Cumbungi control at Four Spring Lake

IFS staff cutting cumbungi

We monitored and completed follow up control of cumbungi infestation at Four Springs Lake. On Friday 24 January, we inspected the nine known cumbungi infestation sites. We found 20 stems in total at four sites. We cut the stems below the water as this has proven to be a successful control method. We surveyed the remainder of the lake with no new infestations detected.


We will undertake a further inspection in 2021 or sooner if any new infestations are reported.
