What Is the Threat?

Oak wilt is an invasive disease caused by Ceratocystis fagacearum, which is a fungal pathogen. It was first discovered in New York, our nearby neighbor, in 2008.

That fungus causes a vascular infection in the tree, preventing it from getting the necessary nutrients and water needed to grow and thrive. The entire circulatory system of the tree is affected, killing it quickly. 

Oak wilt can spread in two ways.

In dense areas of forest, oak wilt can spread from diseased trees to healthy trees through their root systems. This manner of spreading takes longer but is still effective. A faster, broader way of spreading is through Nitidulid beetles that feed on a diseased tree and then spread the disease through a fresh wound in a healthy tree.

Oak wilt has been found in sixteen different native oak species.

Where Is the Threat?

Oak wilt is most prevalent in the eastern part of the USA.

In fact, it’s one of the most serious diseases facing oak trees, killing hundreds of thousands every year in the upper Midwest alone.

Although oak wilt disease has only been found in western Maryland in small numbers, it’s still labeled as a species of concern. Not only does Maryland rely heavily on its oak tree population for filtering water, cleaning the air, and providing a home for wildlife, but it spreads rapidly. 

What Are the Symptoms of Oak Wilt?

During the spring and early summer months, keep an eye on the tops of oak trees, where oak wilt disease first shows itself.

Leaves begin turning from green to brown, forming an obvious juxtaposition of color. By mid-summer, an extensive number of leaves will fall because of this. 

You may also notice dark vascular streaking inside the oak or splitting bark on the outside.
