Phytophthora ramorum


Dead oak trees are becoming increasingly common in Marin County, due to the "oomycete plant pathogen Phytophthora ramorum" that leads to the phenomenon known as "sudden oak death."

All along Sir Francis Drake Boulevard in West Marin you can see these trees scattered throughout the forest. I saw this particular oak tree in the Devil’s Gulch campground area opposite the horse pens, with a California Buckeye in the background. Strange that it’s so picturesque.
