How does this weed affect you?

Alligator weed is a potentially devastating weed that grows in water and on land, affecting both waterways and floodplain areas.

It has extremely vigorous growth and great tolerance of normal control measures, which makes it a major threat to wetlands, rivers and irrigation systems.

Alligator weed is considered one of the world's worst weeds because it affects both aquatic and terrestrial environments. Overseas experience indicates that its potential impacts in Australia could be devastating.
