Dear Christine,

Thanks for reporting this population of parrot feather. I will forward this report to the 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. Parrot feather is not uncommon different areas of the coast, 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.

Thanks again,

Location

This aquatic species was found in Beaver Creek, a tributary of the Tillamook river. Species can be identifed from the road and can be seen as far as the eye can see up river (about 500 feet). More surveys are needed upstream along Beaver Creek and downstream and in the Tillamook River to see if parrot feather is present.
