Family: Blechnaceae

High Risk Traits:

• Thrives in tropical climates
  
• Possible broad elevation rante
  
• Possibly naturalized in Africa
  
• Other Blechnum species have become invasive
  
• Possibly Shade-tolerant
  
• The dominance of B. brasiliense in some Brazilian forests suggests this species hampers the development of shorter-statured plants by its shading effect
  
• Reproduces by wind- and possibly water-dispersed spores
  
• Can reproduce vegetatively by offshoots from trunk
  
• Possibly forms a persistent spore bank

Low Risk Traits:

• No reports of invasiveness or detrimental impacts
  
• Unarmed (no spines, thorns or burrs)
  
• Non-toxic
  
• Ornamental value
  
• Gametophytes may be self-incompatible
