Campbelltown City Council: Eradication of Frogbit from the Upper Georges River
In May 2019, Campbelltown City Council identified Frogbit (Limnobium laevigatum) in the upper Georges River. Frogbit is a biosecurity threat and is known for its fast growth and rapid spread. Over the past 15 months, Council has worked closely with project partners to plan, actively manage removal and undertake extensive surveillance to limit the further spread of the plant. The project has seen new methods trialled, strong collaboration and key learnings for project partners.  Surveillance will continue over the coming years to ensure total eradication.

Queanbeyan-Palerang Regional Council: Beefing up Braidwood
The Beefing up Braidwood project supports drought-affected farmers to manage weeds impacting the local grazing industry. High resolution (10cm) aerial photography was obtained over 420km2 of grazing land to assist weed management planning. More than 50 farms covering 150km2 were engaged and assistance provided to develop integrated weed management plans aligned to the regional weed plan. Very high (2cm) resolution drone photography was flown across 36km2 of targeted sites to enhance weed mapping and property weed management planning. An extensive weed control assistance program was then commenced to help implement the property plans.
