High Risk Traits:
- Other Eucalyptus species are invasive
- Reproduces by wind-dispersed seeds
- Possesses a lignotuber and coppices after cutting
Low Risk Traits:
- No reports of invasiveness or naturalization, but limited evidence of introduction outside native range
- Cultivated in full sun (dense shade may limit ability to spread)
- Unarmed (no spines, thorns, or burrs)
- Not reported to spread vegetatively
