Family: Marattiaceae

High Risk Traits:

• Grows in regions with tropical climates
  
• Shade-tolerant
  
• Reproduces by spores and vegetatively by rhizome division
  
• Spores presumably dispersed by wind, and water
  
• Presumably produces prolific numbers of spores
  
• Gaps in ecological information reduces accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization, and in decline within native range, but limited evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns or burrs)
  
• Palatable to pigs, goats and other browsing/grazing animals (contributing to decline within native range)
  
• Non-toxic
  
• Ornamental
  
• Propagation from spores reported to be difficult
