P. ramorum in Washington waterways

Washington had two repeat P. ramorum-positive waterway detections in May. One of the sites has been positive since 2009 and the other since 2010. Each positive stream feeds into the Sammamish River. Both sites have had positive samples recovered upstream from the confluence of the water course and the Sammamish (baiting by WSDA and WA DNR); the inoculum source for each is unknown.
