A few weeks ago we welcomed 18.6mm of rain, but with warm conditions following, we've had a huge outbreak of Noogoora Burr (Xanthium strumarium) and other nasty weeds in one of our priority restoration sites, we call the "flood-out".
Fortunately we were able to respond at the right time, with the necessary resources to manage these weeds, enabling our native species the chance to return to this previously disturbed area.
Thankfully we had the appropriate resources: ute, mounted spray units, access to colleagues (Jeroen van Veen from Victoria, thank-you), ability to acquire chemicals and protective clothing, functioning safety systems and technology to enable accurate measuring and monitoring of our efforts.
The extent of the weeds covers an area of over 50 hectares and as you can see from the photographs in parts it's very dense, and in other areas, disbursed under native vegetation.
Every plant has the ability to produce thousands of seeds, and if disbursed can stay dormant in the landscape for many years, just waiting for the perfect combination of environmental factors to release and germinate.
Active management of our reserves is the key to continually improving the environmental health of these areas, and with ongoing support we're able to respond as required to these and other threatening processes.
The job is not finished – only 80% has received the first round of treatment and all requires follow up over the next month. Back to spraying for me!
