Acacia saligna, known as orange wattle, is native to parts of Oceania. It has been introduced to various continents including parts of Africa, Asia, the Americas, and Europe, adapting to different regions. In certain areas of the Mediterranean, South America, Africa, and Oceania, orange wattle is sometimes thought to be invasive and may have an impact on local ecosystems. Its ability to thrive in a range of habitats has contributed to its wide cultivation and naturalization beyond its native range.

Orange wattle is an adaptable, fast-growing tree that has a number of useful applications - it is cultivated as a decorative plant, animal fodder, for firewood, soil bioremediation, and revegetation. However, orange wattle is also considered an invasive species in some areas.

Physical removal of established orange wattle can be very time-consuming due to its large and persistent soil seed banks. Reducing these seed banks is one of the key aspects of orange wattle control. This can be achieved by soil solarization, or controlled, slow, but intense burning. Unwanted mature plants should be cut down entirely, and herbicides applied to the stumps to prevent regeneration and new sprouts. There are certain biological control agents that can be effective against this invasive plant, like Uromycladium tepperianum, a fungus that reduces density, longevity and reproductive capacity of orange wattle, and Melanterius compactus, a seed-feeding weevil that can significantly reduce its soil seed bank. If you opt for chemical control, please consult an agricultural expert to determine which active substance is the best for your geographical region. Read the manufacturer's instructions on the product label and follow them carefully. Do not spray on a windy day to avoid drift and harmful effects on non-target species.
