The bush is similar to the Black Wattle. Common names include cooba, native willow, willow wattle, Broughton willow,Sally wattle and black wattle. The main threats to this ecosystem are from invasive alien plants, especially black wattle trees. Wattles are also relatively common including northern black wattle and lancewood (northern golden wattle). Common names recorded include golden wattle, green wattle, black wattle, and broad-leaved wattle. Black wattle flowers provide very nitrogen rich pollen with no nectar. Black wattle is grown in plantations in South Africa and South America. Common names include black wattle, hickory wattle, mangium, and forest mangrove. Mill processed black wattle bark in colonial times and is now a combined museum. "A. decurrens" (tan wattle), "A. dealbata" (silver wattle) and "A. mearnsii" (black wattle). Some black wattle plantations were maintained for the leather industry, as their bark yielded tannin. As a result, the November-flowering black wattle ("Acacia mearnsii") was substituted for the regatta.
