Family: Arecaceae

High Risk Traits:

• Grown throughout the tropics; history of repeated introductions
  
• Tolerates part shade
  
• Tolerates a wide range of soil types (sandy, loamy, clay, acidic, neutral, alkaline)
  
• Produces viable seed
  
• Self-compatible (single plants produce fertile seed)
  
• Intentionally dispersed by people
  
• Propagules likely bird-dispersed
  
• Propagules survive passage through gut (pig food)

Low Risk Traits:

• No evidence of naturalization or weediness
  
• No spines, thorns, or burrs
  
• No evidence of allelopathy or parasitism
  
• Not toxic to animals or humans
  
• Does not form dense thickets
  
• No vegetative fragmentation
  
• Requires insects for pollination (not self-pollinating within same inflorescence)
  
• Long time to first flowering (8–10 years)
  
• No seed attachment for external dispersal
  
• Seeds relatively large, not likely as produce contaminant
  
• No persistent seed bank (seeds must be fresh; germinate in weeks to months)
  
• Single trunk with single meristem (not tolerant of mutilation/fire)
