Family: Pinaceae

High Risk Traits:

• Naturalized in Great Britain
  
• Potentially allelopathic
  
• Possibly increased fire risks
  
• Tolerates many soil conditions (and potentially able to exploit many different habitat types)
  
• Forms dense thickets
  
• Hybridizes with other Abies species
  
• Self-compatible
  
• Wind-dispersed seeds

Low Risk Traits:

• Despite ability to spread, no negative impacts have been documented
  
• Browsed by animals (which could limit its ability to spread)
  
• Non-toxic and non-allergenic
  
• Shade-intolerant
  
• Long time to reproductive maturity (25+ years)
  
• Does not spread vegetatively
  
• Used for Christmas trees
  
• Large, wind-dispersed seeds unlikely to be inadvertently dispersed
