Warmer days, shallow and still waters combine to promote the spread of Salvinia at this time of year.

Salvinia is a major aquatic weed threatening waterways in SE Queensland. It is considered one of the worst water weeds in Australia due to its invasiveness and potential for spread.

The summer months are peak season for mosquito and midge breeding activity in SE Queensland. New developments, parks and construction projects near mangrove and inter-tidal zones including estuaries and canals are prime habitat, with increased activity during wet weather and tidal influences.
