Family: Myrtaceae

High Risk Traits:

• Broad climate suitability (temperate to subtropical)
  
• Naturalized in Hawaii and beyond native range
  
• Acts as an agricultural, environmental, and congeneric weed
  
• Forms dense thickets that suppress other plants
  
• Tolerates a wide range of infertile soils
  
• Produces viable seed & hybridizes naturally
  
• Self-compatible, no specialist pollinators needed
  
• Propagules dispersed intentionally (horticulture), unintentionally, and by wind
  
• Prolific seed production
  
• Benefits from fire (post-fire seed release)

Low Risk Traits:

• Unpalatable to grazing animals but not toxic
  
• No evidence of toxicity to humans or animals
  
• No vegetative fragmentation
  
• No persistent soil seed bank (seed bank short-lived)
  
• Does not resprout after decapitation (cutting effective)
