Researchers might have a partial solution to the problem
of beech bark disease. The disease has killed millions of beeches
in the Northeast and is advancing on the woodlands of the Midwest.
The Great Lakes Radio Consortium’s Tracy Samilton has this report:


Beech bark disease happens when an insect infests beech trees. Then the
trees are killed or crippled by an opportunistic fungus. Where the
disease has struck, researchers found one to five percent of the trees had
natural resistance to the insect.


Jennifer Cook is a USDA Forest Service researcher.Her experiments found that seeds from two resistant parent trees produced progeny that are also resistant. That could set the stage
for reforestation and even pro-active plantings.


“People can plant them before the disease gets there and
therefore lessen the impact on their forest lands.”


Cook says if you’ve got a big beautiful beech tree you want to save, you
can scrub the tree’s bark with insecticidal soap once a year. Of course
it would be impossible to scrub every beech tree in the forests.
