With above normal rain in much of the country this spring mosquitoes have been heavier in many
areas. The quick warm up after a cool spring has also helped hatch out a lot of the pests. The
GLRC’s Lester Graham reports you only have to step out your door to see the result:


It’s not so much hot days, but the fact that the nights are warmer that’s helping the skeeter broods
hatch out in hordes. I’ve been painfully aware of the mosquitoes this year because I live right next
to a river in a year where there’s been plenty of rain to make little pools of stagnant water
everywhere. It’s a real nuisance.


(sound of mosquitoes)


“I’m in a very hot car and a lot of mosquitoes are trapped in here with me.
(pause) All these mosquitoes got here, just because I opened my hatchback and took
some groceries out, and they just swarmed in.”


(sound continues… smack!)


I don’t like ‘em much. Most people don’t have a very high tolerance for mosquitoes. They’ve
actually studied that. John Witter is a biologist with the University of Michigan who spends a lot of
time in the woods, studying bugs. He says there was a Michigan State University study that tracked
interaction of people and mosquitoes while camping.


“If you have more than about four mosquitoes landing on your body per minute, the people leave
the hiking trail. They go back to their campers because they just cannot handle that annoyance.
So, higher population numbers of mosquitoes, more bites, more annoyance.”


But not everyone, or everything, can get away from the pests. Jenny Barnett works at the Binder
Park Zoo in Battle Creek, Michigan. The zoo is in the middle of a forest. The mosquitoes love it
there.


(sound of birds)


The zoo’s tried to use different kinds of fumigation in past years, but with sensitive animals and birds
like the ones we’re watching there was a lot of concern; and really it just didn’t work.


“With 430 acres and a lot of it being wetland, we didn’t even make a dent on it. So, after a couple
of years, we stopped doing anything.”


The mosquitoes weren’t always that bad, and guests at the zoo didn’t seem to mind that much. A
little mosquito repellant and everyone was good to go.

Then along came West Nile virus. Like a lot of zoos, Binder Park put its birds inside – not good for
the birds – not good for the people who wanted to see the birds. A couple of years after West Nile
was detected, a vaccine that was developed for horses and it was used on birds, too. Jenny Barnett says it
seems to work.


“So far we’ve had success with it and we are continuing to do testing on their blood to check for
West Nile virus and we’ve been successful so far, but we will continue to vaccinate. We’ll
vaccinate our horses, and we’ll always worry about it, but a lot of the birds do have immunities right
now.”


And it’s assumed a lot of people also have immunity to the West Nile virus. They probably have been
infected and didn’t even know it. People with immune deficiencies are at much greater risk, but
many healthy adults can contract it and dismiss it as a summer cold or bad allergies, but health
officials say do what you can to avoid being bitten. Now, they’re not saying that you shouldn’t go
outside. They’re just saying if you do go outside, you should use a mosquito repellant with DEET.
Natasha Davidson is with the Health Department in Ingham County Michigan. She says don’t
douse yourself in repellant. A light spray will do.


“And if you’re applying it to your face, you should really put it on your hands first and then apply it.
And even applying it to children, it’s better an adult put on their hands first and then apply it to a
child.”


Davidson says don’t use DEET on children six months of age and younger, and don’t put it on
toddler’s hands because they’ll just put them in their mouths. Ugh… not good to ingest DEET.
Some advise using a cream based repellant because it doesn’t go into the skin as easily, and stays
on the surface where it can do some good. It’s also a good idea to wear loose fitting clothes with
long sleeves and long pants. I know it’s hot, but it beats scratching mosquito bites for days on end.
Natasha Davidson says even on heavy mosquito years like this one you can help reduce your
exposure to the pest.


“Other things that people can do is to make sure they have no standing water in their yard,
whether it’s at home or at a vacation property. Empty your gutters. Make sure that they’re clean
so that the water flows through. Make sure that you don’t have flower pots that have standing
water in it, old tires, different things like that. If you have a bird bath, change the water in the bird
bath once a week.”


Beyond that there’s not much you can do. Mosquitoes aren’t going away and with a little
preparation…


(sound of spray)


…you should just go ahead and enjoy the outdoors.

Ethanol Fuel Stations to Double?

