Family: Poaceae

High Risk Traits:

• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in tropical climates
  
• Widely naturalizing, including the Hawaiian Islands of Kauai, Oahu, Kahoolawe, Maui, and Hawaii
  
• Considered an environmental weed in Queensland, Australia,
  
• Other Digitaria species have become invasive
  
• High flammability (may increase fire risk in arid, fire prone habitats)
  
• Forms dense stands in Australia, excluding other vegetation
  
• Tolerates many soil types
  
• Spreads vegetatively
  
• Tolerates grazing and fire

Low Risk Traits:

• Not reported to be a seriously invasive or habitat-modifying weed in the Hawaiian Islands
  
• Unarmed (no spines, thorns or burrs)
  
• Non-toxic
  
• Palatable, and provides valuable forage for livestock
  
• Shade-intolerant
  
• Does not produce seeds
  
• Lack of seed production could limit potential to disperse accidentally
  
• Impacts of Two-lined Spittlebug (TLSB) in Hawaii will likely reduce pangola grass cover and minimize risk of invasiveness where TLSB is present
