5. Pressures on the Bushland Reserve
   Network
5.1     Invasive Species
The Noosa Biosecurity Plan 2019 has identified invasive
species, a large number of which have their origin as
garden escapees, and management actions across the
Shire. Similar to other areas of SEQ, a large number of
invasive plants are threatening biodiversity values and the
bushland reserve network, with those reserves in peri-
urban/urban areas generally more impacted from escaped
garden plants.

This plan has prioritised a number of key invasive plant
species that are considered to be “transformer weeds”.
These species have the capacity to alter and dominate
native vegetation strata, whether it be Cats Claw Creeper
(Dolichandra unguis–cati) destroying the canopy of
mature rainforest or Singapore Daisy (Sphagneticola
trilobata) dominating the ground strata and preventing
recruitment and establishment of native plants.

Figure 11 lists transformer weeds and their impact
potential. This list was developed by an Internal
Stakeholder Group based on their long-term local
operational experience in the Noosa area.

                                                                such as Ground Parrots (Pezoporus

of Noosa's bushland reserves and has its local origin as a
garden escapee
