Beech Scale Disease Shows Up In NE Ohio

CLEVELAND - "A disease that has killed beech trees in the eastern United States since the 1930s was found at an arboretum in northeast Ohio, state foresters said. The bark disease was discovered in December at Holden Arboretum in Kirtland, about 20 miles northeast of Cleveland.

"There is the potential it could have a major impact on Ohio's forests," said Jennifer Koch, a research biologist with the U.S. Forest Service's Northeastern Research Station in Delaware.

EDIT

Ohio has an estimated 90 billion beech trees, which make up about 10 percent of the state's forests.


Foresters discovered scale insects on a few beech trees at the Kirtland arboretum 1985, but it wasn't until December that a fungus indicating the bark disease began to appear. Having both the scale insect, which gives trees a whitewashed appearance, and the fungus can kill a tree in three to five years, Koch said."
