2020-02-11 P&E Agenda - Item 5 - Attachment 2 - Draft Noosa Biosecurity Plan 2020

The options for management of invasive plants is changing all the time with new products and
technologies coming onto the market, with the aim of addressing shortcomings of existing
techniques, and tackling emerging threats. Council has, and will continue to, trial new technologies
as they become available, assessing them for efficacy, safety, cost effectiveness, and potential off-
target impact.

5.1.3        Timing
To maximise management effectiveness different invasive species are controlled at different times.
For example certain plant species may best be controlled during growth stages or prior to flowering.
Table 5 below depicts the seasonal nature of managing invasive plant species.

 Leucaena leucocephala is a fodder tree that has the potential to invade bushland in Noosa Shire. Although
    not a scheduled species under the Biosecurity Act 2014 landowners are encouraged to remove new
                               incursions from their land. Photo: Qld DAF
