Family: Fabaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Able to grow in temperate and tropical climates
  
• Naturalized in the Hawaiian Islands (Kauai, Maui, Hawaii) and elsewhere
  
• A weedy plant and potential agricultural and environmental weed
  
• Other Vicia species are invasive
  
• Seeds may be toxic
  
• Tolerates many soil types
  
• Climbing plant (can possibly smother or suppress other vegetation)
  
• Reproduces by seeds
  
• Hybridizes with other Vicia species
  
• Self-compatible
  
• Reaches maturity in <1 year (annual)
  
• Seeds dispersed by birds and other animals (internally), by adhering to boots in mud, by water, and intentionally by people
  
• Prolific seed production with some subspecies

Low Risk Traits:

• Although weedy, regarded as a desirable plant for weed suppression or soil fertility in certain situations
  
• Unarmed (no spines, thorns, or burrs)
  
• Provides fodder for livestock
  
• Not reported to spread vegetatively
  
• Herbicides provide effective control
