I'm wondering if Salvinia molesta is commonly known as water lettuce.
The Warrego River at the Cunnamulla Weir, which is 18 klms. long, was a
carpet of solid green vegetation for over 12 months. The D.N.R. was notified
by concerned landholders in October 1999. Nothing was done until December
2000 when a major flood from the North was coming down the river system.
Of course, by then it was far too late and 8 litre garden sprayers being
used by a few people to try and kill this dreadful ecological disastrous
weed, has to have been a case of "being seen to be doing something".
The flood has long gone from Cunnamulla, the water is still trickling over
the weir, which is just South of the town, and the dreaded weed is back, as
green as ever.
I'm wondering if the D.N.R. can come up with something better than waiting
for a major flood in the Murray-Darling system to eradicate this ecological
