Family: Araucariaceae

High Risk Traits:

• Naturalized in the United Kingdom
  
• Rigid spines on the trunk and leaf tips
  
• Tolerates moderate to heavy shade
  
• Tolerates many soil conditions (and potentially able to exploit many different habitat types)
  
• Occurs in pure stands in native range
  
• Can produce sucker sprouts in natural stands (spread vegetatively)
  
• Able to coppice and tolerate fires

Low Risk Traits:

• Despite ability to naturalize, no negative impacts have been specified
  
• Palatable to grazing animals (may limit spread in introduced range, but threatens tree in native range)
  
• Non-toxic
  
• Self-incompatible (dioecious)
  
• Long time to reproductive maturity (20+ years)
  
• Landscaping and ornamental value
  
• Timber tree
  
• Large, edible seeds, unlikely to be inadvertently dispersed
  
• Seeds recalcitrant, and unlikely to persist in the soil
