Summary

This project will:
  • control pest species to improve water quality
  • reduce the spread of pest species.

Since the 1990s, there have been periodic outbreaks of salvinia, which has been sprayed as required. The most recent outbreak was in 2013.

Benefits

This project will control pest species to improve water quality and reduce the spread of pest species at Alexander Lakes.

Lesson

Residents are mainly concerned with the occasional outbreaks of red azolla, algae blooms and Mexican yellow water lily (sprayed when it reaches more than 50% coverage near outflows).
The increase in floating water plants (red azolla, duck weed etc.) is most likely due to the nutrient load from roosting birds on islands and current cyclic climatic conditions. It is sometimes difficult to explain to residents that this occurs in cycles.
