Sudden Oak Death
Sudden Oak Death disease has devastated oak forests along the California and Oregon coastal communities. The disease has expanded to affect other native tree and shrub species. The good news it does not enter the vascular system of many of the other plants that get the disease. Leaf petioles and leaf necrosis are often the only visible signs of the disease. The most susceptible trees are the coast live oak (Quercus agrifolia) Black oak (Quercus kellogii) and the tan oak (Lithocarpus densiflorus)
