Invasive Species

Tecoma stans is a South American tree which has been introduced to other tropical and subtropical regions (Indian Ocean, Pacific, Australia) as an ornamental. Tecoma stans prefers dry and disturbed areas such as roadsides but it can also be found in relatively undisturbed forests. It can develop dense, almost monospecific thickets and restrict the regeneration of native species.
