       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)

 Total prioritisation score


Table 2 Prioritisation methodology (Methodology source: Gold Coast City Council Biosecurity Plan).
The invasive species, with their prioritisation score, are is 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 should they be recorded in Noosa immediate resources will be required,
proportional to the risk.
