Family: Arecaceae

High Risk Traits:

• Suited to both tropical and subtropical climates; tolerates light frost
  
• Repeatedly introduced outside native range (e.g., California, Hawaii, Australia, Texas)
  
• Seeds dispersed by birds
  
• Seeds survive passage through bird guts

Low Risk Traits:

• No reported naturalization outside native range
  
• Not a weed (garden, agricultural, or environmental)
  
• No known weedy congeners
  
• Lacks spines, thorns, or burrs
  
• Not allelopathic, parasitic, or toxic
  
• Not shade-tolerant (requires high light)
  
• Narrow soil tolerance (well-drained, rocky/sandy/limestone only)
  
• No vegetative reproduction
  
• Slow-growing; late reproductive maturity (~4 m height)
  
• Large seeds limit unintentional dispersal or contamination
  
• No persistent seed bank (short-lived seeds)
