Family: Poaceae

High Risk Traits:

• Broad climate suitability and elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Grows in tropical climates
  
• Var. pumilus naturalized on Midway, Oahu, Hawaii and species on Kauai (Hawaiian Islands); also reported in Central Europe, South Africa, and Japan
  
• An aggressive, weedy self-seeder of disturbed habitats with potentially negative environmental impacts
  
• Other Andropogon species are invasive weeds
  
• Tolerates many soil types (if damp)
  
• Reproduces by seeds
  
• Hybridizes with other Andropogon species
  
• Self-fertile
  
• Seeds dispersed by wind, water, as a potential contaminant, and intentionally cultivated
  
• Herbicides not very effective
  
• Tolerates cutting, mowing and grazing

Low Risk Traits:

• Unarmed (no spines, thorns, or burrs)
  
• Provides forage for grazing animals
