4. Management approach
The most cost effective approach is to prevent invasive species from establishing within the shire. If
invasive species are not detected early and eradicated, then costly long term management is
required.
Biosecurity Queensland, Noosa Council and landowners have been successful in eradicating
several potentially invasive species from the shire. For example Water mimosa (Neptunia oleracea),
Senegalia spp., Madras thorn (Pithecellobium dulce) and Parthenium (Parthenium hysterophorus)
were reported to Council by landowners and were eradicated through herbicide treatment and
mechanical removal. Without early detection, reporting and timely eradication, there would have
been potentially significant impacts for landowners and costly ongoing management.


4.1      Reporting and management response
Reports of invasive species are provided through Council surveillance programs or from members
of the public. The response from Council to landowners will depend on the species concerned and
whether they are a scheduled species under the Biosecurity Act 2014 (see Figure 1 below).

4.2      Shire wide priorities for Schedule 1 & 2 invasive species
To guide Council’s prioritised management of scheduled species an expert panel has assessed the
risk and management feasibility of Schedule 1 & 2 invasive species that have been recorded in
Noosa Shire previously. Note that all public and private landowners within Noosa Shire have a
biosecurity obligation for all Schedule 1 & 2 invasive matters regardless of the prioritisation score.
