High Risk Traits:

• Large surface roots crack sidewalks and foundations.
  
• Limbs break easily in wind, posing a hazard to people and property.
  
• Sawdust inhalation causes respiratory allergies.
  
• Seeds contain saponins; toxic to mammals if prepared improperly.
  
• Resprouts vigorously after cutting; difficult to kill.
  
• Forms a persistent seed bank in the soil.

Low Risk Traits:

• Not documented as an agricultural or environmental weed.
  
• Does not form dense thickets or displace native vegetation.
  
• Shade-intolerant; cannot invade established forests.
  
• Natural regeneration is rare due to high seedling mortality.
  
• Seeds require large animals for dispersal; not spread by wind or birds.
