An aquatic weed believed to be salvinia molesta, which grew only along the shoreline in January, has multiplied so fast it now covers the entire surface of the water at Lakewood residential community, Pemulwuy, Australia.
The lake and its surrounds were home to an abundance of wildlife including ducks, pelicans and a pair of black swans, but that birdlife had thinned substantially since the weed coverage increased.
Due to unseasonably high temperatures has resulted in above-average water temperatures promoting the growth of the salvinia.
An aquatic weed harvester is being contracted to clear the lake of the invasive species and work is expected to last two weeks.