A bill being introduced in Congress could double the number of gas stations in the United States that sell E-85 ethanol fuel. The GLRC’s Erin Toner reports:

Transcript

A bill being introduced in Congress could double the number of gas stations in the United States
that sell E-85 ethanol fuel. The GLRC’s Erin Toner reports:


Congressman Mike Rogers of Michigan says the federal government should subsidize new
ethanol pumps at gas stations. Ethanol is made from corn or other kinds of plants. Rogers says it
would cost 20 million dollars to double the number of gas stations selling E-85; a blend of 85
percent ethanol and 15 percent gasoline:


“Our big three – General Motors, Ford and Chrysler – are building total almost a
million E-85 cars, so they’ve done their part. Now we need to do our part and get these
gas stations out across America selling E-85 gas.”


Rogers says the government should also boost subsidies for ethanol research to improve the
production process. He says if that happens, within five years, ethanol fuel could cost drivers
one dollar a gallon. But critics say taxpayers would be footing the actual cost of making ethanol.

Mud Snail Slimes Into Great Lakes

A foreign invasive species is spreading to new areas. It’s a snail that could spread in huge numbers and compete with fish for food. The GLRC’s Mike Simonson reports:

A foreign invasive species is spreading to new areas. It’s a snail that could
spread in huge numbers and compete with fish for food. The GLRC’s Mike
Simonson reports:


The New Zealand Mudsnail has made its way to Lake Superior. It had already
been identified in Lake Ontario. These snails become dense on a river or lake
bottom. Minnesota Seagrant Aquatic Species expert Doug Jensen says it’s like
having half a million in the space of a bathtub. They can squeeze out bottom
dwelling organisms that fish eat. Jensen says native fish eat New Zealand
Mudsnails, but the fish don’t digest them:


“They can pass through the guts of fish and potentially waterfowl and then
survive that situation and then breed in a new location, where ever they’re
deposited. They reproduce asexually. They produce clones of themselves; they
don’t need a male to establish a new colony.”


The snails are the latest on a long list of invasive species that have likely been
carried in by foreign ships.

Group to Sue Epa Over Beach Water Quality

An environmental group is planning to sue the government because it’s
too slow to warn people about high levels of bacteria in the water.
The environmental group says government standards for beach closings
are outdated. The GLRC’s Rebecca Williams reports:


The current beach water standards haven’t been revised for 20 years.
Some scientists and environmental groups say that’s endangering public
health.


Nancy Stoner is with the Natural Resources Defense Council. Her group
recently announced plans to sue the EPA for failing to protect
beachgoers from contaminated water. Stoner says the current standards
are based on outdated methods.


“They’re too slow. They tell people whether the water quality was good
24 or 48 hours before they’re in the water, not whether it’s good
today. And they focus on bacteria only, not on viruses, not on
parasites like cryptosporidium and giardia.”


Stoner says the EPA failed to meet a deadline for issuing revised
standards. An EPA spokesperson says the agency is in the process of
revising the standards based on the latest science.

Gao: Flaws in Global Warming Program

The watchdog agency for Congress says the president’s greenhouse gas reduction
programs don’t hold companies accountable. Four years ago, the Bush Administration
unveiled its plan to cut greenhouse gas emissions. At the time critics said the voluntary
programs simply wouldn’t work. The GLRC’s Mark Brush has more:


In 2002 president Bush announced a plan to cut the nation’s output of heat trapping
gases:


“My administration is committed to cutting our nation’s greenhouse gas intensity, how
much we emit per unit of economic activity, by 18% over the next ten years.”


What followed were two government programs that called on businesses to voluntarily
reduce their greenhouse gases. The Government Accountability Office recently put out a
report on those two programs run by the Department of Energy and the EPA. It found the
businesses that volunteered make up only half of all greenhouse gas emissions in the US.
It also found there’s no system in place to verify whether companies are meeting the
goals of the programs. The GAO recommends the agencies make policies that will track
a company’s progress, and hold companies accountable if they don’t meet their goals.

