Noosa Council’s Parks and Natural Areas team, along with qualified contractors and the
Heritage Park Bushland group, currently treat the priority pest plant species (Table 4)
throughout a number of zones identified in the park’s BOA. Other weed species, such as
paragrass (Urochloa mutica) in the lagoon, are also recommended for control consistent
with shire-wide priorities. The riparian vegetation of Wooroi Creek plays an essential role
in maintaining water quality and reducing the transport of sediment into th Noosa River.
Ecological restoration activities follow best practice guidelines for erosion and sediment control.
Vegetation plantings are not to extend past bollards onto grassed recreation areas. (Section
3.5; Figure 4).

Salvinia (a Class 2 pest plant), occurs in one of the park’s lagoons. It is unknown how the
infestation occurred but it is possible there is an upstream source. A range of options are
available for ongoing management of salvinia, including (i) manual removal, (ii) biological
control using weevils and (iii) frog friendly herbicides. However no method provides complete
elimination of salvinia from a water body. In the past, Noosa Council has manually removed
salvinia from the park’s lagoon using nets, which cost Council $4,620 for one treatment. Under
the right conditions aquatic weeds can spread rapidly. Therefore to keep the volume of Salvinia
down, this practice would need to be repeated several times per year, particularly in spring
and summer (i.e. at a cost of $15,000 per year). There is also a risk of spreading salvinia
offsite from equipment and disposal sites. More recently Council has trialled biological control
