Family: Myrtaceae

High Risk Traits:

• Congeneric weeds present (other Eucalyptus species are listed as weeds)
  
• Broad climate tolerance (heat, frost, alkaline soil, salinity)
  
• History of repeated introductions outside native range
  
• Unpalatable to grazing animals (chemical deterrence)
  
• Wide soil tolerance (sandy to clay)
  
• Produces viable seed
  
• Intentionally dispersed by people (popular street tree)
  
• Wind‑dispersed minute seeds
  
• Prolific seed production
  
• Tolerates mutilation, fire, and cultivation (epicormic buds)

Low Risk Traits:

• No evidence of naturalization outside native range
  
• No documented weediness (garden, agricultural, or environmental)
  
• Probably self‑sterile (requires cross‑pollination)
  
• No vegetative reproduction
  
• No persistent seed bank (seeds viable <1 year)
  
• No spines, thorns, or burrs
  
• No evidence of allelopathy, toxicity, or allergenicity
  
• Not shade tolerant (requires full sun)