A MAD DASH FOR TRASH (Short Version)

When college students head home for the summer, the unmatched dishware and stuffed animals
that filled dorms often become trash, but a number of schools are turning stadiums into sale
grounds and hawking the remnants of college life. The GLRC’s Jennifer Szweda Jordan has
more:


When college lets out, dumpsters get overwhelmed with tons of students’ belongings, but not at
a few major universities. Five years ago, Penn State started getting students to donate their
goods. The school invited the local United Way to sort area rugs and shoes, to run a sale and
to reap the profits. Notre Dame and West Virginia University followed suit.


Paul D. Ruskin is a Penn State spokesman.


“It is a solution that has no downside. It keeps things out of the landfill. It keeps down Penn
State operating costs. It makes nice items available to families at a good price. And it helps a
charitable organization.”


It’s also a big draw. More than five-thousand people attended Penn State’s event this year.
Other universities are reporting similar turnouts.

A Mad Dash for Trash

Each spring when college students leave their dorms, they leave behind tons of unwanted furniture, rugs, and other stuff that just didn’t make the cut for the trip back home. At one time, it all would’ve ended up in a landfill. In recent years, some universities have been sorting out the usable items and holding huge yard sales. The GLRC’s Jennifer Szweda Jordan took her pocketbook and her microphone to one of those big sales:

Each spring when college students leave their dorms, they leave behind tons of unwanted
furniture, rugs, and other stuff that just didn’t make the cut for the trip back home. At one time,
it all would’ve ended up in a landfill. In recent years, some universities have been sorting out the
usable items and holding huge yard sales. The GLRC’s Jennifer Szweda Jordan took her
pocketbook and her microphone to one of those big sales:


“Welcome to the fifth annual Trash to Treasure sale. Let the excitement begin.”


At 7:30 a.m., the gates to Beaver football stadium at Penn State are hoisted and thousands of
people run through six metal corrals. It’s a mad dash for CD players, stuffed animals, and other
remnants of college. Sixty-six tons… of stuff. What’s with kids leaving behind all this, and that
$215 chichi bronze silk purse – with tag intact?


“No one wants to take it home. I mean to fit all that stuff in a car – it’s awful. It’s really hard to
do. So I mean if you can’t fit it you might as well leave it and leave it for somebody else.”


Erin Horning is a college student herself. She’s here for the fourth year in a row.


“I was a freshman in college this past year so I came here to get all my college stuff from the
students that already left like irons, and oh, furniture….”


Penn State’s Environmental Strategies Team started the Trash to Treasure sale to keep leftover
lumber and coffee mugs out of the waste stream. Other major colleges around the country are
following suit, including Notre Dame and West Virginia University. Penn State spokesman Paul
D. Ruskin says it also saves the school 43-hundred dollars in hauling costs.

“We had a problem. We had 60 to 70 tons of usable material left behind. And the solution which
we found was to have this massive sale and to have the items donated to this sale. And to have
United Way take over and manage the sale.”


The charity brings in 300 volunteers who sort sale items over a few weeks. Bethany Heim
volunteered for 19 shifts. She and her husband are also first in line for the sale, having arriving
around midnight.


(sound of people in stadium)


“I came for a vacuum. It started as a joke when I started volunteering here three weeks ago.
And now I found THE vacuum.”

Heim says that besides keeping trash out of landfills, the sale benefits the community in other
ways.


“They have stuff put away for Katrina victims. I’m sure some of it will make its way to the flood
victims in New England. And just that it’s not on the sides of the streets – ’cause driving
through town when you see all the furniture from the college kids on the sides of the streets.”


Penn State tries to bring more customers in every year. The school’s Paul D. Ruskin admits that
the county market for box fans has already been saturated. So now it’s trying to generate
enthusiasm with gimmicks. Like this year’s attempt to break the record for the most people
wearing Groucho Marx masks. The effort fell 138 people shy. Still, the United Way netted 45,000 dollars. And as for Bethany Heim…


“I got my vacuum!”


And with happy customers like that, universities are starting to realize that selling all the college
student leftovers is good P.R. as well as just good sense.

Sharing Prairie Chickens

Most of the native prairie east of the Mississippi is now farmland, but there are still a few isolated spots where remnants of prairie survive… and with them a prairie icon… the greater prairie chicken, but prairie chickens need a lot of habitat… and in places such as Illinois, Wisconsin and other states, only a few hundred birds survive.

