Commentary

Emily,

Thank you for reporting this infestation of Shining Geranium to the Invasive Species Hotline. I appreciate you taking the time to pass this information along. As you know Shining geranium is fairly widespread throughout our area, but if the patch is isolated it may make sense to control this population. As I mentioned I will share this with other land managers working in that area. Thanks and all the best,

Remedy

How to control shiny geranium, from WA noxious weed control board: Individual plants and small infestations can easily be controlled by carefully hand-pulling, bagging, and putting in the trash. Make sure to remove its fibrous roots to prevent resprouting. Larger populations can be covered with sheet mulch - ideally overlapping pieces of cardboard covered with a thick layer of woodchips. Make sure to repeatedly monitor and control seedlings before they set seed.

Location

In June, I observed the species growing on the bank of a ditch along the road. The location on the map is approximate. I believe it was prior to the road turning into a dirt road. If you follow the dirt road, it appears that you are walking on someone's driveway. Toward the house their is a trail that leads down to the river. I did not see the species along the trail.
