Family: Fabaceae

High Risk Traits:

• Broad climate tolerance (elevation 150–1400 m, various rainfall regimes)
  
• Native to tropical/subtropical regions
  
• Widely introduced as an ornamental/sacred tree
  
• Shade-tolerant
  
• Forms dense thickets
  
• Produces viable seed
  
• Intentionally dispersed by people
  
• Water-dispersed (riparian habitat)
  
• Coppices well (regenerates after cutting)

Low Risk Traits:

• No known naturalization outside native range
  
• Not recorded as a weed anywhere
  
• No weedy congeners
  
• Lacks spines, thorns, or burrs
  
• Non-toxic to animals or humans
  
• No fire hazard
  
• Narrow soil tolerance (prefers specific, well-drained soils)
  
• Takes 4–6 years to reach maturity
  
• No unintentional dispersal (large seeds/pods)
  
• Not wind- or bird-dispersed
  
• Recalcitrant seeds (no persistent seed bank)
