Family: Arecaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in tropical climates
  
• Other Arenga species may be invasive
  
• Fruit may be toxic if consumed by humans
  
• Seeds presumably dispersed by birds and intentionally by people
  
• May spread by suckering
  
• Limited ecological information makes accurate risk prediction difficult

Low Risk Traits:

• No reports of invasiveness or naturalization, but no evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental
