Fighting Beech Bark Disease

Forestry experts throughout the Midwest have been experimenting with new ways to fight beech bark disease. The disease has already killed millions of beech trees in Pennsylvania, Ohio, Ontario and Michigan. The Great Lakes Radio Consortium’s Matt Shafer Powell has more:

Beech bark disease is actually a deadly tag-team combination of an insect that invades a tree and a fungus that finishes it off. Michigan State University entomologist Deb McCullough is one of several scientists trying to stop the spread of the disease in Michigan…


“What we’re going to see in the forest is gonna be something like Dutch Elm disease, the biggest, oldest beech trees are most vulnerable to this insect and to the disease, and as beech bark disease moves through the state, those are the ones that are going to die out first.”


McCullough says researchers have had some limited success with injecting pesticides into infected trees. And scrubbing the trees with soapy water seems to work too. But she says such methods simply aren’t practical when you’re dealing with the millions of beech trees that inhabit the region’s forests. For the Great Lakes Radio Consortium, I’m Matt Shafer Powell.

A disease that’s destroying trees is spreading through parts of the Great Lakes Region. The Great Lakes Radio Consortium’s Lester Graham reports.


Beech bark disease has been damaging beech trees in eastern Canada and New England for a century. The disease has been creeping westward across the upper sections of U.S. since then. Last year Beech bark disease was discovered in the upper peninsula of Michigan. The disease is caused by two pests. First an insect called the wooly beech scale attacks the tree and open wounds. Then a fungus enters the bark, killing the trees. Often the beech trees are knocked over by high winds because of the damage done to them. Not all beech trees succumb to the disease. Scientists are now studying trees that appear resistant to beech bark disease, and they’re also looking for natural predators of the scale insect or the fungus that damages beeches. In the meantime, forest officials are cutting down beeches damaged by the disease. Before the trees fall down on someone unexpectedly.
