Thanks for reporting yellow flag iris at Delta Pond. Yellow flag has the capacity to completely dominate the shoreline and should be controlled while populations are patchy and still low. I believe the City of Eugene is aware of the yellow flag at delta ponds, but I forward this report along just in case. It is a useful reminder. Thanks again!
