- Other Eucalyptus species are invasive
- Leaf leachates may be toxic to aquatic wildlife and possibly humans
- Tolerates many soil types
- Forms small, pure stands within native range
- Reproduces by seeds
- Hybridizes with other Eucalyptus species
- Capable of selfing (with reduced seed set)
- Seeds dispersed by wind and intentionally by people
- Coppices after cutting, but reported to be killed by fire
Low Risk Traits:
- Despite naturalization, no negative impacts described from introduced range
- Unarmed (no spines, thorns, or burrs)
- May be browsed by animals
- Thrives in full sun (dense shade may limit ability to establish and spread)
- Not reported to spread vegetatively
- Limited seed set
- Forms a short-lived seed bank
