Family: Myrtaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in tropical climates
  
• Naturalized on Oahu, Hawaiian Islands
  
• Other Syzygium and Eugenia species are invasive
  
• Shade-tolerant
  
• Reproduces by seeds
  
• Seeds dispersed by birds, other frugivorous animals, possibly by water and intentionally by people
  
• Gaps in biological and ecological information reduce accuracy of risk prediction

Low Risk Traits:

• No reports of negative impacts in native or introduced range
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Not reported to spread vegetatively
  
• Seeds recalcitrant, lose viability rapidly and will not form a persistent seed bank
