Territory and Municipal Services have begun work to free Jerrabomberra Creek from the clutches of an invasive willow.

“The ACT Government has committed $55,000 toward the control of exotic and invasive weed species along Jerrabomberra Creek and to revegetate the area with native species,” said Warren Nicholls, Chair of the Jerrabomberra Wetlands Board of Management. “The work complements the ACT Government’s existing Waterways Restoration Program which aims to improve the health of the ACT’s river systems.

“Jerrabomberra Creek is currently dominated by Crack Willow, a highly invasive Weed of National Significance, and Black Alder, a declared pest plant. These weed species are among the worst in Australia due to their invasiveness, potential for spread and economic impacts.

“Work has now commenced to poison willows and alders using recognised control techniques. Once the trees have died – approximately six weeks after poisoning – they will be felled and removed. One or two trees may be left as standing dead timber for water birds such as darters to roost on.

“Following removal, Jerrabomberra Creek will be planted with common reed seedlings. Reed beds are a natural vegetation community in Australian wetlands that will stabilise the shoreline and help create habitat. Replanting is scheduled to take place during spring 2013.”
