The species has become a serious environmental weed in Australia on disturbed land along watercourses and in the wet tropics where it smothers other vegetation.

They have a cosmopolitan distribution in the worlds wet tropics, being found in the Americas, Africa and Asia.

They are both in the 'wet' tropics: no shortage of moisture, light, or heat, and no interruptions by winter.

Principal agricultural activity is sugar cane farming in the wet tropics and cattle grazing in the dry tropics regions.

These species are cosmopolitan, but the stinkhorns and their allies are most diverse in the wet tropics.

However, the technical difficulties of operating in the wet tropics dogged the project.

Many heavily weathered or oxidized soils, especially in the wet tropics, have a high concentration of Al.

It supports almost all the high altitude rainforest bird species endemic to Australia's wet tropics, and could serve as an important climate change refuge.

Fossils of leaves help reveal the altitude of the mountains, rising from the wet tropics up above the cold tree line.

It consists of only one species Palaeopsyche melanias, which is found in the wet tropics of Queensland.
