DPG pointing out discolored inner bark caused by Port Orford cedar root disease. Near Bandon, Oregon. Port-Orford-cedar root disease is best identified by the cinnamon-colored inner bark and cambium that abruptly joins creamy white, healthy inner bark in roots and lower boles. Just prior to tree death, the discolored zone may extend 2 to 5 feet aboveground. This symptom is most readily seen on trees that are wilted or yellow. In trees that have been dead for several months, all the inner bark...
