A state has abandoned its efforts to stop the spread of a tree-killing beetle
because of the cost. The Great Lakes Radio Consortium’s Jeff Bossert
reports:


The emerald ash borer has been spreading in the upper Midwest…
killing millions of ash trees along the way. Since it was first discovered
in northern Indiana two years ago… more than 100-thousand ash trees
have died in that state.


The infestations are hard to find… and state officials say cutting down
trees hasn’t been enough to stop the beetle. Now, the state’s Department
of Natural Resources has decided to stop cutting down trees, and instead,
just monitor the infestation.


State entomologist Bob Walz says he hopes technology will one day
reverse things.


“It’s our hope in the next several years that we’ll have a better tool to
conduct surveys and be able to better limit where emerald ash borer is
found, but at the present time we just don’t have a good tool and
therefore, we’re always playing catch up.”


State officials say some of the blame can be placed on those who ignore
warnings… and take firewood from infected areas.

More Trees Lost to Emerald Ash Borer

A tree-killing beetle continues to spread through the region. The beetle has left millions of ash trees in its wake. Now it’s spread into northeast Indiana and will cost one city there much of its natural beauty. The Great Lakes Radio Consortium’s Jeff Bossert reports:

A tree-killing beetle continues to spread through the region. The beetle has left millions of ash trees in its wake. Now
it’s spread into northeast Indiana and will cost one city there much of its
natural beauty. The Great Lakes Radio Consortium’s Jeff Bossert
reports:


A survey of ash trees in Decatur by the state’s Department of Natural
Resources shows the emerald ash borer has been wreaking havoc there
for some time on some trees, as long as 4 or 5 years. So, the city recently
announced it would spend 1-million dollars to cut down about 15-
thousand of them.


The ash borer slowly kills trees by making tunnels under the bark and
cutting off the food supply.


City Forester Dwight Pierce says the trees are almost entirely
infested. He hopes this move will end any concerns of the ash borer
showing up elsewhere in the state.


“We don’t want to let it spread out of our city and get into adjoining
cities, and spread farther south in the state. We’re still hoping we can
control it here before it gets down to south of Indianapolis and it turns
into a whole forest again. We obviously don’t want to let it get into
that.”


Pierce says the beetle likely came from firewood brought in from
infected areas in Michigan or Ohio… and he hopes residents of Decatur
heed warnings about moving firewood across state lines.

Defending Against Ash Borer

The Emerald Ash Borer is being found in new places. The Great Lakes Radio Consortium’s Jeff Bossert reports officials are emphasizing a different way to stop the small metallic-green bug:


The emerald ash borer is killing ash trees throughout much of Michigan, and it’s spreading. It’s been discovered in parts of Ohio, Indiana, and Ontario.


Michigan State University entomologist David Smitley suggests homeowners work to stop the spread of the insect by treating the ash tree while they’re still healthy.


“That’s really critical. You need to start with a healthy tree, and that’s why we’re trying to get the word out.”


Smitley says homeowners in Michigan should consider applying insecticides
this fall and every subsequent spring, but University of Illinois
entomologist James Appleby says that’s not enough. That’s because too many don’t know about the emerald ash borer, and will fall back on spraying when it’s too late.


“I hate to get that kind of publicity out. I think the main thing
here is that we just be aware that we not bring any firewood from Michigan
into Illinois or Indiana or any other state.”


Appleby says a recent survey in Michigan revealed fifty percent of those
questioned had never heard of the emerald ash borer.

Solution for Arsenic in Drinking Water?

Researchers believe they have found a way to reduce arsenic levels in drinking water. They say, for people to drink water from wells or aquifers, the solution starts at the source. The Great Lakes Radio Consortium’s Jeff Bossert explains:


Chronic exposure to arsenic in drinking water has been linked to a variety of health concerns, including hypertension, cardiovascular disease, and cancer.


Researchers from the University of Illinois collected groundwater samples from 21 wells. They found that the wells with almost no arsenic in the water also contained high levels of sulphate-reducing bacteria, which convert the arsenic into a solid, where it drops out of the water. Dr. Craig Bethke led the study.


“What we’re saying is that if there’s sulfate in the water, then there’s probably sulfate-reducing bacteria active in the subsurface, and that means that a simple field test, which is very inexpensive and very rapid to protect sulfate, could identify safe water sources.”


Bethke says places where aresenic levels are high, sulphate salts, such as gypsum and calcium sulphate, can be injected underground to reduce arsenic levels.


Researchers say this information could prove to be invaluable in places where aresenic contamination is a major problem, including parts of the U.S., Australia, and Mongolia. The researchers’ findings were published in the journal Geology.
