Family: Poaceae

High Risk Traits:

• Broad climate suitability (primarily temperate)
  
• Reported to be naturalized in Brazil
  
• Deer and rabbit resistant, indicating unpalatability
  
• Shade-tolerant (could potentially spread into intact forest)
  
• Reproduces by seeds and vegetatively by rhizomes
  
• Intentionally spread by people and likely by water
  
• Gaps in biological and ecological information may reduce accuracy or risk prediction

Low Risk Traits:

• Widely cultivated ornamental, with no reports of negative impacts.
  
• Recommended as a non-invasive alternative to other weedy grasses
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Herbicides would likely provide effective control if necessary
