Family: Caryophyllaceae

High Risk Traits:

• Elevation range exceeds 3000+ m, demonstrating environmental versatility
  
• Naturalized and able to grow in tropical climates
  
• Widely naturalized, including all main Hawaiian Islands
  
• A weed of lawns, roadsides, pastures, open woodlands and wastelands
  
• Other Cerastium species have become weeds

Low Risk Traits:

• Despite widespread naturalization and reports of weediness, impacts are generally unspecified or not considered to be significant in natural communities
  
• Unarmed (no spines, thorns or burrs)
  
• Palatable to browsing and grazing animals
  
• Non-toxic
  
• Effectively controlled by herbicides
