Class 1 Prohibited invasive species in Florida. Another import from Australia, it is spread widely by seeds devoured by hordes of birds in season. The (also non-native) European Starlings feed in huge flocks on stands of Australian pine. The dense root system and thick carpet of shed needles smother all other plants in its vicinity.

It is also a weak tree, because of its shallow root system. It is easily blown down in high winds, and roads are often blocked and power lines taken down by these huge trees after tropical storms. If you have any on your property, take them down, especially if they are within range of any buildings. They make excellent firewood.
