The Asian longhorned beetle, native to China, is a serious threat to hardwood trees in the U.S. So far, populations of the beetle have been confined to Chicago and New York. Foresters are concerned that more non-native species will be introduced through expanded global trade. Photo courtesy of USDA-APHIS.
Forests in the Midwest may be under siege from exotic species more often in the future… partly because of international trade. The Great Lakes Radio Consortium’s Rebecca Williams explains:

The Asian longhorned beetle is native to China.
The beetle caught a ride to the U.S. in the wooden packing material of
imported goods. So far, the beetle has been found in New York and
Once a tree is infested with beetles, the best way to stop the beetles from spreading is to destroy the tree.
A National Academy of Sciences study predicts that threats to native species will increase as trade opens up between the U.S. and China. The authors say that China may become a new “donor region” for species that could become invasive.
Entomologist Deborah McCullough is an author of the study.
“You can kind of visualize this whole complex of insects and weeds and plant pathogens in Asia that haven’t had a pathway, they haven’t had a route to be brought to the country yet… and we really don’t know what all could end up coming in.”
Dr. McCullough says because China’s range of climates and plant life are similar to that of the U.S., many species that make it over here have a chance to become established.

Earlier this month, the Department of Energy announced that
spent nuclear fuel from American research reactors will be melted down
and stored, rather than reprocessed and reused. The announcement comes
at the same time that Canadian researchers are planning to recycle
waste into reactor fuel. Great Lakes Radio Consortium commentator
Suzanne Elston says that this is one time when recycling shouldn’t be an
The International Joint Commission is looking into the issue of
diversion of Great Lakes water. They’ve been given six months to
recommend an interim policy. Over the last two weeks, they’ve been
conducting a series of public forums on the issue. I-J-C Chairman Tom
Baldini has a few thoughts:
Another skirmish is erupting in the ongoing battle between Ontario and
Minnesota over sport fishing. Ontario recently banned the importation
of leeches without a permit. The reason – the Province says it doesn’t
want to risk exotic species piggy-backing on the popular bait. But as
the Great Lakes Radio Consortium’s Stephanie Hemphill reports, experts
on controlling exotic species say the reasoning is faulty:
