Hi Friends of Sausal Creek,

As the FOSC November newsletter will be out late, I wanted to highlight 
the Sudden Oak Death (SOD) Blitz 2016 meeting this week:

*When:  Wednesday, 11/9/**2016, **7:30 – 9:00 p.m.*

*Where:  UC Berkeley, **132 Mulford Hall, Berkeley, CA*

Come hear the results from the survey last April.  Thank you to all who 
helped with the survey.

Following is an article from the November newsletter of our sister 
organization Friends of Five Creeks.

Enjoy your weekend!

*/Sudden Oak Death on the march -- including in El Cerrito /*

Last winter's drought-breaking rains were welcome -- but they also 
renewed the advance of Sudden Oak Death, the water-loving, fungus-like 
mold that is decimating our beautiful Coast Live Oaks (/Quercus 
agrifolia/).

This spring 2016 citizen-science survey found infection for the first 
time on Mt. Diablo and in San Luis Obispo, extending the range. 
Infection increased again in areas where it had subsided during the 
drought, including parts of Napa and Sonoma Counties. Closer to home, 
a new outbreak was found in Piedmont, and there was significant spread 
for the first time in San Francisco's Golden Gate Park, including the 
first findings in Strybing Arboretum.

Live oaks are killed by the pathogen, but they do not spread it. The 
main carriers are our familiar California Bay trees (/Umbellularia 
californica/), which are not harmed. Thus, the annual volunteer survey 
looks for bay leaves that appear infected (right). This year's 
volunteers found infection in additional areas in the hills above the UC 
Berkeley campus. In Oakland's Sausal Creek drainage, the pathogen was 
found downstream as far as the Leimert Bridge. To the north, additional 
infected samples were found in the upper Pinole Creek watershed and in 
the Alvarado Park area.

*In Friends of Five Creeks' area, infected bay trees were found for the 
first time in Hillside Natural Area's northern portion, north of 
Potrero, and from the crest of the hills down to Arlington. *None has 
yet been found in the main Hillside Natural Area.

Infected bays also were found for the first time on the Blackberry Creek 
drainage in and above John Hinkel Park. Past years' surveys found that 
the pathogen in the Cerrito Creek Canyon down to Visalia, and the 
Codornices Creek watershed above Euclid.

UC Berkeley's Dr. Matteo Garbelloto coordinates the spring surveys, in 
which hundreds of citizen scientists join the hunt. Friends of Five 
Creeks has recruited East Bay volunteers for years.

Dr. Garbelloto announces results in fall. *East Bay results and new 
recommendations* *for protecting specific trees and slowing the spread 
of SOD **will be covered **7:30 - 9 PM Wed., Nov. 9, in Room 132 Mulford 
Hall on the UC Berkeley campus. *

SOD, a free mobile app, and a Google Earth map of findings year by year
