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

The risk assessment was based on invasive species current extent, risk to biodiversity, economy
and people. The feasibility of control was also considered, with all Schedule 2 species given a
priority score. The prioritisation methodology considered;
     Likelihood of establishment (scored between 1 and 5, where 5 was the highest likelihood)
     Ecological impact (scored between 1 and 5, where 5 was the highest impact)
     Economic impact (scored between 1 and 5, where 5 was the highest impact)
     Community impact (scored between 1 and 5, where 5 was the highest impact)
     Feasibility of management actions (scored between 1 and 10, where 10 was the highest
      likelihood of success)
The invasive species, with their prioritisation score, are further categorised into priority management
responses of prevention, eradication or containment. This is depicted in the generalised invasion
curve below. Note that actual on-ground actions for landowners will depend on the extent of
infestation.

‘Prevention’ is the highest priority followed by ‘eradication’ and ‘containment’. Investment priorities
will mirror the results of the risk assessment. In most circumstances, Priority 1 species will require
little investment, but if they do show up in Noosa immediate resources will need to be allocated.
This plan also prioritises targeting biosecurity threats that have the best chance of being eradicated
(Priority 2: Eradication list) completely from Noosa. The Priority lists enables extra resources to be
targeted towards the next highest risk species – the more the investment, the more effective
eradication and containment will be, and the further down the list management actions will be
undertaken. It is hoped that improvements in technologies and techniques, along with active
management, may see some of the Priority 3: Containment threats able to move to potentially
eradicable in the future, or at least to achieve local eradications.
