Understanding the impacts willow saw fly is having on willow populations in Australia is important as it can help guide future policy and willow managment practices.
If it turns out that sawfly continues to cause die back, will this reduce the spread of willows long term and eliminate the need for control programs for certain types of willows or in certain cicumstances? Will the die back allow native veg to survive and thrive under willows and eventually out compete them? Will there be a short term problem with a lot of dead willow debris in streams and rivers resulting from the die back?
The Victorian DPI has been funding Fiona Ede since to 2006 to research the impact of willow saw fly. As there have been no reported willow deaths in a period of drought and so willows are being stressed by lacck of water and saw fly but these had been willow die back of trunks and the willows re-shooting from the base. the major concent thata willows would be extensive deaths resulting is stream distabilisation has not occurred and so Fionas researcch has moved on to looking at the impacts and implications. Here are links to Fiona's Reports
