Fight to keep weed out of Wakatipu
A new group has been formed to keep the invasive weed lagarosiphon out of Lake Wakatipu as it spreads up the Kawarau River.
Land Information NZ biosecurity manager Dave Mole said the weed had been in the upper Kawarau River since 2008 but had slowly taken over a larger area and was now at the Kawarau Falls Bridge, near Frankton.
‘‘We’re taking action on that because the risk is getting incredibly high. We need to control it,’’ he said.
‘‘If we let the weed creep into the lake it will establish quickly, having an economic impact and threatening recreational activities such as fishing, swimming, water-skiing and jet-boating.’’
Control work was already underway to mitigate the risk of weed transfer from the infestation in the Kawarau River.
However, LINZ had developed a formal weed management group with local councils and private operators to keep Lake Wakatipu free of the weed, he said.
There would also be a public awareness programme run to hopefully stop the transfer of lagarosiphon from other water bodies.
