Commentary

Dear David,

Thanks for reporting yellow flag iris! You are the first person from our weed watchers training to report one of our watch species through the hotline! Congratulations!

I will forward this report to Rob Emanuel, OSU Extension agent in Tillamook who is the lead for receiving and processing these reports. He will evaluate the location and determine who is responsible for controlling that particular infestation. Yellow flag is fairly abundant in the Tillamook area, so it is possible that patch will not be prioritized for control. However, please don’t be discouraged. Your efforts are extremely valuable as more information about its distribution will improve our database and planning efforts. I hope you keep on reporting!

Thanks again,
