AbstractHygrophila costata is a perennial semi-aquatic plant listed as Category 3 Restricted Matter under the Biosecurity Act 2014, Queensland. It has been found growing in many creeks and rivers in Far North Queensland, where it is displacing native vegetation and colonizing/stabilizing otherwise transient sand banks. The impacts of H. costata are not yet fully understood but effects on hydrology and species composition are believed to be detrimental.
