Family: Salicaceae

High Risk Traits:

• Mostly temperate but can grow in tropical climates
  
• Broad climate suitability
  
• Reported to be invading Houston’s bayous and creeks
  
• Branches spiny when young
  
• Shade-tolerant
  
• Tolerates many soil types
  
• Fleshy-fruited berries presumably adapted for dispersal by birds and other frugivorous animals
  
• Tolerates severe pruning

Low Risk Traits:

• Popular ornamental plant in mainland US with limited reports of escape or invasiveness
  
• Palatable to browsing animals
  
• Non-toxic
  
• Promoted for use in fire resistant landscapes
  
• Missing information on biology and ecology makes accurate risk prediction difficult
