed every 5 years to assess how the condition of the
 bushland reserve has changed over time.

 ecological restoration works
