Family: Fabaceae
High Risk Traits:
- Commonly cultivated and naturalized within Australia, outside natural range
- Listed as a weed of unspecified impacts in Australia (unconfirmed)
- Other Acacia species are invasive
- Tolerates many soil types
- N-Fixing (modifies soil chemistry)
- Reproduces by seeds
- Seeds dispersed by ants, possibly water and/or gravity and intentionally by people
- Seeds able to be stored for extended periods; May form a persistent seed bank
- Gaps in biological and ecological information may reduce accuracy of risk prediction
Low Risk Traits:
- Grows primarily in temperate to Mediterranean climates (may limit ability to spread to cooler, higher elevations of tropical/subtropical islands)
- Unarmed (no spines, thorns, or burrs)
- Ornamental
- Not reported to spread vegetatively
- Ant-dispersed seeds unlikely to be dispersed long distances without human assistance
