Look for new invaders every time you are outdoors. Scan the area and pay special attention to: 

• Pathways: Roads, trails, edges
• Habitats: Aquatic plants in water bodies, understory plants on forest floor, etc.
• Distribution: Plants that seem out of place
• When you find something:
  • Double check the ID (consult a guidebook or contact an expert at Benton SWCD or OSU Extension Master Gardeners). 
  • Record the location on a map. 
  • Record the size of the infestation (# of plants, area covered). 
  • Take a digital photo of the plant. 
  • Follow the link below to report with as much info as you have.
