Coastal wattle

Coastal wattle (Acacia cyclops) is a dense, fast-growing shrub in the family Fabaceae, native to the southwestern and southern coastal regions of Western Australia, from Shark Bay south to the Nullarbor Plain. It grows on coastal dunes, sandy scrubland, and limestone substrates near the sea, where it tolerates salt spray, wind, and summer drought. Coastal wattle produces distinctive circular seeds with bright red arillate coatings, making them highly attractive to birds. Although valued in its native range for coastal stabilisation and revegetation, the species has become highly invasive in southern Africa, particularly South Africa, where it was introduced for dune stabilisation in the 19th century and has since spread extensively across the Cape Floristic Region, displacing native fynbos vegetation. It is listed among the 100 worst invasive species globally by the IUCN Invasive Species Specialist Group. In Australia, it is assessed as Least Concern. Management of invasive populations in South Africa involves mechanical removal and biological control efforts aimed at protecting the critically threatened fynbos biome.
