Report a Weed

Oregon Invasive Hotline website

Help stop the spread of invasive weeds by reporting them! If you think you have spotted a plant from the EDRR list, here’s what you do:

Step 1: Recording Information About an EDRR Sighting

If you suspect you have found any of the EDRR weeds, record as much information about the plant and the site as possible. The most important things to collect at a suspected sighting are listed below. If you can’t collect all of the following information, please record as much as possible. The more information you record, the more likely it is that we will be able to find the reported site again.

  • Take a picture of the plant: Include something to show scale (a ruler or a common object like a quarter) and close-ups of distinctive features of the plant.
  • A written description of the plant: Flower color, shape and size, leaf shape size, does the plant have fibers, etc.
  • Location information: GPS coordinates are the best but detailed written directions to the site work if you don’t have a GPS. Information such as the closest intersection or mile marker, or how far past a trail or bridge crossing as well as nearby landmarks is most helpful.
  • Size of infestation: How many feet wide and how many feet long is the weed patch?
