Wollondilly River - Lower Invasive Willow Control

The Lower Wollondilly invasive willow control project is mapping and, where we have consent, treating invasive willows including Black Willows, Grey Sallow Willows and Crack Willows). To-date the project has focused on the section of the Wollondilly between the Wingecarribee Junction and Goodmans Ford. Crack Willows have been included in the project as there were only a small number of crack willows in this section of river and most were small or medium size and so treating them now would prevent future spread and keep the amount of debris low. There are a few properties that did not give consent and so there are about a dozen willows upstream of Goodmans Ford plus the willows on the property at Goodmans Ford. The landowner at Goodmans Ford is monitoring the willows arround the ford for evidence of Willow Saw fly attack and the impact it is having on the willows. The river between Wollondilly Junction and Goodmans Ford is now in the monitoring phase and will be monitored biannually.

If consent can be obtained this protect will continue the treatment downstream of Goodmans Ford in the future where we also expect to find Black Willows. Willows in this section have been mapped by NPWS.

A willow mapping trip down to the Wingecarribee junction will also be carried out in the future when water levels allow for the river to be paddled.
