An infestation of the Creeping Burrhead water plant has recently been found and removed from the bed of Moggill Creek. This raises some concern that more infestations may be present in other locations, particularly below pools.
It quickly spreads via its creeping underwater stems and forms dense clumps that out-compete native species. Clumps or segments of the underwater stems can separate from each other and form new colonies.
