Sudden oak death discovered in new areas of Mattole Featured

Written by 

According to KMUD News Coordinator, Cyntia Elkins:       
"Sudden oak death was discovered for the first time in the Mattole River last year, and it has now been detected in an additional tributary of the watershed.  Scientists conducted water samples in the watershed earlier this year.  It was found in the mainstem at Whitethorn and Mattole Canyon Creek last year.  Results this year show it is also present in Grindstone Creek, and is affecting both the east and west forks of Mattole Canyon Creek.  Stream sampling uses leaves in the water that will become infected if the pathogen is present.  It’s a way to detect sudden oak death before it can be visibly seen affecting trees.  Dr. Dave Rizzo is a professor of plant pathology at U.C. Davis.  He was on the team of people that collected the first isolates that pinned sudden oak death on phytophtora ramorum.  That was back in 2000."
