Wikipedia Abstract

Acacia confusa is a perennial tree native to South-East Asia. Some common names for it are Acacia Petit Feuille, Small Philippine Acacia, Formosa Acacia (Taiwan Acacia) and Formosan Koa. It grows to a height of 15m. The tree has become very common in many tropical Pacific areas, including Hawaii, where the species is considered invasive.

Invasive Species

Acacia confusa, a native of northern Philippines, has been introduced to many places throughout Asia and the Pacific. Being well suited to warm moist environments it has become invasive in many of the places of introduction, including Hawai‘i and the Northern Mariana Islands and shows potential to become invasive in others, including Micronesia and Palau. It would probably be wise not to introduce this species to islands where it is not already present.
