Family: Poaceae

High Risk Traits:

• Broad climate suitability and elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Widely naturalized (but no evidence in Hawaiian Islands)
  
• Regarded as a weed or weedy
  
• Other Festuca species have become invasive
  
• Listed as a severe allergen to susceptible individuals
  
• Moderate shade tolerance
  
• Tolerates many soil types
  
• Reproduces by seeds
