Summary

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.

Benefits

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.

Lesson

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.
