SOD: still spreading in the bay area
/
A nice article in SF Chron on Matteo's citizen science approach to mapping new SOD spread.
The article states: The deadly pathogen known as sudden oak death is spreading throughout the Bay Area, infecting more trees in more places than have ever been seen before, according to scientists tracking the disease. The Forest Pathology and Mycology Laboratory at UC Berkeley used 10,000 tree and plant samples collected by 500 citizens between April and June this year to document a dramatic increase in the infection rate from Napa to the Carmel Valley and virtually everywhere in between.
