Family: Fabaceae

High Risk Traits:

• Naturalized in Norfolk Island and Hawaii (Oahu)
  
• Thrives in tropical climates
  
• Armed with spines
  
• Tolerates many soil conditions (and potentially able to exploit many different habitat types)
  
• N-fixing (may alter soil chemistry)
  
• Branch fragments can root; spreads vegetatively
  
• Possibly water-dispersed
  
• Hard seeds likely persist in seed bank

Low Risk Traits:

• Landscaping and ornamental value
  
• Large pods and seeds unlikely to be inadvertently dispersed
