This weed has the ability to spread rapidly and smother native vegetation and crops. If it becomes established in Australia, mikania vine will damage the natural environment and affect the habitat of native animals. Mikania vine thrives in open areas as well as in partial shade and disturbed areas. It will also grow in deep shade although it is unlikely to flower in these areas. It can, however, grow up through a closed forest and become canopy emergent. Mikania vine also has the potential to cause serious damage to agricultural industries (including sugar cane, tropical fruit and vegetable production) in the tropics. When mixed with the soil, mikania vine debris produces toxins that inhibit growth of vegetation.

Mikania was first detected in Australia in 1998. It is a rapidly growing, scrambling perennial vine with many branches. It is a major environmental weed that has the potential to rapidly spread across the Queensland Wet Tropics and other humid regions of northern Australia with serious consequences. Potential distribution in Australia includes the coastal regions of the Northern Territory, northern Western Australia, north-eastern New South Wales and much of eastern Queensland, posing a major threat to the Wet Tropics World Heritage areas in Queensland.
