Fungal Disease Is Killing Oak Trees in Parts of U.S.

Publication: National Geographic News   Date: December 6, 2001   View Article

Scientists are in a race against time to stifle the spread of a fungal disease that has killed tens of thousands of stately oak trees in California and southwestern Oregon. Many people fear it may spread and similarly wipe out large swaths of forest in the eastern United States and Canada.

The disease, called sudden oak death, was first detected in 1955 in California tan oaks. Since then, it has killed more than 100,000 tan oaks, coast live oaks, black oaks, and Shreve’s oaks in coastal regions of northern California, and more recently in southwestern Oregon.
