Acacia farnesiana (L.) Willd. -A Potentially Invasive Alien Species?

Arnobio M.B. Cavalcante, Robert D. Cox


Acacia farnesiana (L.) Willd. is a small tree that has become a severe pest on rangelands of  Brazil, USA and other countries because it is expanding in density and range and is difficult to control. This study characterizes the current and potential distribution of Acacia farnesiana in the world by utilizing published literature and online databases. The study suggests a future of continued expansion, given its current range. This information should enhance the ability of landowners and managers around the world to prevent Acacia farnesiana invasion, thereby increasing favorable conditions for livestock and wildlife.
