Knotweed (unknown species) (Fallopia sp.) on Nov 6, 2008

Originally reported as Japanese Knotweed (Fallopia japonica)

Submitter does not have a specimen

Description of specimen

Large patch of tall plants, well established in a seasonal drainage. Accessible just off of and above and below the trail. Difficult terrain. I reported this infestation to City of Portland Parks Bureau several months ago. I received no response... I'm so pleased I found your site via OPB web site. I have not tracked how far uphill and downhill this infestation goes but due to the slope of the terrain and the fact that it is a natural drainage one might suspect it covers a fairly large area. This is much larger area than the two other patches I just reported on SW Humphrey Blvd.