Most of the native prairie east of the Mississippi is
now farmland, but there are still a few isolated spots
where remnants of prairie survive; and with them a
prairie icon: the greater prairie chicken. But prairie
chickens need a lot of habitat, and in places such as
Illinois, Wisconsin and other states, only a few
hundred birds survive. One state is having better
luck, and some of its birds are being moved to help
revive other prairie chicken populations. The GLRC’s
Dan Gunderson reports:


The prairie chickens are ghostly shapes in the grey
predawn light of this spring morning.


(sound of prairie chickens in)


The cocks cackle as they fight off other males. They
inflate the orange sacks on their necks and make a
mournful echoing sound. Tail feathers erect they strut
about trying to impress the hens, who sit quietly
watching.


This 5,000 acre chunk of native prairie in Minnesota
has never been plowed. The prairie chickens have
always lived here. Today it’s owned by the Nature
Conservancy and known as the Bluestem Prairie.
Brian Winter manages the land. This morning he’s in a
small plywood blind counting prairie chickens on their
booming ground. About 40 males are strutting their
stuff.


“In Minnesota it’s a success story and we hope it gets
to be an even more successful success story than what it is
right now.”


Genetic diversity is one of the keys to a species
survival. In many states, prairie chickens are so
isolated the gene pool becomes weak. In Minnesota
there are flocks of prairie chickens along the western
edge of the state. Brian Winter says those flocks are
close enough to keep the gene pool from getting
stagnant.


“So there’s interbreeding as birds disperse in the fall.”


(sound of chickens tussling)


“Nice fight just took place right there. The research that’s been done looking at the genetics shows the
Minnesota population is one of the best in terms of
genetic diversity.”


Brian Winter says 20 years ago there were an
estimated 2,000 prairie chickens in Minnesota.
Today the population is approaching 10,000. The
prairie chicken is stable enough in Minnesota that
there’s been a limited hunting season the past two
years. In the past few years, several hundred
Minnesota chickens have helped rebuild populations
in North Dakota, Illinois and Wisconsin. Later this
summer, Minnesota prairie chickens will be captured
and moved by the Wisconsin Prairie Chicken Society,
in an effort to save a population declining in size and
genetic diversity.


Dave Sample with the Wisconsin DNR says the state
hopes to set aside 15,000 acres of grassland for
prairie chicken habitat in the next ten years. But he
says the birds won’t survive without a genetic infusion.


“In order to increase genetics in a compromised
population you do need to bring an infusion in from
outside. You pretty much have to go where genetics
are good and bring those birds in to mix with ours.”


Sample says there’s no guarantee the Wisconsin
prairie chicken population will survive, but he thinks
expanding the genetic pool will be a big step in the
right direction.


Earl Johnson is Regional Wildlife Manager for the
Minnesota Department of Natural Resources. He
says the prairie chicken success reflects a
conservation success. Johnson says the federal
Conservation Reserve Program has turned thousands
of acres of marginal farmland back into grassland.
That makes good prairie chicken habitat. Johnson
says Minnesota is very fortunate to have a healthy
prairie chicken population.


“What’s the long term future for the prairie chicken? I’d hate to guess, but we are happy to help any states
that want our assistance by transplanting birds.”


Johnson calls the prairie chicken the prairie poster
child. Hundreds of people come from across the
country every spring to sit in blinds and watch the
mating dance. Johnson says interest is growing every
year. At the Bluestem Prairie, the Nature
Conservancy blinds are full almost every day during
the spring. Brian Winter says people from every state
have traveled here to see the spring spectacle unique
to the prairie grassland.


Despite its success, the prairie chicken population is
only as stable as its habitat. Winter says the prairie
chicken may be the most visible prairie resident, but
what’s good for the prairie chicken is good for many
other species as well.


“It’s going to be meadowlarks and bobolinks and
mallard ducks and a whole variety of grassland birds
that just require grassland habitat to survive, and
without it they’re just not going to be there.”


And that’s going to require larger grassland areas.
Too much of the prairie has disappeared in many
states to support healthy numbers of prairie chickens.
That means if the prairie chicken is to survive more of
the marginal farmland, the poorer quality farmland,
needs to be returned to prairie.
