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) and other Woody weeds like Acers and Tree of Heaven. Between 2009 and 2011 the project focused on the section of the Wollondilly between the Wingecarribee Junction and Goodmans Ford. In January 2015 we helped National Parks with a weed mapping project between Goodmans Ford and Burnt flat so that Contracators could quote and run a project treating Crack Willows on NPWS estate, crown river bed and private land, where the owners gave consent, downstream of Tomat Creek. In October 2016 we did a second trip this time mapping willows and other woody weeds down to the stored water of Lake Burragorang and in April 2017 we dida trip to start the treatment of the Tree of Heaven sites found downstream of Goodmans Ford and also to monitoring the control work downstream of Tomat Creek.

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. this also allowed us to consolidate the work done by us and the Wingecarribee Council and Bushcare community to extend from Berima Weir down to the Wollondilly and then down to the stored water of Lake Burragorang

If consent can be obtained this protect will continue the treatment downstream of Goodmans Ford to the stpred water.
