Family: Myrtaceae

High Risk Traits:

• Naturalized in New Zealand, and possibly elsewhere (but not in the Hawaiian Islands to date)
  
• 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
