It is a very troublesome invasive species in northern Queensland in Australia and Sri Lanka, where it grows in estuaries and chokes mangrove swamps. The "A. glabra" tree was introduced to North Queensland sometime around 1912 as both a rootstock for similar Annona species such as "Annona atemoya", the custard apple. "A. glabra" seedlings carpet the banks and prevent other species from germinating or thriving. It also affects farms as it grows along fencelines and farm drains. It also invades and transforms undisturbed areas. This can be observed in the case of Australia’s Eubenangee Swamp National Park where an outbreak occurred due to poor wetland management.
