Have you got an oak in your backyard? Then you may want to know how much longer it's likely to escape the scourge that is steadily wiping out California's signature trees.
The University of California, Berkeley's Forest Pathology and Micology Lab can help. The lab just posted a map that shows the progress of sudden oak death. By downloading the map you can find out the location of the nearest blighted trees, and consider measures to protect your oak, reports the San Francisco Chronicle.
