Synonyms: Acacia bracteata; Acacia cyanophylla; Acacia lindleyi; Mimosa saligna; Racosperma salignum

Wikipedia Abstract

Acacia saligna, commonly known by various names including coojong, golden wreath wattle, orange wattle, blue-leafed wattle, Western Australian golden wattle, and, in Africa, Port Jackson willow, is a small tree in the family Fabaceae. Native to Australia, it is widely distributed throughout the south west corner of Western Australia, extending north as far as the Murchison River, and east to Israelite Bay.

Invasive Species

Due it its many uses Acacia saligna, or the Port Jackson willow, has been globally distributed with up to 300 000 ha planted worldwide and was identified as one of three priority multipurpose species for arid and semi-arid zones by FAO’s Silvae Mediterranea Network in 1996. Native to Western Australia and suited to a wide range of enviromental conditions, it is a fast growing tree utilised for soil stabilisation, animal fodder, tannin production, windbreaks, ornamental use and as a source of fuel wood. In areas where it has become invasive A. saligna can have a wide range of negative effects on native biodiversity and ecosystems and is difficult to control due to its coppicing ability and the creation of large soil seed-banks.

Usage [2]  A yellow dye is obtained from the flowers; A green dye is obtained from the seed pods; On a 10% moisture basis, the bark contains 21.5% tannin; A fast growing plant, it is used for reclaiming eroded hillsides and wastelands and for stabilizing drift sands as well as for fuel. This is one of the best woody species for binding moving sand. It is useful for windbreaks, amenity plantings, beautification projects, and roadside stabilization in semiarid regions; Plants are heavily armed with thorns and make a good screen or hedge in warm temperate areas;
