Condor Lakes Salvinia Pest Management
Case study type
Since the early 2000s (and even at times in the 1990s) bio-control has been periodically added to the site (a 900m x 70m U-shaped lagoon) with periodic spraying. Bio-control was undertaken to reduce and/or remove weed species to improve water quality and reduce the spread of pest species.
In 2009 a works and outcomes harvester was used to break rafts (70% coverage), and several large amounts of bio-control were added in the upper reaches.
In 2013 and 2014 a harvester was used to remove the bulk of salvinia, with follow up spraying. The salvinia is now under control, with only approximately 3% now in evidence.
This project will reduce and/or remove weed species to improve water quality and reduce the spread of pest species at a lagoon at Condor Lakes.
True integrated pest control techniques were the most efficient.
Introduced red water lily is still growing profusely in the lagoon, possibly because of silting reducing depth.
