About the guide
Pond apple is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts. Introduced as grafting stock for the closely related custard apple, it is a very hardy tree and an aggressive invader. Over time the dense thickets it forms can gradually replace everything else in the canopy and create an undesirable new habitat.
Its ability to grow in flooded areas and to tolerate salt water has enabled it to spread through much of northern Queensland's wet tropics area. It now infests more than 2000 ha of the Wet Tropics Bioregion, and threatens melaleuca wetlands and native mangrove communities.
While pond apple is considered an environmental weed, its commercial impacts are also increasing as it spreads. It is now threatening the cane and cattle industries by growing in and along creeks, fencelines and farm drains. Unlike many weeds, it can invade and transform undisturbed areas.
