Family: Fabaceae

High Risk Traits:

• Broad climate tolerance (wide rainfall, altitude, and habitat range)
  
• Repeated introductions outside native range
  
• Naturalized in Hawaii, Puerto Rico, and Virgin Islands
  
• Nitrogen-fixing, can alter soil and habitats
  
• Seeds toxic to cattle
  
• Produces viable, long-lived, hard-coated seeds
  
• Can be bird-dispersed
  
• Seeds survive gut passage and germinate in dung
  
• Tolerates heavy pruning and transplanting

• Pods palatable to livestock
  
• Edible pulp for humans (not toxic)
  
• Intolerant of shade
  
• Does not form dense thickets
  
• No vegetative reproduction
  
• Seeds not dispersed unintentionally, by wind, or by water
