About the guide

Mesquite is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts. There are four species and several hybrids of Prosopis, which are all collectively known as mesquite.

Mesquite's economic impacts stem from its habit of forming dense, impenetrable thickets which, combined with its large thorns, prevent stock accessing watering holes and make mustering difficult. Mesquite also reduces the productivity of pastoral country by taking over grasslands and using valuable water resources. Other nuisances from mesquite include damage to animal hooves and vehicle tyres from thorns, and the poisoning of livestock which consume excessive amounts of seed pods.

Environmental impacts include land erosion resulting from the loss of grassland habitat that supports native plants and animals; and the provision of safe refuges for feral animals such as pigs and cats.

This management guide was prepared in 2003. The state and territory contacts in this document may be out of date.
